You are running high energy bills and you are thinking maybe it's time to replace your old furnace with a modern, more energy-efficient one. Buying a new furnace is not only costly, but it will also take you a long time before you can recoup your investment.

Besides, your old furnace still has several years of mileage left. So before you go for a new furnace, consider ways you can make your current one more energy efficient.

Regular Maintenance

Regular maintenance will keep your furnace operating as it should and reduce energy loss. Ideally, this should be done before the heating season. Change your filter before and after the heating season. But often times, regular maintenance is not enough; more needs to be done.

Energy Audit

Have your utility company conduct an energy audit of your home. This will reveal how energy efficient or inefficient your home is. It will also identify areas that need improvement. Your furnace repair technician will be able to advise you on measures you can take to reduce energy loss. Such measures may include more weather-stripping, insulation or sealing air leaks.

Seal leaks in ducts (the pipes that convey hot air around the house) and re-insulate all the way from the crawl space to the attic. Replace duct tape with duct mastic. This will seal all gaps in the duct, even the invisible ones.


Consult your plumbing and heating maintenance company on possible upgrades. Look at the possibility of having an electronic ignition instead of the standard pilot light. It is not unusual to find that your furnace is too big for your house. Reducing the size of the gas burner's orifice (if allowed by law) will also increase your furnace's energy efficiency. This should be done by a furnace repair technician.

Programmable Thermostat

If you do not already have a programmable thermostat, get one installed. This device will regulate energy use according to need; such as controlling temperatures when you are asleep or away from home. If you already have one, confirm that it's working efficiently.


Over and above maintenance, for older furnaces, consider reconditioning the furnace. This involves replacing old parts with new ones. Inspect and buff the heat exchanger, inspect and clean the flame sensor and pilot assembly, test the gas pressure, test carbon monoxide emission, adjust temperatures and clean and inspect the burner port.

Making your old furnace more energy efficient will prolong its life, save you money, and give you more time to plan for a new one. For more information, contact a company like Able Plumbing-Pumps & Well Service.
