Why Is My Air Conditioner Freezing Up? 

Why Is My Air Conditioner Freezing Up? 

One of the most common problems that people have with their central air conditioners is that they freeze up. This problem can be avoided, and should not happen to any household provided if you follow a few simple steps.

First, make sure your thermostat is set correctly on your unit. You want it to be in the "cool" position, but not too low or too high for your specific needs. The ideal temperature range is between 20-24 degrees Celsius.

Secondly, make sure there are no leaks or gaps around the outdoor unit - these can cause water to get inside and freeze up the system. Finally, as a general rule of thumb, keep your home at least a few degrees cooler than your thermostat setting. This will help prevent the system from working too hard and potentially freezing up sooner. 

Third, if you live in a colder climate or have an older air conditioner that is less efficient, it may be best to turn off the unit during extreme cold spells. You should wait until the weather begins to heat back up.

Last but not least, get regular maintenance on your unit by a professional technician from A-Plus Quality, HVAC services in the Greater Toronto Area, who can check for leaks and make sure all other components are running smoothly. If everything checks out and there's still some concern about why your central AC keeps freezing over, consider upgrading to a more up-to-date air conditioner. You should be on the search for equipment with high-efficiency ratings. Contact our team at A-Plus Quality to discuss installing a new air conditioner in the Greater Toronto Area, or surrounding cities! 

By following these few tips, you can keep your central air conditioner from freezing up and save time and money on potentially costly repairs.

FAQ

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • Furnace is blowing cold air in Winter?

    This can be due to Ignition lockout, sometimes could be resolved by resetting the power  and if this does not resolve the issue you should contact a certified gas technician from A-Plus Quality to get this problem resolved!

  • Why is there ice building up on the copper pipes?

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
