No two heating systems break the same way, and in Iowa City 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 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.
When to Call for Heating Repair in Iowa City
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- The thermostat calls for heat but the vents blow cold air or nothing
- The system starting and stopping every few minutes without warming the house
- Cold rooms in one part of the house while others are comfortable
- A heat pump's outdoor unit encased in frost or ice
- Booming or banging at ignition, a sign of delayed burner light-off
- Strange smells from the vents, especially rotten egg or burning
- Clicking and failed ignition attempts before the furnace gives up
- Energy costs climbing even though the house feels colder
Early Action Saves Money
