Hot southern nights are great if you write atmospheric novels. They’re not so great if you’re trying to get a good night’s sleep and your air conditioner isn’t working properly. If your AC is freezing up, you want to know who you can call for AC repair service in Duluth, GA. It’s also good to understand why things aren’t working the way they’re supposed to. So, what causes an air conditioner to freeze? Here’s what we’ve seen.

Low Refrigerant

You may have a leak somewhere in your system. This can result when parts vibrate and rub against each other over time or if fittings are loose. Leaks can cause pressure in the evaporator coil to drop, then moisture collects and freezes on the coil. Ice builds up until your air conditioner can no longer function. An air conditioning company in Duluth, GA, can find the cause of the problem and fix it for you.

Defective Blower Motor

An air conditioner can freeze up if the blower motor isn’t working correctly. If the outside part of your air conditioner runs, but inside it isn’t operating correctly, you may have a defective blower motor. Thankfully, that’s an easy fix for AC repair services.

Insufficient Air Flow

Lack of proper air flow through your AC can impact the evaporator coil and eventually cause the unit to stop working and freeze up. Airflow issues can be the result of a faulty fan, closed or blocked ducts and vents, or, more often, a dirty air filter that lets dirt collect on the evaporator coil and clog it. An AC repair company can tell you if that’s the problem, whether the filter is too small, or if the problem is something else.

Only Part of the Problem

If your air conditioner freezes up, turn it off immediately. Letting it continue to run can damage your system. Diagnosing and repairing your system should be left to an HVAC professional. You can only see the tip of an iceberg, most of it is hidden from view. The same may be true if you can see ice on the outside of your unit. That’s just the visible tip of the problem. Trying to repair or replace components yourself can void the manufacturer’s warranty and cause damage. Your best decision is to call for AC repair.
