Commercial HVAC Maintenance Checklist

Commercial HVAC systems integrate heating, cooling and ventilation components to maintain the indoor climate in commercial buildings. Because they rely on many interconnected components, it is essential they are well-looked after to keep everything running smoothly.

A preventative approach to commercial HVAC maintenance helps avoid the “domino effect”. A minor issue, such as a worn belt or blocked filter, puts extra strain on other components and eventually leads to a costly breakdown.

At Chillaire, we have over 30 years of experience working with commercial and industrial HVAC systems. Many of the breakdowns we attend could have been avoided with routine maintenance and servicing. Here, we’ll share a commercial HVAC maintenance checklist and explain why investing in a maintenance contract can save your business time and money.

What Happens Without Regular Commercial HVAC Maintenance?

Without regular maintenance, commercial HVAC systems gradually become less efficient and more likely to break down. Small issues that are ignored can quickly turn into expensive repairs for your business.

• Higher energy bills as dirty filters, blocked coils and restricted airflow force the system to work harder
• Unexpected breakdowns when minor faults are left unresolved and develop into major failures
• A shorter system lifespan caused by increased wear and tear on critical components
• Compliance risks if essential F-gas leak checks, gas safety inspections or TM44 assessments are missed
• Invalidated manufacturer warranties due to a lack of documented routine servicing

Like a car, your HVAC system needs regular servicing and maintenance to keep it running reliably and to avoid unnecessary costs.

What is Planned Commercial HVAC Maintenance?

Planned maintenance for commercial HVAC maintenance involves regular servicing under a scheduled agreement. Rather than waiting for a breakdown, certified engineers inspect, clean and test your HVAC unit at set intervals throughout the year. 

At Chillaire, planned maintenance runs under annual service maintenance agreements. We contact you when a service is due, and our engineers follow a comprehensive maintenance checklist to ensure every component is inspected, tested and operating efficiently.

Commercial HVAC maintenance checklist:

• Air filters inspected and Fascia’s cleaned or replaced
• Evaporator and condenser coils cleaned
• Refrigerant levels and operating pressures checked
• F-gas leak checks completed and recorded
• Condensate drains and drip trays cleared
• Electrical connections, wiring and controls inspected
• Thermostats and BMS settings tested 
• Fan motors, bearings and belts checked for wear
• Heat exchangers, pipework and insulation visually inspected
• Airflow measured across vents and returns

We offer a range of planned maintenance agreements to suit businesses of all sizes. You can read more about how our planned maintenance agreements work and choose the level of cover that’s right for your business.

What Does a Commercial HVAC Maintenance Contract Include?

A commercial HVAC maintenance contract should do more than schedule routine servicing. It should help reduce downtime, simplify compliance and ensure your system is maintained by qualified engineers throughout the year. Before choosing a provider, check your agreement includes the following:

• Scheduled servicing managed for you: Your provider should contact you when a service is due and perform preventative maintenance (PPM) visits around your operations.
• Full reporting: Every visit should produce a detailed service report with clear pricing for any recommended repairs.
• Flexible agreement levels: Call-outs and consumables can be included, so the contract matches your site and budget.
• Qualified engineers: Look for F-Gas certification, City & Guilds qualifications and Gas Safe registration for heating work.

At Chillaire, our planned maintenance contracts also include a 24-hour breakdown service, 7 days a week, 52 weeks a year, with an out-of-hours emergency line for contract customers.

Routine Commercial HVAC Checks Your Team Can Carry Out

Although servicing should be left to qualified engineers, your team can still carry out simple routine checks to spot signs of wear, damage or poor performance between maintenance visits.

• Listen for unusual noises, vibrations or smells when units start up
• Verify thermostat settings and room temperatures across different zones
• Keep vents and returns clear of furniture, stock and dust
• Clear leaves and debris around outdoor units
• Log performance changes and unexpected rises in energy use

Report anything unusual to your HVAC maintenance provider straight away. A strange noise today is often a breakdown next month.

How Often Should Commercial HVAC Systems Be Serviced?

Air conditioning and heat pump systems, as well as gas-fired, oil-fired and LPG heating systems, should be inspected, cleaned and serviced at least once a year. At Chillaire, we recommend a visit every six months in most commercial settings. This protects your systems’ life expectancy and keeps them running at maximum energy efficiency. Having an annual service also maintains manufacturer warranties. Commercial premises with high heating and cooling needs such as commercial kitchens and manufacturing facilities may need more frequent maintenance and servicing.
