Frozen coils are never good because it means that the refrigerant is leaking. There are a few reasons why this is happening, and we can help!
Have you noticed that your home doesn’t get cool enough no matter how low you turn down your AC? If this describes your case, it’s not global warming; it’s your AC coils. Your AC coils hold the refrigerant, a unique liquid responsible for cooling your home. The AC coils absorb heat from inside the house, dispel it outside, and repeat the process until your home is sufficiently cool.

My AC unit was located on the ground in a very undesirable area; in the direct path of my neighbor’s downspout.

Extremely satisfied with their work!

I called on December 25th at midnight and started leaving a message and Thomas Hoffman the owner called me back almost immediately. He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time. He fixed my problem and while he was there I decided to get an estimate for a new furnace and air conditioning unit. The price was very reasonable and the installers one of them being his son were both very professional very courteous, polite, arrived on time and finished the same day. I enjoy knowing that I now have the support of Thomas Hoffman heating and air conditioning along with the peace of mind that comes with owning a Trane. Nothing stops a Trane.Albert Koesterer

Giovanni was good…. This is reason we ask for him
Response from the owner: Thanks so much!
Zac and Giovanni are always extremely polite, considerate and professional. We are thrilled to have the new A/C unit. Our unit was 18 years old and stopped working in the thick of 100 degree weather. Tom (the owner) came over within an hour (after hours) and bought us time by changing out some parts until we could have the new one installed. We’re very happy with Thomas Hoffmann A/C and Heating!
Response from the owner: Katie, we're delighted that Zac, Giovanni, and Tom were able to assist you promptly and effectively during the heatwave. Thank you for choosing Thomas Hoffmann A/C and Heating!
Honest takes his time to listen and help you without charging Arm and a leg
Response from the owner: Thank you so much for your kind words, Carrie! We truly appreciate your feedback.
Couldn't be happier with our experience. Our AC stopped working after typical hours and they were the only "24/7" HVAC service who was able to come out same day. Not only were they fast, but they identified and fixed the problem immediately and did some preventative maintenance (and showed me how to do it) to prevent it from happening again. Will absolutely use them again in the future.
Response from the owner: We're so glad to hear about your positive experience, Hannah White! Thank you for choosing us and we look forward to helping you again in the future.
Great service! Prompt, polite and got the job done quickly.
Response from the owner: We're so happy to hear that you had a great experience with us! Thank you for your kind words.
Thomas Hoffman personally quoted the job at a fair price and they did a quality install! I would highly recommend them!
Response from the owner: Thank you for recommending us, Joe! We appreciate your feedback and are glad you were satisfied with our service!
Came same day and fixed the problem.
Response from the owner: Thank you for your feedback! Glad we could help you out the same day.
Caught in a bind one evening (no AC), I called for an appointment to get mine repaired. They came out the next morning, one half hour early! Within 30 minutes we back up and running!! Thank you, Thomas Hoffman. You are my guys!
Response from the owner: Thank you for choosing us, Sue! We're glad we could help you out quickly and get your AC up and running smoothly again! Thomas Hoffman and the team appreciate your kind words!
Blower went out on a Sunday. They answered my call, got me in, replaced blower, very easy!
Response from the owner: We're so glad we could assist you with your blower on a Sunday! Thank you for sharing your experience with us.
Thomas is amazing and came over in only a couple hours and fixed my ac! True life saver 🙏🏼
Response from the owner: Thank you for sharing your experience with Thomas! We're glad to hear he was able to help you out quickly and efficiently. 👍
Fantastic experience! Our AC went out on a scorching Saturday evening. I wasn’t actually expecting anybody to get out that night, but when calling - I immediately got an answer, was on the schedule in 5 minutes, and Thomas showed up an hour later. He was honest, professional, and educational. Most importantly, I didn’t feel like he was cutting corners or trying to get in and out… a welcome contrast from most services these days. 6 stars out of 5, highly recommend.
Response from the owner: Thank you for sharing your experience, Andrew! We're so glad to hear that Thomas provided such honest and professional service for your AC needs. We truly appreciate your recommendation and look forward to serving you again in the future.
6 Common Causes
Frozen coils are never good news because it means the refrigerant is leaking. There are many reasons why your AC coils are frozen. But, regardless of the reasons, the consequences always remain the same; a highly inefficient AC.
Here are a few reasons for frozen AC coils. That way, you can take the necessary measures to keep your AC oils from freezing. So, without wasting much time, let’s dive straight into it.
- Dirty Air Filters – You must replace your air filters at least every three months. Dirty air filters are among the leading causes of frozen AC coils. Remember, your AC needs a steady supply of air to function correctly. Dirt and debris that clogs the filters may hinder sufficient airflow. This hinders enough air from getting to the AC coils. Unfortunately, this means the coils get too cold and eventually freeze.
- The AC Fans Are Broken or Don’t Work – Fans are a crucial component of your AC unit. The fans are what push the air towards the coil for cooling. However, when the fans break, they cannot push the air to the coils. This means the coils don’t get sufficient air, so they freeze.
- The AC Coils Are Dirty – Apart from dirty filters, dirty evaporator coils are also a serious problem. When dust and debris accumulate around the coils, they hinder their ability to dispel and absorb heat from the environment. This leads to humidity condensation, which eventually freezes on the coils.
- It’s Too Cold Outside – There are instances when the temperature outside is too cold. In such cases, the air won’t have sufficient heat for the coils to absorb and keep them from freezing. This is one cause that is beyond your control.
- The Drain-pipe is Clogged – It’s normal for condensation to form on the AC coils. This condensation drains through the drainpipe to the outside. The condensation will have nowhere to go if the drain pipes are clogged. In this case, the condensation clings to the AC coils and freezes.
- Refrigerant Problems – Ensure your AC coils have enough refrigerant to function correctly. Not having enough refrigerant in the coils will make your AC overwork. When this happens, the condensation on the coils is likely to freeze instead of draining through the drainpipe.
Don’t Let Your Coils Freeze
Now that you know why your coils freeze, you must ensure that yours don’t. That’s unless you want to contend with an inefficient AC and astronomical energy bills. Contact Thomas Hoffmann Air Conditioning & Heating today, and we’ll help you unfreeze your AC coils.
