If your furnace has a pilot light, look for the flame. Check your owner’s manual or the instructions posted inside the furnace cabinet for step-by-step lighting instructions. Usually this involves first turning the gas valve to Off and waiting a couple of minutes. Then you turn it to Pilot. Next, press and hold it down while you light the flame. Last, wait a minute or so, release it, and then turn it to On.
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. 

Finally, don't underestimate the thermostat as a potential reason why your furnace is not working. Everything on the heating unit itself may function perfectly, but your home still will not heat right if the console you use to set the temperature doesn't communicate your input. A faulty thermostat can either be due to the wall unit itself, or the wiring that connects it to your furnace. Average thermostat repair costs are between $108 and $282, including labor. Replacement costs, of course, depend on the thermostat you choose. Visit our thermostat repair cost guide to learn more about this type of issue.


CM Heating performed an electric furnace Diagnostic - Upon investigation, I found that the sequencer has failed which is why all heat elements are not being activated (3 out of 5 work). This is the second replacement sequencer needed in less than 5 years of operation, the unit is an old model of air handler and only source of heat. Replacement of sequencer is needed, however, based on age and efficiency recommend upgrade of system.
I met the owner while looking at a new house, he was servicing the furnace. I asked for a card and explained that I live in a townhome, he said not a problem. Well I called a day or so late to schedule an appointment. That went smooth due to the season the schedule was 3-4 weeks out. I understand and wait patiently. Week the day before the scheduled service i got a reminder call, those are helpful. Well the gal on the phone calls back a few minutes later she called back and came up with a few excuses on why they can no longer come look at my furnace. They seemed pretty hollow to me and she took a fairly snippy attitude with me as well. Due to hire this went down and the fact that it took a month for them to say no can do, I will never ever pay a positive wire forward towards this company!

Don has earned a lifetime customer! My wife and I moved into our fixer-upper house this summer and just when the weather turned we realized that the 8 year old Goodman furnace in our basement had rusted heat exchange pipes and was leaking carbon monoxide. (So much for the $400 I paid to an home inspector before we moved in...) Fortunately, the furnace had a warranty still active. Not so fortunately, Goodman was incompetent in getting us the replacement part. It took them a month to send it, and then it wasn't even the right part. Don went to bat for us and convinced Goodman to foot the bill for an entirely new furnace! He and another worker made time in their busy schedule during thanksgiving week to come out and get the unit installed. This is above and beyond service and I couldn't be happier.

A number of other variables can influence your decision on whether to repair or replace your furnace, as well. In addition to cost and brand, consider the expected lifetime of your furnace. If it is more than 15 years old, it might make more sense to invest in a new unit even if it costs more than simply repairing the current problem. Long-term costs also play into the equation. For example, your new furnace may be more energy efficient than the current unit. Even though you will pay more for the actual installation, you might be able to make back your investment through lower energy bills. To make your decision, consult with a reliable professional on what to do. In inspecting your furnace, they will be able to make an informed recommendation that looks not just to the next year, but years into the future. That way, you can make the best possible decision for your home and budget long-term.

If I could give them 10 stars I would. Don is extremely knowledgeable but more importantly honest. PSE had done a free diagnosis and told me I would need a new induction motor for around $850 or possibly a new furnace. PSE doesn't do the repairs so I found Affordable furnace on yelp. Don showed me where the noise was coming from and that we didn't need the other repair. He performed some routine maintenance and enlightened me on much better furnace filters. He said we will probably need a new furnace in a couple years but given the fact we've lived here 18 years and it was here before we got here I think we're doing pretty good. When it is time for a new furnace there's only one company we will be calling. Thanks Affordable Furnace!

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.
