HVAC units are built sturdy enough to last for many years, but a diligent maintenance will keep them at optimum performance. Knowing the most common problems and HVAC repairs will help you understand how to keep your HVAC operating more efficiently longer.
The Common HVAC Repairs
The fuse is what keeps the unit’s compressor or motor from overheating. When the unit stops working, the technician checks this first.
Filters actually need to be replaced or cleaned about every 2 months if your want your unit to be operating smoothly. A dirty filter reduces air flow which causes the unit to freeze.
Refrigerant keeps the air cool, and hence, when there are leaks, the unit will not keep a comfortably cool temperature. This also will lead to another problem, the compressor.
The compressor is regarded as the heart of the unit, and if the refrigerant levels are low, the compressor will eventually stop working.
A drain line removes the condensation building up in the condenser coil. If the drain line collects dirt, there will be a water build up in the drain pan and can cause water damage to the unit.
Condenser and Evaporator Coils
Coils remove heat from the air. Check the coils and keep it clean. Dirty coils reduce the cooling power of your air conditioning system causing your AC unit to work harder. If the unit is off, you can clean it with a water hose. If you are uncomfortable spraying out the coils then it is best to let an HVAC technician clean it for you.
A capacitor jumpstarts your HVAC’s motor and keeps it running smoothly and at a consistent speed. This, however, can burn up and hence, will not start the motor of the unit. When this happens, only an HVAC professional should tackle this due to the high risk of electrocution.
