AfterFast, Reliable AC Installation Across Marietta
Central AC installation in Marietta usually runs $3,500-$7,500 for a complete system, depending on home size, duct condition, and equipment efficiency. Most families in Marietta can get a new system installed within a week of the estimate, and the actual install takes one to two days. If you’re looking at a failed compressor, a leaking coil, or a 20-year-old system that can’t keep up with a Georgia July, call (747) 966-3037 for a free, no-pressure estimate.
We know Marietta’s homes because we work on them every week. From 1950s Lockheed-era ranches west of the Square to 1990s East Cobb subdivisions with multi-zone air handlers, the houses here demand a level of care that a stock single-family changeout often misses. We measure, calculate, and commission every system so it actually does what the equipment label promises. Luis Serrano leads our Marietta install crews, and he holds the team to one standard: the home should be cleaner when we leave than when we arrived.
Why Meadowsweet Heating & Air Is Marietta’s Preferred AC Installation Company
Marietta homeowners call us for a few reasons that have little to do with flashy advertising. We answer the phone with a live person, 24 hours a day. When a condenser dies on a July Saturday, you don’t want a voicemail queue. You want someone who can dispatch a tech to your zip code the same day, and that’s what we do.
We also write down the price before any work starts. Luis Serrano and his crews operate under the Cedarwell Care Promise, which means every job includes a written price, shoe covers and drop cloths inside the home, and a photo of the clean-up before the crew pulls out of the driveway. That’s not an add-on. It’s the minimum for every installation we do in Marietta.
The 365-Day Done Right Promise covers the work for a full year. If something isn’t done right, we come back and fix it. No runarounds, no fine print. That’s the same promise backing every AC Installation we perform, whether it’s a modest ranch in west Marietta or a five-ton multi-zone system off Murdock Road.
HVAC Installation in Marietta
HVAC Installation in Marietta involves far more than setting a condenser on a pad and connecting two copper lines. In this city, the job frequently means evaluating a 60-year-old duct system in a crawlspace, or a 25-year-old flex-duct run through an un-vented attic, or a zone control board that was never balanced correctly in the first place. A proper installation starts with a room-by-room load calculation and ends with static pressure verification, refrigerant charge confirmation, and thermostat calibration. Skip those steps and you get a brand-new system operating at 80% of its rated efficiency while the humidity stays awful.
A complete central air installation in Marietta generally runs $3,500-$7,500. The spread reflects equipment efficiency and home size. A 1,400-square-foot west Marietta ranch will land on the lower end; a 4,000-square-foot East Cobb two-story with dual zones will land higher. What you pay for is not just a box. It’s the engineering that makes the box work in your specific house.
Multi-Zone and Multi-System Design
Larger Marietta homes built between 1985 and 2005 often have two or more air handlers serving separate zones. Replacing one without measuring the other’s airflow and return sizing is a recipe for endless comfort complaints. We calculate each zone’s load separately, then match equipment so the upstairs and downstairs finally behave like they belong to the same house.
Duct Evaluation and Retrofit
New high-efficiency equipment cannot overcome leaking, collapsed, or undersized ducts. In Marietta, where aging ductwork is the rule rather than the exception, we inspect trunks, returns, and plenums before we quote equipment. If the ducts need replacement, we tell you upfront and include it in the written price. No surprises after the unit is already in the driveway.
Heat Pump Installation in Marietta
Heat Pump Installation in Marietta has become more common over the last five years, especially in homes without natural gas service or in households tired of paying Cobb EMC and Georgia Power rates for auxiliary strip heat. For those needing Furnace Repair in Marietta, we also service existing gas systems that pair with these setups. A properly sized heat pump can heat a Marietta home efficiently for all but the coldest stretches, and a dual-fuel setup pairs a heat pump with a gas furnace for the sub-20°F nights that occasionally hit the Blue Ridge foothills.
Heat pump installation in Marietta typically runs within the same $3,500-$7,500 range as central AC, with variable-speed and cold-climate models pushing toward the upper end. The real difference is the care needed during commissioning. A heat pump’s refrigerant charge in both heating and cooling modes must be verified. If a tech skips this step, the system’s rated efficiency never shows up on your bill.
Cold-Snap Performance
Marietta’s climate throws a curveball at heat pumps roughly every other winter. When temperatures drop below 20°F, many standard heat pumps can’t extract enough heat from outside air and switch to electric strip heat, which is expensive. We size the strip heat and the thermostat staging so the transition is seamless and the electric bill doesn’t spike unexpectedly.
Humidity Control in Summer
Marietta’s dewpoints sit in the low-to-mid 70s from June through September. A heat pump that removes latent heat well is more comfortable than an oversized unit that blasts cold air for ten minutes and shuts off. We size for dehumidification, not just temperature drop, which means the house feels dry at 75°F instead of sticky at 72°F.
Trusted Brands We Service in Marietta
Our Marietta installers are factory-trained on Trane, Lennox, and Goodman equipment, which covers most of what we see in homes across the city. For heat pumps and higher-efficiency variable-speed systems, we frequently recommend Rheem for its cold-climate performance and parts availability in the metro Atlanta area. We keep common parts for these brands in local stock, so a warranty part doesn’t mean a two-week wait while your family swelters. The right brand matters less than the right sizing and the right install. We’ll tell you plainly which equipment fits your house and your budget, and then we’ll put it in writing.
Common AC Installation Problems We See in Marietta Homes
These are the failures that separate a real Marietta installation from a box swap. We see all four every week, and they all share one root cause: whoever installed the last system never checked the ductwork or the load.
- New equipment dropped onto 1990s East Cobb duct systems. Houses along Murdock Road and East Piedmont Road were built with R-6 flex ducts in un-vented attics. After 25-30 years, the insulation collapses, the mastic seals crack, and static pressure climbs. A new coil on that ductwork runs loud, inefficient, and wet. We measure static pressure before we ever quote a changeout.
- 1960s west Marietta ranches with original galvanized trunks. The Lockheed-era homes near Austell Road and Whitlock Avenue often still carry the ducts installed when Bell Bomber workers first bought the houses. Those trunks have shifted, separated, and leaked for six decades. Latent heat removal never happens because the air isn’t reaching the rooms. Replacing the AC without fixing the ducts just gives you a more efficient machine pushing air into a crawlspace.
- Single-zone changeouts on multi-zone homes. A 4,000-square-foot two-story near Marietta Square gets a single-zone condenser installed because it’s cheaper. The long duct runs starve the upstairs, the system short-cycles, and the compressor dies early. We quote the job correctly or we don’t quote it at all.
- Skipped commissioning. The unit fires up, the tech feels cold air at the vent, and everyone calls it done. But refrigerant charge was never verified, thermostat staging was never calibrated, and airflow was never measured. The system runs at 70% of what you paid for. We commission every install with measurements, not guesses.

FAQs About AC Installation in Marietta
A full AC replacement in East Cobb commonly requires a Cobb County building permit, and if the duct system is being replaced or substantially modified, that permit includes a scheduled rough-in and final inspection before the walls or attic access close up. Cobb County’s building inspection department enforces this on every full system changeout and duct replacement. Contractors working across the line in Cherokee or Fulton County don’t face the same requirement on the same scope. It adds lead time and paperwork, which is honestly fine because the inspection exists to catch bad duct jobs. We pull the permit, schedule the inspection, and stay through the final approval. If you’re replacing a system in a 1990s East Cobb home off Murdock Road, expect the permit and inspection to be part of the written price. Call (747) 966-3037 for a fixed quote that includes all of it.
You can, but you shouldn’t. Those original galvanized trunks in Lockheed-era ranches have been leaking for decades. The seams have separated, the insulation is gone, and the ducts are pulling in crawlspace air that’s heavy with humidity and whatever lives under the house. A new AC on those ducts will cool a little better, but the latent heat removal will never happen because the airflow is bleeding into the crawlspace before it reaches the registers. You’ll spend $3,500-$7,500 on new equipment and still feel sticky. The honest recommendation is to replace or seal the duct system at the same time. We quote it as one job so the price is clear before you sign. Call (747) 966-3037 for an estimate that covers both the equipment and the ducts.
Because the system is removing sensible heat but not latent heat, and in west Marietta’s older ranches the cause is almost always undersized or leaky ductwork, not the thermostat. Marietta’s dewpoints sit in the low-to-mid 70s from June through September, which means the air carries a lot of moisture that a properly sized system should be removing. When the ducts leak or the equipment is oversized, the unit satisfies the thermostat too fast and shuts off before dehumidification happens. You feel cold, damp air instead of dry, comfortable air. The fix is a load calculation and duct inspection, not a lower thermostat setting. Call (747) 966-3037 and we’ll measure what’s actually happening in your house.
Yes, but it has to be sized and staged correctly. A properly sized heat pump with appropriately sized auxiliary strip heat can handle Marietta’s winter cold snaps. The sub-20°F nights near the Blue Ridge foothills are real, but they’re infrequent. For most of the winter, a heat pump runs far more efficiently than strip heat or even a gas furnace in many Marietta homes. The sweet spot for larger homes is a dual-fuel setup: a heat pump for mild and cool weather, a gas furnace for the genuine cold snaps. That’s a system we install regularly in East Cobb and homes around Marietta Square. Call (747) 966-3037 for a quote that compares heat pump versus dual-fuel for your specific house.
A proper replacement involves a room-by-room load calculation on each zone, a static pressure and duct leakage test on the existing duct system, and then either sealing or replacing the flex ducts before the new air handlers go in. We recently replaced a 26-year-old dual-zone Lennox air handler setup in an East Cobb subdivision off Murdock Road. The attic flex duct had collapsed insulation and the mastic seals were gone, pushing static pressure far outside the range a new evaporator coil would tolerate. After the load calculation, we upsized tonnage on the second zone, sealed the trunks, and commissioned both zones with refrigerant charge and thermostat calibration verified before we walked away. The homeowners stopped running the downstairs unit to cool the upstairs, and their summer indoor humidity finally matched what the original 1990s design promised on paper. That’s the standard, and it’s why a Cobb County permit usually accompanies this work. Call (747) 966-3037 and Luis Serrano will walk you through what your specific home needs.
If your AC is reaching the end of its life, or if your Marietta home has never quite held temperature or humidity the way it should, call (747) 966-3037 today. Estimates are free, the price is in writing before any work starts, and the 365-Day Done Right Promise means we stand behind every installation for a full year.
