If you’re considering installing a furnace yourself, it’s important to weigh the risks and potential benefits. It may be more economical to hire a professional in the long run, especially if you’re not confident in your abilities or don’t have the necessary tools. However, if you’re determined to install the furnace yourself, you should follow these steps:
1. Gather the necessary tools and materials.
Before you begin, you’ll need to gather all of the necessary tools and materials. This includes:
- A new furnace: Choose a furnace that’s the right size for your home.

5. Connect the electrical wiring.
Wiring the furnace to your home’s electrical system requires a good understanding of electrical codes and safety procedures. You’ll need to run a separate electrical line to the furnace. If you’re not comfortable working with electricity, it’s best to call a professional electrician.
6. Test the furnace.
Once you’ve finished installing the furnace, test it to make sure it’s working properly. Check for leaks, listen for unusual noises, and ensure that the heating system is functioning efficiently.
7. Check for safety hazards.
After the initial testing phase, you should thoroughly check for any potential safety hazards. This involves inspecting for gas leaks, faulty electrical connections, and any other issues that could cause problems.
8. Get a professional inspection.
Even if you have successfully completed the installation yourself, it’s essential to have a qualified HVAC technician inspect your work and ensure everything is installed correctly and safely. This is crucial for your safety and could potentially prevent any costly repairs down the road.
While how to install a furnace without calling a professional might seem like a cost-saving option, it can be a risky endeavor. If you don’t have the necessary knowledge and experience, you could end up causing more harm than good. It’s generally recommended to consult with a professional HVAC contractor for furnace installation.
