Lund Mechancial - Reno's Trusted HVAC Repair

Smart thermostat issues are common here and often stem from compatibility, incorrect wiring, or Wi-Fi connectivity problems with your specific furnace or heat pump. Our technicians are trained to diagnose the root cause—whether it's a setup error, a firmware update needed, or a wiring issue—and get your smart thermostat communicating properly with your system to restore efficient, automated comfort.

If your heat pump is stuck in one mode (only heating or only cooling regardless of the setting), isn't reaching the desired temperature, or you hear a hissing noise, the reversing valve may be failing. This critical component switches your system between heating and cooling. We'll test the valve and electrical controls to determine if a repair or replacement is needed to restore your system's full function.

Yes, absolutely. Our technicians are experienced with the wide variety of HVAC brands and models installed in the Reno area. Whether you have a newer high-efficiency system, an older unit, a heat pump, or a conventional furnace and AC, we have the expertise to troubleshoot, repair, and maintain it effectively, ensuring reliable performance for our local climate.
