Do’s And Don’ts Of AC Maintenance

Does your home have central air? Does it seem like your air conditioner is not working properly? If you are noticing reduced airflow, or if the air coming out isn't as cold as it should be, there could be a number of possible causes. Of course, you could just call an HVAC tech to come to your home and check everything out. But, you could save some money if you are able to find and fix the problem yourself. The problems are often small and easy to fix, even for those with no experience in HVAC. Here are two things you should check if you think your AC is not working properly:

The  AC Condenser Hose

It is always a good idea to start at the AC condenser hose. This hose connects the condenser unit to the duct system. There is one connection on the back of the condenser, and the other is on the side of the house. From there it feeds into the ducts. Checking this vital junction could save you time and money. Many people just fail to check the hose because it is behind the unit and hard to see. Even during the day, you will probably need a flashlight to give it a full inspection.

First, makes sure that both ends of the hose are tightly connected to the fittings. Some hoses are screw-on, but others are secured with a hose clamp (these are most vulnerable). Also, make sure there aren't any holes in the actual rubber. It is a good idea to have the AC running while you are checking the hose. If you feel cold air flowing, there is likely a hole or gouge in the hose and you should replace it immediately.

The Evaporator

Most people don't know exactly what the evaporator actually does. It is not important to understand the technical details of a how an evaporator in an AC system works. It is most important to know where it is and how to clean it. A clean evaporator will undoubtedly improve the cooling process, while also causing your condenser to use less electricity.

The evaporator is on the inside of your home, usually right next to the furnace. It is housed in an aluminum boxed that should be about 1' on each side. Open the access panel and door to this box and you will see the evaporator. This A-shaped device is made out of metal and wrapped in copper coils. The space between the coils is going to get caked in dust over time. Cleaning off this dust will improve the functionality of your evaporator. Don't scrub the coils too vigorously because they can get damaged. Gently wipe them down and vacuum out the compartment.

These are two cheap and fast jobs that might vastly increase the efficiency of your AC. Contact an HVAC company for more information and assistance with air conditioning maintenance
