Why does my AC Freeze?

Why does my AC Freeze?

We all know the drill during summer months here in Gardner and Raleigh. It gets hot. We crank down the thermostat and send our air conditioner into overdrive to try and keep us cool. Everything is great until your air conditioner freezes up. A frozen A/C unit can ruin a hot summer day fast. You may be wondering how an A/C unit can even freeze when it’s working around the clock in 95 plus heat? There are few reasons for an air conditioner to freeze up, and it doesn’t matter whether it is a window unit or a central air conditioner, the reasons and fixes are exactly the same for both. There are two fairly common reasons why your unit may freeze, even on the hottest day of the year.

An A/C unit that freezes up may be an indicator of a lack of airflow to the system. Air conditioners are designed to drop the temperature of your house by taking heat from it. If your air conditioner is not properly blowing your inside air over the evaporator coil, then this heat exchange cannot take place and the coolant that should be removing heat from your home, is not. Over time, its temperature will continue to drop and your air conditioner can freeze up. The problem is usually a dirty air filter. If the filter is clogged with dirt and debris, this could be the blockage that is causing your A/C unit to freeze. This is a simple problem to prevent. Change out the filter with a clean one and remember to replace the filter every four weeks.

If blocked air flow was not your problem, then there’s the issue of refrigerant leaks. Whenever you’re leaking Freon or other coolant, it’s a decision point for homeowners. When you have a leak, it’s best to either get it fixed or invest in a new A/C, depending on the age of your current system. Yes, you can get an HVAC company to top off your coolant and get your system up and running again. However, this is a short-term solution and there’s no telling how long it will last. It could go a couple of months, a couple of weeks or a couple of hours before your A/C is frozen again. If the leak is major and the repair is expensive, you should consider replacing your air conditioner, especially if it’s old.

A frozen air conditioner not only doesn’t work properly, but over time can permanently damage your unit. Regular maintenance for your air conditioning unit will help keep your system performing well.
