Types Of Heating Systems in Fairfax Virginia
1- Furnace
A furnace is a type of heating system that uses gas or electricity to heat homes. A blower in a furnace collects air, which is then heated by natural gas or electrical heating elements and distributed throughout the home.
Types of Furnaces
Gas Furnace
A gas furnace uses natural gas to heat the air. Gas furnaces are less expensive to operate and last longer.
Electric Furnace
An electric furnace generates heated air through a heat exchanger using electrical heating elements. Electric furnaces are less expensive to install and require less maintenance, but they can be more expensive to run and heat homes less efficiently.
Benefits of a Furnace System
A furnace system is less expensive in terms of fuel and uses less energy than other heating systems.
2- Heat Pump
Heat pumps take heat from the outside air and move it inside the house.
Types of Heat Pumps
Air Source Heat Pump
This type of heat pump draws hot air from the outside into the home.
Ductless
Mini-split ductless heat pumps are ideal for homes without ductwork or for heating specific areas within a home.
Heat Pump benefits
Heat pumps are an energy-efficient way of heating and cooling homes.
Components of a Heating System
When it comes to your heating infrastructure, you have two options: a heat pump or a furnace. Here are some of the benefits of each option
Air Ducts
They direct heated or cooled air to vents throughout your home.
Flame Sensors
These are gas furnace safety features that indicate whether or not a flame is present to ignite the gas.
Fan Blades
These blades are part of your heating system's fan. The fan circulates air throughout your home.
Ignitor
It is a pilot light or electric component that heats up the gas in your furnace to produce heated air.
Gaskets
High temperature gaskets seal the draft inducer blower and heat exchanger in heating systems.
Pressure Switches
These switches close to allow electricity to pass through and ignite the furnace.
Capacitors
The start and run capacitors in your heating system's fan motor provide power.
Types of Thermostats
Digital Thermostats
These thermostats have a digital display that allows a more precise temperature adjustment than the old manual thermostats.
Honeywell Thermostats
Honeywell offers programmable and non-programmable digital thermostats. WiFi thermostats, like the Honeywell Pro 9000, are programmable and provide convenience as well as improved energy efficiency.
WiFi Thermostats
You can change the settings on these thermostats from any location with Internet access.
Smart Thermostat
The Google Nest thermostat is a "smart" thermostat that learns your schedule and adjusts the temperature accordingly.
Common causes of heating system breakdowns in Fairfax Virginia
You never know when your heating system will break down. Even a regularly maintained furnace can fail. Some issues include:

- Dirty filter
- Damaged or slipped blower belt
- Electric ignition or pilot control problems, or other mechanical issues.
If you notice a heating unit cycling frequently, the pilot light flickering or turning yellow, or if you hear unusual noises, contact us at (703) 256-8080. This could indicate a worn ball bearing or clogged blower .
Our HVAC technicians can also determine whether a problem is caused by a faulty or incorrectly set thermostat. Our experienced technicians can quickly troubleshoot and repair any HVAC problem.
