HVAC Repair and Replacement in Smyrna, GA
Smyrna is a Cobb County city just northwest of Atlanta and south of Marietta. Summers here are long and humid, which is hard on an air conditioner or heat pump, and winters are usually mild but still cold enough that the heat has to keep up on clear mornings. If the house cools but still feels clammy, the cause is often airflow, a dirty coil or an incorrect refrigerant charge rather than a unit that is simply “too small.”
Before we talk about new equipment, we look at how the current system is running. Sometimes a repair is the right answer. When replacement makes more sense, we price the options side by side after a free in-home estimate.

Recent Work in Smyrna
Two full system replacements in Smyrna, Goodman equipment.
In November 2026 we replaced two complete heating and cooling systems with Goodman equipment for a Smyrna homeowner. The photo with our yard sign is from that job. Each system got the same checks as every system we install. See the Comfort Medics Installation Standard.
Replacing a System in Smyrna
At the free in-home estimate we look at your current equipment, ductwork, refrigerant lines, gas line and venting, and we size the new system with a load calculation for your home. You get an upfront price before any work is scheduled. Removal and disposal of your old equipment is included.
If you’re comparing options, see furnace replacement, heat pump installation or HVAC replacement and installation. For price ranges, see our HVAC replacement cost guide.
Our Smyrna installs follow the Comfort Medics Installation Standard, performed as applicable to the equipment and project: refrigerant charge and airflow on an AC or heat pump, temperature rise, gas pressure, and flue sizing on a gas furnace, plus electrical and condensate checks before we leave.
Starting prices, as of November 2026: air conditioner replacement starts at $5,000, furnace replacement at $4,000, evaporator coil replacement at $2,000, a heat pump outdoor unit (air handler not included) at $2,000, and a complete system at $7,000. Your final price depends on your home’s size, ductwork, equipment efficiency and the options you choose, and we quote it after a free in-home estimate. Already have a replacement quote? A second opinion before you decide is free.
Permits: City of Smyrna or Cobb County
We pull a permit on every replacement. Inside Smyrna city limits, the City of Smyrna Building Division requires a permit for replacement of mechanical equipment, and applications go through the city’s online permitting portal (in-person submittals are no longer accepted). A Smyrna mailing address is not always inside the city, so we confirm which jurisdiction applies to your address first. Outside the city in unincorporated Cobb County, Cobb County Community Development’s Building Division handles permitting and inspections. You don’t need to sort out which office applies; we take care of the permit either way.
Warranty and Financing
A new system from Comfort Medics comes with a 10-year manufacturer parts warranty on qualifying equipment (registration may be required), a 10-year labor warranty from Comfort Medics and our lifetime craftsmanship guarantee. Optional third-party extended coverage, such as JB Warranties, is also available. If monthly payments work better, financing is available through FTL Finance and other lenders, for repairs and new systems (subject to credit approval); see our financing page.

Smyrna HVAC Questions
Do you really come to Smyrna from Kingston?
Yes. Smyrna is one of the towns we serve, and we’ve replaced systems there.
Is the estimate free?
Yes. In-home estimates for a new system are free.
How long does a typical changeout take?
Most changeouts take about 2–3 hours. Ductwork or electrical changes, when they’re needed, can add time.
Do I have to do anything about the permit?
No. We pull the permit on every replacement and confirm the right office for your address first, since a Smyrna mailing address is not always inside the city.
Can you come out at night or on a weekend?
Yes. We offer 24/7 emergency service. Call (470) 360-8887.
