Why is my AC not Cooling?

AC not cooling - CampbellCare

When the weather gets hot, it’s advantageous to have a cool home to hide away after a long day. There’s nothing worse than discovering your air conditioning system isn’t working up to par when you need it most. Save yourself a sleepless night by installing an AC unit before you need it. Otherwise, you’ll be asking yourself, ‘why is my AC not cooling’ while you get drenched in the summer heat.

If you’re running into problems with your AC not cooling effectively, there may be several causes to consider:

Your thermostat may be set incorrectly

Before you try to get to the possible reasons behind your AC not cooling, check your thermostat settings. If your unit is set to “cool”, switch the setting to heat or fan, then switch it back to cooling. Wait a few minutes after the system kicks in, and hope that cool air comes rushing back.

Check your return-air filter

This is especially important if you haven’t thought about your AC since last summer. It is possible that your return-air filters may be clogged, therefore not allowing the cold air to blow through. Simply remove your return-air filter, and if it is too dense with debris – it’s time for a replacement.

Your outdoor unit needs cleaning

Your condenser draws all the air inside before your system cools it and works it through to your home. If this unit is too dirty and clogged to collect the air, that is likely where your problem lies. To give your outdoor condenser a refresh, simply gently remove any debris and hose it down with your garden hose. Be careful that your stream isn’t too strong as the condenser fins are delicate.

Potential refrigerant leak

This is the piece that is responsible for absorbing the heat from your home’s air. Without this working properly, you won’t be able to feel any cool air coming through into your space. Other signs that may indicate this is the problem are:

  • having a frozen refrigerant line on your outdoor unit
  • feeling warm air blowing from your AC vents
  • hearing a hissing sound coming near the AC unit

A refrigerant leak doesn’t have an easy fix, and you’ll need to call in your local HVAC professional to get the cool air back into your home.
