With the summer heat arriving soon, you are going to want to make sure your air conditioning unit is in good shape. You don't want to find out that it is malfunctioning during a heatwave and find that you can't find an air conditioning repair person to come out on a timely basis. So it's important to test out your air conditioning unit and see if there are any issues. Here are some particular areas that you might have to deal with.
Sitting Water In The Base (Window Units)
If you have a window unit air conditioner, then you have a unique issue that you need to be aware of. Window units are exposed to the elements and they can be difficult to clean. If you live in an apartment building, then you might just leave the air conditioner in your window year round. If that is the case, then all the snow and water that hit the outside might be sitting in the base. While air conditioning units are designed to have small egress points for water, they need to be tilted correctly. If your unit was not angled correctly, much of the water and snow can sit in the frame base and cause rust.
So it is a good idea to take the unit out of the window (if possible) before the season starts and open it up. You can then clean up any dirt on the coils, and make sure that the fan has not rusted. If you live in a high unit apartment that has window unit air conditioners (such as in pre-war buildings in NYC) then you should be careful about attempting to remove the unit without proper assistance. You don't want to send it crashing down onto the sidewalk. You might ask the super of your building to assist you.
A Malfunctioning Fan
A malfunctioning fan will render your air conditioner unit worthless. The air needs to circulate over the cooling coils, and then blow into your living space. If your fan is broken, you should have it replaced. You should contact a HVAC tech to come out and deal with the replacement. If you over torque the replacement fan during the install, you could damage the machine, so it's something best left to the professionals.
Torn Air Filters
Most people are aware that they need to clean their air conditioning unit filters, but it's also wise to inspect the filters to make sure they are not torn. A large tear in the filter can inhibit air flow, and also lead to excessive dirt entering into the unit. This will lead to clogs and damage to the coils. So inspect the filter when you are washing it and if you notice any tears, replace the filter with a new one.
Clogged Condensate Drain Line
For large air conditioning units that are housed outside of your home, you will have to be aware of a potential clogged condensate line. If you notice that there is water inside your house, it is a sure sign that the condensate lines are clogged. There will also be a lack of power in your air conditioning unit. Some homeowners who are skilled at do-it-yourself can attempt to fix the clogged line by using a wet vac and finding the exterior access point on the condensate line and using suction to clean it out. However, it is often times simpler to have an HVAC repair person do it as part of your yearly cleaning.
Condenser Coils Are Filthy
As part of your preparation for the summer, you should have an HVAC tech come out and clean the coils. These sit outside and are exposed to all sorts of airborne debris, and they can get really filthy. If the coils are covered in grime, they will not be be efficient. A HVAC tech will have the proper tools to inspect the coils, see if any are bent, and also clean them so they work efficiently. Contact a company like A Bailey Plumbing to learn more.
