air conditioner Fort Myers

Ever wonder what it is that your AC tech actually does when doing the maintenance on your unit? Here you have it – the complete air conditioner and HVAC checklist.

What we check when we inspect the indoor unit

1. Air Filters

Change your air filter monthly or bi-monthly. Things like smoking and pet dander and fur can add to the potential clogging of the filter so it becomes even more vital if you are a smoker or a pet owner.

2. Clean The Exterior

Wiping down the units outer shell can help keep dirt from creeping inside.

3. Burner Assembly

A small brush and vacuum can be used to clean the burner assembly if it is needed.

4. Blower Assembly

The blower wheel and motor, as well as their housing, kept clean can help ensure proper air circulation.

5. Ductwork

Check your ductwork for leaks which can cause your bill to skyrocket.

6. Combustion Blower Housing

Lint can accumulate in the combustion blower housing. Make sure to clean it regularly.

7. Evaporator Coil

Check the drain pan and do a flush and algae treatment to condensate the drain lines. Replace components as necessary.

8. Electrical Components

The electrical disconnect box and wire connections should be inspected and tightened as necessary.

9. Heat Exchanger and Heating Elements

Inspect both. If there is damage – replace it.

10. Ignition System

Clean and adjust as necessary.

11. Motor

If your HVAC unit has an aging motor, it will need to be lubricated. You should also ensure the fan’s belt is still good.

12. Safety Devices

You can perform inspection while it is running. Making sure all safety functions are operating properly.

13. Bulb Temperatures

Bulb temperatures should be checked both indoor and outdoor.

14. Carbon Monoxide

Consider installing a carbon monoxide detector to ensure your home’s safety.

15. Gas Pressure

Ensure the gas line and gas manifold are operating at the correct gas pressure.

16. Odors

Check for unusual odors. If you smell anything out of the ordinary call a professional.

17. Startup

Ensure the unit starts up normally and begins working immediately.


Check that your HVAC unit shuts off correctly.

19. Vents

Check your vents to ensure they are blowing air properly. If any aren’t, it could indicate a blockage. If not, there is likely a blockage.

20. Thermostat

Make sure your thermostat is operating correctly and the temperature is regulating.

Inspecting the Outdoor Unit – what we check

21.The Cabinet

Clear out any debris around the housing.

22. The Base Pan

Look at the base pan to check that its drains have no blockages.

23. The Coils

Keeping your coils clean is vital to the longevity of your unit. Clear any dirt, dust, leaves or built up debris.

24. Compressor and Tubing

Makes sure they do not show any damage, if they do – replace them.

25. The Control Box

This includes contactors, circuit boards and several other components you’ll see in the box. Check them to make sure they are all connected properly and have no damage visible.

26. Fan Motor and Blades

Inspect motor and blades for any wear and tear. Check the belt tension if necessary.

27. Refrigerant

It is important to the function of your system to keep the refrigerant level within range. Otherwise, your unit will have to work harder than necessary jacking up your bill and shortening its lifespan.

Regular maintenance keeps your HVAC in good shape and prolongs the life of the unit itself. Eventually, all systems do need to be replaced. If yours is over 10 years old the newer units are now much more energy efficient. Purchasing a new one could save your money in the long run.
