All you need to do is take the old filters out, go with them at your local hardware store and buy exactly the same model. This is the most important part of the whole process – to purchase the right filters. Also, keep in mind that sometimes you don’t need to replace the filters. A simple cleaning might do the trick, especially if they are not extremely dirty.

Evaporator Coil.
Most HVAC systems have two main components, the inside unit and the outside one. The outside unit contains an evaporator coil which looks similar to a car radiator. Due to the fact that is located outside the house, the evaporator coil often tends to get clogged with dirt and debris. When this happens, the entire heating and cooling system becomes inefficient. Luckily, the fix is simple. Using a paint brush, clean all the dirt and debris inside your evaporator coil.

Blown Fuses.
In order to protect the motor from overheating and eventually fail, the HVAC system is equipped with a fuse box. The box is located on the outside unit. If your system doesn’t receive power, it means one of the fuses may have blown out. What you can do is open the box and check for the blown fuse. However, we highly recommend you hire a specialist for this task. Working with electrical components is extremely dangerous, so don’t risk it.
