Winters in Texas are not given enough credit. These months get pretty chilly, and you rely on your heating system quite often. But how about your air conditioner? It can freeze up during these cold months, so you need to maintain it even if you aren’t using it. Ellis Air Conditioning and Heating has come up with 4 ways to stop your air conditioner from freezing up. And if your HVAC system needs repairs or replacements, get in touch with us right away.
The Defrost System
It is expected that your air conditioner will freeze occasionally throughout the winter. That’s why it undergoes a built-in defrost cycle every hour, half-hour, or 90 minutes. In order to keep your system from freezing, the unit blows cool air inside and releases hot air outside. However, the defrost system is not bulletproof. The cold temperature and a lack of maintenance can cause your AC unit to freeze. Here are a couple of things to keep in mind when maintaining your HVAC.
Check and Change Your Air Filter
You need good airflow in order to keep your air conditioner from freezing up. A dirty air filter will clog up the flow of the air. This prevents sufficient airflow through the return air duct. If there isn’t enough air flowing through the evaporator coil, it will develop an ice layer. Therefore, we recommend that you change the air filter at least every three months.
Check Your Vents
Try not to block your vents with furniture. This allows air to easily pass through. Make sure that the vents are open and not blocked. Although you can save money by closing your vents to prevent the air from cooling rooms you aren’t using, having too many of them closed can backfire. Restricting too much airflow can cause your air conditioner system to freeze up. That’s why you shouldn’t close more than two or three vents.
Faulty Blower Fan
Your blower fan needs to be in good condition to prevent your air conditioner from freezing up. A faulty blower fan doesn’t generate enough airflow to keep the coil from freezing. The best thing to do is to get a professional HVAC inspection. Ellis Air Conditioning and Heating is only a call away. Our technicians will inspect your blower fan and check the age, overall wear condition, rotational direction, rotation speed, and power output.
Do NOT Pour Hot Water On Unit
Have you ever tried pouring hot water on your car windows in order to defrost them? Although it works magic for your car, you don’t want to pour hot water on your air conditioner to defrost it quickly. This will do more harm than good to your HVAC.
