Major Types of HVAC Equipment in Reston
There’s more than one way to heat and cool a home. Below is a quick break down of the equipment you might see in Virginia:
What Is It: This unit cools your home by removing heat and humidity from the indoor air. Known as a central air conditioning system, it operates with an outdoor unit and an indoor coil.
How Do I Know I Have One: Air conditioners use ductwork to distribute cool air throughout the home. The outdoor unit is usually found outside the house, while the indoor coil is placed in the duct system near the furnace.
Life Span (Years): 10-15
What Is It: It’s large, in-charge, and responsible for heating your home. Typically referred to as a central heating system, this piece is set apart from boilers by its lack of a tank.
How Do I Know I Have One: These units rely on ductwork to move warm air around. They’re typically located in the center of the home.
Life Span (Years): 15-20
What Is It: When it comes to flexibility, it’s hard to beat a heat pump. Able to alternate between heating and cooling, these units merge the functionality of an AC unit and furnace. They’re also ultra-efficient. These units can be ducted or ductless.
How Do I Know I Have One: You flip your thermostat to HEAT and the exterior unit turns on. You had to add an air handler.
Life Span (Years): 10-15
What Is It: In homes in Reston with central HVAC, the furnace’s blower motor is responsible for air distribution. For people with heat pumps or just air conditioners, an air handler is installed to take its place.
How Do I Know I Have One: You don’t have central heating but still have a large box in your home. It typically has a slot for your air filter.
Life Span (Years): 15-25
What Is It: Though sometimes able to alternate between heating and cooling, not all mini-splits are heat pumps. They’re a go-to choice for people who want to add air conditioning to a ductless home. They’re also an ideal option for additions and garages.
How Do I Know I Have One: These units feature wall mounted units called cassettes. You also lack ductwork.
Life Span (Years): 20-25
