Is your AC freezing up? Isn’t that what it’s supposed to do? While this may not sound like a big deal, it can be startling to notice ice collecting on your unit. Fortunately, a frozen AC is a fairly common issue for homeowners, but that doesn’t mean you want to ignore it entirely. With help from the experts at JC & JC HVAC Mechanical Contractors, you can learn why your AC is freezing up and what you can do to stop it.
Blocked Airflow
Blocked airflow throughout your AC system is one of the most common causes of a frozen AC. Air conditioners need proper airflow to operate, and if it isn’t sufficient enough, your unit won’t be able to effectively process humidity. Blocked airflow typically results from clogged air filters or dust and debris in your system due to lack of maintenance.
Low Refrigerant
Low refrigerant levels are another major cause of a frozen AC. Refrigerant is one of the most important components that keep your AC functioning smoothly. When refrigerant lines are damaged or start to leak, you will experience plenty of problems — one of which is an AC unit that freezes. Your refrigerant levels should stay constant, so low levels are usually due to refrigerant leaks that necessitate an immediate call to an HVAC professional.
Clogged Condensate Line
Your condensate line removes the moisture created during the transfer of hot air from inside to outside your home. When that line clogs, it throws your entire system out of whack as it keeps the moisture inside your system and can freeze your evaporator coils. The best way to clear out a clogged condensate line is with help from an experienced HVAC technician.
Those Random Cool Nights
Did you know that random cool nights can be a major factor in the condition of your AC unit? Believe it or not, low temperatures can throw your entire air conditioning system for a loop. Air conditioning units are calibrated to operate at a certain temperature limit. When the cool air outside goes below that limit, your unit can start to freeze over.
What to Do if Your AC Freezes Up
So what can you do to prevent ice and freezing of your AC? Your first steps should be to get your unit back up and running so you won’t suffer from the summer heat. Just like you’d do if you encounter ice on any other object, it’s important to thaw your AC and then begin diagnosing the issue. Thawing your unit simply requires you to let the ice melt in the summer sun, which can take up to a day or two. While the coils are frozen, avoid using the unit, as it can put excess strain on your compressor. After the AC is thawed, you want to dry off your evaporator coils by running the blower or fan on your unit. This keeps any excess moisture from building back up on your unit until you can get problems diagnosed by an expert.
How to Prevent a Frozen AC
One of the best ways to prevent air conditioners from freezing is by getting AC tune-ups and HVAC maintenance from your local professionals. Besides that, there are plenty of other ways to keep the ice off your unit. Changing out dirty air filters regularly ensures proper airflow, and preventative maintenance can detect leaking refrigerant before the problem worsens. Either way, it’s important to know that a frozen AC is preventable, and following these tips can ensure you keep your unit running smoothly throughout the summer’s hottest days.
