There are several possible reasons why your air conditioner (AC) may be freezing up. Here are some common causes:
-
Dirty or clogged air filters: When the air filters are dirty or clogged, it restricts the airflow over the evaporator coils. This can lead to a drop in temperature and cause the coils to freeze.
-
Low refrigerant levels: Refrigerant is responsible for absorbing heat from the air. If your AC has low refrigerant levels, it can cause the evaporator coils to become excessively cold and freeze up.
-
Blocked or closed-off vents: Blocked or closed vents can restrict the airflow, causing the evaporator coils to get too cold and freeze.
-
Faulty blower motor or fan: If the blower motor or fan is not functioning properly, it can result in inadequate airflow over the evaporator coils, leading to freezing.
-
Thermostat issues: A malfunctioning thermostat can cause the AC to run continuously or at lower temperatures than necessary, leading to freezing.
-
Problems with the condenser unit: Issues with the condenser unit, such as a dirty or blocked condenser coil or a malfunctioning fan, can disrupt the heat transfer process and cause freezing.
-
Incorrect AC sizing: If your AC unit is too large for the space it is cooling, it may cycle on and off too frequently, preventing the coils from properly dehumidifying and causing them to freeze.
If your AC is freezing up, it is advisable to turn off the system and allow it to thaw completely before attempting any troubleshooting. It's recommended to contact a professional HVAC technician to diagnose and fix the underlying issue, as they have the expertise and tools to handle air conditioning problems safely and effectively.

On one of the coldest days of winter, our furnace stopped working. Our regular furnace company came and told us we had a CO2 leak and shut us off. Their quote for a new furnace was way too high and they couldn't even install it on the same day. TwinTech was recommended to us by a friend. We called and spoke to Dave who was very nice and knowledgeable. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price. I would recommend TwinTech with no hesitation at all.

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldnÂ’t believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.
