The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.

I had a minor crisis at my home with a backed up sewer drain in the basement and me just home from a freak accident where I broke both arms! Spencer narrowed down the problem and called his coworker who had the equipment to snake my drain and stayed to clean up until the issue was resolved. He was courteous and careful to make sure my carpet didn't get marked up and cleaned up well. I am so grateful for him being willing to go the extra mile to help me out!

Don and Zac came out and assessed the furnace and explained why it was now time to replace it. Don explained in detail what we should look for (the job is bigger than his preferred scope) and the kind of furnace he recommended. When I asked him for his bill, he said, "Call it an estimate. No charge." I thanked them profusely and paid them in cookies. Affordable Furnace is a great business whose expertise and integrity you can trust.
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.

• If your furnace is inside the house, it may be located in an area that is magnifying the sound it makes – such as under a staircase. Often moving the furnace to another part of the house can reduce that noise. You may find that it’s in an area that was previously occupied by another older type of furnace, and you never heard those sounds from that one. Please keep in mind that modern furnaces are built differently – with multiple speeds and stages – which may create different sounds and require more airflow than your old ductwork has available. If the furnace doesn’t get enough air, it gets cranky.
