What to do when your Air Conditioning is taking a break

Home Inspector with National Property Inspections

If your home's inside temperature is feeling more like the warm outside temperature, it could be a problem with the air conditioning system. What should you do when there is no air conditioning working in your home?

  • Check the thermostat. Is it set to "cooling" or "AC?" Is it set lower than the room temperature indicated on the dial or screen? If it's a digital thermostat, is the battery dead?
  • Check the on/off switch on the side of the furnace or near the furnace. The furnace distributes air for the air conditioner and must be on.
  • Is the disconnect switch outside at the AC unit switched off, disconnect pulled or the fuse blown?
  • Is the main breaker fuse for the air conditioner off? Reset the breaker or replace the fuse.
  • Check for a broken belt or clogged air filter on the furnace
  • Is the coil above the furnace iced up?
  • Is the exterior coil dirty or blocked by plants?
  • It is always important to call a qualified service technician when you have questions or concerns and don't feel comfortable performing the checks above yourself

Great tips. We run into a lot of blown fuses when fixing thermostats. We wrote a blog post about all the different types of thermostats a while back. Do you have a blog outside of Activerain? We'd be interested in linking with you.
