We’ve all experienced the dreadful realization that our home isn’t cooling the way it should. You’ve waited for the temperature to match what you’ve set it on, but the thermostat won’t budge for some reason. When you make your way over to your outside unit, you find that it’s frozen over. What do you do now? Let’s talk about it!
Specialized Mechanical knows what an inconvenience a frozen air conditioner is. Most homeowners want to know why this happens and what they can do to prevent it. Below, our experts have broken down all you need to know about this common problem!
There are a couple of reasons your air conditioner could be freezing over. Let’s walk through the 5 most common reasons why.
1. Lack Of Air Flow
A common culprit of a frozen AC unit is a lack of airflow. If your unit damages its ducts, air cannot move properly through the evaporator coils. The condenser will continue to run, and eventually, the condensation will turn to ice. Scheduling routine maintenance on your unit will allow experts to spot any potential leaks or blockages in your ductwork.
2. Low Refrigerant Levels
When your air conditioner operates with low refrigerant, it can’t function properly. With such low-pressure, ice will start to build on the surface of your coils. A leak in the refrigerant lines causes low refrigerant.
3. Dirty Air Filter
Routinely changing your unit’s air filter is an easy DIY that any homeowner can do. If your filters are not changed, it will result in a build-up of dirt that will ultimately cause clogs that block proper airflow. Our experts at Specialized Mechanical recommend that your filters are changed every three months.
4. Clogged Condensate Line
If there is a clog in your condensate line, the drip tray could overflow with excess water that, combined with the moisture in the air, ice could begin forming on the evaporator coils. Our professional HVAC repair team will flush and clear out your unit’s condensate lines and have your system operating like new!
5. Damaged Blower Fan
The blower fan is in charge of pulling warm air into the coils. If the blower fan is not correctly working, it won’t send enough air to the evaporator coils and could cause your lines to freeze. A damaged fan can also cause damage to your whole system. It is crucial to get a technician out to inspect your fan.
Defrosting Your Air Conditioner
If you’re wondering how you can thaw your air conditioner, the answer is easy! All you need to do is turn your thermostat off and turn the fan to “ON” for a few hours. This will not solve any underlying issue your unit is having, but it will get rid of the ice.
