Customer stated their blower fan is consistently running. She has had the furnace off all summer and just fired it up and it will just blow consistently. Upon investigation, the technician found that the damper control was sending 24V to G terminal while switched off. This indicates a stuck closed relay. I disconnected it and tested the unit. Due to age of unit, I would recommend upgrading to a more efficient model.
If you pull out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most likely been a while since your last heating service, and likely time to get a new one. If it’s a simple disposable air filter, just replace it with a like-size new one. It’s also a good idea to write down the date you installed the new filter, so you know how old it is next time it needs to be replaced. Check the filter packaging to see how long the new air filter is supposed to be used.

I'd had them come out before and called because my thermostat wasn't getting power. They said they don't service townhomes. I said that must be a new policy because they've been out before and she said they've had it for awhile. I tried to ask why they don't service townhomes and she said they don't service attached homes or commercial properties. I said that my home isn't commercial and it doesn't really answer my question, but I guess I'll go elsewhere. I couldn't find this policy on their website and I can't really understand why a townhome furnace would be different than an unattached home. When they came out before I seem to remember they did a good job, so it's too bad they have odd policies now.
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 you have an older furnace with a standing pilot light, it’s possible that the pilot light has been extinguished. First, confirm that the light is out. Then, turn the gas valve to the off position and wait five minutes. If there is a reset button on your furnace, turn the valve to the pilot position and hold a flame to the dedicated pilot opening while pushing the button for about 30 seconds. (If the pilot doesn’t light on the first attempt, wait a few minutes and repeat the procedure, this time depressing the reset button for 45-60 seconds.) Once the pilot is lit, turn the gas valve back to the on position. If the pilot light won’t stay lit, it’s possible that there is an issue with the thermocouple or ignition system. Call an HVAC professional for assistance.

High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
