Absolutely. Many older HVAC systems in the area are inefficient, working harder to heat or cool your home.

This upgrade, combined with proper installation, can significantly reduce energy consumption, directly addressing those frustratingly high bills and improving your home's comfort year-round.

Yes, it's a common issue we see. While the thermostat itself is electronic, it connects to your HVAC system through low-voltage wiring in your walls. Faulty, old, or improperly installed wiring during a previous HVAC installation can cause these persistent disconnects. Our HVAC and plumbing experts at Gateway Supply can diagnose the root cause—whether it's at the thermostat, the wiring, or the HVAC unit's control board—and perform the precise repair or replacement needed to restore reliable connectivity.

Your home's plumbing system plays a big role in efficiency. Hidden leaks from old water pipes or a faulty faucet can waste hundreds of gallons, indirectly driving up water heating costs. Our comprehensive plumbing inspection can identify these hidden issues. Furthermore, we offer gas line repair and installation to ensure your furnace, water heater, or stove is receiving fuel safely and efficiently, preventing energy loss and ensuring your appliances run at their peak performance.
