A furnace is an essential part of any home, and it is vital to have a working one in the colder months. Furnace installation is a big task and should not be attempted by a novice. Learning how to install a new furnace is something that every homeowner should do, as it can save you a lot of money on installation costs.
It might be a significant job that is best left to the professionals. However, knowing how it works and what is involved in the installation process is essential.
Before attempting this project, ensure you have all the necessary tools and know how to work with gas safely. We will discuss the tools and materials you need and the steps involved in furnace installation.
Choose the Right Furnace
There are two types of furnaces: electric and gas. Gas furnaces are more typical, but electric furnaces can be a good choice if you don’t have access to natural gas. You’ll also need to decide whether you want a single-stage, two-stage, or modulating furnace.
Single-stage furnaces are the most common and least expensive, while two-stage furnaces provide better temperature control and are more efficient. Modulating furnaces offer the best temperature control and are the most efficient and expensive.
Look for the Suitable Location
Once you have chosen the right furnace, you’ll need to find a good location. The location should be in a well-ventilated area and out of any foot traffic. Choosing a place close to an exterior wall is also essential to run the venting pipes through it.
Prepare the Area
Once you have chosen the location, you’ll need to prepare it for installation. It means clearing out debris and ensuring the area is level. You should also make sure that there is enough space around the furnace for air to circulate.
Determine the Location of the Drain and Duct
The next step is to determine the location of the drain and the ductwork. You need to connect the drain to a sewer line and the ductwork to your home’s vents.
The heating system’s return air duct may be located at the bottom or side. Create a hole for the return air duct in the system. On the new furnace, look for the location that has been marked. Place the furnace appropriately after determining which direction to run the condensate drain. The furnace must slant slightly toward the condensate drain’s outlet.
Attach the Vent Pipes
The next step is to attach the vent pipes to the furnace. The pipes should be made of metal and at least four inches in diameter. There are two types of vent pipes: B-vent and direct vent.
B-vent pipes are typically used for gas furnaces, while direct vent pipes can be used for either gas or electric furnaces.
Ensure the Condensation Drain Connection
You’ll need to ensure that the condensation drain connection is secure. You can do it by sealing the connection with caulk or by using a screw-type clamp.
Test the New Furnace
After installing the furnace, you’ll need to test it to ensure it’s working correctly. First, turn on the power to the furnace. Then, set the thermostat to its lowest setting and wait for the furnace to come on.
Once the furnace is on, raise the thermostat setting until the furnace turns off. It will help you to determine the furnace’s heating capacity.
If you’re satisfied with the performance of the new furnace, you can now enjoy its warmth and comfort.
Installing a new furnace can be a big job, but it’s one that you can do yourself if you’re handy and have the right tools. Following the steps outlined above can ensure that you can install your new furnace correctly and safely. If it is challenging, you can also consult a professional for help.
