Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
HVAC trouble shows up in many ways. If you're facing any of these problems, contact our team right away for fast, professional help.
Warm air from the vents usually traces to a weak capacitor, a refrigerant leak, or a frozen coil, all fixable, and all diagnosable in one visit.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementIf some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.
Air duct cleaningMini-splits deliver precise heating and cooling to a single zone, run whisper-quiet, and sip electricity compared to window units.
Mini-split installationA house at 90 degrees is an every-hour problem, so we treat it like one. Same-day appointments across Marietta, with evenings and weekends available.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
Plenty of companies sell a new system the moment yours hiccups. We diagnose first, explain what actually failed, and only recommend replacement when the math genuinely favors it.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
Marietta HVAC has been keeping homes comfortable in this community and the surrounding GA towns for more than 15 years. We understand the local climate and the wear it causes because we live and work here too.
Knowing Marietta is half the job. We've learned which neighborhoods run undersized ducts, how the local climate loads systems season to season, and what inspectors here look for on permits, and we put that knowledge to work on every job so it's done right the first time.
Call a local HVAC expert. Upfront pricing, no obligation.
Every job runs through the same proven steps, so nothing gets missed and the fix actually lasts.
Pick up the phone and dial (770) 202-3453. A few quick questions later, your appointment is on the calendar, frequently the same day.
We don't guess. The diagnostic covers the full system and turns into a straightforward recommendation with the cost spelled out up front.
We complete the approved work on the spot whenever possible: quality parts, code-compliant connections, and no shortcuts hidden behind the air handler.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
Our team answers your call promptly, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and gets you on the schedule, often same-day. We'll guide you on the quick checks worth trying first in the meantime.
Right away, our fully equipped technician is at your door with the parts and tools required to diagnose and begin the repair in your property.
The fault is pinpointed, capacitor, motor, refrigerant leak, control board, or the compressor itself. Then, we complete the repair on the spot whenever parts allow, or quote the replacement with real numbers if the unit is done.
Lasting comfort is the whole point. We verify the repair, note the system's age and condition, and offer a simple seasonal plan that keeps efficiency up, breakdowns down, and miserable nights off your calendar.
"Another company quoted us a full system replacement. Marietta HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. You remember honesty like that."
"From the estimate to the final walkthrough, the whole install was smooth and organized. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote exactly. The new system is so quiet we barely notice it running. Highly recommend."
"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."
Good HVAC service comes down to doing the small things right. These are the commitments that earn Marietta HVAC repeat customers and referrals year after year.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
We match every replacement to an actual load calculation rather than defaulting to whatever's on the truck. Installations include the details that matter: correct gas and electrical work, balanced airflow, and full commissioning. Most installs are completed in a single day with minimal disruption.
We don't wait for failures to profit from them. Every maintenance visit is built around your system's age and condition. For hard-working systems, a spring coil cleaning is the difference between year 10 and year 15. Period.
Wherever you are in our service area, we've got it covered, with fast repairs, quality installs, and maintenance plans reaching every community on our list.
