Top 8 Furnace Installation Mistakes You Can't Afford to Make

Best Owner Direct • September 25, 2024

At Best Owner Direct HVAC & Electrical, we know that furnace installation is one of the most critical home services when it comes to ensuring your family’s safety and comfort. But did you know that even a small mistake during installation could lead to bigger issues down the road? From fire hazards to inefficient heating, a poorly installed furnace is not something to take lightly. Let’s walk through eight common mistakes that can happen during furnace installation and why you should avoid them!

1. Hiring an Inexperienced Contractor

When you hire a contractor without the right experience or credentials, you’re gambling with your home’s safety. An unqualified technician may not follow necessary safety protocols, which could lead to gas leaks or system malfunctions. Always ensure your HVAC technician is licensed, certified, and insured.


2. Selecting the Wrong Size Furnace

Think bigger is better? Not when it comes to your furnace! A furnace that’s too big or too small for your home can lead to inefficient heating and higher energy bills. That’s why we always perform a load calculation to find the perfect size furnace for your home’s unique needs.


3. Poor Ductwork Design

Without properly designed and sealed ductwork, even the best furnace won't perform at its peak. Poor ductwork can lead to heat loss, inefficient heating, and even damage to your system. Make sure your contractor evaluates and addresses any ductwork issues during installation.


4. Failing to Meet Ventilation Requirements

One of the most critical safety issues is proper ventilation. Improper venting can cause dangerous carbon monoxide to build up in your home. All intake and exhaust vents must be installed correctly to ensure your furnace runs safely.


5. Incorrect Placement of the Furnace

Where you place your furnace matters more than you think. Installing a furnace in a poorly ventilated area or one that’s hard to access can lead to inefficiency and make it harder to perform regular maintenance. It’s best to place the furnace in an area with enough airflow and room for future repairs or inspections.


6. Incorrect Drain System Design

Did you know your furnace generates moisture? If not properly drained, it can lead to mold, water damage, or even freeze-ups in cold weather. A well-designed drainage system prevents these problems and keeps your furnace running smoothly.


7. Misplaced Thermostat

The thermostat controls the furnace, so it needs to be in the right spot! Placing the thermostat too close to heat sources or in drafty areas can lead to inaccurate temperature readings, leaving your home too hot or too cold. Make sure it’s installed in a central location for maximum comfort.


8. Forgetting to Register the Warranty

You’ve invested in a new furnace, so don’t forget to register the manufacturer’s warranty! Many homeowners skip this step, but it’s crucial for covering future repairs. Follow the manufacturer's guidelines to ensure you get the full benefit of your warranty.
