No two heating systems break the same way, and in Nashua homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often stall on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve traps the system in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
The repair homeowners call us about most is Furnace Repair. If something has stopped working, start there.
Signs You Need Heating Repair in Nashua
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- Strange smells from the vents, especially rotten egg or burning
- Uneven heat, with certain rooms that never warm up
- Thick ice or frost covering the heat pump outside
- Higher heating bills with less comfort to show for them
- Frequent on-off cycles that never bring rooms up to temperature
- The thermostat calls for heat but the vents blow cold air or nothing
- A loud boom when the burners light, which points to delayed ignition
- The furnace clicking and trying to light but shutting back down
