A thermostat connected to your furnace does more than set the temperature. it controls gas valves, the ignition sequence, safety switches, and the blower. Incorrect wiring can prevent the furnace from operating, cause the fan to run constantly, or in worst cases, create safety issues with gas control. We've fixed thermostat wiring mistakes in Bowie homes that left furnaces running their blower nonstop for weeks. Pentagon Air installs furnace thermostats with the wiring knowledge to get every connection right.
When You Need Furnace Thermostat Installation
Install a new furnace thermostat if your current one doesn't control your heating correctly, if you're upgrading from a manual model to a programmable or smart unit, or if your furnace was recently replaced and needs a compatible thermostat. If your furnace short cycles, runs the fan without heating, or ignores temperature settings, the thermostat wiring may be wrong or the thermostat itself may need replacing.
