Commercial HVAC Services in Marietta

Cooling and Heating That Keep Cobb County Businesses Open

When a rooftop unit quits on a 95-degree afternoon, dining rooms empty out, exam rooms become unusable, and tenants start calling the property manager. In Marietta, where the cooling season runs from late April into October, an HVAC failure is an operations problem before it is a comfort problem.

Swift Brothers provides commercial HVAC services in Marietta and across Cobb County for offices, retail centers, restaurants, medical and dental practices, churches, schools, warehouses, and multifamily communities. Our licensed technicians repair, maintain, and replace commercial cooling and heating equipment, and they explain pricing before work begins.

If your building has a cooling or heating problem right now, call (706) 236-7678. Same-day service is often available for commercial customers in Marietta, Kennesaw, Acworth, and East Cobb.

What Marietta’s Climate Does to Commercial Equipment

Cobb County summers combine high heat with humidity that sits in the 60 to 70 percent range for weeks. Rooftop units run long hours removing moisture as well as heat, so condensate drains clog, blower motors work harder, and coils foul faster. Spring adds the pollen: each year a yellow film settles on every outdoor coil in north Georgia, and a coil that goes into summer uncleaned starts the season behind.

Winter is short but not harmless. A few nights in the teens each January are enough to expose heat pumps with weak defrost cycles, gas furnaces with cracked igniters, and rooftop units whose heat sections have not fired since March. Buildings that skipped fall maintenance tend to discover these problems on the coldest morning of the year.

Buildings and Systems We Serve in Marietta

Marietta’s commercial building stock is varied. Strip retail and freestanding restaurants line Cobb Parkway from the Big Chicken north toward Kennesaw, office parks cluster near the I-75 interchanges and the Cumberland and Galleria area, older brick storefronts surround Marietta Square, and light industrial and flex space sits near Dobbins and along the South Cobb corridor. We work in all of them.

Commercial equipment our technicians repair, maintain, and replace:

• Packaged rooftop units, including gas/electric and heat pump configurations
• Commercial split systems and multi-zone ductless systems
• VRF and VRV systems in offices, hotels, and medical buildings
• Make-up air units and kitchen ventilation for restaurants
• Heat pumps, gas furnaces, and unit heaters for warehouses and shops
• Programmable and networked thermostats, zoning, and building controls

Commercial Air Conditioning Repair and Replacement

Cooling is the largest share of the commercial HVAC work we do in Marietta, and it has its own page. If you are dealing with a rooftop unit that will not hold setpoint, uneven temperatures across a tenant space, refrigerant leaks, or a compressor at the end of its life, see our commercial air conditioning services in Marietta for details on diagnostics, repair, and maintenance.

Commercial Heating in Marietta

Heating gets less attention than cooling in Cobb County, which is why it causes so many surprise failures. Most Marietta commercial buildings heat with the gas heat section inside a rooftop unit, a heat pump with electric auxiliary strips, or a standalone gas furnace or unit heater in a warehouse or shop. A few older buildings around the Square run hydronic systems with boilers. We service all of them.

Heating Repair

Common calls include rooftop gas sections that will not ignite, heat pumps stuck in defrost or running on expensive auxiliary heat, blower failures, cracked heat exchangers, and controls that lost their schedule after a power blink. Our technicians find the root cause, check combustion safety on gas equipment, and confirm heat is reaching the space before they leave.

Fall Heating Maintenance

A heating inspection in October or November catches most winter failures while the weather is still mild. We test ignition and flame sensing, inspect heat exchangers, verify gas pressure, check defrost operation on heat pumps, clean burners, and replace filters.

Heating Replacement

When a heat section or furnace is past repair, replacement is usually a matter of matching the existing configuration, confirming gas supply and venting, and coordinating any permits and inspections required by Cobb County or the City of Marietta. Often the more practical option is replacing the entire rooftop unit rather than the heat section alone, and we will walk you through that trade-off.

Maintenance Programs for Multi-Tenant and Multi-Site Properties

A dozen rooftop units across one building or several need more than a phone number to call when something breaks. A commercial maintenance program with Swift Brothers puts every unit on a schedule: spring cooling visits before the humidity arrives, fall heating visits before the first cold snap, filter changes and coil cleaning timed around Marietta’s pollen season, and a written record of each unit’s condition after every visit.

That record makes budgeting possible. When you know which units on the roof are twelve years old and running hot, you can plan replacements over two or three fiscal years instead of absorbing them as emergencies. Programs cover a single Marietta site or a portfolio spread across several counties.

How We Work with Facility and Property Teams

Before arrival, we confirm roof access, key and alarm procedures, and any tenant notification requirements. Repairs that will interrupt cooling to a dining room or a medical suite are scheduled early, late, or on a day the space is closed whenever that is possible. Full rooftop replacements include crane lifts, utility shutoffs, and inspections coordinated with your team. Every visit ends with a plain-language summary of what was found, what was done, and what should be watched.

Commonly Asked Questions

Do you service commercial HVAC systems outside Marietta?

Yes. Our Marietta team covers Cobb County and north Georgia, including Kennesaw, Acworth, Smyrna, Woodstock, Canton, Cartersville, and Ellijay.

Can you work on rooftop units from any manufacturer?

Yes. We service rooftop and packaged equipment from all major commercial manufacturers and source parts for the units most common in Cobb County buildings.

How often should commercial HVAC equipment in Marietta be maintained?

At least twice a year, once before cooling season and once before heating season. Restaurants, medical facilities, and buildings with heavy pollen exposure often benefit from quarterly filter and coil service.

Do you handle the permits for a rooftop unit replacement?

Yes. We coordinate the mechanical permit and inspection with the City of Marietta or Cobb County and tell you up front if the existing installation will need to be brought up to current code.

Can heating and cooling service be done on the same visit?

In most cases, yes, since packaged rooftop units contain both. Seasonal visits are still the better way to catch problems before each season starts.

What if my tenant reports the problem instead of me?

We can take requests directly from tenants when the property manager sets that up in advance. Findings and approvals go back to whoever is responsible for the equipment under the lease.

Do you repair make-up air and kitchen exhaust systems for restaurants?

Yes. Make-up air units, exhaust fans, and the controls that balance them are a frequent source of comfort and pressure problems in Marietta restaurants, and we service all of them.
