Do you have an old furnace that's reached the end of its useful life? Is it time for a new furnace? While new heating installation can be costly, it's usually a wise investment, especially in colder climates. Your new furnace will likely be significantly more efficient than your old one, so you'll probably recoup your installation costs with lower utility bills. Also, if you're in a cold area and your old furnace is completely broken, you may not have much choice but to install a new one. Not all furnaces are the same though. Here are a few things you need to consider before your heating installation:
Bigger isn't always better. A furnace that is too small is clearly a problem because it won't be big enough to heat your entire house. To avoid this problem, many homeowners will buy oversized furnaces. That's not good either, though. A unit that is too big will heat the home quickly and then shut off. When the house cools, it will turn on and rapidly heat the home again. This quick on-off cycle is tough on the furnace and it erodes the unit's efficiency, possibly eliminating any utility savings you may have achieved.
To make sure you get the right size unit, work with a heating contractor that uses the Manual J method. This method considers a number of factors, including home size, climate, and duct design, to determine the right size unit for your home.
Higher efficiency means smaller unit. No furnaces are 100 percent efficient. There will always be some loss of energy in the heat transfer from the furnace to the vents in your home. However, some furnaces are much more efficient than others. There's a direct relationship between the efficiency of your unit and the size of furnace that you need. The higher the efficiency, the more heat that will reach your home, so the smaller size you need. With a less efficient unit, less heat will reach your vents, so you'll need a bigger unit to make up for that.
Check your ducts too. If your furnace has been in place for a long time, it's likely that your ducts haven't been checked since they were first installed. Over time, the joints between duct sections can become loose, creating small gaps where air can escape. That air leakage is a drain on your home's efficiency. If you're having your furnace replaced, that's probably a good time to have your ducts checked out as well. Your contractor can tighten gaps and replace any sections that have deteriorated.
