Construction Tips For Beginners

I'm glad you stopped by my website. I am Rafael Singleton. I always felt that there wasn't enough information available for those who would like to do a little renovation or those who would like to engage in their own construction projects. There is a lot of information that would be helpful for a professional construction contractor, but I always had a difficult time navigating the resources out there as a layman. I'm the type who always likes to take the initiative to get something done if I notice nobody else stepping up to the plate, so I decided to create this website focused on construction.

Construction Tips For Beginners

Why Is Your Air Conditioner Freezing Over?

by Dawn Henry

There should not be any ice hanging from your air conditioner. This is a sign that the unit is not functioning properly -- and in many cases, ice buildup prevents the unit from functioning at all. The good news is that in most cases, the problems that cause air conditioners to freeze over are pretty simple issues that you can address yourself with minimal DIY knowledge.

A lack of air flow over the evaporator coils

When your unit is functioning properly, the air conditioner's coils get super-cold, and then warm air passes over them, raising their temperature. If there's not enough air flow past the coils, they get too cold -- and then they freeze over.

A lack of air flow over the coils is often caused by weeds, shrubs or brush blocking air flow to the outdoor condenser unit. Blocking the air return vents in your home may also have this effect. So, clear any brush away from your condenser, and make sure there's no furniture on top of your cold air returns. There's a good chance your freezing problem will melt away.

A dirty filter

If there's nothing blocking the condenser or air returns, then the problem might be that your air filter is too dirty. When the air filter is dirty, your AC unit can't force air through it fast enough, so the circulation of air past the coils slows down. Changing your air filter is easy. Locate the filter -- it's usually found between the indoor air conditioning unit and the main air return duct. Pull the old filter out of its slot, buy a new one in the same size, and slide it in. Then, make sure you do this every month in the future so you don't run into the same problem again.

Dirty coils

If even changing the filter does not work, it may be that the coils themselves are dirty. The dirt begins acting as an insulator, slowing the transfer of heat to the coils and causing them to become too cold. To clean your condenser unit, begin by turning power off to the unit. Then, remove the outer cage. Spray the coils down with a coil cleaning solution (sold at most home improvement stores). Let the coil cleaner work its magic for as long as is recommended on the label, and then rinse the coil with the hose. Put the cage back on and restore power to the unit.

If none of the above issues seem to be to blame for your AC unit freezing over, it's time to call a specialist like one from Comfort Solutions Heating & Cooling Inc. The final possibility is that the refrigerant levels are too low, and this is an issue that needs to be addressed by a professional.
