When it comes to home energy efficiency, most people think about windows, insulation, or even their HVAC system. But one of the biggest culprits behind high energy bills might be staring you right in the face, your garage door.
If your garage door isn’t properly sealed, insulated, or maintained, it can let outside air sneak in, making your home work harder to regulate temperature. Let’s break down why your garage door could be costing you more money every month – and what you can do to fix it.
1. Poor Insulation = Lost Energy
Garages are often one of the least insulated spaces in a home. If your garage door isn’t insulated, you’re essentially letting outside temperatures flow freely into your space. This is especially problematic if:
- Your garage is attached to your home.
- There’s a room above the garage.
- You use your garage as a workspace, gym, or storage area.
💡 Fix It: Upgrade to an insulated garage door to create a temperature barrier. Modern insulated doors help regulate temperature, keeping your garage warmer in the winter and cooler in the summer.
2. Air Leaks Around the Door
Even if your garage door is insulated, gaps and cracks around the door can let air in and out. This forces your home’s heating and cooling system to work overtime, driving up energy costs.
💡 Fix It:
✔ Check the weatherstripping along the sides and bottom of your garage door. If it’s cracked, worn, or missing, replace it.
✔ Inspect the door panels for damage or misalignment that might cause gaps.
✔ Consider adding a garage door threshold seal for extra protection.
3. An Old or Outdated Garage Door
Older garage doors were not built with energy efficiency in mind. If your door is 10+ years old, chances are it lacks proper insulation, has weakened seals, and is simply not as energy-efficient as newer models.
💡 Fix It: If your garage door is outdated, consider replacing it with an energy-efficient model that features polyurethane or polystyrene insulation. Not only will it help lower energy costs, but it can also boost curb appeal and home value.
4. Your Garage Door Opener is Working Overtime
If your garage door isn’t operating smoothly, your opener may be straining to lift and lower the door, using extra electricity in the process.
💡 Fix It:
✔ Lubricate moving parts (rollers, tracks, and springs) to keep everything running smoothly.
✔ Schedule garage door maintenance to check for worn-out components.
✔ Upgrade to a modern, energy-efficient garage door opener that uses less power.
5. Temperature Swings Affect Your Home’s HVAC System
If your garage is not insulated and connected to your house, the temperature fluctuations can seep into nearby rooms, making your HVAC system work harder to maintain a comfortable indoor climate.
💡 Fix It:
✔ Insulate your garage walls and ceiling if possible.
✔ Install an energy-efficient garage door to reduce heat transfer.
✔ Consider adding a smart thermostat that adjusts temperature settings based on garage conditions.
