Simple Process

How It Works

  1. Call us any hour of the day or night — our furnace emergency line dispatches a licensed heating technician within 2–4 hours, 365 days a year, because a heating failure in winter is never a 9-to-5 problem.

  2. The technician inspects the igniter, flame sensor, heat exchanger, pressure switches, and gas valve using combustion analysis tools to pinpoint the root cause — not just mask the symptom.

  3. Most furnace repairs are completed on the first visit with parts from our stocked truck; we also perform a CO safety check and leave you with a written inspection report for your records.

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.

Gas furnace repair is not a service category where technician quality is interchangeable. Work done incorrectly on a gas appliance — incorrect gas pressure, improper heat exchanger diagnosis, incorrect flue pipe reassembly — can create carbon monoxide hazards that injure or kill families. Summit Climate Solutions requires NATE certification on all furnace technicians, maintains current licensing in every state we operate in, carries gas work endorsements where required, and includes a free carbon monoxide safety check on every furnace visit — not because it's required, but because it's the right thing to do. Our 20-year track record across six major metros represents thousands of gas appliance repairs performed safely and documented thoroughly. We earn trust by doing the work right, every time.

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

  1. Improper gas pressure adjustment by an unqualified technician creates incomplete combustion and CO poisoning risk

  2. Incorrect flue pipe reassembly after furnace service can allow CO to enter the living space silently

  3. Furnace work in most states requires a gas work endorsement in addition to a general HVAC license

  4. Misdiagnosed heat exchanger conditions — missed cracks or falsely condemned good exchangers — are both dangerous mistakes

  5. Without a post-repair CO test, there is no verification that the furnace is operating safely after service

  6. 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.

  7. 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.

  8. 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

10 answered
What credentials should a furnace repair technician have?

At minimum: current state HVAC contractor license (or technician license depending on state structure), EPA 608 certification for refrigerant handling if applicable, gas work endorsement where required by state law, and liability insurance plus workers' compensation coverage. NATE certification in gas heating is the industry's verified competency standard above the legal minimum. Summit technicians hold all applicable credentials for every state we operate in.

Why is a carbon monoxide check included with every furnace repair?

Any furnace repair involves opening the combustion chamber, removing and reinstalling the heat exchanger access panels, potentially adjusting burner assemblies or gas pressure, and disturbing flue pipe connections. Each of these actions creates opportunity for CO to escape the flue gas circuit if not done correctly. We perform a post-repair CO check at the registers and near the unit with a calibrated CO meter as a quality assurance step before we leave. If CO is detected, we don't leave until the source is found and corrected.

How do I know the furnace repair will last and not fail again next winter?

We warrant all parts and labor for 1 year in writing. Parts used are OEM or OEM-equivalent rated for the application — we document part numbers on the repair invoice. The technician verifies correct operation after repair through combustion analysis, safety control testing, and operating cycle observation. If the same component fails within 12 months, we return at no charge. Our callback rate within 90 days of a furnace repair is under 3%.

Can I see the technician's credentials before they begin work?

Yes, and we encourage this. Our technicians carry their license cards and NATE certification cards. You can also verify our company license through your state licensing board online using our license number, which is on every written estimate. We consider credential transparency to be a basic professional obligation, and any technician who resists showing credentials should not be working on your gas appliances.

What does Summit's 20-year track record mean for furnace repair quality?

Twenty years of residential furnace service across six major metros means we've seen essentially every failure mode on every major brand and system age. Our technician training is informed by real-world call history — what fails on Carrier furnaces after 12 years in humid climates, what distinguishes a legitimate heat exchanger crack from surface oxidation that alarms a less experienced tech. That institutional knowledge produces faster, more accurate diagnoses and fewer unnecessary repeat calls.

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.

How long does furnace repair typically take?

Most repairs — igniter replacements, flame sensor cleanings, pressure switch fixes — take 1–2 hours. Circuit board or inducer motor jobs may run 2–3 hours. We stock the most common parts so the majority of repairs are completed in one visit.

What causes a furnace to short cycle?

Short cycling (rapid on/off) is usually caused by an overheating heat exchanger triggered by a clogged filter, blocked vents, or a failing blower motor. It can also indicate a cracked heat exchanger, which is a carbon monoxide risk. Do not ignore short cycling — call us for a diagnostic.

How do I know if I should repair or replace my furnace?

Consider replacement if the repair cost exceeds 50% of a new unit's price, the furnace is over 15 years old, or you are facing recurring breakdowns. We will give you an honest repair-vs-replace comparison with energy savings projections — no high-pressure sales tactics.

Do you service oil furnaces as well as gas furnaces?

Yes. Our technicians are certified to service gas, oil, and electric furnaces. Oil furnace calls may include nozzle cleaning, oil filter replacement, and combustion efficiency testing as part of the diagnostic.
