How Often Should You Service Air Conditioning Units?

Most people don’t think about their air conditioning until it stops cooling or heating (air source heat pump air conditioning systems) properly, becomes noisy or the bills start climbing. The truth is, a simple annual service can prevent most of those issues. Regular air conditioning servicing should be done at least once a year, especially for commercial systems. In this guide, we’ll explore how often to service business / commercial air conditioning units and the simple signs that it’s time to book a service.

How Often Should You Service Air Conditioning Units?

Air conditioning systems with an output over 12kW, are legally required to be inspected at least once every five years, under EPB regulations. However, for the best performance, air conditioning units should be inspected, cleaned, and serviced at least once a year. Regular air conditioning servicing keeps your system working efficiently, improves air quality and extends the life of your unit.

How Often Should Commercial / Business Air Conditioning Units Be Serviced?

For most businesses, having your air conditioning serviced once every 12 months is usually sufficient. However, the more frequently your system is serviced, the lower the chance of unexpected breakdowns. If your air conditioning system is used for both cooling and heating, especially during the hotter months, servicing it twice or even three times a year is ideal.

Regular air conditioning maintenance helps identify issues you might not notice, such as dirty filters, worn electrical connections or blocked condenser coils. These small problems can make your system work much harder than necessary, increasing energy consumption and costs. A simple but effective tip is to note down the last time you cleaned or replaced your filter to keep your system running efficiently.

Clogged filters or indoor heat exchangers can cause the indoor fan coil unit to become noisy as it struggles to pull and push air through the system. Eventually, this lack of airflow can cause the fan motor to over-spin, leading to overheating and potential burnout of the motor and electrical components, resulting in costly repairs.

Blocked heat exchangers can also increase refrigerant gas pressure, which may cause the system to ice up, leading to water leaks. In severe cases, the refrigerant gas can turn into liquid and flood the outdoor compressor, resulting in catastrophic compressor failure and very high repair bills.

A well-maintained system doesn’t just cool or heat your space but it can also boost morale and output. Learn more in our guide on how commercial air conditioning improves employee productivity

Benefits of Servicing Commercial Air Conditioning Units More Frequently

Commercial air conditioning systems normally need at least one annual service and often more frequent attention depending on scale, type of system (split type / multi type / VRV or VRF type), complexity, running hours and the environment. Systems in industrial, retail or hospitality settings gather dirt quicker and run for longer periods, so wear builds up faster and more frequent air conditioning servicing pays off. 

At Chillaire, we recommend routine visits every six months for many commercial installations. We also offer planned maintenance contracts to manage service schedules.

What Are the Signs That My Air Conditioning Unit Needs Servicing?

You don’t always notice problems with your air conditioning unit until they get serious. Watch out for:

• Rising electricity bills even though your usage hasn’t changed
• The system struggling to reach the thermostat setting on really hot days
• The unit running almost non-stop or cycling on and off a lot
• Unusual noises, burning smells or leaks due to clogged indoor heat exchangers or filters
• Dirt or blockages on the outdoor heat exchanger condenser coil

If any of these happen, it’s a good idea to book an air conditioning service with an accredited surveyor. If your air conditioning is showing signs of age or frequent faults, our guide on when to replace your air conditioner can help you decide if it’s time for a new system.

Schedule a service with Chillaire if your unit shows any of these signs. Our engineers can catch problems early and save you money later.

How Can I Maintain My Air Conditioning Unit Between Servicing’s?

Maintaining your air conditioning unit or system between professional visits helps prolong its life.

• Check filters every month during heavy use and replace them if they look dirty.
• Keep the outdoor condenser clear of leaves and debris.
• Don’t close vents in rooms you’re not using.
• Set your thermostat earlier in the day to avoid lots of short on and off cycles.
• Listen for unusual noises and watch for strong smells, which can be an early warning.

Regular air conditioning maintenance between servicing will help you spot any small issues early.

How to Clean and Maintain HVAC Systems

Learning how to clean and maintain HVAC systems is one of the best ways to keep them safe, efficient and reliable all year round. So, what is HVAC maintenance? It’s the regular cleaning, inspection and servicing that ensures your equipment performs at its best while keeping energy costs under control. Without it, systems become less efficient, air quality suffers and unexpected breakdowns become more likely.

In this guide, we’ll explain why HVAC maintenance matters, what is done during HVAC maintenance, the simple steps you can take yourself and the benefits of using professional HVAC maintenance services. At Chillaire, we’ve been helping homes, businesses and industrial clients across the Midlands take care of their HVAC systems for more than 30 years, so you can trust that regular maintenance really does make a difference.

What Is HVAC Maintenance?

When we talk about HVAC maintenance, what we mean is the regular cleaning, inspection and servicing. This keeps your heating, ventilation and air conditioning systems working safely and efficiently.

HVAC stands for heating, ventilation and air conditioning. In simple terms, this system keeps you warm during winter and cool during summer, controlling the climate inside your building.

So, is it worth maintaining? Absolutely. Without proper care, these systems can affect your comfort, energy bills and even your health. Poorly maintained equipment can lower air quality, making it harder to breathe. Regular HVAC maintenance helps you avoid breakdowns and keeps the environment inside your premises healthy.

Is HVAC Maintenance Important?

There are plenty of benefits that come with keeping up a HVAC maintenance routine:

Safety
HVAC systems often run on electricity or gas. Having them checked each year is essential. Technicians look for electrical faults, gas leaks and carbon monoxide levels. Safety really is the top priority.

Indoor air quality
If the system is dirty, the air you breathe is dirty. Dust, mould and allergens can build up inside your ducts and filters. Maintenance makes sure your system is circulating clean air.

Lifespan
Equipment that’s blocked with dirt or never inspected will wear out faster. Regular maintenance extends the life of your system, protecting your investment.

Energy efficiency
A dirty system has to work harder, which means it runs longer and uses more power. Keeping everything clean and tuned reduces your energy bills.

Peace of mind
When all these points are covered, you can relax knowing your HVAC system is reliable, safe and ready for the season ahead.

DIY vs Professional HVAC Maintenance

Annual HVAC maintenance is an investment worth making. A system that is serviced properly not only uses less energy but also provides better comfort at lower costs.

Working with professional HVAC maintenance services is important because trained technicians can spot problems early and carry out repairs to keep everything running smoothly. Homeowners or business owners simply don’t have access to the specialist knowledge and tools required for a thorough service.

Professional HVAC Maintenance Services:

A typical annual HVAC service carried out by a professional technician should include:

• A full clean of the furnace or air conditioning unit
• Inspection of safety switches and devices
• Checking for cracks or damage in the heat exchanger
• Filter replacement
• Calibration of temperature and airflow controls
• Washing of the outdoor condenser coil
• Adjustment of fans and belts
• Inspection of drains and traps
• Testing of all electrical components 

This level of care ensures the system runs as efficiently as possible and reduces the chance of breakdowns at the worst time of year.

How can I Keep my HVAC System in Good Condition

There are a few simple maintenance tasks that are safe and effective for homeowners and business operators:

• Keep filters clean. Replace or wash them regularly to stop blockages and keep air moving freely.
• Keep vents open. Avoid placing furniture or curtains in front of them so the air can circulate.
• Clear around the outdoor unit. Remove leaves, rubbish or overgrown plants so airflow isn’t blocked.
• Cover smartly in winter. If icicles form above your unit, protect it with a piece of plywood placed on top. Otherwise, leave it uncovered so moisture isn’t trapped inside.

These steps will help extend the life of your HVAC system, improve efficiency and make professional servicing even more effective.
