At Capital Air (www.capitalair.co.za), we supply premium AUX air conditioners—designed for all-season comfort, offering powerful cooling in summer and efficient heating in winter. If you own an AUX aircon from Capital Air, you’re already halfway to a cosier, more energy-smart winter. You just need to tap into its full potential.

In this post, we’ll explore how to heat your home with your AUX aircon, whether it’s cost-effective, and why it might be the safest, cleanest option for winter warmth.

Can Your Aircon Heat Your Home?

Yes, absolutely. One of the biggest misconceptions about air conditioners is that they’re only for cooling. AUX air conditioners, available exclusively through Capital Air, are built for both. Whether you have a Midwall Split Unit, a Floor Standing Unit, or a Commercial Cassette, all our models come with heating and cooling functions, giving you full temperature control at the push of a button.

AUX inverter air conditioners utilise advanced inverter technology that not only heats the air but maintains a stable, even temperature throughout your space. Models such as the AUX Mirror Series, AUX Inverter Series, and AUX Fixed Speed Series are designed for smooth, efficient performance in both warm and cold conditions.

If you’re using a ducted or underceiling unit in a commercial space or large home, rest assured the same applies. These systems are just as capable of providing reliable, comfortable heat when the temperature drops across South Africa.

Is AUX Aircon Heating More Affordable?

It may surprise you, but yes—AUX inverter air conditioners from Capital Air are often cheaper to run than traditional heating appliances. You can enjoy a warm, comfortable space for a fraction of the cost of electric or gas heaters.

Let’s break it down:

Traditional electric or gas heaters are energy-hungry, and their heating is often localised—warming only the area directly in front of them. An AUX inverter aircon, on the other hand, utilises precise temperature regulation to deliver warmth efficiently, consuming less energy over time.

The Coefficient of Performance (COP) Advantage

AUX air conditioners are designed to be super-efficient. Thanks to their high Coefficient of Performance (COP) ratings , they can produce significantly more heat using less electricity.

Think of COP as a measure of how much heat you get for every unit of power used. For example:

• A COP of 3 means the aircon gives you 3 units of heat for every 1 unit of electricity it uses

• Traditional heaters typically give you only 1 unit of heat per unit of electricity

That’s a big step up. You stay warm while saving on energy bills—a major advantage with South Africa’s rising electricity costs.

Even Heat Distribution

AUX air conditioners feature advanced airflow technology that distributes warm air evenly throughout the room. This means:

• No cold corners

• No need to run multiple appliances to keep the whole space warm

• Consistent comfort from wall to wall

Other Benefits of Using Your AUX Aircon in Winter

Aside from energy efficiency and steady warmth, using your AUX Air Conditioner from Capital Air in winter has several less obvious perks worth celebrating:

Conquer Flu Season with Cleaner Air

Many AUX aircon units feature advanced filtration systems, capturing dust, bacteria, and allergens. This helps reduce the spread of airborne viruses during flu season. Breathe easier while you stay warm—a win for your whole household.

Pure Comfort, All in One

The post Stay Cool and Comfortable with Capital Air: A Guide to Choosing the Right AUX Air Conditioner appeared first on Capital Air.

At Capital Air (www.capitalair.co.za), we supply premium AUX air conditioners—a globally trusted brand known for innovation and reliability. Why not find the perfect match for your comfort this Valentine’s Day? Let’s explore the differences between inverter and non-inverter air conditioners and see which suits your needs.

The Basics: What Is an Inverter Air Conditioner?

An inverter air conditioner, often referred to as an energy-saving aircon, operates differently from traditional models. It uses a variable-speed compressor to maintain a steady temperature by adjusting its speed rather than turning the compressor on and off. This means the air conditioner uses only the energy needed to cool or heat a room, preventing sudden spikes in energy consumption.

AUX inverter technology features include :

• Energy-saving frequency adjustment – The compressor adjusts its frequency based on temperature differences, saving power and energy

• Powerful cooling mode – The compressor starts at high frequency to quickly improve cooling efficiency

• iFeel technology – Adjusts the air conditioning temperature according to the ambient temperature sensed by the remote control

Inverter technology also results in quieter operation and more consistent temperature control—perfect for bedrooms, home offices, and living spaces where comfort matters most.

Non-Inverter Air Conditioners: The Traditional Choice

Non-inverter air conditioners use a fixed-speed compressor that cycles on and off to regulate temperature. While they’re usually less expensive upfront, they consume more energy, leading to higher long-term costs. Non-inverter units can also be noisier, as the compressor constantly switches between running and stopping, which can disrupt a peaceful environment.

For budget-conscious buyers or spaces where the aircon is used infrequently, a non-inverter model from AUX (available through Capital Air) may still be a practical choice. However, for daily use, the benefits of inverter technology quickly outweigh the initial savings.

The Energy Efficiency Debate

Energy efficiency is a major factor in the inverter vs non-inverter debate. Inverter air conditioners are significantly more energy-efficient than non-inverter models, resulting in lower energy bills and a reduced carbon footprint.

AUX inverter models feature high CSPF (Cooling Seasonal Performance Factor) ratings :

• CSPF ratings up to 5.32 W/W on select models

• Energy Star levels ranging from 3 to 5 stars

• R32 refrigerant – More environmentally friendly with lower global warming potential

Non-inverter aircons consume more energy due to the compressor’s constant cycling, especially over long periods. With South Africa’s rising electricity costs, the energy savings from an inverter unit can make a meaningful difference to your monthly budget.

Noise Levels: A Matter of Peace and Quiet

Inverter air conditioners are significantly quieter because they adjust compressor speed instead of switching off entirely. This provides smoother, more consistent operation and a more peaceful environment.

AUX inverter models offer impressive noise control :

• Indoor noise levels as low as 22 dB on select models

• ODU low noise – Outdoor units designed for good sound quality

• Multiple fan speed options for customized quiet operation

Non-inverter air conditioners, with frequent on-and-off cycling, can be much louder, creating noise disturbances that affect comfort—particularly in bedrooms, nurseries, or study areas.

Additional AUX Inverter Features That Matter

When you choose an AUX inverter air conditioner from Capital Air, you’re getting more than just energy savings. Key features include :

• 4-Way Air Flow – Even distribution of cool or warm air throughout the room

• Golden Fin – Corrosion-resistant coating that protects the outdoor unit, especially important in coastal or humid areas of South Africa

• 4-Step Automatic Self-Clean – Keeps the indoor unit clean and hygienic, reducing maintenance needs

• Wide Voltage Operation – Handles voltage fluctuations common in many South African areas

• Easy Installation – Designed for straightforward setup by qualified technicians

Cost: The Initial Investment vs Long-Term Savings

Due to their advanced technology, inverter air conditioners generally have a higher upfront cost. However, the savings in energy bills over time can outweigh this initial investment.

Non-inverter models, while more affordable initially, tend to be less energy-efficient, potentially leading to higher ongoing costs. If you’re looking for a budget-friendly option, a non-inverter air conditioner may not be the best choice long-term.

Finding the Perfect Match

Like finding the perfect partner, choosing the right air conditioning system is about balance and compatibility. Inverter and non-inverter aircons offer distinct advantages, and your choice will depend on your specific needs and preferences.

An AUX inverter air conditioner could be your ideal match if you:

• Prioritise energy efficiency and long-term savings

• Want quieter operation for bedrooms or study areas

• Need consistent temperature control for comfort

• Plan to use your aircon daily or for extended periods

• Value features like self-cleaning and golden fin protection

It’s perfect for maintaining a stable, comfortable environment whether you’re working, relaxing, or enjoying a cosy Valentine’s evening indoors.

A non-inverter air conditioner might suit your needs if you:

• Are on a tighter initial budget

• Use the aircon only occasionally (e.g., guest rooms, seasonal use)

• Can handle some noise and temperature fluctuation

• Need a secondary unit for a less frequently used space

However, skipping your annual air conditioning service can quietly lead to problems over time. At Capital Air (www.capitalair.co.za), we supply premium AUX air conditioners, and we know that even the best units need regular care to perform at their best. From rising energy bills to poor cooling and unexpected breakdowns, small issues inside the system can build up without you realising it. Regular servicing helps keep everything running smoothly, ensuring your AUX air conditioner continues to keep your home comfortable when you need it most.

Why Annual Air Conditioning Servicing is Recommended

Air conditioning systems work harder than most people realise, especially during South Africa’s warmer periods when they may run for several hours each day. Over time, dust, debris, and general wear can affect internal components and reduce efficiency.

An annual service allows a qualified technician to clean, inspect, and test the system properly. During this process, they can identify minor issues early and resolve them before they develop into larger problems.

In many ways, maintaining your air conditioning system is similar to servicing a car. Even if everything appears to be working well, regular maintenance helps prevent unexpected faults and keeps the system operating efficiently.

Capital Air recommends that all AUX air conditioners receive an annual service to maintain warranty validity and ensure peak performance.

What Can Happen If You Skip Your Annual AC Service?

Skipping your annual service may not cause immediate problems. In fact, your system may continue to operate for quite some time. However, the effects of missed maintenance often appear gradually and can impact both comfort and running costs.

Higher Energy Bills

One of the earliest signs of a poorly maintained system is an increase in your energy bills. When filters and internal components become dirty, the system must work harder to cool your home.

Because of this additional strain, the unit consumes more electricity to maintain the same temperature. Over time, this can lead to noticeably higher running costs—even if your cooling habits have not changed. For AUX inverter models designed to save energy, a lack of maintenance can erase those intended savings.

Reduced Cooling Performance

Another common issue is a decline in cooling performance. If airflow becomes restricted due to clogged filters or dirty coils, the system may struggle to distribute cool air evenly throughout your home.

You might notice certain rooms taking longer to cool or feeling warmer than others. While the system may still be running, it will not provide the same level of comfort it once did.

Unexpected Breakdowns

Small internal faults often go unnoticed when regular servicing is skipped. Components may loosen, electrical parts may wear out, or refrigerant levels may drop gradually over time.

Eventually, these problems can lead to a sudden breakdown—often during the hottest part of the South African summer when the system is under the most pressure. When this happens, many homeowners find themselves urgently searching for air conditioning repair, which can be far more disruptive and costly than routine servicing.

Poor Indoor Air Quality

Air conditioning systems do more than cool the air; they also help circulate and filter it. When the system is not properly maintained, dust, pollen, and other particles can accumulate inside the unit.

Instead of improving air quality, the system may begin circulating these particles throughout your home. This can make indoor air feel less fresh and may be particularly uncomfortable for people with allergies or respiratory sensitivities. Many AUX models feature advanced filtration—but filters need regular cleaning to work effectively.

A Shorter Lifespan for Your System

Air conditioning systems are designed to last many years, but only when they are properly maintained. When servicing is skipped, additional strain is placed on key components—especially the compressor, which is the heart of your unit.

Over time, this extra stress can shorten the overall lifespan of the system, meaning you may need to replace it much sooner than expected. With AUX’s 5-year compressor warranty, regular servicing ensures you get the full benefit of that protection.

Signs Your AUX Air Conditioner May Need Servicing

Sometimes your air conditioning system will give clear signs that it needs attention. If you notice any of the following issues, it may be time to arrange a professional inspection through Capital Air:

• Weak airflow coming from the vents

• Unusual noises such as rattling, buzzing, or clicking

• Unpleasant odours when the system is running

• Unexpected increases in energy bills

• The unit is turning on and off more frequently than usual

• Water leaking from the indoor unit

• The system struggles to reach the set temperature

These signs often indicate that the system has gone too long without proper maintenance.

How Often Should You Service Your Air Conditioner?

Most manufacturers—including AUX—recommend servicing your air conditioning system at least once a year. For units that run frequently or are used in dusty environments (common in many parts of South Africa), twice-yearly servicing may be beneficial.

Important warranty note: AUX’s 5-year compressor warranty requires that the unit be:

• Installed by a qualified installer

• Serviced annually by a registered technician

• Registered online with Capital Air

Skipping annual servicing can void your warranty, leaving you unprotected if a major fault occurs.

The Long-Term Benefits of Regular AC Maintenance with Capital Air

Keeping up with annual servicing offers several long-term benefits for both your home and your air conditioning system:

• Lower energy costs due to improved efficiency

• Better and more consistent cooling performance

• Reduced risk of sudden system breakdowns

• Improved indoor air quality for your family

• A longer lifespan for your AUX air conditioning unit

• Warranty protection maintained in full

• Peace of mind knowing your system is safe and reliable

Regular maintenance may seem like a small step, but it plays a significant role in protecting your system and avoiding costly repairs.

Conclusion – A Small Service That Prevents Big Problems

Skipping your annual air conditioning service might not seem like a major concern, especially if the system appears to be working normally. However, over time, missed maintenance can lead to higher energy bills, weaker cooling performance, unexpected breakdowns, and even voided warranties.

By scheduling regular servicing, you can keep your AUX system operating efficiently and avoid many of these issues. Professional air conditioning maintenance through Capital Air helps ensure your system remains reliable, comfortable, and ready to keep your home cool—whether it’s the height of summer or a mild winter’s day.

If your AUX air conditioner hasn’t been serviced in a while, now may be the right time to arrange a professional check.

Frequently Asked Questions

1. How often should an AUX air conditioner be serviced?

AUX air conditioners should be serviced at least once a year. Annual servicing is also a requirement to maintain the 5-year compressor warranty.

2. How long does an air conditioning service take?

A standard air conditioning service usually takes between 45 minutes and 1.5 hours, depending on the type of system and its condition.

3. When is the best time to service an air conditioner?

The best time to service your air conditioner is before the warmer months begin—typically in early spring (August to September in South Africa). This ensures the system is ready to handle increased use during the summer. However, servicing at any time is better than skipping it altogether.

4. Does skipping a service void my warranty?

Yes. AUX’s warranty (including the 5-year compressor warranty) requires annual servicing by a qualified technician. Skipping services can void your coverage.

5. Can I clean the filters myself?

Yes, cleaning the removable filters yourself every 2-4 weeks is recommended. However, a full professional service includes inspection of internal components, refrigerant levels, electrical connections, and drainage systems—tasks that require trained technicians.

The post What Happens If You Skip Your Annual Air Conditioning Service? A Capital Air Guide appeared first on Capital Air.

But over time, that outdoor unit collects dust, leaves, and grime—often without you noticing. At Capital Air (www.capitalair.co.za), we supply premium AUX air conditioners, and we know that even the best units can suffer when the outdoor component is neglected. What seems like a minor issue can slowly affect performance, increase your energy bills, and even lead to avoidable repairs.

What Happens to Your Outdoor AUX Unit Over Time?

Your outdoor unit is constantly exposed to the South African environment. Unlike indoor components, it faces everything from dust storms to seasonal weather changes.

Here’s what typically builds up:

• Dust and fine particles from the air (common in many parts of South Africa)

• Dry leaves, twigs, and debris blown by wind

• Pollution residue, especially in urban areas like Johannesburg or Pretoria

• Moisture, which can lead to grime and corrosion

• Grass clippings if you mow near the unit

• Pet hair and dander if animals rest near the unit

Even if it looks relatively clean from the outside, internal components like coils and fins can become clogged. And that’s where the real problem begins.

Important note for AUX owners: AUX units feature Golden Fin corrosion protection on many models, which helps resist damage in coastal or humid areas. However, even this advanced protection cannot compensate for severe neglect or physical blockage.

The Hidden Cost – Higher Bills Without You Realising

One of the most overlooked consequences is the impact on your electricity bill. With South Africa’s rising energy costs, every bit of efficiency matters.

When your AUX air conditioner works harder than it should, it consumes more power. This often happens gradually, so you may not immediately connect the dots.

What feels like a small oversight can quietly increase your monthly expenses—and shorten the life of your AUX unit.

Signs Your Outdoor AUX Unit Needs Immediate Attention

You don’t need technical knowledge to recognise when something isn’t right. Look out for these signs:

• Your AUX aircon is taking longer to cool the room than it used to

• Airflow feels weaker than before from the indoor unit

• You hear unusual noises (rattling, buzzing, or grinding) from the outdoor unit

• Visible dust, leaves, or blockage around or inside the outdoor unit

• A noticeable spike in electricity bills without changes in usage

• The outdoor unit feels extremely hot to the touch during operation

• The system shuts down unexpectedly on very hot days

Even one of these signs is enough to warrant a closer look.

Why “Now” Matters – Not Later

It’s easy to delay maintenance, especially when your AUX aircon is still working. But the problem with dust and debris is that they build up gradually and worsen over time.

Delaying cleaning means:

• Deeper internal blockage – Debris works its way further into the condenser coils

• Reduced efficiency over weeks or months – Each day of neglect adds to the problem

• Higher chances of component failure – Compressors fail when overheated

• Potential voided warranty – Neglect-related damage is not covered under AUX’s 5-year compressor warranty

Acting early is always simpler, quicker, and far more cost-effective. A 15-minute clean today can prevent a R5,000+ repair tomorrow.

Can You Clean It Yourself or Should You Call a Professional?

This is a common question, and the answer depends on what needs to be done.

Task	Can You Do It Yourself?	When to Call Capital Air
Removing visible debris (leaves, twigs)	Yes	–
Cleaning the surrounding area (2-3 feet clearance)	Yes	–
Gently hosing down the fins (low pressure)	Yes (carefully)	–
Internal coil cleaning with chemicals	No	Yes – requires training
Refrigerant pressure checks	No	Yes – requires certification
Performance inspection	No	Yes – professional assessment
Fan motor or compressor testing	No	Yes – specialist required

You can handle basic external cleaning, but deeper maintenance—especially for AUX units with Golden Fin coating (which can be damaged by harsh chemicals)—is best left to professionals to avoid accidental damage.

Warning: Do not use a high-pressure washer on your outdoor unit. The force can bend the delicate fins, causing more damage than the dirt itself.

How Regular Maintenance Protects Your AUX Air Conditioner

When your outdoor unit is clean and well-maintained, everything works better. AUX air conditioners are designed for efficiency, but they need a clean environment to deliver that performance.

You benefit from:

• Faster and more consistent cooling – No struggling against blocked airflow

• Lower electricity consumption – Your inverter technology can actually save you money

• Fewer unexpected breakdowns – Especially during peak summer months

• Longer system lifespan – A well-maintained AUX unit can last 10-15 years

• Warranty protection maintained – Annual servicing keeps your coverage active

• Quieter operation – No rattling debris or struggling fan motors

If you’ve invested in a premium AUX air conditioner from Capital Air, regular maintenance ensures you actually experience the performance you paid for.

Simple Habits to Keep Your Outdoor AUX Unit Clear

You don’t need to do much—just a few consistent habits can make a big difference:

• Keep at least 2–3 feet of clear space around the unit on all sides

• Remove leaves and debris weekly – especially during autumn

• Trim back bushes or plants that grow near the unit

• Avoid placing items (bins, furniture, tools) near the unit

• Check the unit after heavy winds or storms – debris accumulates quickly

• Be careful when mowing the lawn – angle the mower away from the unit

• Schedule professional servicing annually through Capital Air

• Consider a protective cover only when the unit is not in use for extended periods (never while running)

These small steps can prevent larger issues down the line.

Why Choose Capital Air for Your AUX Outdoor Unit Maintenance?

At Capital Air (www.capitalair.co.za), we don’t just supply premium AUX air conditioners—we help you keep them running at their best.

Conclusion – A Small Step That Makes a Big Difference

Most people don’t pay attention to the outdoor unit until something stops working—and by then, it’s usually more than just a quick clean. The truth is, a lot of common AC issues start small. A bit of dust, some blocked airflow, and the system is working slightly harder than it should. You don’t notice it immediately, but over time, it shows up in slower cooling, higher bills, or unexpected repairs.

Whether you’re using an AUX Mirror Series, AUX Inverter Series, or any other AUX air conditioner from Capital Air, keeping the outdoor unit clear is one of the easiest and most effective things you can do to protect your investment.

Don’t wait for a breakdown on the hottest day of summer.

Frequently Asked Questions

1. Will cleaning the outdoor unit reduce my electricity bill?

In many cases, yes. A clean AUX outdoor unit doesn’t have to work as hard, which means it uses less energy. Combined with AUX’s inverter technology, proper cleaning can lead to noticeable savings on your electricity bills—typically 10-15% or more on a neglected unit.

2. Is it safe to clean the outdoor unit myself?

You can remove visible dust and leaves from around and on top of the unit, and gently hose the fins with low pressure water. However, internal cleaning, chemical treatments, and component inspection should be handled by a professional from Capital Air.

3. How much space should be around the outdoor unit?

Ideally, you should keep at least 2–3 feet of clear space around all sides of the unit. This allows proper airflow and makes it easier for the system to function without restriction. Check your AUX installation manual for model-specific requirements.

4. Should outdoor AC units be covered to protect from dust?

Not while in use. Covering can restrict airflow and worsen performance—or even cause overheating. It’s better to keep the area clean rather than enclosing the unit. If you want to cover it during the off-season (winter), use a breathable cover and remove it before running the system again.

5. How often should I check my outdoor AUX unit?

A quick visual check once a week is ideal, especially during windy seasons or if you have trees nearby. A more thorough cleaning should be done at least every 3 months, with professional servicing annually.

6. Can a dirty outdoor unit void my AUX warranty?

Yes, potentially. Neglect-related damage—such as compressor failure due to overheating from blocked airflow—is not covered under warranty. Regular cleaning and annual professional servicing protect your coverage.

HVAC stands for Heating, Ventilation and Air Conditioning. It refers to the system used in homes, offices, shops, and commercial buildings to manage indoor climate. A typical commercial HVAC setup from Capital Air includes:

In South Africa, where temperatures can vary dramatically across regions and seasons, a well-functioning commercial HVAC system is crucial not only for comfort but also for maintaining healthy indoor air quality and protecting sensitive equipment, stock, or inventory.

Why Regular Maintenance Matters for Your AUX Commercial System

Regular HVAC maintenance is essential for peak performance and longevity. Here’s why:

• Boosts energy efficiency – Clean filters, coils, and components reduce power use and save on utility bills. With South Africa’s rising electricity costs, efficiency is critical.

• Prevents expensive breakdowns – Catching minor issues early avoids costly emergency repairs and business downtime.

• Maintains warranty requirements – AUX’s 5-year compressor warranty requires annual professional servicing.

• Enhances indoor air quality – Removes dust, allergens, and mould risks, keeping staff and customers healthy.

• Extends system lifespan – Routine care defers costly replacements—a well-maintained AUX unit can last 10–15 years.

Simple maintenance tasks – filter changes and clearing around outdoor units – paired with annual professional tune-ups through Capital Air, provide comfort, savings, and peace of mind.

8 Key Signs Your Commercial AUX HVAC System Needs Maintenance

Here are the eight warning signs that your Capital Air-installed commercial system needs attention:

Sign 1: Rising Energy Bills

One of the earliest signs of a struggling commercial HVAC system is an unexplained increase in your electricity bill. When components become dirty or worn, the system works harder and runs longer to maintain the same temperature.

What to do: Check your monthly utility statements. If usage has increased without changes to building occupancy or hours, schedule a professional inspection through Capital Air.

Sign 2: Longer Run Times

If your AUX commercial system used to cool a room in 15 minutes but now takes 30 minutes or more, something is wrong. This often points to:

• Clogged air filters restricting airflow

• Low refrigerant levels

• Dirty condenser coils on the outdoor unit

What to do: Check and replace filters first. If the problem persists, contact Capital Air for a professional assessment.

Sign 3: Uneven Temperatures

Are some offices freezing while others feel stuffy? Uneven temperatures across your commercial space indicate:

• Blocked or leaking ductwork

• Dirty filters restricting flow to certain areas

• Fan or damper issues

• An incorrectly sized system for your space

What to do: Note which areas are problematic and have a Capital Air technician inspect your ductwork and airflow balance.

Sign 4: Unusual Noises

Your commercial AUX system should operate relatively quietly. Listen for these warning sounds:

What to do: Don’t ignore unusual noises. Turn off the system and call Capital Air immediately—continued operation could cause severe damage.

Sign 5: Weak Airflow

If you place your hand near a vent and feel only a faint breeze, your system is struggling to move air. Common causes include:

• Clogged air filters (most common)

• Blocked or collapsed ductwork

• Fan motor problems

• Frozen evaporator coils

What to do: Replace filters first. If airflow doesn’t improve, schedule a professional duct and fan inspection.

Sign 6: Thermostat Problems

Your thermostat is the brain of your HVAC system. Signs of trouble include:

• The system doesn’t respond to temperature changes

• Wide temperature swings (too hot, then too cold)

• The system runs continuously without reaching set temperature

• Blank or flickering display

What to do: Check batteries and ensure the thermostat is clean and unobstructed. For persistent issues, a Capital Air technician can test and recalibrate or recommend a replacement.

Sign 7: Frequent Repairs

If you’re calling for service every few months, your system is telling you something. Occasional repairs are normal for an aging system, but frequent breakdowns indicate:

• Underlying issues were never fully resolved

• Multiple components are failing

• The system is undersized or poorly matched to your space

What to do: Keep a log of all repairs. If you’ve had three or more service calls in a year, ask Capital Air about a comprehensive system evaluation or replacement options.

Sign 8: System Age

Even the best AUX air conditioners have a lifespan. Consider this:

Modern AUX inverter systems offer significantly better energy efficiency than older units. Upgrading can reduce your commercial electricity bills by 30–50%.

Commercial HVAC Maintenance Tips to Keep Your AUX System in Check

Regular HVAC maintenance can save your business money on energy costs and prevent untimely equipment failure. Here’s a detailed guide to keeping your Capital Air-installed AUX system in top shape.

1. Monthly to Quarterly Checks
