Common Mistakes to Avoid During Furnace Installation


Installing a furnace is a complex job requiring a skilled professional’s expertise. However, novice homeowners and DIY enthusiasts can make costly mistakes when attempting furnace installation. It’s essential to avoid these common pitfalls to ensure your furnace is installed properly, efficiently, and safely.

  1. Ignoring Furnace Specifications: One of the most common mistakes people make when installing a furnace is ignoring the manufacturer’s specifications. It can be tempting to substitute components for cheaper alternatives or skimp on installation materials, but this can lead to costly repairs and potential safety risks in the future. Always follow manufacturer instructions precisely to ensure your furnace works correctly and safely.
  2. Incorrectly Sizing the Furnace: Incorrectly sizing your furnace can lead to significant problems. If your system is too large, you may not get optimal efficiency and be at risk of short cycling, where the furnace frequently turns off and on. On the other hand, if your system is too small, you won’t be able to heat all areas of your home adequately or could experience frequent repairs due to the strain of overworking. Ensure you purchase and install a properly sized furnace for your home.
  3. Failing to Change Air Filters: Many people forget to change their air filters after installation, leading to clogging and inefficient operation. Over time, dust, dirt, pet dander, and other particles can collect in the filter, reducing airflow. Change your air filters every three months to maximize efficiency and help extend the life of your furnace.
  4. Poor Ventilation: Improper ventilation is a major issue when installing furnaces. If the exhaust vents are not connected correctly or installed in an incorrect location, it can lead to dangerous gases building up in the home. Ensure all vents are connected and installed in the proper location according to manufacturer instructions.
  5. Neglecting Maintenance: Installing a furnace is just the beginning of the process. To keep your system running efficiently, you must regularly perform maintenance tasks such as inspecting air filters and cleaning burners. Neglecting these duties can lead to costly repairs or even replacement.
  6. Forgetting to Activate Carbon Monoxide Detectors: Carbon monoxide is a dangerous gas that’s released from furnaces when they’re operating. Install carbon monoxide detectors in your home and test them regularly.
  7. Not Performing a Final Safety Check: Always perform a furnace safety check after installation. This includes checking all connections and wiring, inspecting thermocouples and gas valves, and ensuring ventilation systems are connected correctly.

Furnace installation is not a job to take lightly. Follow all manufacturer instructions and use the proper materials for maximum efficiency, safety, and longevity. You can get the most out of your furnace system with careful installation and regular maintenance. To ensure you install your furnace correctly, it’s best to work with an experienced professional who can identify potential problems and help you avoid costly mistakes.
