4 Most Common Reasons Why Your HVAC Freezes Up

Summer in Long Island is just around the corner! Warm sunny days mean picnics in the park and swimming in the pool! But with temperatures reaching as high as 82°F, some people prefer to stay at home and rely on their air conditioning systems for comfort. Despite the staggering heat, many cooling air conditioning systems seem to freeze up during the summer. Top HVAC Long Island knows that there’s nothing more frustrating than a faulty AC in the middle of summer.
When your AC is freezing up, here are four reasons why:

1. Faulty Blower

Dust-ridden filters and dirty coils are the most common cause of damaged blowers. Unfortunately, there are no easy fixes when it comes to faulty blowers. HVAC contractors often ask you to replace your unit. Fortunately, it doesn’t have to end this way. By having your AC serviced and cleaned regularly, you’ll be able to prevent blower damage and ultimately extend the life of your air conditioning system.

2. Dirty Filter

As mentioned, a dirty filter could potentially damage your AC’s blower. But other than that, a dusty filter can also restrict the airflow in your home. When airflow is restricted, there won’t be enough air to flow through your AC to keep your coil from freezing. Make sure to change or clean your filters and have your AC tuned up every year to prevent damage.

3. Low Drainage

Low drainage lets condensed water to stay inside your AC unit, causing it to freeze. When your AC is on, water vapor condenses and turns into liquid and then drains into the drain pan.However, if your coils are frozen, this can block the drain hole and eventually damages your system. Simply put, ice on coils make the damages the drainage, which causes your AC to freeze. There are other factors that block your AC’s drainage, including sticks, pest activity, and even leaves.

4. Refrigerant Leaks

Refrigerant leaks are one of the most common causes of an AC freeze. If your AC is leaking Freon or another form of coolant, you should either get it repaired ASAP or purchase a new one. You can ask a reputable HVAC company to top off your coolant and get your AC running again.But sadly, this is only a temporary fix and there’s no way to determine how long it will last. The best preventive solution is to have it checked and cleaned regularly.
