Modern gas furnaces have an electronic ignition that starts the burning process. Older furnaces, though, have a standing pilot flame. The pilot flame ignites natural gas entering the furnace, leading to your home being heated. The pilot flame can occasionally go out, requiring it to be restarted. Here are the steps to doing so safely.

Turn Up the Thermostat
Before getting started, turn your thermostat up to a setting that will turn the furnace on. 80 degrees is sufficient. Also, make sure the thermostat mode is set to "HEAT." This will cause the furnace to turn on once you have restarted the pilot light.

Locate the Pilot Light and Controls
Take off your furnace's lower cover. There are two common types of controls. One control method has a gas valve with "Pilot," "On," "Off" and a reset button. The other control method has a knob with "Pilot," "On," "Off" and no reset button, but the knob can be pressed. In either case, turn the control to the "Off" position.

After turning the pilot light control to "Off," you need to wait five minutes before doing anything else. This gives time for any lingering gas to clear away.

Relight the Pilot Light
You need either a long match or a butane BBQ grill lighter. Turn the control setting to "Pilot." If you have a reset button, push it. If you have the other control system, then press the knob. You can then place a lit match or ignited lighter just above the pilot light, reigniting it.

You'll want to keep the knob or reset button pressed for about 30 seconds. If this doesn't relight your pilot light, repeat the above steps.

No matter how skilled a technician is, repair is not always the best option for a furnace. When the appliance is old, breakdowns become more likely. If you're frequently repairing the furnace, then it probably needs to be replaced. Here are two general rules on how to know whether you should repair or replace your furnace.

Is It Over 15 Years Old?

If your furnace is over 15 years old, you should replace it. An old furnace is likely to break down again after being repaired because of its old age. Furnaces are designed to last 15 to 20 years with good routine maintenance. If the appliance hasn't been tuned yearly, then it might need to get replaced before the 15-year mark.

One of the major problems with an old furnace is higher energy bills. You probably don't want to be surprised one month by your energy bill doubling or tripling. It's best to have the furnace replaced before it begins giving you grief.

Are Repair Costs More Than Half the Price of a Replacement?

If repair costs are more than half the price of a replacement, you should replace the furnace. This is especially true for an old furnace. You don't want to risk having to pay for another repair the following year before having to pay for a replacement shortly after. Many high-quality furnaces come with a manufacturer's warranty. And if you pay for professional maintenance once a year, they are unlikely to need expensive repairs.

It's heating season in Broussard, LA, which means you're likely looking for ways to keep your home comfortable while saving on your energy bill. One of the questions our customers most frequently ask our technicians at Dave Broussard A/C & Heating is whether we recommend allowing their furnace fan to run continuously. Read on to learn whether keeping your furnace fan in the "on" position is an efficient way to heat your house.


The Stack Effect

Hot air is lighter than cold air. Therefore, the heated air in your home naturally rises when the cooler air falls to lower levels. This phenomenon is called the stack effect. Continuously running your furnace fan allows air to circulate throughout your house, thereby balancing the warm and cool air. We offer furnace fan inspection, repair, and installation services to keep your home comfortable.



Impact on Your Electric Bill

You're likely wondering if running your furnace fan continuously will affect your electric bill. If your furnace has an Energy Star rating, it's equipped with a variable speed motor that's designed to run continuously, adding only a few additional dollars to your energy bill. Older models may add an additional $10 to $12 to your monthly heating bill. Over time, running your furnace fan continuously will likely cause your energy bill to decrease as a result of achieving a more consistent desired temperature throughout your house.



Consistent Heating for Single-Story Homes

The stack effect mostly applies to homes that have rooms on more than one level. Nevertheless, you should opt to continuously run your furnace fan if you live in a single-story house. Your residence likely experiences different temperature zones from sunrise to sunset. Operating your furnace fan will provide more balanced heating throughout the day and night regardless of how much sun exposure each room in your home receives.

Conventional heating systems powered by fossil fuels create emissions that are destructive to the environment. Greener options exist that cut down on those harmful gases and are friendlier to your wallet, too. Here’s a look at some of those alternatives.


Geothermal Heating Pumps


According to the Department of Energy, the most environmentally friendly method of heating a home or place of business involves using a geothermal heating pump. These pumps have two components: a heat exchange unit that functions like a conventional heat pump and a set of pipes buried four to six feet underground that harvest the earth’s heat. The heat exchange unit depends upon electricity to operate.

Since geothermal heat pumps don’t rely upon fossil fuels, they produce relatively few greenhouse gases. They’re also much less costly to operate. The U.S. Environmental Protection Agency estimates that homeowners may save between 30 and 70% on heating bills with a geothermal pump.


Pellet Stoves


Pellet stoves burn fuel made from compressed wood that’s been recycled. Pellet stoves are basically a highly efficient type of wood stove. While 40 to 50% of the heat generated by a traditional wood-burning stove dissipates up the chimney, though, only 10% of the heat generated by a pellet stove is lost.

Pellet stoves are equipped with blower components that function as an active smoke extraction system. The cost of the pellets necessary to heat a 1,500-square-foot home throughout the winter is markedly less than the equivalent amount of firewood.


Solar Heating


Solar energy is another power source that’s free of harmful carbon emissions. Once you invest in solar panels, you will also see a significant drop in your utility bills. Solar panels contain photovoltaic (PV) cells that convert sunlight into direct current (DC) power. Sophisticated technological storage solutions allow you to access that current even during the night or on cloudy days.
