We asked This Old House plumbing and heating expert Richard Trethewey to show us the proper steps that a service professional would follow for an oil-burning forced-air furnace; the basics on a gas system are similar. In both, fuel is mixed with air and ignited, heating a sealed chamber. Fresh, filtered air then blows across the outside of the hot chamber and into the heating ducts. (Homes with radiators have boilers instead of furnaces. These heat water instead of air, but the annual checkup is similar.) In all, the dangerous exhaust from the combustion chamber is vented out a flue or chimney.

Seattle furnaces can run nine months of the year. Based on the average temperatures in our area, if you compared running your furnace to a car it would get the equivalent of 1.8 million miles over its expected lifespan of 15 years. Your heating system will work hard for you, but like your car, doing routine and regular maintenance will keep it running smoothly, avoid problems, and keep your warranty intact.


CM Heating performed a Gas Furnace Diagnostic. Customer wanted his echo bee thermastat installed that he had bought himself. Furnace was working fine just wanted his thermastat installed. He thought that the $99 service fee was going to cover that but explained to him what the service fee was for, and explained that there is a additional install fee for the stat. Customer didn’t want to pay the additional fee so I called the office had them listen to the call to make sure we explained to the customer correctly and to see how they would like me to proceed. So I quoted the customer the fee to install the thermostat but he didn’t want us to install it so I left.
When a furnace maintenance is performed a combustion analysis should be performed to identify any problems that couldn't be found by a visual inspection. You want to know what the Carbon monoxide level your furnace is producing as well as the oxygen/CO2 levels and stack temperate. The analyzer will also give you a calculated efficiency rating with the information the analyzer receives. You should have >100ppm of Carbon monoxide output during normal operation of your gas furnace. When you have higher numbers or CO numbers increasing during operation their is a problem with the furnace the technician should then find the cause of. This is just a brief explanation I'm trying to get across to those who get their furnace maintained and to those who don't! Check to see if anyone in the company has a NCI certification for carbon monoxide/combustion analysis.

As touched on by their name, heat pumps function by transferring heat energy indoors during the winter and outdoors from your home during the summer. They're often attached to air conditioning units, using the surrounding air to transfer energy. However, geothermal heat pumps and water source heat pumps are also available. The cost to repair a heat pump, again, depends on the specific problem. Replacing a faulty thermostat may cost up to $300 including labor, while a worn or damaged defrost control board can set you back up to $600. For more details on your potential repair costs using this heating source, visit our heat pump repair cost guide.

Air Conditioning and your heating source are intertwined. In the summer it’s the AC system you’re concerned with. In the winter it’s the furnace.
