Is your furnace ready for winter? spring? summer?

A heating system converts fuel into heat which then flows through a house. The efficiency of a heating system depends on the amount of fuel consumed to meet heating needs. Using less fuel means your system has increased its energy efficiency.

An air-starved furnace can cause carbon monoxide to buildup in quantities that can be dangerous. Warning signs of inadequate ventilation are stuffy atmosphere, lingering odors from in complete combustion, back drafts and smoking fireplaces.

Improve heating efficiency

If you decide to change your system, you'll have to consider what type of fuel you want to use. Cost and availability of fuel is usually the deciding factor. If you're keeping your present system, here are a few ways you can improve its operation.

Turning down the thermostat is a good way to save heat. There are several brands of programmable thermostats on the market today that will regulate your home's temperature.

Hot air ducts are notorious wasters of heat and money. If your basement feels too warm, too much heat is probably seeping out of your ducts. You can seal all joints and seams in the ducting with vinyl duct tape. Some ducts registers empty into the basement and these should be sealed or closed if they are not needed.

Ducts that run through unheated basements or attics should always be insulated. Fiberglass batting or commercial duct wrap can be used.

Make sure both return air grills and supply registrars are kept free from any obstruction, including drapes and furniture. With forced air-systems, the furnace filters should be changed regularly.

If you think you might be having problems with household air supply, contact a registered heating contractor for advice. If the problem turns out to be inadequate air supply, the contractor will be able to find ways to bring in outside air. There are specific requirements for this which depend on the type of system you have.
