A frozen AC unit is a very common problem, especially when temperatures start to soar. While it is a frustrating problem to say the least, a frozen air conditioner doesn't mean that your unit is failing or that there is an expensive repair bill on the horizon.
There are several things that may cause your air conditioner to freeze up, such as poor air flow, a dirty coil and blocked vents. Fortunately, you can fix these problems yourself. Following are three things you can do to fix your unit if it keeps freezing up.
Replace Your Air Filter
How often do you replace your air filter? If you're not replacing your filter with a quality replacement filter at least every two months, your unit might not be getting enough air. Even if it seems like you've replaced your filter recently, it might still be clogged. This is especially true if you have pets or an excessive amount of dust in your home. If your AC unit freezes up, the first thing you should do is replace your furnace filter.
Clean Your Evaporator Coil
Your unit is equipped with an evaporator coil, which needs a constant flow of fresh air to work properly. If it is dirty, your air conditioner may freeze up. Fortunately, a dirty evaporator coil is an easy fix. To clean yours, mix a solution of bleach and water: one part bleach to three parts water. Then switch the power breaker to your unit off. Afterwards, locate your evaporator coil by removing the service panel to your air conditioner, and scrub the coil and dry it thoroughly with paper towels.
Check Your Vents and Ducts
A couple of other things that may be causing lack of air flow are blocked vents and dirty ducts. Check all your vents to make sure that there aren't any clothes or furniture blocking them. If all your vents look fine, shine a flashlight in them to check your ducts for blockages. If you notice a great deal of dust and debris in your ducts, you may have to clean them out to restore proper air flow to your unit.
If, despite all your efforts, your unit continues to freeze up, you will have to call a repairman, such as those at Always Ready Repair. However, it is well worth the time and effort to try to find and fix the problem yourself before calling for help. After all, you don't want to pay for a service call if you only need a fresh filter.
Hi there, my name is Marissa Sonder. I would like to use my site to talk about the different types of furnaces available for residential and commercial applications. Growing up, my school had an actual boiler room that provided heat and hot water for the entire building. All of the students loved to go down to the boiler room and learn about all of the components down there. Although many buildings have moved on from this old piece of equipment, I would like to discuss its use in detail on this site. I will also talk about modern electric, natural gas, propane and oil furnace systems. Thanks for coming by.
