The Mr. Furnace Blog


Every homeowner is likely to need to replace their furnace eventually, and the options can be confusing. This guide will help you decide which furnace will best fit your home and lifestyle.


For many reasons, efficiency tops the list of qualities to look for first in a new furnace. Whether you are trying to be more eco-friendly and your green dream includes using less energy, or you simply want to see lower heating bills every month, efficiency is the answer. The less energy is wasted, the less total energy it takes to heat your home, lowering your usage considerably. Look for products sold which are rated for how much energy is wasted while they run, by a trustworthy name.

Although pilot lights have been the standard for years, the market is starting to see options for instant ignition -meaning less energy wasted keeping a pilot light running.


To get the most out of your new furnace unit, at the lowest operational cost, it is important that the unit be sized correctly for your home. It is no surprise that smaller units burn too much energy working so hard, trying to keep your home comfortable. But it may surprise some that units that are too large waste energy as well, by turning on and off much more often than needed. A correctly sized furnace will run optimally with the lowest energy usage. To determine the best possible size furnace for your individual home a calculation using house size and construction will be used.


Single stage furnaces have been the standard, but they are not the most fuel efficient, and they are louder than other types. Two stage units can be less noisy and are often better at creating even heating. If your interest is in upgrading your furnace or found that your old one was too loud, you may want to consider a modulating unit. Not only is it more efficient than other models, but modulating furnaces are better at keeping your space consistently comfortable and much quieter.

Fuel Supply

While this next item may seem obvious, it is often overlooked when shoppers first begin looking at new furnace options. If you are not going to switch your fuel type for other reasons, you will likely not want the expense of switching it for a specific furnace. It is, therefore, likely that you will want to limit your furnace choices to models that use the same fuel type that you already have installed.

This might be considered less of an item if you are having your furnace moved for other reasons, as the cost of changing fuel types may overlap with prepping the new location.


Budget is a consideration for everyone, and there is no doubt that home furnace replacements can be an expensive investment. But it is an investment, and it can pay off easily if you plan carefully for your needs. When considering how much to spend on a new home furnace, calculate how much you are likely to save with greater fuel efficiency, and consider how long you anticipate staying in your current home. If the time it would take you to recoup the costs of your new furnace is greater than the number of years you are likely to stay in your home, it may not be the right choice.
