We are here to help you understand the most important factors in making this big investment for your home.

Here are four things to consider when buying a new furnace:


The first thing to consider when buying a new furnace is the size of the unit. Furnaces are measured in BTUs (British Thermal Units), which measure heat output.

To find the right size heating system for your home, you’ll need to know the square footage of your living space and the climate in your area. Then you can use a BTU calculator to determine the appropriate size for your needs. But it’s best to hire a heating installation expert to size your home when buying a new furnace.


Another important consideration when buying a new furnace is efficiency. The annual fuel utilization efficiency (AFUE) rating measures how much of the fuel used is converted into heat. The higher the AFUE rating, the more efficient the furnace.

Look for a furnace with an AFUE rating of at least 90%. This means that the appliance will convert 90% of the fuel it uses into heat.


High-efficiency furnaces tend to cost more upfront than their less-efficient counterparts, but they can save you money in the long run due to their lower operating costs. When considering cost, be sure to factor in both the purchase price and the estimated annual operating costs of each furnace you’re considering.

Warranties and Service Plans

Finally, don’t forget to consider warranties and service plans when buying a new heating unit. Most furnaces come with a manufacturer’s warranty covering materials and workmanship defects. Some manufacturers also offer extended warranties that cover parts and labor costs for repairs after the manufacturer’s warranty expires.

There are a lot of factors to consider when buying a new home heating system, but if you do your research, you’ll be sure to find one that’s just right for your home.
