“Pollen had our outdoor unit so clogged it was barely cooling in Marietta. Summit cleaned it, found a low refrigerant issue from a slow leak, and fixed both. Night and day difference in cooling.”
“Heat pump install in Alpharetta — perfect for Atlanta's climate. Heats and cools efficiently without a gas line. Summit handled the whole project including the new thermostat setup.”
“Our Roswell home is 30 years old with original ductwork. Summit sealed the ducts, added returns to two rooms, and our AC actually reaches the back bedrooms now. Should have done this years ago.”
Our Approach
Furnace Repair in Atlanta
Atlanta's long, humid summers make AC the most-used system in the home — pollen season also clogs outdoor condenser units faster than almost anywhere in the country, and the shift toward heat pumps in this moderate climate zone means installation expertise matters more than ever.
Furnace repair in Atlanta occupies a genuine but compressed heating window. While the metro area — including Marietta, Alpharetta, and Roswell — is known for its long warm season, average winter temperatures drop into the 30s and 40s from December through February, with occasional ice storms and periods of sustained cold that push furnaces to maintain comfortable interior temperatures through nights that can dip into the teens. Atlanta's heating demand is real, even if it's shorter and less intense than Chicago or Denver. The Atlanta housing stock's shift toward heat pumps — accelerating over the past decade as new construction increasingly chooses all-electric systems appropriate for the moderate climate — creates a furnace repair landscape that is increasingly focused on heat pump reversing valve failures, defrost cycle issues, and auxiliary heat strip problems rather than traditional gas furnace repairs. Summit Climate Solutions technicians in the Marietta and Alpharetta markets are thoroughly trained on heat pump system diagnostics, including the nuanced interpretation of reversing valve behavior, defrost board cycling, and the relationship between ambient temperature and heat pump capacity in Atlanta's climate zone. For homes with traditional gas furnaces — still common in older Roswell and Marietta neighborhoods built before the heat pump transition — the dominant repair needs are similar to other Southern markets: igniter and flame sensor failures from long off-season dormancy, pressure switch failures from inducer motor wear, and control board faults from the aging electronics of 15–25 year old systems. Atlanta's mild winters mean furnaces may go 5–7 months between operating seasons, and the components most vulnerable to dormancy — flame sensors accumulating oxide, igniter elements developing stress fractures — need inspection every fall before the heating season demands reliable performance. Ice storms are a specific Atlanta challenge for both heat pump and gas furnace systems. When Atlanta experiences an ice event — which happens several times each winter with enough severity to disrupt normal operations — outdoor heat pump units can accumulate ice beyond what the normal defrost cycle can remove, particularly if the defrost board or reversing valve isn't functioning optimally. Summit technicians are familiar with the manual defrost procedures and defrost system diagnoses required to restore heat pump operation during and after Atlanta ice events.
Furnace emergencies carry risks that go beyond discomfort. A cracked heat exchanger can allow carbon monoxide — an odorless, colorless gas — to circulate through your home's ductwork while the system appears to run normally. A failed igniter in sub-zero weather can drop interior temperatures dangerously fast, particularly for households with elderly residents, infants, or pets. Summit Climate Solutions technicians respond to furnace emergencies 24/7 and include a free carbon monoxide safety check with every repair visit. We carry replacement igniters, flame sensors, gas valves, inducer motor assemblies, and control boards on every truck. Our technicians are NATE-certified and trained to diagnose both the immediate failure and any secondary safety concerns before they become tragedies.
Every furnace repair includes a complimentary carbon monoxide safety check with a calibrated detector — because a cracked heat exchanger can endanger your family even after the heat comes back on.
Problems We Solve
-
Cracked heat exchangers allow carbon monoxide to enter the air supply without triggering immediate alarms
-
Failed igniters in below-freezing conditions cause interior temps to drop to dangerous levels within hours
-
Rollout switches and pressure switch failures can disable the furnace entirely and require expert diagnosis
-
Gas valve faults and blocked flue pipes create explosion and CO poisoning risk if bypassed by an unqualified tech
-
Polar vortex events and cold snaps create 3–5 day waits with most HVAC companies — maintenance plan customers jump the queue
-
A furnace that will not ignite on a freezing night puts your family at risk of dangerously low indoor temperatures — pipes can freeze within hours in extreme cold, multiplying the cost of the emergency.
-
Short cycling — your furnace turning on and off every few minutes — stresses the heat exchanger and blower motor, and often signals a cracked heat exchanger that can leak carbon monoxide into your living space.
-
A yellow or flickering burner flame instead of a steady blue one is a carbon monoxide warning sign that demands immediate shutdown and professional inspection before the furnace is operated again.

Frequently Asked Questions
What should I do while waiting for the emergency furnace technician to arrive?
If you suspect a gas leak or smell rotten eggs, evacuate immediately and call your gas utility before calling us. If the issue is simply no heat, close interior doors to conserve warmth in occupied rooms, use electric space heaters away from flammable materials, and call us immediately. Do not attempt to bypass safety switches — furnaces shut themselves off for a reason.
What does the free carbon monoxide safety check include?
Our technician performs a combustion analysis to measure CO concentration in flue gases, inspects the heat exchanger for visible cracks or corrosion using a camera probe, tests the CO detector in the living space, and checks the flue pipe for blockages or backdrafting. This check is included at no charge with every furnace repair visit — not just emergencies.
My furnace is running but blowing cold air — what's wrong?
Cold airflow with the blower running usually points to a failed igniter or flame sensor, a faulty gas valve that isn't opening, a tripped rollout or high-limit switch caused by overheating, or a cracked heat exchanger that has triggered a safety lockout. All of these are diagnosable on-site. Do not reset the system repeatedly — repeated lockout cycles can mask dangerous conditions.
How do I know if my furnace needs emergency repair vs. a standard service call?
Schedule emergency service if: the system is completely non-functional in freezing temperatures, you smell gas or burning near the unit, your CO detector has alarmed, the furnace is making loud banging or screeching sounds, or interior temps are dropping rapidly. For warm-weather soft failures or minor efficiency concerns, a standard next-day appointment is appropriate.
Can a furnace be repaired same-day, or will parts need to be ordered?
The majority of furnace failures — igniter replacement, flame sensor cleaning, pressure switch swap, inducer motor swap, control board replacement — can be resolved same-day because we stock high-frequency parts on every truck. Unusual OEM-specific parts may require next-morning sourcing. We will always give you a clear timeline before leaving your home.
My furnace stopped working at 2 AM — do you offer after-hours emergency repairs?
Yes. Our emergency heating line operates 24 hours a day, 7 days a week, 365 days a year. After-hours calls carry a transparent premium of $50–$75 over daytime rates. We will tell you the full cost before we dispatch anyone.
Is a yellow furnace flame dangerous?
Yes. A healthy furnace flame is blue. A yellow, flickering, or split flame indicates incomplete combustion and a possible carbon monoxide leak. Shut the furnace off at the thermostat, open windows, evacuate the house, and call us immediately for an emergency safety inspection.
Can I run a space heater safely while waiting for furnace repair?
A single 1,500W space heater can safely supplement heat in one room. Never use gas stoves, ovens, or unvented propane heaters to heat your home — these produce carbon monoxide. Keep the space heater away from flammable materials and never leave it unattended while sleeping.
