Read this Before You Buy a New Furnace.

So, you have this nagging thought that it might be time to replace your furnace. Which, if you think about it, is a whole lot better than being forced to replace it. The more time you have to search out and weigh your options, the more likely you are to make a remorse-less decision.

For purposes of this blog, let’s assume it’s a given that you need one. And now let’s examine some key things to consider before you sign on the dotted line.

Correct Sizing

Oversized furnaces cycle on and off too often. That in turn will shorten the life of your furnace while driving up energy costs vs. installing a right-sized system that runs consistently over a longer period of time.

The only way to determine the right size furnace for your home is to have a heat load calculation performed by a qualified HVAC professional. While square footage certainly enters into the equation, so do insulation values, house layout, condition of your air ducts, and more.

Gas vs. Electric

There are two main types of furnaces to choose from: gas and electric. Gas furnaces are the more economical choice as natural gas is currently in abundant supply. Conversely, electric furnaces are typically more expense to purchase and operate. If you don’t have access to natural gas where you live, you can also consider a propane fired gas furnace.

Quality Assurances

Before purchasing a furnace, get to know your chosen contractor and satisfy yourself that they’re licensed, insured, have plenty of experience, and take the time to answer all your questions vs. trying to get you to make a rushed decision. You also want to know to what extent they guarantee your satisfaction and that they service and repair what they sell. Don’t think of this as an isolated purchase, but rather the start of a new relationship. Having the right heating and cooling contractor on your side will prove to be an endless source of peace of mind.
