The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one.
Start with your utility company; they can help a great deal. Comparing previous bills isn't always a good measure, as the weather is never exactly the same month to month. Instead, if you take your energy bill and divide it by the square footage of livable space in your home, don't count areas like unfinished garages or basements -- you can calculate how much you are spending to heat or cool each square foot of your home. Your energy provider can tell you what the average cost per square foot is in your region for that same period of time so you can compare apples to apples.

My furnace thermostat stopped working, and when I called Dehlia answered the phone and set up an appointment. They charged less for a diagnostic call than larger companies. They are actively licensed, bonded and insured. Verne arrived 2 days later, explained what was broken in my 17 year old furnace and gave me an estimate and time of replacement for a new furnace. Dehlia confirmed via email and phone, and Don and Zack showed up as promised on time a week later and replaced my Bryant 90i furnace with a new Rheem 96% efficient 2 stage Variable speed 85,000btu gas furnace Model #R96VA0852521 and provided me with the paperwork warranty and removed the old one. Cost was $5,394.90 including tax. I gave up on trying to get 2 more estimates because every furnace company wants $125 to $200 to come out to do a diagnostic and this company wanted $75 to come out to look at it although admittedly they just took a look at it and said it was broken and repair would be $2 to $3k and should just get a new  one (this fee was waived when I agreed to buy a new furnace from them). They also said it was possible I could find cheaper installation elsewhere, but I was freezing in December and I just wanted heat and other companies were 2 to 3 weeks out for an appointment.  They were pleasant to chat with as they worked and Don updated a convoluted furnace exhaust piping system. They accept cash and check after a job is finished with no deposit up front and are clear that 3% is added if you pay via credit card.  Overall I am happy with my new furnace although I sure wish I could've replaced it myself to save some money.
