Best HVAC Companies in Alpharetta, GA (2026): Repair, Replacement, Heat Pumps & Warranties

Looking for an HVAC contractor in Alpharetta? Here is the short version: North Point Heating and Air, PV Heating & Air, and Dayco Systems are the strongest picks for most homeowners, with Kennon, The Air Company of Georgia, Cool Air Mechanical, and A&K Service as solid alternatives. Below you'll find what each is best at, what common jobs cost in 2026, and what to ask about warranties before you sign for a heat pump or furnace replacement.

Alpharetta's newer developments, including Windward, Avalon, and Crabapple, have some of North Atlanta's most efficient housing stock. But Georgia's climate still makes your system work hard: roughly 50 days above 90°F a year, heat index readings over 100°F, and cold snaps in January and February. Heating and cooling account for about 55% of the energy used in a typical Alpharetta home, so the contractor you pick directly affects your utility bills.

What HVAC Work Costs in Alpharetta (2026 Estimates)

Prices vary with home size, equipment brand, and ductwork condition. These ranges track Atlanta-metro averages.

For a 2,000-square-foot Alpharetta home, expect an AC between 2.5 and 5 tons, toward the higher end given Georgia's heat load. A furnace between 50,000 and 80,000 BTUs is typical, and Alpharetta's relatively mild winters mean you can often size toward the lower end.

Heat Pump or Furnace Replacement in Alpharetta: What to Know

Most Alpharetta homes have either a gas furnace with a central AC or a heat pump that handles both heating and cooling. Which one makes sense depends on what you have now and what you're willing to spend.

Heat pump: One system provides cooling and heating, and it is efficient in Alpharetta's mild winters. It runs on electricity (Georgia Power serves Alpharetta), so your heating cost depends on electric rates rather than gas prices. If you're replacing an old electric furnace or electric heat strips, a heat pump is usually the biggest efficiency upgrade available.

Gas furnace + AC: Often a lower upfront cost, and many homeowners prefer the heat output on the coldest January nights. If you already have gas piped to the home, replacing like-for-like is the simplest path.

Dual fuel: A heat pump paired with a gas furnace backup. It costs more upfront but gives you both efficiency in mild weather and gas heat on the coldest days.

Ask every contractor to quote at least two options (for example, a like-for-like replacement and a heat pump) so you can compare total installed cost, not just equipment price.

Understanding HVAC Warranties Before You Sign

When you compare replacement quotes, the warranty is often the difference between two similar prices. There are two separate warranties, and contractors don't always explain both.

1. Manufacturer equipment warranty. This covers parts. Many major brands offer a 10-year parts warranty, but often only if you register the equipment within a set window after installation (commonly 60–90 days). Skip registration and you may get a much shorter default term. Ask the contractor whether they register the equipment for you.

2. Contractor labor warranty. This covers the cost of the technician's time if a covered part fails. Labor warranties are often short, commonly 1–2 years, and are the part most homeowners overlook. Some contractors offer extended labor coverage of 5–10 years, sometimes included and sometimes as a paid add-on.

What to ask before signing:

• How long is the parts warranty, and do you register it for me?
• How long is your labor warranty, and what does it exclude?
• What is covered on the compressor and heat exchanger specifically? These are the most expensive components.
• Is the warranty transferable if I sell the house?
• Do I need to keep a maintenance plan active to keep the warranty valid?

Get all of this in writing on the quote, along with the brand, model number, and efficiency rating.

Georgia Power Rebates and Incentives for HVAC Upgrades in 2026

Federal tax credits are no longer available. The 25C credit that previously offered up to $2,000 for heat pumps expired for equipment installed after December 31, 2025. If you've seen older articles (including older versions of ours) promising a federal credit, that information is out of date.

What's available now:

• Georgia Power Home Efficiency Improvement Program (HEIP): Georgia Power's current program cycle, effective August 1, 2026, covers up to 50% of installed cost per measure, with a program-wide limit of around $2,500 per customer per year. Listed maximums include up to $500 for a ductless mini-split and up to $800 for a heat pump water heater. The larger heat pump rebate (up to $1,500) applies only when replacing electric heating equipment, so homes with gas furnaces generally don't qualify for it, though they may qualify for weatherization bundles. Equipment typically must be ENERGY STAR certified.
• Georgia Home Efficiency Rebates (HER): A state program open to all income levels and not limited to electric homes, but it requires a GEFA-approved contractor and a project that achieves a minimum level of energy savings. The state's other rebate program (HEAR) has paused new applications.

Program terms change, and some require pre-approval or an approved contractor. Confirm current eligibility with Georgia Power and your contractor before you buy equipment.

How to Choose an HVAC Contractor in Alpharetta

Verify Georgia licensing. HVAC contractors must hold a Class I or Class II license from the Georgia State Board of Conditioned Air Contractors. Ask for the license number before any work begins.

NATE certification is a quality signal. North American Technician Excellence certification means a technician has passed an independent third-party exam. North Point carries NATE-certified staff.

Get written quotes on installations. For any replacement, get at least two written quotes specifying equipment brand, model, efficiency rating, and warranty terms, not just a total price.

Ask about equipment sizing. Alpharetta's heat load means sizing toward the higher end of the recommended range for your square footage. An undersized system runs constantly and wears out faster; an oversized system short-cycles and creates humidity problems.

Check for financing. Dayco offers 0% for 60 months on qualifying systems; A&K works with 13 lenders through Hearth. For a $10,000 replacement, financing terms matter.

When to Repair vs. Replace

General rule: if your system is more than 10–12 years old and repair costs exceed 50% of a new system's price, replacement is usually the better financial decision.

Signs it's time to replace:

• Frequent breakdowns in the last two years
• Rising utility bills without explanation
• Uneven temperatures between floors, which is common in Alpharetta's two- and three-story homes
• R-22 (Freon) refrigerant, which is federally phased out and increasingly expensive to recharge
• An older, low-efficiency system. Current federal minimums for new systems in Georgia are roughly 14 SEER2 or higher, so a unit from the early 2000s is likely far less efficient
