Commercial HVAC Preventative Maintenance Checklist

Performing regular preventative maintenance on your commercial HVAC system is one of the best ways to keep it running smoothly and avoid costly repairs down the road. 

If you own an HVAC system, you’re likely aware it’s a pretty complex piece of equipment, which means that a lot can go wrong if it’s not functioning properly. To help you maintain your commercial HVAC, we’ve put together this preventative maintenance checklist.

Preventative HVAC Maintenance Checklist

1. Check the air filters and replace them as needed.
2. Inspect the blower belt and tighten or replace it as necessary.
3. Lubricate all moving parts.
4. Clean the condenser coils.
5. Inspect the evaporator coils and clean them when necessary.
6. Check the refrigerant level and add more as needed.
7. Inspect the ductwork for leaks and repair if needed.
8. Test the thermostat and calibrate as needed.
9. Schedule a professional inspection and tune-up at least once a year. 

Following this simple preventative maintenance checklist can help keep your commercial HVAC system running smoothly. 

Let’s take a closer look at specific items to understand what they entail.

Check and Change Air Filters

One of the most important things you can do to maintain your HVAC system is to check and change the air filters regularly. 

Depending on your filter type, the filter should be changed anywhere from every month to every few months. Not only will this help keep your air quality high, but it will also prolong the life of your HVAC system.  

Inspect Blower Belt 

The blower belt is responsible for spinning the blower wheel, which moves air through the system. Over time, the belt can become worn or loose and must be tightened or replaced. 

This is a relatively simple task that you can do yourself, but if you’re not comfortable doing it, you can always call a professional.

Program Thermostats

Thermostats are one of the most important components of any HVAC system. They control the temperature of your home or business and can save you money on your energy bills by ensuring that your system is only running when needed. 

If you have a programmable thermostat, check it regularly and ensure it’s programmed correctly. If you don’t have a programmable thermostat, now might be a good time to consider investing in one. 

Schedule Annual Maintenance 

Following the checklist gets you on the right track, but we also recommend scheduling an annual maintenance visit from a qualified technician. 

During this visit, they will thoroughly inspect your entire system and make any necessary repairs or adjustments.
