HVAC in Roswell, GA | One Hour Heating & Air

Roswell homeowners call One Hour Heating & Air Conditioning of North Atlanta for HVAC repair, installation, retrofit work, and maintenance across the city’s full housing era range, from pre 1900 historic district homes around Canton Street to 1970s and 1980s subdivision stock in Martin’s Landing and Brookfield West. We hold Georgia HVAC license GAREGCN2011384 (Class I/II Conditioned Air Contractor), dispatch from Alpharetta 12 minutes north via GA 400, and stand behind every job with our “Always On Time…Or You Don’t Pay A Dime!®” guarantee and a 100% Satisfaction Guarantee for two years. NATE certification 1023518, EPA 608 Universal certified (certification number PFWXHNZ4MT), factory authorized on Daikin, Trane, Rheem, and Carrier.

Most HVAC work in Roswell is retrofit work: original 1970s and 1980s attic ductwork commonly leaks 20 to 30%, basement installed gas furnaces from the 1980s are at or past their 20 year service life, and historic district homes around Canton Street were originally built without central air at all. Whether you’re in a 1972 Martin’s Landing ranch with original ductwork or a restored 1920s home off Canton Street where the system was retrofitted in stages, the diagnostic questions are different from a typical new build call. We work that way.

Why Roswell Homeowners Call One Hour

The Roswell housing era spread means a single price list and a single playbook don’t work. Diagnosing a furnace failure in a 1985 Brookfield West basement is different work from quoting a heat pump retrofit on a 1920s Canton Street home with no existing ductwork. We dispatch experienced techs who’ve worked across that range:

  • Older home retrofit knowledge. We’ve quoted, installed, and serviced systems in Roswell’s 1960s through 1980s subdivisions and historic district enough times to know where the constraints typically are: attic ductwork access, basement furnace clearances, electrical service capacity for heat pump conversions, and structural questions in pre 1940 homes.

  • Familiarity with Roswell’s water utility and code authority. Roswell operates its own water treatment plant (Big Creek source) blended with Atlanta Fulton, and the city is its own permit and code authority for HVAC work, which affects timeline and process compared to unincorporated Fulton or DeKalb work [VERIFY: confirm Roswell HVAC permit specifics with city].

  • Honest assessment of ductwork condition. Most Roswell homes built before 1990 have ductwork that’s a bigger source of inefficiency than the equipment itself. We measure it, we tell you whether sealing, partial replacement, or full replacement is the right answer, and we don’t quote a new system without addressing the ducts that will feed it.

  • 24/7 dispatch with no after hours surcharge. Same flat rate at 2 AM in January as 2 PM in May.

Top HVAC Services We Provide in Roswell

AC Repair in Roswell

The most common Roswell AC failures cluster around aging refrigerant lines in retrofitted systems, condensate drain backups during pollen heavy spring, and capacitor or contactor failures on equipment that’s been running 12+ years.

AC Installation in Roswell

Like for like AC replacement on a 1970s Martin’s Landing home often delivers less efficiency gain than the equipment spec suggests, because the existing ductwork is leaking the savings into the attic. We diagnose duct condition first, then size the equipment to the actual delivered load.

Heat Pump Installation in Roswell

Older Roswell homes with separate gas furnace + AC pairs are some of the best heat pump conversion candidates in North Fulton, especially where the gas furnace is also approaching end of life. Georgia GEFA’s HEAR program (energyrebates.georgia.gov) is income capped at 150% AMI but covers electrification, replacing the gas furnace with a heat pump qualifies.

Furnace Repair and Installation in Roswell

Basement installed gas furnaces are common in Roswell’s 1960s through 1980s subdivision stock. Many are at or past their 20 year service life. Heat exchanger inspection during seasonal maintenance is non negotiable on equipment that age.

Ductwork Repair, Sealing, and Replacement in Roswell

This is one of the highest impact services for Roswell homes. Original 1970s and 1980s attic ductwork commonly leaks 20 to 30%, and on some pre 1980 installations the ducts are undersized for the current equipment they’re feeding. Duct sealing qualifies for the Georgia Power HEIP home comfort bundle rebate (up to $1,250 when combined with insulation and air sealing).

Indoor Air Quality and Dehumidifiers in Roswell

Roswell’s mature canopy of oak, pine, and sweetgum drives heavy spring pollen exposure and high summer humidity. MERV 13+ filtration, UV C lamps on evaporator coils, and whole home dehumidifiers are routine upgrades in older Roswell homes where original air handlers weren’t designed for modern filtration.

Smart Thermostat Installation in Roswell

Georgia Power’s HEIP gives a $75 instant rebate per smart thermostat replacing a 10+ year old standard model. In older Roswell homes, smart stat installation also surfaces wiring issues common in 1970s and 1980s installations, we handle the C wire or transformer addition when needed.

HVAC Maintenance and Comfort Club in Roswell

For homes with 15+ year old equipment, our Comfort Club seasonal tune ups extend remaining service life by catching degraded components before they become a January no heat call. Priority dispatch, two tune ups per year, discounted repair pricing.

Pricing and offers

Our service call and diagnostic is $89. That covers a certified technician visit, a full system diagnostic, and a written estimate. The fee is waived if you proceed with the recommended repair, and it’s free for Comfort Club members.

No after hours premium. All quotes are written and approved before any work starts.

AC repair: $228 to $3,000+

Capacitor or contactor swap at the low end. Evaporator coil leak repair, refrigerant work on older R 22 systems (which are usually replacement candidates at this point, not repair candidates), and component access on retrofitted historic district installs push toward the upper end.

Furnace repair: $361 to $2,575.

Igniter or thermocouple replacement low end. Heat exchanger inspection is included with maintenance; heat exchanger replacement on a 22 year old basement furnace usually pushes the conversation toward replacement instead. Blower motor and inducer motor assembly work sit middle to upper range.

AC replacement: $2,500 to $8,000+.

Drives the range: tonnage, SEER2 rating, brand, and whether ductwork can be reused. For older Roswell homes where original ductwork is the actual inefficiency source, we measure duct leakage before sizing replacement equipment, sometimes the smarter spend is sealing ducts first, then a right-sized replacement. Financing is available as low as $109/month for a full system.

Furnace replacement: $2,500 to $8,000+.

Efficiency rating and venting reuse drive the difference. On 1980s basement furnaces with original venting, code may require venting updates that add to the install scope.

Complete HVAC system (AC + furnace or full heat pump system): $7,000 to $25,000+.

typically falls in the $1,200 to $2,500 range depending on accessibility and measured leakage. It’s one of the highest-ROI services we sell in Roswell, and qualifies for HEIP rebate stacking.

Comfort Club annual maintenance plan: $177/year.

One AC tune up, one furnace tune up, priority scheduling, 15% off all repairs. For homes with 15+ year old equipment, the tune up component frequently catches degraded components before they become a January no heat call.

Financing:

Available, as low as $109/month for a full system.

Rebate stacking:

Georgia Power HEIP: $75 per smart thermostat, $1,000 heat pump water heater, up to $1,250 home comfort bundle

Neighborhoods we serve in Roswell

  • Historic Roswell and the Canton Street corridor include homes from the late 1800s through the 1940s. HVAC retrofits here often involve creative ductwork routing, electrical service upgrades, and coordination with city historic preservation review for any exterior equipment placement

Martin’s Landing is dominated by 1970s ranch and split level homes. Most are on their second AC system but original ductwork, which is usually where the inefficiency lives, not in the equipment.

  • Brookfield West has similar 1970s and 1980s housing patterns with heavy mature canopy. Spring pollen is a significant factor in seasonal AC maintenance here.

  • Sweet Apple and the Holcomb Bridge corridor mix older subdivision stock with later infill. The work varies by exact build year, but most pre 1990 homes are in retrofit or full replacement territory.

  • Mountain Park (technically its own incorporated city but commonly grouped with Roswell) has older lakefront and wooded lot homes with similar 1960s through 1980s build patterns. Most need the same retrofit and ductwork work as Martin’s Landing and Brookfield West.

FAQs about HVAC in Roswell

My Roswell home was built in 1974. Should I replace the ductwork along with the AC, or just the equipment?

Test the existing ductwork before quoting equipment. A common pattern in Martin’s Landing, Brookfield West, and similar 1970s and 1980s Roswell subdivisions is 20 to 30% duct leakage in attic runs. Putting a new 16 SEER2 system on ductwork that’s leaking a quarter of its airflow into your attic delivers maybe 11 or 12 SEER of actual performance. We measure leakage with a duct blaster, then recommend sealing, partial replacement, or full replacement based on the number, not a guess.

Do I need a special permit to install central AC in a historic district Roswell home?

Yes. Roswell’s historic preservation review covers exterior changes including condenser unit placement, line set routing, and electrical service modifications visible from the street. We’ve worked enough historic district installations to know which placements typically clear review and which trigger redesign requirements [VERIFY: confirm current City of Roswell Historic Preservation Commission HVAC review thresholds].

Is the federal heat pump tax credit still available in 2026?

No. The federal Section 25C tax credit expired December 31, 2025 under the One Big Beautiful Bill Act. Georgia’s GEFA Home Energy Rebates program is now the primary state level incentive, up to $16,000 income dependent through energyrebates.georgia.gov. Georgia Power’s HEIP rebates (up to $1,250 for home comfort bundles, $1,000 for heat pump water heaters, $75 per smart thermostat) stack with GEFA where applicable.

My basement furnace is 22 years old and still runs. Should I replace it before it fails?

For a 22 year old gas furnace, the questions are: has it been on regular maintenance? what does the heat exchanger inspection show? and what’s the cost of a January 2 AM emergency replacement vs a scheduled October replacement? Heat exchanger failures on equipment that age can also present carbon monoxide risks. We do honest assessment, sometimes 22 year old equipment has another 3 years; sometimes it should have been replaced last year.

Why does my AC freeze up during pollen season in April?

Heavy oak, pine, and sweetgum pollen across Roswell’s mature canopy coats evaporator coils and clogs condensate drains. The coil can’t release heat, the system runs longer, and eventually freezes over. Spring tune ups specifically target this: coil cleaning, drain treatment, filter replacement before pollen peaks.

Does Roswell’s water utility (Big Creek + Atlanta Fulton blend) affect HVAC service?

For most HVAC work, no. For heat pump water heater installations and humidifier work, yes, Roswell’s blended water hardness is moderate (~8 gpg), which affects scale buildup in humidifier panels and tankless water heater heat exchangers. We size and recommend with that in mind.

Can I convert my Roswell home from gas furnace + AC to a heat pump?
