Are you curious about how the HVAC system in your Shelbyville, TN home works? Here are some HVAC basics you should keep in mind:

Heating

The following parts make up the traditional heating system. Each part requires maintenance so that the unit runs efficiently. They are typically found inside your home:

  • Thermostat
  • Furnace
  • Heat exchanger
  • Exhaust
  • Blower
  • Vents

The furnace is the main part of an HVAC system. It has to be kept in top shape, which is an HVAC maintenance service we proudly offer. The furnace moves heated air through the ducts to deliver warm air throughout your home. You can use electricity, natural gas or fuel oil to power your ducted warm-air heating system.

Air Conditioning

An indoor coil is filled with refrigerant, which cools the air that is delivered through the ductwork into the rooms that have vents. To create cool air, energy is used to remove heat. There are several types of cooling systems with unique benefits:

  • Central air conditioners
  • Ductless mini-split system
  • Heat pumps

The type of cooling system that you choose depends on your comfort and budget needs. If you want to cool your entire home, then a central air conditioner is the right choice for you. However, if your home doesn’t have ductwork or you have a temperature preference for one of the rooms in your house, then a ductless mini-split will fit those needs. Similar to air conditioners, heat pumps can cool your entire home, but they reverse their cycle and heat homes during the winter.

Ventilation

Ventilation is important because it ensures that the air quality remains safe inside. Ventilation uses blowers, fans, and filters, as well as ducts for pushing and removing air from rooms with vents.
