Your home air conditioner has one job—to cool your home—so when it begins to fail it’s one task, it is understandable for homeowners to get frustrated. There are many reasons why your air conditioner may be failing to preform it’s one and only task. Here are those reasons and how you can fix them so that you can get the most of your air conditioner when you need it

Open/ Closed Airways
Be sure that you close all your windows and doors and open all of your vents so that cool air can stop or flow appropriately. It is often the smallest and silliest things that get overlooked. Before you get professional help, check on these fixable issues.

A Faulty Thermostat
The first thing you should check when your air conditioner isn’t working is your thermostat. Be sure that it is set to “ON” and “COOL”. If you hear your air conditioner running after ensuring these settings, there may be a problem with the electrical wiring of your thermostat. Get a professional to deal with this issue.

A Tripped Breaker
Your AC runs on electricity so if something happens to the breaker, it will definitely affect your AC’s working conditions. Flip the breakers for your air conditioner on and off again and see if it makes a difference. If not, call a professional to help fix the issue.

A Clogged Air Filter
An air filter clogged with dirt and debris creates a block for cool air to enter into your home through your ductwork. Check your air filter monthly and remove anything that can be causing the airflow issue. Also be sure to change your filter every 3 months or more frequently if you have hairy pets, allergies, or lots of people living in your home.

A Dirty Outdoor Unit
AC’s require clear pathways to function efficiently. If your outdoor unit is coated in dirt and debris, this will cause blocks to the pathways and an ineffective AC unit. Clean up your outdoor unit and remove all dirt and debris. We highly recommend regularly washing with soap and water. Next, try tidying up the landscape around the unit to keep branches, bushes, and other things away from the unit.

Other reasons as to why your air conditioner may not be working include mechanical issues, leaking refrigerant, poor installation, or leaking ductwork. If you have addressed each of these issues and your AC still does not work, it may just be time to get a new one.
