Signs of a Poor Furnace

Having a properly working furnace in your home is important. If you notice anything out of the norm with the HVAC system, make sure to contact us as soon as possible. We can inspect the system and furnace for you. Here are some signs to tell if your system should be replaced soon.

1) Age

You should replace a furnace that’s over 15 years old with an ENERGY STAR rated furnace, which is 15% more energy efficient than other furnaces on the market.

2) Heating Bills

A variety of problems could be causing this. But if you have repaired the furnace and the air ducts have been properly cleaned, your energy bill should not increase dramatically. A sudden increase in your heating bill from the years before may mean that your furnace is on its last legs. As internal parts wear out, your gas and electric bill may go up. The extra money you are paying in gas and electricity could go towards buying a new furnace.

3) Repairs

Furnaces incur the most repairs during the last two years of their lives. Like a repairing an old car, it does not take too many repairs before keeping your old furnace running is not worth the cost. Add up the cost of repairs to your furnace over the last two years and see if it is cost efficient to buy a new one.

4) Odd Noises

When the furnace is operating, does it make any rattling, popping, or banging noises? Older furnaces make these strange noises at the end of their life. Also, does your blower turn on and off frequently? Does it blow cold air? This is another sign that your furnace needs to be replaced as soon as possible.

5) Thermostat

Are some of your rooms too hot or too cold? Are you constantly adjusting the thermostat to stay comfortable? If so, it may be because your furnace can no longer distribute heat properly throughout your house. The furnace may have issues, as well as the thermostat.

6) Burner Flame

If your furnace’s flame is yellow instead of blue, it could be a sign that your furnace is producing carbon monoxide. Carbon monoxide is an odorless, tasteless, and colorless toxic gas that can be fatal.

If you notice any signs or anything out of the norm with the furnace, make sure to contact us to set up an appointment as soon as possible. This can help you to reduce time, money, and stress in the long run.
