What Should I Do If My Air Conditioner Freezes Up?

Typically, air conditioners freeze up when airflow is blocked, refrigerant levels are low, or there’s a mechanical failure. If your AC has ice on it, turn it off and let it defrost. Next, change the thermostat setting to “Fan” only—this helps dry the coils. Wait before setting the thermostat back to “Cool” and seeing if the AC is working again. While you wait, check if your air filter is dirty or if the unit itself is covered in debris.

How Do I Know If I Need to Replace My AC?

Your air conditioner may need replacing if it:

  • Is 15 or more years old
  • Causes your energy bills to skyrocket
  • Breaks down and needs repairs often
  • Doesn’t keep your home as cool as it used to
  • Uses R-22 refrigerant—this refrigerant is no longer manufactured, so a recharge may now cost up to 10 times more and not be worth the price

Why Isn’t My Air Conditioner Cooling My Home?

If your AC isn’t cooling properly, it’s likely there’s a mechanical failure that requires professional repair. When this happens, call the team at Air Tech Heating right away—we’ll diagnose the problem and recommend a repair before starting any work, or let you know if it’s time for a new cooling system.

Do I Need Air Conditioner Maintenance?

Absolutely. Maintenance is the only way to keep your system running safely and efficiently year after year. It gives our experts a chance to inspect and clean your system, as well as find and fix any existing issues before they get worse. Annual service can even lower energy bills and help your system last as long as possible.

How Long Do Air Conditioners Last?

An AC’s lifespan typically lasts about 15 years, though some can run safely and reliably for 20 years or longer with routine maintenance.

Michael Nanna

Of course our old air conditioning unit stopped working on one of the hottest days so far this summer. Air Tech Heating immediately jumped thru hoops to replace our air conditioner with a new Bryant unit. They are so wonderful to work with and are a top tier company with the best products. Are new unit is so quiet and so much more efficient!! Can’t wait to see my next power bill. Give them a try. You won’t regret it.

Jon Jahn serviced our furnace and changed the needed filter. He provided excellent service and was very professional. I would definitely recommend Air Tech Heating to anyone needing a new heating/air conditioner or service.

Sue Schommer

AirTech was very quick to take care of us. Jon was very courteous and knowledgeable and took the time to explain the problem to us. We had an excellent experience with AirTech and will continue to call on them for any future needs, and highly recommend them to others.

Lori Borth

I have been using Air Tech Heating for about 10yrs. The office personnel are always friendly and helpful. The technicians are always professional, polite and arrive within the timeframe scheduled. I am so confident in this company that I am purchasing a new furnace from them. I highly recommend this company.

Tammy Wiese

Called at night after hours. It was not an emergency for us. Was told they would call in morning – received a call as promised and was scheduled during a specific time – technician had problems with other calls and was later than expected time – office and technician apologized for the inconvenience- very respectful of our time – always provide best service

Steve Kin

I am so happy with the work and the installers. They were here when they said, promptly got working on taking out my 36 year old furnace, all of them were kind and courteous as well. Once the new furnace was installed they showed me how to operate my new thermostat and how the furnace itself worked. I am very pleased with how it is heating my house. I would recommend them to anyone.

Colonel Joseph

I have been getting my AC and Heat serviced every year by Air Tech Heating for a few years now and could not be more happy. My furnace had a major issue several times and they never tried to upsell me into getting a new one. They just offered it as an option. I wish I had taken them up on this sooner but it took until this year to replace my system. They arrived on time the morning of 11/27 and did an excellent job on the install and clean up. They took the time to answer all my questions and left my house the same or better then when they arrived. Very trustworthy, respectful and professional crew.
Thank you Air Tech Heating and see you again during my next PM service.
