Gas Furnace Repair

Gas furnaces use a heat exchanger, or a metal box, to keep your room warm. Inside is a pilot light, which is connected to the fuel source (such as natural gas or propane).

How Do Gas Furnaces Work?

Gas furnaces use a heat exchanger, or a metal box, to keep your room warm. Inside is a pilot light, which is connected to a fuel source such as natural gas or propane. The pilot light is also connected to your thermostat, which is how you’re able to control the amount of heat needed at various times without having to go into the furnace. Air enters the heat exchanger through your ductwork. After the air is heated, it blows out the other end.


Why Use a Gas Furnace?

Using gas to heat your home is typically less expensive than using electricity – up to 50% less expensive. That’s because natural gas is currently cheaper than electricity, and power companies offer very affordable gas plans. Newer furnaces are extremely efficient and use less energy than the older models. Eco-conscious customers like gas because it’s a clean-burning fuel that does not harm the environment and actually reduces demand for electricity in an area.

Some say gas furnaces just feel warmer, and they are correct; gas furnaces quickly warm the air at the vents to temperatures of 110 and above. This makes a home quite toasty in a short amount of time.

Finally, because gas appliances are desirable, having a gas furnace can actually increase your home’s value. This could be worth considering if you are planning to sell your home.

 Increases Home Value

Ask a real estate professional and he or she will likely tell you that people ask about natural gas availability when looking for new homes. They want comfort, convenience, and lower heating bills – the result of converting to gas.

Gas Furnace Safety

There are some important safety rules to follow when using a gas furnace. First, if you smell a faint odor of gas while your furnace is cycling on, you have nothing to worry about. If you smell gas throughout your home, there could be a leak that requires immediate attention by an HVAC professional.

When gas burns, it emits carbon monoxide (CO) that is vented outside of the home. Old or unmaintained units, or units that are blocked by dirt or insulation may leave the carbon monoxide in the air. This is extremely dangerous! We urge you to have carbon monoxide detectors installed. There is no other way to detect carbon monoxide because it is odorless and colorless. Exposure to carbon monoxide can cause harm or even kill you. If your detectors indicate its presence, get out of the house immediately and call for help.

Furnaces 101

One of the most important things to remember when you have a gas furnace is this: If you smell gas in your house, do not try to turn off the gas leading to the furnace, and don’t turn any lights on or off. Get out of the house immediately.

You should leave the door open and then call the gas company or fire department to report a leak. Do not go back into the home for any reason until you receive the all-clear.

If you’re looking into getting a gas furnace and you don’t already have gas, the expense of adding it is something that should be considered. Some contractors would suggest that you install it between the floors of a two-story house, but that’s not always the best option; because heat rises, you could end up with a hot second floor and a freezing first floor.

High-efficiency condensing furnaces are more complex than conventional furnaces, because of the combustion process that is put in place. Both use gas burners with an electronic ignition, but the difference is that the condensing furnace has a more efficient heat-extracting process.

If you have any questions about gas furnace repair in DFW or the surrounding area, call H&H Heating and Air today. We’re available 24 hours a day, seven days a week, for emergencies.
