No two heating systems break the same way, and in Portsmouth homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often quit 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 underperforms 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.
When to Call for Heating Repair in Portsmouth
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- Heating bills spiking while comfort keeps falling
- A furnace that tries to light, clicks, and then quits
- A loud boom when the burners light, which points to delayed ignition
- No warm air at the registers even with the heat turned up
- Uneven heat, with certain rooms that never warm up
- The system starting and stopping every few minutes without warming the house
- A rotten-egg, burning, or musty smell once the heat kicks on
- Thick ice or frost covering the heat pump outside
