Two nights ago our smoke alarm went off during the night...after a frantic search through the house we traced the source of the smoke to the furnace.  After reading reviews about Affordable Furnace Repair we decided to give them a try...and we are SO GLAD WE DID!  Within 10 minutes of leaving a message I received a call back and was scheduled the next day.  The source of the problem was immediately identified and promptly fixed....a previous repair had messed up some wiring as well which was also fixed and now we are so glad to be back to 100%.  Can't say enough about the professionalism, responsiveness and service.  Highly recommend.


Ruud, Trane, and American Standard are among the more reliable natural gas furnace brands, whereas Goodman, Lennox, and Amana are among the less reliable brands. York, however, stands out as the least reliable brand and cannot be recommended by Consumer Reports at this time. That’s what we found based on the feedback of 21,618 subscribers, who reported on their experiences with gas furnaces installed between 2011 and 2016.
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.
