The HVAC unit in your home is a vital piece of equipment that you depend upon throughout the year to stay warm or cool. Without
proper AC maintenance, your HVAC system can encounter problems. Here are some steps you can take as a homeowner to
ensure your AC unit functions properly.
Outdoor AC Maintenance
Start the self-maintenance process by cleaning your outdoor condensing unit. Vegetation overgrowth takes off when Spring comes around. During the Winter months, wind can blow debris into and on the unit.
Clear all vegetation and debris away from the condensing unit to prepare for a thorough cleaning. You may find that the fins on the condensing unit are clogged with dirt and dust.
Clear the debris by spraying with a gentle stream from your hose into the fins. Do not use high pressure as this can damage the fins.
Indoor AC Maintenance
Keeping the indoor air handling unit in working condition is also vital to the efficiency of your HVAC system. The primary intake of air occurs here as it travels through the air blower and past the evaporator coils. That means that many different kinds of air particulates make their way through the system every day.
Thermostat Check – Blower Fan
Regularly check the thermostat for proper function. If the unit uses batteries, replace them on a consistent basis. Turn on the fan switch to ensure that the blower fan is operating properly.
If the blower fan seems to be struggling to pull air in then perform the following checks:
- Check the circuit breakers/fuse for the unit – reset as necessary
If at all possible clean the evaporator coils. They are located in the plenum above the air handling unit. Some installs have a small access port. However, do not be alarmed if the unit is sealed. In that case, contact us so that the plenum can be opened and resealed properly.
Evaporator coils can become clogged with all kinds of dust, dirt, and other particulates that cross over them with time. It is important that they are thoroughly cleaned to keep your system working in the most efficient manner possible.
Condensate Drain or Pump
Make sure that there is not a buildup of water on the floor as the condensate drain or pump might be clogged. If you have a pump and it's not working, your furance won't work neither due to the safety switch so you don't flood your basement.
Your system air filter is by far one of the most critical elements of your HVAC system and the easiest to keep maintained. But you may be surprised by how many people will neglect this easy AC maintenance step.
Replace the air filter on a monthly basis and never let it go more than three months. A restricted air flow will create unnecessary strain in your HVAC system.
