Best HVAC Companies in Marietta, GA (2026)
We may earn a commission if you sign up through links on this page. It doesn't change what you pay or our recommendations.
Marietta has one of the most competitive HVAC markets in North Atlanta — 43 contractors serve the area with an average 4.5-star rating across more than 8,000 reviews. That competition is good news for homeowners: pricing stays honest and service quality is high.
One Marietta-specific note before we get into contractors: if you're in East Cobb with a Marietta address but outside city limits, your electric provider is Cobb EMC rather than Georgia Power, and Marietta Power serves the city itself. That doesn't change who you call for HVAC, but it affects available rebate programs — worth knowing before purchasing new equipment.
With 47 days above 90°F annually and cold winter snaps, Marietta's HVAC systems earn their keep year-round. This guide covers the top-rated contractors, what to expect to pay, and how to choose the right one.
What HVAC Work Costs in Marietta
| Service | Typical Cost Range |
|---|---|
| AC repair | $150–$550 |
| Heating repair | $150–$500 |
| Annual maintenance tune-up | $70–$200 |
| Full HVAC inspection (both systems) | $150–$400 |
| Ductless mini-split (single zone) | $2,000–$8,000 |
| Central AC replacement (existing ductwork) | $3,500–$12,000 |
| Full system installation with new ductwork | $7,000–$20,000 |
For a 2,000-square-foot Marietta home, look for an AC unit between 2.5 and 5 tons — on the higher end given Georgia's heat — and a furnace between 50,000 and 80,000 BTUs. Marietta's relatively mild winters mean you may be able to size toward the lower end of the furnace range.

PV Heating & Air — Best for Reviews and Warranty
PV Heating & Air serves Marietta from Johnson Ferry Road in East Cobb to the historic downtown square.

Dayco Systems — Best for After-Hours Response
Dayco earns specific Marietta praise for after-hours responsiveness — one HomeAdvisor reviewer came home worried about going days without cooling, called Dayco on a recommendation, and had the unit fixed that same evening.

Bartlett Heating & Cooling — Best for Maintenance Plans
Bartlett stands out in Marietta's maintenance market for technician specificity — Evan, Mitchell, Willie, Bo, Stephen, and Josh each appear by name in customer reviews, with consistent notes on thoroughness and genuine care. For biannual tune-ups, which Marietta's dual-season climate genuinely requires, a company with consistent named technicians is preferable to one that rotates staff randomly.

Coolray Heating & Air Conditioning — Best for Lifetime Warranty
Coolray's Lifetime Parts and Labor Warranty — available to maintenance plan members who pay $0 for repairs — is one of the strongest warranty offerings in the Marietta market. Technicians Jeremy and Wes handle both maintenance visits and follow-up repairs, creating continuity for plan members.

Best for: Costco members who want access to vetted contractor pricing, or homeowners interested in air purification alongside HVAC
CoolPro Heating and Cooling — Best for Speed
CoolPro earns specific Marietta Yelp praise for response speed — one reviewer's AC went out on a Saturday night, CoolPro called back Sunday morning at 8:30, and by 8:20 AM the technician had arrived and finished. That kind of response time is the exception, not the rule, in the HVAC market.
Best for: Homeowners who prioritize fast response times above everything else
How to Choose an HVAC Contractor in Marietta
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 work begins.
Know your electric provider before buying new equipment. Marietta Power, Cobb EMC, and Georgia Power all serve different parts of the Marietta area and each has different rebate programs for energy-efficient equipment. Confirm your provider first.
Get at least two quotes on installations. With 43 contractors serving the market, competition keeps pricing honest — but quotes can still vary by thousands of dollars for identical work.
Ask about maintenance plans. Marietta's dual-season climate means your HVAC runs both heating and cooling seriously. Biannual tune-ups prevent the expensive emergency calls that peak summer demand makes worse.
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 makes more financial sense.
Signs it's time to replace:
- Frequent breakdowns in the past two years
- Rising utility bills without explanation
- Uneven temperatures between rooms or floors
- R-22 (Freon) refrigerant — federally phased out, increasingly expensive
- 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.
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. Older articles promising a federal credit are out of date.
What's available now:
- Georgia Power Home Efficiency Improvement Program (HEIP): If Georgia Power is your electric provider, the 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.
- Electric membership cooperative (EMC) rebates: If your home is served by an EMC such as Cobb EMC or Sawnee EMC instead of Georgia Power, check with them directly. Georgia EMCs set their own heat pump rebates, often in the range of $100 to $600.
- 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 your electric provider and your contractor before you buy equipment.
