“Does My Air Conditioner Need More Freon?” [FAQ]

Checking Freon Is your air conditioner not cooling your home properly? Most homeowners usually think, “My air conditioner must need more Freon!”

Well, it may. But don’t jump the gun. Your problem may be caused by something simple you can actually fix.

Fixing these simple problems can save you the cost of a service visit.

Do these 3 troubleshooting tasks before calling an AC service person for help.

1) Check your thermostat settings

Make sure that your thermostat is not:

  1. Set too high
  2. Set on heat by accident

2) Check the air filter

Is the air coming out of your supply vents very weak? You may have a dirty air filter.

Why would that prevent your AC from cooling your home?

Well, your air conditioner doesn’t just create cold air; it recycles the warm air from your home and cools it off.

But before the air is cooled by the AC, it has to go through the air filter. If it’s dirty, the air has difficulty passing through to be recycled into your home.

Change the air filter if it’s dirty.

See how to change your air filter.

3) Clean the outside unit

Your AC is most likely a split system, meaning there is an inside and outside unit. The outside unit’s job is to disperse heat from the Freon so it can cool down and absorbs more heat from your home’s air.

But if the unit is dirty or smothered by a bush, it has trouble dispersing the heat from the Freon, meaning your air conditioner will have trouble cooling your home.

The outside unit should be cleaned once a year. And many AC service company will clean it as part of an annual maintenance visit.

Is your AC still not cooling well?

If your AC still isn’t cooling your home well, then it may need more Freon or there is another issue that’s causing the problem.

If you’re low on Freon that means there’s also a refrigerant leak that needs repairing.

If you hear a hissing or bubbling noise coming from the AC, that means the refrigerant leak is very large and needs repairing ASAP.

  • Francis from Nicholson Plumbing and Heating was excellent. He was here to evaluate HVAC in our home. He was very patient and answered all my questions. He is also polite and easy to communicate with him. He explained technical concepts to me in layperson terms!

  • Nicholson offered what is possibly the best customer service I have dealt with in a home repair situation.  I called them because I was looking to replace my very old furnace.  They came out to do an initial estimate, and then came back when I had some further questions about my options.  After installing the furnace, they ran into some problems with my air ducts.  This happened on a Friday, and the problem was fixed by Monday afternoon.  In addition to their excellent service, they did quality work at a fair price.  I would recommend them to anyone looking for an HVAC company in the Framingham area!

  • Recently used these guys because my HVAC unit AC wasn’t working (first hot day of summer).  Showed up on time, wore booties, fixed the unit.  During the visit we talked about how my unit was having problems in the winter – which was resulting in NSTAR service calls of maybe 3-4 times per season (I am on a service plan with them).   He was the first guy to tell me WHY the problem was happening, and HOW to fix it.  I find it strange that all of the NSTAR guys etc. no one took time to point out how to fix the source of the problem…Very professional, smart.  I would use them again, and plan to for the fix on my heating unit!
