Tips To Sustain Optimal Efficiency

As you may know, an AC will last on average around 10 years if you don’t invest time into thorough maintenance. If you take care of it regularly, some people have their models for more than 10. Don’t worry, you don’t have to do a lot of labor work. In fact, if you clean the filter when you are supposed to, it will last with ease for at least 10 years. As long as you follow the tips below, you will find that your purchase will turn into an investment.

Check The Coil

Whenever the time gets cooler, you should wash the condenser coil on the outside unit. You should do this at least once a year as it ensures the AC running at peak efficiency. A dirty condenser coil runs hotter and is less efficient. You can tell if it’s running low by:

  • Check the copper tube connecting the outside unit to the inside unit
  • If it’s clogged, the unit is heated up
  • Call for professional service to tell you if the unit is low on refrigerant
When You’re Not At Home

You don’t have to necessarily turn it off completely when you go on vacation. This is because when you will arrive home, it will work much harder to cool the house when you turn it back on. As well as, it will take a long time to cool down the whole room. You should remember:

  • Plants, pets, and appliances will suffer if you don’t set a timer
  • Set the temperature 5 to 10 degrees higher than normal
  • It will take less than 1-hour to cool down the room when you come back
Don’t Obsess Over The Thermostat

We recommend that you leave the thermostat at 78-degrees Fahrenheit. Some people sneak in and try to turn the heat down. What these people don’t understand is the fact that you don’t have to turn it lower to cool the house down faster. The AC will cool down the room at the same rate no matter where it’s set. Adjusting the temperature to 70-degrees will not help your house get to 78 degrees any faster than leaving it at 78-degrees.
