Hanna Heating & Cooling - Tucson's Qualified HVAC Repair

In Tucson, Wi-Fi signal interference from thick stucco walls, distance from your router, or even power surges from our monsoon storms can disrupt smart thermostat connections. At Hanna Heating & Cooling, we diagnose the specific cause—whether it's a wiring issue, a needed C-wire installation, or simple repositioning—to ensure your thermostat reliably manages your cooling system and saves you money.

Absolutely. In our intense desert heat, leaky ducts can force your AC to work up to 30% harder, wasting cooled air into your attic or crawlspace. This drastically reduces efficiency and spikes your energy bills. Our technicians perform comprehensive duct inspections using specialized tools to locate leaks and seal them properly, ensuring all that expensive cool air gets delivered into your living spaces.

Our professional duct sealing starts with a thorough inspection of your accessible ductwork. We then use industry-approved mastics, specialized tapes, or aerosol-based sealants to permanently seal leaks at joints and seams. For Tucson homes, we pay special attention to ducts in hot attics, where leaks are most costly. This service improves airflow, enhances comfort in every room, and increases the overall efficiency and lifespan of your HVAC system.
