Why Does My Air Conditioner Take So Long to Cool?

Woman and Fan

There’s nothing quite like another beautiful sunny day—besides maybe an air conditioned home. You feel lucky to live in such a beautiful state, but even luckier to have an air conditioner you can turn to when outside temperatures get a little too high. That’s what makes it all the more frustrating when your air conditioner won’t run the way you want it to.

Is your central AC system taking way too long to cool your home? It’s a common problem, but we may have some good news. In some cases, there’s an easy fix. And sometimes, homeowners just need to change the way they think about their air conditioners and the way they use their thermostats. For any other AC repair, we’re here for you!

Reason #1: It’s Hot!

Here’s the deal: if it’s hot outside, it’s going to take longer for your air conditioner to cool down your home. It’s something you may just have to deal with, as it likely doesn’t mean that anything is wrong with your air conditioner. However, there are things you can do to ease your patience.

If you don’t already have a programmable thermostat, it’s time for an upgrade. Use it to keep temperatures consistent for much of the day. To save energy, you can schedule it to raise the temperature for the hours you are away, and then to start up again a half-hour before you get home. That way, you don’t have to wait so long for the house to cool down!

Reason #2: Your Filter Is Dirty

It’s possible that you are dealing with a fairly simple problem to solve. A dirty air filter will stop air from moving through the AC system with ease. It’s all clogged up with enough dust and grime to prevent the amount of airflow you need to stay cool! You should be changing your air filter every month or two anyway, so try this step before calling a technician if cooling times seem to be unusually low.

Reason #3: Environmental Factors in the Home

There’s also the chance that your home is contributing to inefficiency, making it more difficult for your air conditioner to cool the rooms. For example, if you have air leaks around the home—cracks around doors and windows or leaks through exterior pipes—your air conditioner will have to work a lot harder. Sealing air leaks and adding insulation to the home can help to keep the heat from getting in.

Reason #4: These Common AC Repair Needs3

Finally, your air conditioner may need a repair that only a trained air conditioning technician can really handle with confidence. There are a few reasons your air conditioner may be taking far too long to cool your home.

  • Low levels of refrigerant, indicating a leak.
  • Problems with the fan or blower motor.
  • Dirt coating the coils.
  • Electrical troubles.

In any case, be sure to call a local contractor to repair the problem before it becomes any more severe.
