Without taking you to HVAC school, I will try to explain why having your outdoor unit regularly cleaned helps prolong the life of your unit and lowers your electric bill.
Freon is a heat absorbing liquid. It goes into your house, removes the heat from your house, takes it outside, and gets rid of it by the fan on top of the outdoor unit. The fan pulls outdoor air through the outdoor coil and removes the heat from the Freon; this is why during the summer the outdoor fan blows hot air if you put your hand over the fan. If the outdoor coils are dirty, air can’t get through the coil and remove the heat properly. This causes heated Freon to go back into the house and doesn’t cool your house effectively. This makes your air conditioner run longer which puts more strain on your compressor and fan outside; which in turn causes your electric bill to go higher. A good maintenance plan can help your unit not only stay clean and run at peak efficiency, but will also help your unit last longer.
Airflow is key to having a unit run efficiently. The best way to ensure that you have proper airflow is to have a professional maintenance plan by a company you can trust that has your best interest at heart.
