How Does A Furnace Heating System Work?

The Ins And Outs Of Your Home Heater

Here in San Antonio, it can feel like cool weather will never arrive. However, after summer and “hot”-umn, you’ll eventually need to switch on your furnace and throw on a coat. You may be familiar with how your air conditioner works, but do you understand your heating system?

If you’re wondering how heaters work, Wright Services can help. We’re dedicated to providing San Antonio homeowners with comfortable homes year-round through HVAC maintenance and repairs. Before you turn on your furnace this winter, read up on how the system heats your home!

Does Your Heat Run On Gas or Electricity?

Your heater will function differently depending on whether it’s electric or gas. Whereas electric furnaces use high-resistant wires to heat your home’s air, gas systems rely on natural gas. If your heat system has a small, blue pilot light, you have a gas system.

How Does Central Air Work With Furnace?

Whether your furnace is gas or electric, the basic way it distributes warm air throughout your home is the same. The gas burner or electric heating element warms up, and this heat is transferred to moving air that is blown by a fan through the heater. The warm air is then distributed throughout your home’s ductwork and vents.

How Is Temperature Regulated?

As a homeowner, you can control the temperature of your home with a thermostat. The temperature control, located on the furnace control board, turns on the electric heating element or ignites the gas burner when the temperature of your home drops below the set temperature on the thermostat. The temperature control will also signal the heating element to turn off when your home is warm enough.

How Is Exhaust Removed From The Heater?

Electric furnaces don’t need a vent since they don’t produce exhaust. However, gas heaters can produce toxic gases that are harmful if left uncontained. This is why gas furnaces have flues, or vents that remove this exhaust and release it outside.

If your furnace doesn’t have a proper vent, carbon monoxide may be released into the air. Signs of a carbon monoxide leak include the following:

  • Yellow pilot light
  • Feeling dizzy or nauseous
  • Frequent headaches
  • Confusion or loss of consciousness

Carbon monoxide is very toxic, so it’s important to leave your home if you suspect a leak. Always make sure you have a functioning carbon monoxide detector to alert you to any signs of danger.

How Do I Maintain My Furnace?

In order for your furnace to function properly, you’ll need to schedule annual maintenance. A furnace tune-up prevents damage and can help your heater last as long as possible. When you schedule a tune-up, you can expect our HVAC technicians to answer questions perform the following tasks:

  • Replace air filter
  • Inspect thermostat
  • Clean the exterior and interior of furnace
  • Inspect electrical connections

At Wright Services, we suggest scheduling a furnace tune-up every fall before the cold weather arrives. In San Antonio, that means you can plan to hire an HVAC technician in October or November. With a little extra care, you can keep your furnace running smoothly for many years.
