Top HVAC services in Suwanee

Most calls we run in Suwanee are on systems installed when the subdivision was built. Capacitor failures, refrigerant leaks from the evaporator coil, and condenser fan motor failures are the three most common diagnoses on 15 to 20 year old equipment in this climate.

AC Installation and Replacement in Suwanee

When a repair quote crosses 50% of replacement cost on a system over 12 years old, we tell you straight. The honest math on a 2003 build's original AC is usually: replace it. We size with a Manual J load calculation and we'll quote single stage, two stage, and variable speed side by side so you can see the tradeoff.

Heat Pump Installation in Suwanee

A lot of newer Suwanee homes already run on heat pumps as their original equipment, so the conversation here is usually heat pump replacement, not conversion from a gas furnace. If you're upgrading from a 1990s split AC plus furnace combo, dual fuel is worth a look.

Furnace Repair and Replacement in Suwanee

Most Suwanee furnaces are 80% AFUE or 90%+ condensing units in attic or closet installations. Heat exchanger cracks and ignitor failures are the most common repair calls.

Ductwork and Duct Sealing in Suwanee

The two story master planned floor plans common in Settles Bridge and Suwanee Creek subdivisions almost always have attic ductwork in unconditioned space. After 20 years, those duct runs commonly leak 20% to 30%. Aeroseal and traditional duct sealing both qualify for Georgia Power's Home Energy Improvement Program rebate up to $1,250 when bundled with insulation and air sealing.

Indoor Air Quality in Suwanee

Heavy spring pollen (oak, pine, cedar from February through May) loads up filters and condensate drains fast on homes with mature trees. MERV 13 filter upgrades, UV C lamps, and whole home dehumidifiers handle the humidity load that 70%+ summer relative humidity puts on AC systems.

Smart Thermostats in Suwanee

Georgia Power's HEIP gives you a $75 instant rebate per smart thermostat replacing a 10+ year old standard model. Most Suwanee subdivisions have HOA covenants that don't restrict thermostat brand, so the decision is about features and the ecosystem you want to live in.

Our Comfort Club covers an annual AC tune up and an annual furnace tune up, plus priority scheduling and 15% off all repairs, for $177 a year. It pays for itself the first time it catches a low refrigerant charge before the coil freezes.

AC repair:

$228 to $3,000+. A capacitor swap sits near the low end. A compressor replacement, evaporator coil replacement, or refrigerant leak repair on an R 410A system sits near the high end.

A note on what can push your specific quote within these ranges in Suwanee: HOA approval timelines for outdoor unit relocations in master planned subdivisions (Settles Bridge, the Town Center area, Suwanee Creek vicinity) can add days to scheduling but don't change equipment pricing. Gwinnett County permit fees are similar to Forsyth but different from Fulton, and they're included in our written estimate.

Neighborhoods we serve in Suwanee

We dispatch across the city's 30024 ZIP and into the broader Suwanee service area.

  • Settles Bridge. Heavy master planned subdivision activity from the late 1990s and early 2000s. Most homes here are on their first replacement cycle for the original split AC. Two story floor plans almost universally have attic ductwork that's leaking by year 20.

Suwanee Town Center area. Newer construction from 2010 onward, mixed use development, generally newer equipment but the high humidity load from being lower in the watershed makes variable speed compressors a real value add, not just an upsell.

  • Suwanee Creek Greenway corridor. Older established homes alongside newer infill. Mature tree canopy means heavier pollen exposure on filters and condensate drains every spring.

  • McGinnis Ferry Road corridor. Straddles the Suwanee/Johns Creek line. Mix of late 1990s subdivisions and newer construction. Permits here go through Gwinnett County for the Suwanee side and Fulton County for the Johns Creek side, which matters if your house sits near the boundary.

FAQs about HVAC in Suwanee

Do I need a permit to replace an HVAC system in Suwanee?

Yes. HVAC equipment replacement in Suwanee requires a permit through Gwinnett County Department of Planning & Development, plus city level review for some work in the Suwanee city limits. We pull the permit as part of the install and the fee is in your written estimate. Permits for like for like equipment swaps are typically issued within a few business days.

Does Suwanee have soft or hard water, and does it affect my HVAC?

Suwanee is served by Gwinnett DWR pulling from Lake Lanier, and the hardness comes in at 1.3 gpg, which is soft. Soft water doesn't damage AC equipment directly, but it does mean homeowners here don't need to worry about scale buildup on humidifier evaporator pads or whole house humidifier solenoid valves the way Fulton County homeowners on the Chattahoochee source do.

My upstairs bedrooms are 8°F warmer than downstairs. Is my AC bad or is it something else?

On a two story Suwanee master planned home, that almost never means the AC is bad. The two most common causes are undersized return air ductwork on the second floor and 20% to 30% leakage in attic supply ducts. We diagnose both with airflow measurements and a duct pressure test. The fix is usually a return air addition and Aeroseal duct sealing, not a new system.

Is the federal $2,000 heat pump tax credit still available?

No. The federal Section 25C tax credit for air source heat pumps expired on December 31, 2025 under the One Big Beautiful Bill Act. As of 2026, there's no federal tax credit for air source heat pump installation. Geothermal heat pumps still qualify for 30% under Section 25D through 2032. Georgia's state rebate program (GEFA) is now the primary incentive path, with up to $16,000 available depending on household income and projected energy savings.

My subdivision has an HOA. Do you handle approval for outdoor unit replacement?

Yes. Most Suwanee HOAs in Settles Bridge and the Town Center area require approval for any equipment that's visible from the street or changes the screening around an outdoor unit. We provide the equipment spec sheet, dimensions, and a placement diagram for your HOA architectural review. Approval timelines vary by board meeting schedule, which is the only reason an HVAC replacement might take longer than the install itself. [VERIFY: specific HOA names and approval requirements per subdivision]

How long does a full AC replacement take?

For a standard single system Suwanee home, a like for like AC replacement is a one day install. A complete HVAC system replacement (AC and furnace, or a full heat pump conversion from a gas furnace) is typically one to two days. Multi zone equipment for larger 4,000+ sqft homes can run two to three days.

Do you service Comfort Club tune ups on weekends?

Yes. Comfort Club members get priority scheduling, which includes weekend tune up appointments when our weekday slots are booked out. There's no weekend premium for members.
