Inspecting Your Air Conditioner

It is imperative to regularly inspect your air conditioning system to make sure that it operates smoothly. With temperatures starting to rise, it is important to do pre-season maintenance in order to avoid your air conditioner failing in severely hot weather and to also keep your energy bill from soaring. While a lot of the components can only be inspected by a professional service technician, some of the inspection you can do yourself. Read on to find out what to inspect to ensure that your HVAC system is operating efficiently this summer!

AIR FILTERS

One of the most important maintenance tasks you can perform for your HVAC system is to check your air filters. It is recommended to clean or replace air filters every 90 days. Dirty air filters can cause issues such as restricted airflow and reducing the evaporator coil’s ability to absorb heat. As a result, this can make your AC system work harder to cool your home and can raise your energy consumption.

GRILLS AND REGISTERS

Inspect the grills and registers in your home to see if they need cleaning. Dirt, dust and pet hair can build up and hinder airflow through these airways. Also, open and shut registers to ensure that they work and check to see that furniture is not covering the vents. Never leave your vents closed to try and force air into other rooms of the house. This will cause your coil to freeze up and your system to shut down. 

DUCTWORK

Check exposed ductwork in places such as the basement or attic to see if there are any problem spots such as gaps or disconnected areas. You should also look for:

  • Peeling duct tape and loose fittings around seams
  • Dirt streaks that indicate escaping air
  • Dents in metal
  • Collapsed or torn sections of flex ducts

THERMOSTAT

Check the thermostat to make sure that it is operating properly in both the heating and cooling functions. Make sure to check for dust and dirt by removing the thermostat cover (if there is one) and discard particles by using a cotton swab. Also, if your thermostat is battery operated, try installing a fresh battery. Even if the display is lit, a weak battery may be a culprit.

OUTDOOR AIR CONDITIONER UNIT

Inspect your air conditioner to see if it is being blocked by vines, shrubs or leaves. If the unit is blocked or covered, it can cause the compressor to stop running, become loud or overheat.  Also, check to see that the condenser unit fins are straight and undamaged. If you notice the fan blades are damaged, call an expert to replace the blade.
