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

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.

Ductwork

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.
