Heating Systems We Repair
Most Northshore homes heat with either a gas furnace or a heat pump, and many newer homes use a dual-fuel setup that combines both. We repair them all:
- Gas furnaces: ignition, flame sensor, gas valve, blower, and heat exchanger problems. See our dedicated furnace repair page for details.
- Heat pumps: refrigerant leaks, reversing valves, defrost controls, capacitors, and compressors
- Electric furnaces and air handlers: heat strips, sequencers, relays, and blower motors
- Dual-fuel systems: controls that switch between heat pump and gas backup
- Ductless mini-splits in heating mode, through our mini-split repair service
- Geothermal heat pumps and the loop and pump components that support them
- Thermostats and the wiring that tells your system when to run
Signs Your Heater Needs Repair
Small problems get bigger the longer they run. Call for service if you notice any of these:
- The system won’t turn on, or it starts and shuts off without heating
- Weak or uneven heat, with some rooms warm and others cold
- Cool or lukewarm air from the vents when the thermostat calls for heat
- Banging, squealing, grinding, or rattling from the furnace, air handler, or outdoor unit
- An outdoor heat pump unit that stays coated in ice
- The “aux” or “emergency heat” light staying on in mild weather
- A burning smell that lingers past the first few minutes of the season
- Energy bills that spike even though your usage hasn’t changed
If you smell gas or your carbon monoxide alarm sounds, leave the home right away and call for help from outside.
