Keeping a home comfortable is an ongoing struggle for a lot of people. There are a number of factors that go into having a comfortable home and among the most important is an efficient HVAC unit. Over time, the HVAC unit in a home will begin to show signs of wear and will have to be seen about by a professionals. Among the most common occurrences for an older HVAC unit is freezing up. When a unit freezes up, the homeowner will have to take the time to figure out what is going on. The following are a few reasons why a unit is freezing up and what needs to be done to fix it.
Low Refrigerant Levels
One of the most common causes of a unit freezing up is not having enough refrigerant. There are a number of things that can cause the refrigerant to leak out and finding the root cause is the only way to get this issue fixed. By calling a professional, you will be able to figure out why the refrigerant is leaking out and what they can do to stop this problem from occurring.
Lack of Proper Air Flow
Another very common reason that a unit will freeze up is a lack of proper air flow. The air filter in your unit is very important and changing it on a regular basis should be a top priority. Neglecting to change the filter on a regular basis will usually lead to it clogging up with dust and other allergens. The longer the unit goes without the proper air flow, the harder it will be to get the right performance out of it. The changing of the air filter is something that a homeowner can handle on their own.
A Broken Thermostat
Yet another very important part of a HVAC unit is the thermostat. This piece is used to get the temperature of the home down to where it should be. Over time, the thermostat you have will begin to show signs of wear and will have to be replaced. In most cases, a homeowner will be able to tell that their thermostat is not working properly due to the unit freezing up. As soon as this issue is detected, the homeowner will have to call in a professional to take a look at it and perform air conditioner repair.
