5 Reasons Your HVAC Unit Keeps Freezing Up

If your heating and cooling system keeps freezing up, you need to contact a heating and air condition service in Irving, TX immediately. Even though an experienced and certified HVAC technician can inspect your heating and cooling unit to tell you exactly what is causing it to freeze up, knowing the main reasons behind it will be beneficial for you:

1.   The Air Filters Are Dirty

Dirty air filters can cause your air conditioning unit to freeze up. When your air filters become dirty, it restricts air flow, preventing it from entering your HVAC unit. This results in the condensate collecting on the coils, causing your HVAC unit to freeze up. You can replace the air filter, but if the problem continues, you will need to contact an HVAC technician to perform a heating and air condition service in Irving, TX.You do not want to leave it up to chances, but take measures to protect your air conditioning unit, as soon as you identify the problem.

2.   You Have a Broken or Damaged Fan

Your heating and cooling unit’s fan circulates the cold air produced by your system all around your home. A broken or damaged fan collects the cool air and freezes it. Check to see if your HVAC unit is releasing air out of the vents. If it is not, you have a broken or damaged fan for which you need to contact your local HVAC company for heating and air condition service in Irving, TX.

3.   There is a Refrigerant Leak

If there is a refrigerant leak, your heating and cooling unit will naturally freeze up. A refrigerant leak causes the pressure within your HVAC unit to change. This results in the warm air in your home to move across the heating and cooling coils, but it does not cool it down and move it, but turns it into ice.

You will need to get in touch with your HVAC company for heating and air condition service in Irving, TX. If you do not fix a refrigerant leak, you will find yourself replacing your entire heating and cooling unit.

4.   There is a Blocked Line

Your HVAC unit has lines that absorb excess humidity in the air, converting it into water and then draining it from the system. If one of those drain lines become blocked, the moisture will convert into ice, especially if the blocked line is near the coils, which is the coldest area of the heating and cooling unit. For this reason, you need to opt for regular heating and air condition service in Irving, TX.

5.   The Thermostat Has Malfunctioned

Your thermostat tells the HVAC unit on whether it needs to generate cool or warm air. A malfunctioning thermostat will detect the wrong temperatures in your home or send your HVAC unit the wrong signals. This will result in your heating and cooling system to work harder than it should. This will also increase your energy bill. Schedule an appointment with a HVAC technician to come to your home to inspect the thermostat.
