Although most HVAC units are very dependable even on the hottest days, there are always things that can go wrong. The crucial thing to note is that you do not want these things to go wrong during those smoldering Southern California Summer days in Los Angeles. With this in mind, you can see why it is important to be prepared for anything, and preventative maintenance is worth its weight in sweat. Here are some of the most common HVAC problems.
Air Filters Need Cleaning
In most cases, when an air conditioning unit stops cooling as well as it once did, the cause is most likely dirty filters. This is because an HVAC unit simply cannot run efficiently when the filters are clogged with dust, dirt, and grime. The unit sucks air through the filter in order to cool your home. When the filter is clogged, the HVAC unit cannot “breathe” and therefore it cannot do its job. It is a good rule of thumb to change the filters in your HVAC unit once a month, and even more often if you live on a dirt road or have a lot of dust in your area.
Gas Valve Leaks
Leaks at the gas valves of HVAC units are also a common problem that a heating and cooling contractor may see from time to time. When the refrigerant is leaking from your air conditioning unit, the air will continue to blow, but it will not be cool air. If this happens with your unit, the exact point where the leak is coming from may be difficult to find.
It is best to call a licensed HVAC contractor if your air conditioner starts blowing warm air. He or she will have the equipment needed to find the leak and repair it for you.
Blown Fuses
Another problem that is common in HVAC units is blown fuses. When fuses are blown in your air conditioner, it will cease to work properly. This is because these fuses are in place to protect the compressor or motor of the HVAC unit from becoming too hot.
In many cases, when someone thinks that the motor in their HVAC unit has blown out and will no longer work, it is simply a blown fuse. These fuses are located in the evaporator coil of the unit. A licensed HVAC repairman can easily determine whether or not your HVAC unit has blown a fuse, and if so, he or she can replace them for you quickly.
Clogged Drains
Your HVAC unit has a condensation pump that is designed to drain the water that comes from the unit. If this pump fails to function properly, or the drains become clogged, the condensation will not drain, and water damage can occur in your home.
This issue also causes the HVAC unit to function improperly, resulting in more energy use to keep your home cool. When this happens, of course, the electricity bill will tell the tale. It is important that you keep watch to make sure that water is not pooling around the outside of your HVAC unit from clogged drains or a broken pump. If there is water, be sure to call a licensed HVAC technician immediately.
Proper care and maintenance of your HVAC unit will keep it functioning properly for years to come. Keeping an eye out for these common problems can go a long ways towards saving you money. Preventing an issue is much cheaper than repairing one!
