How Much Does Furnace Replacement Cost?

  • Efficiency

    New efficiency laws require most furnaces to adhere to new energy standards. Furnaces with a higher Annual Fuel Use Efficiency (AFUE) Rating can cost more up front. But it may save you over the long haul -- particularly if your furnace is more than 10 years old.

  • Energy Source

    Whether your home uses electrical, gas, or oil is a major factor. If you already have an electrical system, it will be easier to retrofit a new one. Moore recommends electrical for its low cost of installation, low maintenance requirements and longevity.

  • Your Household

    Cost depends on household factors including, but not limited to, the design of your home and its size. If your furnace needs placed in a hard-to-reach location, it could cost more. You can tack on additional costs for optional features, such as noise reducers and smart thermostats.

Bob and Juan did a great job installing a mini-split AC/heat system in our Eichler.  I can earnestly recommend Moore for this type of work -- they were efficient, courteous and quick and fairly priced. Thanks for a job well done. – David R.

Just had Karl come and do the tune up of my air conditioner and furnace, and what a sweet guy! He gave me many recommendations on how to keep my equipment running smoothly, what filters are better for my furnace vents, as well as not making me feel like an idiot when I didn't understand something. – Angel G., Windsor

Huge shout out to Ira Quackenbush!  My first experience with this company and now I believe I will be a loyal customer.  Ira came out to do a basic "check".  We'd lived in this house for a couple years and never had our systems checked - it's an old house and an overdue inspection.  Ira was super thorough, kind, friendly and knowledgable. – Tina O., Santa Rosa

Today, the Moore Technician, Kevin, arrived on time, thoroughly tested my furnace, replaced broken parts - including my thermostat- explained the process and said my furnace has some life left.   I signed up for the annual service and Kevin will come in the spring to service my a/c which is included in my annual contract - very reasonable.  Kevin was so friendly, clear, thorough, and helpful. – Maglyn I., Santa Rosa

Jason came out back in November and confirmed our fears, but he did an excellent job at helping find a solution and explained in detail how to remedy the problem. A few weeks later Kazu and Tony came out and in just one day installed new ducting (11vents in total). They were both super nice and very courteous (Highly recommend both of them). Also included in our quote is a post assessment. Trevor and his team came out and measured ...

I grabbed an Amazon Local coupon for these guys for a $19 furnace inspection. What I got was a thorough, detailed assessment and tune-up. WAY more than I expected. Nick was courteous and knowledgeable, and I know that if my heating or air system fails, this is the company I'd choose to do my repairs. Thanks, Moore! - N L., Novato

We chose Moore to replace 2 furnaces, upgrade to a tankless water heater, add attic insulation, upgrade and move some gas lines, remove and replace an asbestos duct, repair our broken A/C and add solar panels!  My wife Andrea is very picky and when she didn't like one thing they had done in the garage, they came right back out with a bigger crew and found a way to change it and she is very happy. We would highly recommend Moore! ...

The unit in my living space is absolutely wonderful.  It is solar powered.  It runs quietly and yet is powerful.  But mainly want to write a review about the service technician, Brad.  He was fast, friendly, curteous and knowledgable.  Usually I dread when I have a service visit, but he made it easy and comfortable for me and I really appreciate that.

I actually didnt think theyd just come out for $20 & figured Id have to haggle & deal with a hard sell for a new furnace but I was pleasantly surprised that was not the case. JR did give recommendations to consider but I felt he was genuinely interested in helping me  & I will def call Moores when the time comes for further work. - Bianca M.

Great customer service, our tech Brad was very knowledgeable and efficient. Did a full inspection on our hvac system, recommended repairs and was able to come the very next day to complete the job. Great service. Will definitely use them again. – John L, Rohnert Park

Great service...Fixed air conditioning unit within a half hour and was very informative about my appliances and how to maintain them correctly to improve their longevity.  I signed up for the yearly maintenance program, upon the recommendation of Jason, my service professional. I feel very confident in his service and got great advice.  Jason was wonderful to work with! – Stacey L., Santa Rosa

They were out to our house within 24 hours of our initial call. They started the work within 48 hours of our agreement and were done over a three day span.  Purchased a new furnace and AC unit from them. Robert (Bob) and Rene were the main installers that installed the system and they were very professional checking in and out during the project. I highly recommend using Moore on your next project. - Kevin T., Santa Rosa

So grateful for the wonderful service we've received from Moore!  We had an entire new HVAC system put in this year and the initial install to the follow up service has been outstanding!  Today Karl was out to do a follow up service and helped tremendously with a question we had.  Super helpful and very kind! - Denise R., Petaluma
