New Installation vs Repair

Whether you should repair your furnace or replace it is one of the most commonly asked questions of HVAC professionals. The answer of course is different for each homeowner. Age, upkeep and how much you use it can all make a difference. However, there are a few basics to keep in mind that will help you make the best decision now and going forward. 

Financial Tip: Follow The 5,000 Rule
Multiply the age of the equipment by the repair cost, and if that exceeds $5,000, then replace the unit. If less, go ahead and repair it.  

Repair Your Furnace:

  • If it’s under 15 years old.
  • If it’s performing consistently.
  • If rated 87% AFUE or higher.

Replace Your Furnace:

  • If it’s over 15 years old.
  • If requires multiple repairs in last two years.
  • If energy bills increase suddenly.
  • If rated lower than 56% AFUE.

How we got these prices

The prices featured here represent the most common average prices nationwide of each Trane product. Prices may vary in your area. Unit Cost refers to the product price only. Installed Cost includes the product price and the national average installation price. 

A note about installed cost: Installation prices may increase 20-30% depending on where you live. If your project requires new ductwork, the installation cost will increase $1,500 – $2,000. 

What factors affect furnace pricing?

Because no two homes and home heating needs are exactly the same, the total installation cost of a new furnace will be different from place to place. Here are the factors that can affect the cost of installing a new furnace. If you want a true cost estimate for your home, talk to a local pro.

Local Climate and Region

If you live in the North, the heating capacity of your furnace needs larger than a similar sized home in the South where the winters aren’t as severe. 

Home Size and Construction

A large home will need a larger capacity HVAC system or multiple systems compared to a smaller home – which will increase your total installation costs. Also, a well insulated home retains warm or cool air and may not need as large a system as a poorly insulated home.

Project Complexity   

If your furnace installation is extra challenging or requires custom parts or retrofitting, your costs will go up. Examples include installing a furnace in a hard to reach or small space or in a historic home that needs updates.


Evaluating your home’s ductwork is part of any new installation because poor ductwork can negate all the energy savings features of a new furnace or air conditioner. Adding new ductwork can add $1,000 – $5,000 to a project depending on the size of home.

Trane XB90 Furnace Reviews

Showing 1-5 of 6 reviews

"Response to review titled “Company owner”"

5.0 rating
Very Satisfied

I’m also a Trane dealer since ’05. I just want to say that “company owner” is spot on in his review. Do a decent job and you won’t have any problems. Plugged filters, plugged condensers, crappy, old wet basements, improper ducting, etc., raise chaos with anything. Way too many are in it just to rape people for a fast buck and their work shows it.


"Buy something else"

1.0 rating
Very Unsatisfied

Parents have this furnace for a few year. Built their house and furnace was brand new. Was told today they need a new furnace. The heat exchange (something with condensation) was busted and had rusted areas of the furnace. The furnace is 13 yrs old. Serviced 2 times a year. I sell insurance and have clients that have furnaces that are 100 years old with service contracts. Wth! Not happy. I have parents on a fixed income who can’t afford to replace a furnace. Not happy or satisfied.


"Love my Trane"

5.0 rating
Very Satisfied

We bought a Trane furnace over 5 years ago. The contractor that put it in made sure we had the right one for our house, and for many winters before our new furnace we always had to light the pilot light. It was always going out and we always had high gas bills. After getting the new one it is nice to flip it from air to heat without having to do anything, and our gas bill has gone down by a lot. I would recommend one. Only changing a filter when needed is very nice.


"Company owner"

5.0 rating
Very Satisfied

After reading the reviews on Trane furnaces I felt a need to respond. I am a Trane Comfort Specialist Dealer and have been for some time. I have been a Trane dealer since 1993. It is my experience that the large majority of equipment failures are not equipment related but installation and service related. I have found that 95% of all Trane equipment failures that my company sees is due to improper installation. To address some of the comments I have read. My company has not replaced one (1) flame sensor on any Trane furnace we have installed and serviced in the past 15 years. We have not had one (1) case of multiple control board failures in the same time frame and we have not had any heat exchanger failures. We, however, have repaired many Trane systems that have had failures in these areas and, as I have said, in 95% of the cases the failures have been caused by improper installation or maintenance. Do not confuse Trane equipment problems with poor installation and service. If the equipment was installed with out a manual “j” heat load or manual “d” ducting design, it is more than likely not sized properly or has inadequate air flow for proper operation and you will most probably have problems. Do not confuse high cost companies with Trane product problems. You are the one that chose the company that is working on your equipment, if they are over charging this is not the equipment problem. If the company cannot repair your equipment maybe you should look at the company not the equipment. Maybe it is a maintenance issue causing the problem with your equipment. Many customers do not see the need for routine maintenance on your heating and air conditioning systems. Your hvac systems have more yearly operational time that your car or lawn mower yet you routinely have both of these items serviced. But, again, the large majority of Trane equipment failures is caused by improper equipment sizing, duct work, electrical service (grounding), venting, etc. My experience is, over the past 20 years that I have been installing Trane equipment, Trane equipment is a well built, reliable and state of the art residential product. By the way my customer satisfaction rating of Trane equipment my company has installed is 98% with a 100% referral rating. If the Trane product was a bad product there would be no way to achieve these numbers. It is not the product it is the company installing or servicing the product.

"Could have been better"

1.0 rating
Very Unsatisfied

Furnace has been used through 7 winters. A friend (professional hvac repairman) gave us the sad news that the unit is no longer safe to operate (substantial cracks in heat exchanger). It also has a leak in the coil. The corrosion was caused by a galvanic reaction because of the use of dissimilar metals in contact with each other in a moist environment, brilliant! (I learned not to do that when I was just a wee co-op.) The propane control valve has also corroded to the point of not operating. There were a few other issues. All in all it will cost about the same to replace as repair. We’ll be replacing with another brand.
