Furnace replacement

Have you ever noticed that it's pretty much the coldest day of the year when our furnace stops working?!


Well it may seem that way to you, but we're thankful that's not really the case.


We're busy repairing and replacing furnaces throughout the cold season.

How furnaces work is pretty simple.

There are two types of vents in your furnace.

One set of vents is connected to the "intake" side of your furnace.

That's where the furnace draws air IN (1).

The air is then blown across the HEATED sources of your furnace (2).


Then it's distributed within the ducts to all of the other vents throughout your home.

Considerations for replacing your furnace

Furnace replacement can be an intimidating process. There are nearly 100 different brands and thousands of different models to choose from. They include budget models, mid-efficient models, and high-efficiency models.

Repairing and/or replacing a furnace is NOT a do-it-yourself job. Replacing or installing HVAC equipment will require the help of a fully-qualified and licensed HVAC contractor. HVAC equipment often involves handling high-voltage electricity, plumbing and gas lines, and in some cases, venting combustible gases or refrigerants.

There's nothing more important than proper sizing.

Size matters. One of the biggest mistakes other contractors make is assuming that your previous furnace was properly sized. 

How can I know the proper size?

There's only one way to do it right: Load calculations (see HVAC definitions). Any contractor who says "we have enough experience, we don't need to do them" could really mess you up! You can know with certainty we are not installing a new system until the load calculations are done.

Which fuel source should I choose?

Electric, gas, propane, or oil. Gas is the most popular. Oil and electric are typically the most expensive. They all have their benefits, and it's best for us to discuss all of them before you make your decision.

What type of unit should I get?

High-efficiency models are typically more expensive upfront, but in the long run, they cost less. Just remember high-efficiency may mean higher complexity.

Other factors:

Manufacturers offer discounts and rebates at certain times. If you'd like to be notified of our latest deals, email us and we will definitely let you know what's available. Some units run quieter than others. With more than 1000 different models, we are certain we can find a furnace that matches your budget and your requirements.
