Top 3 Issues Causing Problems with Your HVAC Unit

When the weather gets its most extreme, your family’s comfortability relies on your HVAC unit. Used for regulating the temperature inside of a home, your HVAC unit does a lot of work throughout the year. And while no one ever wants there to be an issue with their HVAC system, with use, age, and improper maintenance, problems that break or minimize the efficiency of your unit can and do arise. To keep homeowners in the know, here are the top three issues that can cause problems for you HVAC unit.


Bad Ductwork


In order for your HVAC unit to function properly, all of its components must be in good working order, including the ducts. Ducts, although seemingly insignificant, play a big part in having a running HVAC unit. According to, leaking ducts can take out 20 to 40 percent of the energy of an otherwise perfect unit. For this reason, it’s vital that you always ensure that your HVAC unit’s ducts are sealed and insulated properly in order to have the best supply of hot or cold air into your home.


Clogged Drain Lines


Because central air conditioning units create condensation, drain lines are an essential part of your HVAC system. Joe Truini of shares that when your unit is dripping water outside near the air conditioning unit, you know that the line isn’t completely clogged. If it were, there would be no dripping. Instead, there would be pooling of water that could then cause water damage to both your HVAC unit and your home.


If you suspect that your HVAC unit has a clogged line drain, which, according to Truini, happens most often due to algae buildup, you should seek to get that drain cleaned out as soon as possible to avoid experiencing an untold amount of property damage. When removing extra water from your HVAC system, it’s best to have a professional complete the project for you.


Thermostat Issues


At times, your air conditioner may appear to not be working correctly although you can’t see or tell that something is wrong with it mechanically. Nicole Harms, a contributor to Angie’s List, explains that homeowners will likely become aware of this when the air condenser isn’t running or when there isn’t adequate air cooling taking place.


For issues such as this, try adjusting the thermostat before assuming a bigger problem is at hand. By simply adjusting the thermostat down by five degrees for either one of the above issues, you can troubleshoot whether the problem is just a malfunction of the thermostat or something larger that may require calling in a professional.

In an ideal world, no one would ever have any issues with their home comfort systems; the air would be hot when we needed it and cool when we needed it. But since this isn’t the world we live it, it’s best to know what to be on the lookout for when you do experience problems with your HVAC unit.
