Why Brandt HVAC Co Marietta Is Roswell’s Preferred AC Maintenance Company
Our customers in Roswell keep calling us back because we treat older homes the way they deserve to be treated: carefully. From mill village cottages off Atlanta Street to large ranches near Roswell Area Park, every system gets the same methodical inspection, and every job comes with a written price before we touch a single component. Devin Marlowe leads our team with a simple rule: if the homeowner doesn’t understand what we’re doing and why, we haven’t done our job. That’s not a sales pitch. That’s how maintenance should work.
Roswell’s housing stock demands more than a checklist tune-up. We see 19th-century homes retrofitted with central air decades ago, mid-century ranches with original electrical panels, and 2000s subdivisions where flex ducts are starting to sag. Our technicians live in the same climate you do. They know what Georgia humidity does to a coil by August. They know which neighborhoods fight pollen the hardest. That local knowledge means we catch failures before they happen, not after your compressor gives out on a 95°F day.
Dispatch and scheduling are coordinated from our Atlanta office, but the crews serving Roswell are local, familiar with your streets, and ready to answer the phone at 3 a.m. if you need us.

AC Tune Up in Roswell
An AC Tune Up in Roswell means more than changing a filter. It’s a systematic inspection of the components that fail under Georgia’s heat and humidity: capacitor strength, refrigerant pressure, condenser coil cleanliness, blower motor amp draw, and thermostat calibration. Roswell’s humid subtropical climate pushes systems hard for six months a year, and a tune-up should catch the small stuff before it becomes a $650 repair. A standard tune-up here runs $80 – $200, and it takes about an hour. We work on Trane, Lennox, Goodman, and Rheem systems every day.
What the Tune-Up Covers
We test capacitors under load, clean or replace the air filter, check refrigerant levels, inspect electrical connections for arcing or overheating, and clean the condensate drain line. In Roswell, we always check the outdoor coil for pollen and cottonwood buildup, because a clogged coil in June means a system working 30% harder than it should by July.
When Roswell Homeowners Schedule This
Most of our Roswell customers schedule tune-ups in March or April, before the real heat hits. That timing gets the condenser clean before cottonwood season peaks. But a tune-up in September works too, after a long summer of near-continuous runtime. Either way, you get the same written price before work starts, and the same 365-Day Done Right Promise if we miss something.
HVAC Maintenance Service in Roswell
HVAC Maintenance Service in Roswell covers the whole system: the air conditioner, the furnace, the thermostat, the electrical connections, and the ductwork you can access. In a historic home off Sloan Street, that might mean inspecting a Carrier high-velocity mini-duct system for blower pressure and outlet noise. In a 1980s split-level near Crabapple, it might mean checking static pressure on original flex ducts that were sized for a smaller system. A full maintenance visit runs $80 – $200, and you’ll get a written report of what we found, what we fixed, and what might need attention before next season.
System-Wide Inspection and Safety Check
We inspect the electrical panel, the wiring at the disconnect, and the condition of the contactor. Older Roswell homes sometimes have original panels that were never designed for a high-efficiency system’s startup draw. If we find a safety issue, we show it to you in plain language, with a photo, and give you a written price to fix it. Nothing gets done until you agree.
Humidity and Airflow in Roswell’s Older Homes
Roswell’s older construction leaks air. Original pine floors, plaster walls, and window frames move with the seasons, so your system fights humidity and drafts that a newer subdivision home doesn’t. We check airflow at supply registers and return grilles, and we tell you if a duct sealing job or insulation upgrade would make a bigger difference than another refrigerant recharge. Maintenance should save you money, not just keep you cool.
Trusted Brands We Service in Roswell
We service all major residential brands across Roswell: Trane, Lennox, Goodman, and Rheem, plus Carrier, York, Daikin, Bryant, and American Standard. Keeping common parts on hand for these brands means we can often complete a repair during the same visit, not schedule a return trip. In Roswell’s heat, that matters. If your capacitor fails on a Saturday, you don’t want to wait until Tuesday for a part to arrive. Our trucks are stocked for the brands we see most often in Roswell’s neighborhoods, and we know which compressors and coils each subdivision tends to have.
Common AC Maintenance Problems We See in Roswell Homes
- Pollen-clogged condenser coils. Roswell’s high pollen counts in March through May, plus cottonwood in late spring, pack outdoor coils. A clogged coil raises refrigerant pressure, which strains the compressor. We clean coils during every tune-up, not just when the system stops cooling.
- Undersized or leaking original ductwork. Homes built from the 1980s through the 2000s often have flex ducts that were never sized for the load. High static pressure forces the blower motor to work harder, which shortens its life. We measure static pressure during maintenance and tell you if your ducts are the real problem.
- Weak capacitors on older systems. A capacitor provides the starting jolt your compressor and fan motor need. Georgia heat ages them faster than mild climates do. We test them under load on every visit. A capacitor failing in July is a $150 – $650 repair; catching it in April is usually cheaper and far less stressful.
- Electrical panel strain in historic homes. Many Roswell historic district homes still have original panels from mid-century electrical work. A modern high-efficiency AC unit draws differently than the system that was there before. During maintenance, we check connections and breaker sizing, because loose connections at the panel are a fire hazard and a silent failure point.

FAQs About AC Maintenance in Roswell
Historic homes in Roswell often have original pine floors and plaster walls, which makes adding conventional ductwork invasive and expensive. Many use high-velocity mini-duct systems or ductless mini-splits instead. These systems have different pressure thresholds, different filter locations, and different failure modes than standard flex-duct systems. A technician who only knows suburban splits can miss problems a high-velocity system telegraphs early. Our team services these systems regularly in the Roswell Historic District and knows what normal operation looks like for each setup.
In Roswell, we recommend cleaning the condenser coil at least twice a year: once in early spring before pollen peaks, and again in late summer after cottonwood and summer dust have settled. Homes near the Chattahoochee or with heavy tree cover often need a third cleaning. A coil clogged with pollen and cottonwood raises head pressure, which strains the compressor and shortens its life. During a tune-up, we clean the coil as part of the standard service. For high-pollen lots, we can also show you how to rinse it between visits without damaging the fins.
Usually it’s a duct problem, not a maintenance issue. Homes built in Roswell in the 1980s often have flex ducts that were undersized when installed and have since sagged or leaked. The blower motor pushes against high static pressure, so the room farthest from the air handler gets the weakest airflow. During maintenance, we measure static pressure and register temperatures room by room. If the numbers point to duct restriction or leaks, we’ll tell you exactly what we found and give you a written price for duct sealing or targeted repair. Adding refrigerant or cleaning the coil won’t fix a duct problem.
A capacitor failure looks like the outside unit humming but not starting, or the fan spinning slowly, or the system tripping the breaker on startup. It happens fast, often on the hottest day of the year. Yes, it can be caught during routine maintenance. We test capacitors under load on every tune-up visit. A capacitor that tests weak but hasn’t failed yet gives us time to replace it on your schedule, at a planned price, rather than as an emergency on a Sunday afternoon. In the Roswell Historic District off Sloan Street, we caught a weak capacitor during a five-minute test on a 1905 mill village home with a high-velocity Carrier system. That one catch prevented a compressor failure on a 95°F day when the homeowner’s plaster walls would have made a same-day repair nearly impossible.
A standard tune-up does not include a full Manual J load calculation, which is a room-by-room assessment of heating and cooling needs. But we do check airflow, static pressure, and system capacity against the square footage and duct layout we can see. If you’re planning to replace a system, or if your home has obvious comfort problems, we’ll recommend a load calculation as a separate service and explain why a like-for-like swap often disappoints in an older house. An undersized system never catches up in August; an oversized one short-cycles and leaves the house clammy. Roswell’s older homes especially benefit from getting this right before spending thousands on new equipment.
