Choosing the Most Suitable Outdoor Furnace

Is your furnace correctly sized? An oversized furnace has a large capacity and because of this could cost more to operate than a correctly sized furnace. Large furnaces cycle on and off too often and this is why it is more expensive than running consistently for a long period of time.

You need to ask a contractor to help you with load calculation to evaluate the capacity of your furnace. A load calculation accounts the size of your house, the insulation value of your windows, the amount of insulation in your walls and roof and other important aspects to determine the appropriate furnace capacity.

Ask your HVAC contractor if a load calculation was performed before you accept the furnace they recommend. If you are replacing your furnace some contractors may tell you that you should simply buy a furnace that’s as large as your previous furnace however, what if the previous contractor did not perform load calculation? Therefore you should request that they perform a load calculation before anything else.

Is the efficiency of your furnace the most suitable for your home?

Annual Fuel Utilization Efficiency (AFUE) rating describes the amount of heat that your furnace emits. An 80 percent AFUE means that furnace will convert 80 percent of the supplied fuel directly into heat. High-efficiency furnaces typically cost more upfront than low-efficiency furnaces. But these tend to cost less to operate on a month-to-month basis as they use less fuel to generate the same amount of heat.

But the payoff period for this size of furnace may not always be the same. Your 90% efficient furnace will cost you more than your 80% efficient furnace if you move to a new house within the payoff period. It is therefore recommended that you consider a number of factors such as your climate, how long you plan to own your home, and if rebates for a high-efficiency furnace are available.

Other things to consider

The factors that are noted above are certainly very important for a new furnace however there are other factors or differentiators among the many available products. Depending on where the furnace will be located, you may want to select a unit that is listed as quiet. Latest higher efficiency units may feature sealed combustion units which makes these quiet but multi-speed or 2-stage furnaces will be quieter compared to their counterparts since they can run at lower speeds. And of course, this can pay off for the warranty of the product. As long as you maintain your furnace appropriately you can expect a longer warranty which can translate to cost savings in the long run.

Choosing a Contractor

Along with selecting a furnace, another important thing is to choose a qualified, licensed contractor to install it. You should consider getting a quote or an estimate from at least three contractors before you make up your mind.
