Common HVAC Problems

Posted at April 1, 2013 | By : | Categories : Blog | 0 Comment

Your home’s HVAC (heating, ventilation, and air-conditioning) system includes a number of complex components that must work in unison to make your indoor living spaces more comfortable all year-round. Like any complicated electrical system, individual HVAC components that malfunction or operate poorly can influence the operation of the system as a whole, which can lead to a host of issues, some of the most common being:


  • Busted Thermostat – Many instances of heating and cooling systems breaking down are caused by a broken thermostat; an issue that can be fixed quite quickly. Before jumping to a conclusion by calling a repair company though, make sure the thermostat is on first. Yes, there are many times in which the thermostat has been accidentally turned off or is on the wrong setting.


  • Leaky Freon – Freon’s the chemical compound that’s used as a refrigerant, an essential component for the proper function of an HVAC unit. Without it, your HVAC can’t cool the air. Freon should actually last indefinitely . . . unless there’s a leak of course. The first step any contractor will do when called to inspect a malfunction unit is check the Freon levels. It’s important to get a Freon leak under control as it can reduce the efficiency of your unit and cause your electricity bill to rise.


  • Dirty/Clogged Filter – Filters get dirty and clogged from air particles; I mean, that’s what they’re there for anyway right? Once this happens, the filter needs to be changed out. A good way to tell if the filter needs to be replaced is to hold it up to the light and see if you can see light pass through it. If you can’t, then the filter needs to be swapped out for another. If left unchecked, dirty filters will reduce the air flow to the unit causing the unit to freeze-up.


  • Blown Fuses – Found within the evaporator coil, fuses are in place to protect the unit’s motor or compressor against the threat of overheating. When it’s suspected that the motor may be going bad, the breaker is one of the first things the technician checks. At first thought, a simple blown fuse may not seem like a big problem at all, but on occasion they can be an indicator that something more serious may be going on with your HVAC system.


This extremely short list of potential problems you may encounter with your HVAC unit is merely the most common ones out of many other issues that could ‘rear their ugly heads’ throughout the life of your home’s HVAC unit. Whatever you do, don’t ignore the signs that more serious problems could be around the corner.
