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.

"LEMON !!!"

1.0 rating
Very Unsatisfied

Trane xl 80 mid efficiency, two stage. Researched the heck out of furnaces and found Trane makes Sears house brand…so sounded great. One week after installation, the mother board went down. No problem, part but not service call covered. Cost :90 bucks. Ten months later, flame sensor misbehaving; service call 90 bucks again. Few more months of summer and the appliance works perfectly! Oh right, no need to turn on cause its summer! Last year, first cold snap…furnace will not ignite beyond initial stage one blow ( 3 minutes) so we call service tech for yet another 90 bucks. April, some cheap made in Mexico wire snaps costing me another 90 buck service call and 20 dollars in parts. Just last night, return from movie to cold house…wife curses…oldest son kicks furnace. I call Trane local rep…no response. I call all Trane service reps…no answer. Inside temp is now 52 degrees; outside temp is 12 degrees. Not very pleased and would suggest Trane should be more responsive to customer inquiries as all my calls have been met with stoney silence. Nice work TRANE. I look forward to telling everyone I know what a poor product you make.

"Humidity Off"

3.0 rating

New Home: Purchased a Trane 100,000 btu 92% Two Stage furnace model tux2c100a9482a, the humidity when it was turned on created a humidity level of 27%(which started to pull all the wood appart). We added a top of the line automatic humidifier that generates an average humidity of 34%. I have to run a portable unit to get the humidity to get the humidty up. Still looking for the answere of why the humidity is low after many calls to Andy’s Statewide Installers.
