Heating repair in Kennesaw covers more than furnaces. Homes here run gas furnaces, electric furnaces, heat pumps, and heat-strip backup, and each fails differently in our ice-storm winters. Our licensed technicians diagnose the actual system you have, show you the reading behind the diagnosis, and give you a written price before any chargeable work begins.
When the heat quits during a freeze, a vulnerable resident or frozen pipes make it urgent — so we answer the phone 24/7 and run priority dispatch during cold snaps across Kennesaw and Cobb County. Most repairs are finished the same visit because we stock the common parts on the truck.

Signs your heating system needs repair
Call us if you notice any of these — several together usually means don't wait:
- No heat at all, or air blowing but never warm
- The system short-cycles — turning on and off every few minutes
- Weak or uneven heat, with some rooms far colder than others
- Burning, musty, or electrical smells when the heat runs
- Loud banging, rattling, or clicking at startup
- A heat pump that ices over and won't defrost
- Heating bills climbing with no change in use
How our heating repair visit works
You'll know the arrival window, the diagnostic fee, and the repair price before we start.
- 1
Safe triage & arrival
We confirm the window and diagnostic charge, then check the thermostat, power, and any safety concern like a gas smell or electrical odor first.
- 2
Full-system diagnosis
We test ignition, flame sensor, heat exchanger, controls, airflow, and — on heat pumps — the reversing valve and defrost cycle, instead of swapping parts on a hunch.
- 3
Written options & your approval
We explain the diagnosis in plain English, show you the reading, and give you written repair options. Nothing chargeable happens until you approve the price.
- 4
Repair, test & clean up
We complete the approved repair, verify safe operation and a proper temperature rise, and document the parts and readings.
Every heat source we repair
Because "heating" means different equipment in different homes, we repair all of it. For gas and electric furnaces, see our dedicated furnace repair page. For heat pumps that heat and cool, our heat pump service covers reversing-valve and defrost problems. And when the heat is out during a freeze, our 24/7 emergency furnace repair runs priority dispatch.
Whatever you have, we diagnose the real cause first — a no-heat call can be a failed igniter, a tripped safety, a bad control board, a clogged flame sensor, a reversing-valve fault, or a simple thermostat issue, and they are not interchangeable.
Why North Georgia heating systems fail
Our heating season is short but sharp. Systems sit mostly idle through the fall, then get asked to run hard during the first freeze or an ice storm — and that's exactly when weak igniters, dirty flame sensors, and marginal capacitors give out. Heat pumps that work fine in mild weather can ice over and struggle to defrost when temperatures drop into the 20s.
A fall heating check catches most of these before they strand you. If yours was skipped and the heat quits, call — we keep the common parts stocked so most repairs finish the same visit.
What heating repair costs in Kennesaw
Published Atlanta-area research puts most furnace and heating repairs around $130–$650, depending on the part. These are context ranges, not a quote — a flame sensor is far cheaper than a control board or heat exchanger.
We publish our diagnostic policy up front and tell you whether it applies toward the repair, so you're never guessing at the final number.
What affects your price:
- The failed component — igniter and sensors are inexpensive; control boards and heat exchangers are not
- System type — gas furnace, electric furnace, or heat pump
- Whether the fault is isolated or part of an aging, repeat-failure system
- Accessibility of the equipment (attic, crawl space, tight closet)
- Emergency or after-hours timing during a freeze
