An electric furnace provides warmth by moving air over and through a series of coils. Ductwork and vents then distribute that air to the individual rooms in your home. Repair costs will depend on both the brand and the exact nature of the problem, but tend to be lower than some of the options above. That's because the units are small, and issues tend to be contained within the heating elements themselves. Expect to spend less than $300 on your electric furnace repair, depending on the exact problem.
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.
Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
