AC maintenance in Marietta runs $80 – $200 for a full tune-up, and that single visit prevents most of the $150 – $650 repairs we see every summer. The pollen, the humidity, and the age of Marietta’s housing stock all work against your system, and a neglected unit fails at the worst possible moment. Our AC Maintenance team knows exactly what these homes need, and every technician arrives background-checked, badged, and introduced by name and photo before they knock. Call (478) 662-5175 and a live person answers, 24/7.
Why Brandt HVAC Co Marietta Is Marietta’s Preferred AC Maintenance Company
Homeowners in Marietta don’t want a stranger at the door. They want someone named, verified, and accountable before the visit even starts. That’s the Threshold Verified standard we built this business on. Every technician is background-checked and identity-verified. We send you their name and photo ahead of time, and they show a photo ID badge when they arrive. If someone shows up who you were not told to expect, that visit is on us. We make it right.
Devin Marlowe leads our Marietta crews, and the work he expects reflects what homeowners here tell us they want: a written price before any work starts, a written guarantee on every repair, and a real person answering the phone at 2 a.m. when the AC dies during a July heat wave. No voicemail trees. No callback queues. You call, a human picks up.
We service every major residential brand, including Trane, Lennox, Goodman, and Rheem, and we stock the common wear parts for Marietta’s older systems. When a 1982 split-level in the Whitlock Avenue corridor needs a capacitor, we’re not waiting three days on a parts truck from across town.
Styles & brands we work with







HVAC Maintenance Service in Marietta
HVAC Maintenance Service in Marietta means dealing with two things most homeowners never see: pollen-blasted condenser coils and ductwork that’s been choking airflow since the Carter administration. A proper maintenance visit covers the condenser coil wash, the capacitor test, the drain line flush, and a check of static pressure across the blower. In Marietta’s housing stock, skipping any one of those items shortens equipment life by years. A full maintenance visit typically runs $80 – $200.
Coil Washing and Pollen Removal
Marietta’s oaks and pines release a thick pollen load every spring, and it doesn’t just coat your car. It packs into the condenser coil fins and raises head pressure until the compressor trips its high-limit switch. We wash the coil, check the refrigerant charge, and verify the system isn’t running hot before the first 95°F day hits.
Static Pressure and Blower Testing
Decades-old flex duct in crawl spaces collapses, kinks, and fills with dust. The blower motor works harder to push air through it, amp draw climbs, and the motor burns out. We measure static pressure on every maintenance visit in Marietta because the ductwork here makes this the number one hidden killer of blower motors and capacitors.
HVAC Tune Up in Marietta
An HVAC tune up in Marietta should tell you what’s about to fail before it fails on the hottest afternoon of the year. We test the capacitor, check the contactor, measure the temperature split across the coil, and inspect the condensate drain for the algae buildup that’s constant in this humidity. A tune-up here runs $80 – $200, and the written report you get afterward tells you exactly what we found, what it means, and what it costs to fix if anything needs attention.
Capacitor Testing on Aging R-22 Systems
Most of the 1980s ranch homes around Roswell Road and Sandy Plains still run R-22 systems that are 15 to 25 years old. A weak capacitor on one of those units doesn’t just cause a no-cool call. It often takes the compressor down with it when the system tries to start against high head pressure. We test every capacitor on every tune-up, and we replace weak ones before they cost you a $4,000 compressor.
Drain Line and Airflow Check
Marietta’s humidity means condensate drains clog constantly. A backed-up drain trips the float switch and shuts the system down, or worse, overflows into the air handler and soaks the crawl space. We flush the line, clear the trap, and check the airflow across the evaporator so the system isn’t freezing up during a long August run.
Trusted Brands We Service in Marietta
We work on Trane, Lennox, Goodman, and Rheem systems every week in Marietta, and we’re familiar with the failure patterns specific to each. Rheem and Goodman units from the late 1990s have capacitors that degrade predictably in this heat. Lennox systems with variable-speed blowers need specific static pressure verification. Trane’s coil design handles pollen better than most, but the drain pans still clog in this humidity. We keep the common parts for all four brands on our trucks, which means faster service when you need a repair, not just a diagnosis.
Common AC Maintenance Problems We See in Marietta Homes
- Condenser coils packed with oak and pine pollen. Late spring in Marietta coats every outdoor unit in a sticky yellow film. That film insulates the coil, drives up head pressure, and trips the high-limit switch by midsummer unless the coil gets washed before the heat arrives.
- Weak capacitors on aging R-22 systems in 1980s ranches. A capacitor loses capacity slowly, then fails suddenly. On a hot day, a weak capacitor forces the compressor to work harder at startup, and that extra strain can destroy the compressor winding. Testing takes minutes. Replacing it costs far less than a compressor.
- High static pressure from original ductwork in 1960s and 1970s split-levels. Undersized returns and decades of collapsed flex duct in crawl spaces make the blower motor draw more amps than it’s rated for. The motor overheats, the bearings wear, and the capacitor works harder. Static pressure testing shows the problem before the motor fails.
- Clogged condensate drains from constant summer humidity. Marietta’s humid subtropical climate means your AC pulls gallons of water out of the air every day. Algae grows in the drain line, the trap clogs, and the float switch shuts the system down at the worst possible time. A drain flush on every tune-up prevents most of these calls.

FAQs About AC Maintenance in Marietta
Every spring, before the heat arrives. Marietta’s oak and pine pollen season runs from late March through May, and that pollen packs into condenser coil fins and stays there all summer. One coil wash a year, done after the pollen peak, keeps head pressure down and prevents most compressor trips. If your unit is near a treeline or under oaks, twice a year is safer. Call (478) 662-5175 and we’ll schedule the wash before the first 90°F stretch.
Because the ductwork in most 1970s split-levels is undersized for the airflow a heat pump needs in heating mode, and the system can’t move enough warm air through the house when outdoor temperatures drop fast. We call it the “Marietta split.” The heat pump itself is often fine; the ductwork is the bottleneck. A static pressure test shows the restriction, and sometimes a return-air improvement solves it without replacing the equipment. We pulled up to a 1970s split-level on Booth Road where the heat pump’s condenser coil was so choked with late-spring oak pollen that the head pressure had tripped the high-limit. After a full wash and a capacitor test, our tech found the blower motor drawing 40% over rated amps from fighting the home’s original undersized ductwork, and we scheduled a static pressure test before the next cold snap. Call (478) 662-5175 and we’ll do the same diagnosis on your system.
Yes. A capacitor test takes about five minutes with a multimeter, and it works on any brand, including Lennox and Rheem. We read the microfarad rating against the label on the capacitor itself. If it’s more than 10% below rated, it’s weakening, and on a hot day in Marietta, that weak capacitor will fail or take the compressor with it. Most tune-ups include this test. If you don’t know the last time yours was checked, call (478) 662-5175 and we’ll check it before the next heat wave.
No, you don’t need to replace a working R-22 system just to meet current SEER2 standards. New installations in Georgia are required to meet SEER2 minimums, but an existing system can run as long as you’re willing to maintain it and pay for R-22 refrigerant, which is expensive and getting scarcer. For a 1980s crawl-space home, the bigger question is whether the ductwork and airflow can support an efficient new system anyway. We’ll tell you straight if your money is better spent on duct sealing than on a new condenser. Call (478) 662-5175 and we’ll walk you through the numbers for your specific home.
A full tune-up on a Goodman or York system with aging ductwork includes a condenser coil wash, capacitor test, contactor inspection, drain line flush, refrigerant charge check, temperature split measurement, and a static pressure reading across the blower. The static pressure reading is the most important item for older Marietta homes because it tells you whether the ductwork is strangling the system. You get a written report with all readings and a fixed price for anything we recommend. Call (478) 662-5175 for a free estimate.
