PROJECT

Not everyone is familiar with the different types of HVAC equipment that exist to make heating and air conditioning possible. As time goes on, HVAC equipment changes for the better, usually being more cost effective or energy efficient. Knowing some of the basic pieces and their functions could help create a better understanding of how an HVAC system operates. Gas Furnace Maintenance Toronto

Not all HVAC systems are the same, but many of them contain the same parts that are needed to work together as a system. Whether you have the ability to do it yourself or you need to contact an HVAC specialist, these parts that are consistently working together to keep the overall system running smoothly. Let’s do a rundown on some HVAC equipment.

HVAC Coils

There are two types of HVAC coils in a typical HVAC system; a condenser coil and an evaporator coil. The condenser coil aids in heat exchange, and just like it says in the name, it condenses the hot refrigerant gas by being pumped outside and put under pressure to turn into liquid. The condenser coil then helps to release the heat, and the refrigerant comes back inside to the evaporator coil. The evaporator coil, usually found in the air conditioner, is where the household air goes through to be absorbed and turned into cold air. This air is then blown through the ducts.

Air Handler

An air handler is an indoor metal box used for both heating and cooling. It contains the blower, which is what sends the air through your home, as well as the evaporator coil. Depending on the size of the HVAC system, it’s available in different sizes and different speeds. It’s one of the most important parts of the HVAC system. It’s how your cool air and warm air reaches you.

Refrigerant Lines

Refrigerant lines are the metal tubes that the refrigerant runs through on its way to the evaporator coils. Refrigerant is what causes the cooling. The condensing unit vaporizes the liquid into gas and goes to the evaporator coil as liquid. These tubes can handle many temperatures, from normal to extreme.

Furnace

The furnace is a large unit, usually hidden away in a basement or a closet. The furnace is the HVAC system’s heat supplier. Heat is sent from the furnace to all the ducts of the home. There are different types of furnaces with different types of heat sources. For example, a gas heating furnace uses gas and oil.

Single Stage Furnace vs. Two-Stage Furnace

The single stage furnace has an on and off function, allowing the user to have full control. The two-stage furnace works through the thermostat. The thermostat is used to determine whether hot air or cold air is needed. The two-stage furnace is beneficial for saving energy because the furnace turns off on its own when the temperature reaches an appropriate level.
