Payne Air Conditioner Coils Freezing. Unlike other HVAC malfunctions, frozen air conditioner coils can be caused by failures in almost any part of the system.
Someone on your team will notice frost or a layer of ice on your indoor unit and think that’s where the problem lies. Unfortunately, it’s not so easy to diagnose the reason for the failure.
It is important to note that there are many reasons why your air conditioner could be failing and we’ll explain both common as well as seemingly rare causes of a frozen AC.
Payne Air Conditioner Coils Freezing
Payne Air Conditioner Coils Freezing. The leading cause of a frozen HVAC system is a clogged filter. The filter helps keep the air delivered to your home clean during the hot days of summertime. As your AC system runs throughout the summer, it collects allergens and other types of dirt which can restrict the amount of air that can circulate in your home, hence making it more likely for ice to accumulate on the coils somehow.
We discuss some problems with Payne air conditioners when their coils freeze.
Coils Freeze Due To Refrigerant Leaks
The refrigerant is the chemical substance that flows over your air conditioning coil, evaporating to lower the temperature, and absorbing heat from the inside to cool the coil.
As soon as refrigerant leaks from the system, then the air conditioning system loses its ability to absorb heat efficiently and as a result, absorbs a great deal more heat than it should.
If this happens, you’ll find that all of your refrigerant lines will freeze over with ice, and each swipe of metal one line comes into contact with during its trip through the coil will be affected as well.
Frozen Coils Are Caused By Faulty Thermostats
Your thermostat works with your AC unit by regularly checking the temperature to make sure that everything is working properly.
If a broken thermostat senses a temperature that’s different from what it should be, or if it doesn’t have the program set right, then this could cause your AC unit to run too long and eventually wear out the system.
One of the most common problems associated with overworked AC units can happen when they become too cold. Left unchecked, an overworked AC unit could develop frozen condenser coils.
Blocked Condensate Lines Cause Frozen Coils
In your HVAC system, condensate lines are responsible for draining excess moisture caused by humidity. Condensed into the water, it moves through the pipes to a floor drain.
If this water is stuck in one place because of a clogged pipe, it can freeze.
This will happen especially if the obstruction happens near the evaporator coil, the coldest part of your AC. A blocked condensate line can cause the water and subsequently your coils to freeze.
Coils Can Freeze When Fans Break
You can keep your air filters clean, but it won’t help unless there is a fan that pushes air through the system.
It is possible that if you have a broken motor or even dirty blades on your fan, it could result in a lack of airflow and, in turn, cause the coils to freeze.
Filters That Are Dirty Can cause AC Coils To Freeze
Whether you have central air or a window air conditioner, you need to make sure that there is good airflow throughout your home.
If the filters get dirty, moisture can begin to build up and cause problems with the system it could overheat or stop cooling altogether.
If your AC is not able to cool off your house because there’s no clear airflow affecting the coils, your coils will be too cold, leading to ice formation within the unit.
