When you install a new furnace, it's not simply a manner of unplugging the old one and plugging in a new one. Your home needs to be able to support it. Here's what you should check.
Electrical Voltage
Even gas-powered furnaces typically use some electricity to help them get started. Most furnaces require a high-voltage outlet rather than a standard outlet. In addition, there are different levels of voltage in high-voltage outlets, and they aren't interchangeable. You may need to run a new outlet before installing your furnace.
Fuel Type
Are you buying a natural gas, oil, or propane furnace? Do you want to switch? The thing to remember here is that natural gas, oil, and propane all use different kinds of tanks and pipes. You can't just disconnect your original furnace and hook up a new one if you want to change your fuel type. You'll need to replace the tank and run new pipes.
This can still make sense depending on energy prices and availability in your area. If you have an old oil furnace and everyone in your city has switched to natural gas, it can be much cheaper over the long run to change out your pipes and tanks for a new natural gas furnace.
Duct Size
When you were looking at new furnaces, your HVAC contractor probably helped you calculate what size of furnace to get for efficient and even cooling. But what happens if your current furnace was too small or too big? You may have a problem with your ducts.
Your ducts are sized for the amount of air coming out of your furnace. If they're too small, they may choke the airflow, while if they're too big, the furnace might not be able to push air through them. If you change to a different size of furnace, you may need to change out your ducts as well.
Building Codes
You should also be aware of the building codes in your area. First, do you need to get a permit for your furnace installation work? Second, are you allowed to make the changes you want?
Many older homes aren't up to current building codes but are grandfathered in. However, if you make changes to part of your HVAC system, you may have to do additional work to bring your entire system up to the current code.
