Why Halden Heating and Air Marietta Is Kennesaw’s Preferred Furnace Repair Company
Andre Fuller founded Halden Heating and Air in 2004, and the standard he set then still drives how we operate in Kennesaw today. We are independently owned and operated under the Relay Home Co. network, and every job follows The Relay Visibility Guarantee: a written price before work begins, a live arrival time you can track, and photo documentation of what we found and fixed. That matters when it is 28 degrees outside and your furnace quit at 10 p.m.
Kennesaw homeowners keep calling us back because we do not hand over a vague four-hour window. You book, you see who is coming, and you watch the technician drive to your door. No price changes at the doorstep. No upsell pitch disguised as a safety lecture. If the repair fails within the guarantee window, we return at no charge. That is the 365-Day Done Right Promise, and it is written into every job we perform in Kennesaw.
Our technicians know the difference between a 1972 brick ranch off Cherokee Street and a 2006 two-story in Legacy Park. Both may call with the same symptom, but the fix is often very different. That local familiarity saves Kennesaw homeowners time and money because we are not guessing at what sits behind the access panel.
Styles & brands we work with
Emergency Furnace Repair in Kennesaw
Emergency Furnace Repair in Kennesaw means getting heat back on when the temperature drops below freezing and the house cannot hold warmth. Our crew handles these calls day and night, including holidays, and the first thing we do is get a written price to you before touching a single component. Most emergency furnace repairs in Kennesaw fall in the $150 – $700 range, though replacing a failed blower motor or heat exchanger lands at the upper end while an ignitor replacement or flame sensor cleaning sits lower.
No-Heat Calls in Freezing Weather
When a Kennesaw home loses heat during a cold snap, the priority is restoring warmth safely. We check for carbon monoxide, verify the limit switch is not tripping due to airflow problems, and diagnose the root cause rather than resetting the system and driving away. If your furnace is making a burning smell or the flame looks yellow, cut power at the thermostat and call (229) 514-0545 immediately.
Our 24/7 live phone support means a real person answers when you call about a cold house in Kennesaw. No answering service that promises a callback in the morning. The technician arrives with a live arrival time you can track, which matters even more when you are waiting in a cold living room.
Same-Visit Repairs Where Parts Allow
Many Kennesaw furnace breakdowns stem from failed ignitors, dirty flame sensors, bad capacitors, or clogged condensate lines. Our trucks carry these parts so we can typically finish the repair in one trip. If the part is unusual or model-specific, we order it with expedited delivery and keep you informed with a firm return date and the same written price.
Furnace Maintenance in Kennesaw
Furnace Maintenance in Kennesaw keeps heating equipment running efficiently from November through March, and it costs between $80 and $200 for a full inspection and cleaning. We recommend an annual tune-up before the first hard freeze, especially in homes with original 1970s furnaces near downtown Kennesaw or older subdivisions along Wade Green Road. A maintenance visit catches small failures before they become no-heat emergencies.
Heating Tune-Up With a Written Report
During a furnace tune-up in Kennesaw, we test gas pressure, inspect the heat exchanger for cracks, check the ignitor and flame sensor, measure temperature rise across the system, and clean the blower wheel and burners. You receive a written report showing exactly what we found and what the readings were. Our technicians are not paid on what they sell, so the report tells you what is actually needed and what can wait.
Pollen Season Airflow Service
Kennesaw’s spring pollen load is brutal on furnaces that also run the blower for air conditioning. Pollen builds up on blower wheels and clogs filters, which reduces airflow and causes the high-limit switch to trip. A spring maintenance visit after pollen season clears that buildup and keeps your furnace from overheating in the following winter. For heated homes with the system’s blower running year-round, filter replacement every 30 to 60 days during peak pollen is the difference between smooth operation and repeated shutdowns.
Trusted Brands We Service in Kennesaw
Our technicians are certified to repair furnaces from Trane, Lennox, Goodman, and Rheem, along with several other major manufacturers. We regularly stock ignitors, flame sensors, pressure switches, and blower motors for these brands on our trucks so Kennesaw homeowners are not waiting days for a part to ship. Whether your Kennesaw home runs a mid-2000s Goodman in a subdivision off Stilesboro Road or a Lennox unit in a newer development near McCollum Field, we have the training and local parts inventory to handle it.

AfterCommon Furnace Repair Problems We See in Kennesaw Homes
- High-limit switch tripping from undersized ductwork. In 1960s-70s ranch homes around downtown Kennesaw, original duct runs were sized for older, lower-efficiency furnaces. Newer high-efficiency units need more airflow, so the high-limit switch trips and the furnace shuts down. Our Furnace Repair team checks static pressure before replacing parts that may not be the real problem.
- Heat exchanger cracks in original 1970s furnaces. Mild Kennesaw winters with frequent temperature swings cause the metal in old heat exchangers to expand and contract, eventually cracking. A cracked heat exchanger poses a carbon monoxide risk. We inspect these on every tune-up in Kennesaw and provide a written finding.
- Flame rollout on exposed rural properties. Homes outside central Kennesaw with no wind shelter experience gusts that push down through the flue and disrupt the burner flame. This causes intermittent ignition failures and flame rollout errors on propane systems. A field-installed flue cap or different termination often solves it.
- Pollen-clogged blower wheels and filters. Kennesaw’s heavy spring pollen settles into the blower assembly and clogs filters rapidly. Restricted airflow makes the furnace overheat, even on mild days. In homes around Pine Mountain Road and similar tree-heavy streets, we recommend a post-pollen-season blower cleaning.

FAQs About Furnace Repair in Kennesaw
Older ranch homes in Kennesaw built during the 1960s and 70s typically have undersized ductwork by today’s standards. A newer furnace or even a replacement blower motor pushes more air than the ducts can handle, which raises static pressure and trips the high-limit switch. We measure static pressure during every Kennesaw repair and typically fix this by rebalancing ductwork, adding return capacity, or adjusting blower speed. Call (229) 514-0545 for a diagnosis that goes past the thermostat.
It can be safe if the ductwork is tested and, where necessary, modified first. Our techs recently worked on a 1970s brick ranch near downtown Kennesaw where a new blower motor was overheating because the original ducts created too much static pressure. We replaced the failing blower motor, added a capacitor, and rebalanced the ductwork to bring static pressure down to safe levels, which restored heat without a full system replacement. Every Kennesaw installation we handle includes a duct evaluation as part of the written quote.
Wind-driven downdrafts are the usual culprit on exposed rural properties around Kennesaw with no wind shelter. Gusts push down through the flue and disrupt the burner flame, triggering the rollout safety switch. The fix often involves a flue cap, a different termination, or repositioning the intake and exhaust pipes away from the prevailing wind. We inspect this during a service call and include the solution in the written price.
During Kennesaw’s peak pollen months from late March through May, we recommend checking and often changing the filter every 30 days. Pollen clogs filters fast here, especially in neighborhoods with heavy tree cover near Pine Mountain Road and similar streets. A clogged filter reduces airflow and makes the furnace overheat, so a $10 filter change prevents a $400 repair. The furnace maintenance visit includes a filter inspection, and we will tell you exactly what schedule your home needs.
The answer is usually efficiency loss from age, dirty burners, or duct leakage, not a broken furnace. A 1970s furnace runs at roughly 60-70% AFUE (annual fuel utilization efficiency), meaning 30 to 40 cents of every dollar in gas is wasted. Cracks or gaps in aging ductwork in a Kennesaw ranch home push that waste higher. We can measure your system’s performance during a maintenance visit and show you the numbers so you can decide whether repair or replacement makes sense without sales pressure.
