Forced Air Furnaces in Santa Rosa

Call Us to Replace Your Furnace in Marin or Sonoma County

Furnaces that are 50 years old or older are very inefficient. In older systems, a lot of gas is wasted as it escapes up the flue pipe and therefore cannot be used to heat your home. Very old furnaces are usually just 40 to 50% efficient and waste up to 60% of the energy used. Today, John Owens Services, Inc. proudly installs furnaces with up to 90% efficiency that only waste 3% of the energy used.

Furnace Rebates Available!

Anywhere from $850-$2,000.

The Dangers of Using Damaged Furnaces

All furnaces eventually corrode and crack. Why is this a problem? A furnace is really a tin can with a flame inside and air is blown over the can to warm the home. The tin can or core of the furnace is called a heat exchanger, and when it cracks, the burning gases or combustion byproducts pass into the air that we breathe in the house.

This could lead to:

  • Health problems including respiratory conditions
  • Headaches and nausea
  • Death by carbon monoxide poisoning

Since 2010 carbon monoxide detectors have been required on each floor level of a house. Most people are unaware of this. PG&E recommends using carbon monoxide detectors on any gas furnace over 15 years old. After 15 years, the metal in the heat exchanger has been stressed thousands of times and could be prone to cracking and causing leakage into the home.

Many furnaces in Marin County are 25 to 35 years old (the serial number can indicate the date). When these furnaces were new, they were only 75% efficient. Over time through wear and tear, mineral buildup, and corrosion, they are probably only 50 to 60% efficient. When we go to repair one of these older furnaces, we always make the homeowner aware that the repair cost may only be the first of many on a furnace that could fail or crack at any moment, and it may be a better option to replace the furnace.
