HVAC Repair: Things That Could Go Wrong with Your Unit

HVAC Repair: Things That Could Go Wrong with Your Unit

HVAC is an acronym that stands for heating, ventilation and air conditioning. These three systems are often combined into one unit that is useful for heating or cooling down your home. A HVAC unit works by air (cool, warm, or dehumidified) passing through pipes called ducts to circulate in all of the rooms in your home. The HVAC unit is an integral part of living comfortably in your home, and should be kept up with to catch potential problems before they occur and create a need for a very costly HVAC repair.

Different Systems

There are two different types of HVAC systems. One type is the “split system,” in which the condenser is placed outside and the evaporator coil is placed inside. They transfer heat from inside of your home to outside if the heater is on, and they transfer cool air from inside of your home to the outside when it’s cold outside. To create heat, liquid refrigerant is required. The compressor expands this refrigerant and it turns into a gas, which then flows to the evaporator coil. This gas absorbs the hot air inside of the ducts and leaves the cooler air to circulate through the ducts and your home. The gas then gets sent back to the compressor and the process begins again.

The other type of HVAC system is called “packaged,” and it still has the same condenser and evaporator coil units. The difference is that these are put together to comprise one unit, which is placed outside. The cooling/heating process is still the same as the split system. Whichever system that you choose depends on where your home is located and how it has been constructed

Potential Problems

No matter which system is chosen, they’re both going to have their fair share of problems. If your unit is not working properly, it may be a sign that one or more components need repairs:

  • Refrigerant pressure levels being off
  • Air filters being faulty or need to be cleaned
  • Ducts need replacement
  • Evaporator coil needs repair/replacement
  • Blower wheel and/or motor needs repair/replacement
