  • If you have an old thermostat with no batteries, make sure you hear the click when you turn it on. If you listen and there is no click, you may need a new.
  • If you have a digital thermostat, you should replace the batteries
  • If you replace the batteries or can’t install new ones and the thermostat is blank, check the power or replace the thermostat.

  • Check the ductwork in the attic or the basement.
  • Having clogged ductwork or broken ductwork can cause a lot of issues.
  • You can fix small tears with duct tape.

  • Make sure you have power to the furnace, without power to the furnace you won’t have air blowing throughout your home or office.
  • Without the power to the furnace, your air conditioning will not receive the signal to turn on.
  • Make sure your outlet has power, you can check this by plugging in a small electronic device like a phone charger.
  • If there is no power coming out of your outlet reset your breakers at the power panel and check for power again.

  • Use the thermostat to turn on the air conditioning system
  • Go to the air conditioning unit and see if it turns on.
  • If it doesn’t turn on, check the fuses.
  • The fuses are found on the wall inside a 4″x10″ box usually.
  • You can replace the fuses for less than $10.

  • If you replaced the fuses at the condenser,  you would check the main power panel.
  • Find the A/C breaker inside the main power panel.
  • If it’s not listed, most A/C unit use more then 30 AMPS breakers.
  • Reset the breaker by turning it off and on.

  • If the unit is turning on but not cooling try washing down the condenser.
  • A dirty condenser can cause significant problems to the air conditioning system.
  • Turn the unit off first.
  • Get the water hose and rinse off the entire unit except for the electrical.
  • Turn the unit back on and see if it makes a difference.
