Why Does My A/C Unit Keep Freezing?

Question from user Topher1326 at AirConditioners at reddit.


Answer:


If your A/C unit keeps freezing, there are a few possible reasons why this may be happening:


Dirty air filter: A dirty air filter can restrict airflow over the evaporator coil, causing it to freeze.


Check the air filter and replace it if it's dirty.


Low refrigerant levels: If your A/C unit is low on refrigerant, it can cause the evaporator coil to freeze.


This is often a sign of a leak, and a professional technician should be called to repair the leak and recharge the refrigerant.


Thermostat issues: If your thermostat is not working properly, it may be causing your A/C unit to run too long, which can result in the evaporator coil freezing.


Check the thermostat settings and make sure it's functioning properly.


Dirty evaporator coil: If the evaporator coil is dirty or clogged, it can restrict airflow and cause the coil to freeze.


A professional technician can clean the coil and restore proper airflow.


Fan problems: If the fan motor or blades are not working properly, it can cause the evaporator coil to freeze.


A technician can inspect the fan and repair or replace any damaged parts.


If you've tried these troubleshooting steps and your A/C unit is still freezing up, it's best to call a professional technician to diagnose and repair the problem.

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !

Great customer service. Responsive and professional. I would highly recommend Twintech, I used them previously for repair service and a new air conditioner- very satisfied.

by dianeramsden on Twintech Heating and Cooling

Our air conditioner failed. Made a call and within 15 min a technician was at our door.
The issue was fixed and many suggestions were provided.
Thanks to Mitch. Great service !

by Kazuko on Twintech Heating and Cooling

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

My furnace broke down last month. The team was quick to respond, courteous, professional and mindful of COVID-19 concerns. I highly recommend them if you are considering replacing or servicing your HVAC equipment.

I was very happy with the installation and price. I would definitely recommend. Thank you Twintech.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Robert Rogers on Twintech Heating and Cooling

Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.

by Robert Mizuno on Twintech Heating and Cooling

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
