Look for These Six Furnace Warning Signs

It is important to know the six warning signs that your furnace may be on it’s last legs. It is especially important not to wait until a crisis occurs as this could lead to higher costs . A cold night in January, with the furnace not running efficiently or worse, completely broken down, is not the time to assess your heating system. Start now!

1. Age of your furnace

A good place to start is to compare your furnaces age to the national average. The average life expectancy of furnaces in homes today is between 16 and 20 years. If your furnace is close to this age or older, you should begin shopping. Shopping for a replacement furnace in an emergency does not allow time to make your best decision. Most people prefer to replace their furnace as a planned home improvement rather than a panic replacement when your furnace is faltering or failed.

2. Gas & Electric Bills Increasing

Increase in gas and electric prices are not the only reason for high bills. Furnaces often lose their efficiency as they age especially if they have not been properly maintained. As a result your furnace may run longer to provide the same amount of heat. This will cause your gas & electric bills to go up.

3. Furnace Repairs in the last 2 years

It doesn’t take long to spend $500 just to keep an old furnace running. Furnaces incur the most breakdowns in the last 2 years of their lives. Another repair sign is whether you had to wait to get parts replaced. As a furnace ages, it gets harder to get replacement parts.

4. Is your burner flame yellow instead of blue

A yellow or flickering flame may be a sign that poisonous carbon monoxide could be created by your furnace.

5. Is your furnace making strange noises

Old furnaces often start to make some strange noises as they get toward the end of their life. Have you heard any banging, popping, rattling, or squealing noises coming from your furnace? This is a sign that your furnace definitely needs to be looked at and may need to be replaced.

8. Is your house dry or dusty

Old furnaces often lack the ability to moisturize and clean the air in your home. Your house air may feel stuffy or stale. Does anyone in your family suffer from allergies to airborne dust, mold, pollen, viruses or dander? Or does anyone suffer from dry nose, dry throat, or dry skin? These signs all suggest that your old furnace is not capable of providing you with the comfort you and your family may want.
