Furnace and heat pump repair in Nolensville

Typical heating problems in newer homes

What we see most:

• Furnace lockout. After several failed ignition attempts the furnace stops. Often a flame sensor, ignitor or gas supply issue.
• Heat pump not keeping up. Low charge, a failing defrost board or backup heat that is not engaging.
• Thermostat communication errors. Smart and zoned systems rely on wiring and settings that must match the equipment.
• Uneven heat between floors. Airflow and duct issues, particularly with bonus rooms.
• Short cycling. Dirty filters, sensors or an oversized furnace.

Dual-fuel and multi-stage systems

Many newer homes use two-stage furnaces, variable-speed blowers or dual-fuel systems that switch between heat pump and gas. These are efficient and comfortable, and they are also more complex to diagnose. We test each stage and the controls that tell them when to run.

Safety and warranty

If you smell gas, leave and call your gas utility and 911. If your equipment is relatively new, part of a repair may be covered by the manufacturer or installer. We tell you what we find so you can ask the right questions.

Zoning and smart thermostat faults

Zoned systems add dampers, control boards and several thermostats. When one zone will not heat, the cause may be a stuck damper, a miswired sensor or a thermostat that lost its settings. We check each part of the chain so you are not replacing a furnace that works fine.

Quick checks before you call

In a zoned home, note whether one thermostat or all of them are calling for heat, and whether any zone does heat. That narrows the problem fast. Also check the filter, the power switch at the furnace and any blinking control-board codes, and mention them when you call.
