December 19, 2018

The cost to install a furnace in Boise ranges from $3,800 to $11,500+, with an average cost of $6,700.

Since you’re a smart shopper, you probably want to know what determines price so you can get a better idea of what you’ll pay for a furnace installation.

The only way to know exactly what you’ll pay for a new furnace is to have a technician visit your home and provide a quote.

However, to give you a better idea about overall pricing, we’ll share the following factors that affect price:

  1. The furnace unit itself
  2. The warranty you choose
  3. The cost of labor

Let’s go into more detail about each of these factors…

Factor #1: The furnace unit itself

Furnaces can vary in size, fuel type, efficiency and features, which means the cost can vary from unit to unit.

We’ll explain more…

Furnace size

The bigger the furnace, the more expensive it will be.

Furnace size is measured in BTUs (British Thermal Units) which is a measurement of heat. The more BTUs a furnace has, the more powerful it will be.

Residential furnaces typically range from 40,000 to 120,000 BTUs. However, you don’t get to choose the size you want.

To find out what size furnace you need, you’ll need to contact an HVAC professional to perform a heat load calculation. This calculation takes into account several factors to determine what furnace size matches your home.

Furnace fuel type

You can choose between gas or electric furnaces. Gas furnaces cost more upfront than electric furnaces, but they usually offer lower monthly energy bills (since gas is the cheaper fuel source here in Boise).

Most Boise homeowners opt for gas furnaces, unless they don’t have access to natural gas lines. In that case, you’d probably want to stick with an electric furnace.

Furnace efficiency

High-efficiency furnaces are more expensive, but they also help lower your monthly energy bills.

Furnace energy efficiency is measured in AFUE (Annual Fuel Utilization Efficiency). The higher the AFUE rating, the more expensive, but energy-efficient, the furnace will be.

Electric furnaces have an AFUE rating of 95%–100%, but gas furnaces have different AFUE ratings depending on the type of furnace:

  • Conventional (mid-efficiency) furnaces = 80% to 84% AFUE
  • Condensing (high-efficiency) furnaces = 90% to 98.5% AFUE

Wondering what AFUE really means?

Let’s say you have a 95% AFUE furnace. That means that 95% of the gas your furnace uses is turned into heat, but 5% of the fuel is wasted during the heating process. Said another way, for every dollar you spend on heating, $0.95 is goes towards heating your home while $0.05 is lost to gas waste.

Furnace comfort features

If you opt for advanced comfort features in your new furnace, that will raise the total cost of the unit.

Examples of advanced comfort features include:

  • Variable-speed blower motor: This type of blower motor adjusts its speed incrementally, which  improves comfort by eliminating hot/cold spots in your home.
  • Modulating burner: A modulating burner adjusts its heat based on how you set the thermostat, which provides a more constant indoor temperature and lower energy bills.
  • Smart thermostat: While a thermostat isn’t necessarily part of the furnace itself, it can be installed alongside your new furnace. Compared to old, manual thermostats, smart thermostats offer more accurate indoor temperatures (+/- 1° F from how you set your thermostat).

Factor #2: The warranty you choose

If you opt for an extended warranty, you’ll pay more upfront for your furnace.

We’ll explain more...

Furnaces come with 2 basic types of warranties:

  1. Limited parts warranty (from manufacturer)
  2. Limited labor warranty (from contractor)

All furnaces come with a limited parts warranty, which means the furnace manufacturer will replace faulty parts within 5–10 years (depending on the manufacturer) from the day the furnace was first installed.

And most contractors will offer some sort of limited labor warranty that guarantees they’ll fix the furnace if it breaks down within 1 year from the install date.

However, you also have the option to purchase an extended parts and/or labor warranty. True to their name, extended warranties “extend” the length of coverage offered by a limited warranty.

For example, most extended parts warranties will cover faulty parts for 10 years, and most contractors that offer extended labor warranties will guarantee their installation work for 5–10 years.

Note: We offer a 10-year, worry-free parts and labor warranty on all new furnaces we install.

Factor #3: The cost of labor

More experienced, reputable contractors charge more for their services than less experienced contractors (who sometimes also do lower quality work).

When it comes to installing a new furnace, the last thing you want is to hire a contractor who isn’t experienced and cuts corners. A poorly installed furnace won’t heat your home as well and will require more frequent repairs.

So, how do you find an experienced, high-quality contractor here in Boise?
