Keeping Your HVAC System In Great Condition

There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.

What To Do When Your AC Freezes Up

Herbert Franklin

It can be quite frustrating when the air conditioner in your home stops working during the hot summer. One reason why this can happen is due to a refrigerant line that has frozen. It means that the refrigerant inside cannot cycle through the compressor, and the condenser coil cannot remove the heat from the air so that it is chilled. Here is what you can do to troubleshoot the issue.

Inspect Your AC Evaporator Coil

When the air in your home starts feeling warm, the first thing to do is shut down your home's air conditioner with the thermostat. Ice will continue to build up the longer that the AC runs, so turn it off as soon as possible to allow it to thaw. Once the system has been off for a bit, open the cover on the blower so you are able to see what is happening with the evaporator coil.

There should be a part that forms an upside down V shape, which is the condenser coil. Beneath it will be the drain pan. If the refrigerant line is frozen, there will be ice on the condenser coil. Do not scrape off the ice on the coil by hand, since this could damage the coil. Instead, leave the HVAC system off so that the coil can thaw naturally. The ice will melt and fall into the drain pan on its own.

If there is a large amount of ice on the condenser coil, you can run just the fan to blow room warmer air over the ice, which can actually help speed up the thawing process.

Check Your HVAC System For Air Restrictions

The coil can also freeze due to air restrictions in the blower housing. If the air cannot leave the blower, it will cause the coil to get colder than usual and form ice on it. Start by checking the filter and see if it is clogged. A clogged filter is easy to swap out with a clean one, but if ignored, it will essentially trap the cold air from getting out.

If the filter looks  clean, you could have a problem with a leak in the refrigerant line. Contact a local HVAC service company, like Lee Air Conditioners Inc, to repair it for you. They will find where the leak is located, repair it, and recharge the HVAC system with more refrigerant so that you can have cold air once again.
