AfterFast, Reliable Heat Pump Installation Across Marietta
Heat pump installation in Marietta, GA typically costs between $3,500 and $7,500 for a standard single-zone split system, and most jobs in Marietta are completed in one day once equipment arrives. We serve every zip code in Marietta, from Powder Springs Road up to Sandy Plains and across to the Whitlock Avenue corridor. If your heat pump is short-cycling, blowing warm air in cooling mode, or running up electric bills that keep climbing, call Dalton Heating & Air at (361) 306-9515. We give you a written price before any work starts, and we stick to it.
Why Dalton Heating & Air Is Marietta’s Preferred Heat Pump Installation Company
Homeowners in Marietta call us because they’re done with technicians who guess, rush, and leave the job half-finished. We operate under The Garrison Standard, a set of rules that has governed how our company works since 2003. Every job gets a written price before work begins. Every repair comes with a written guarantee for a full year. If the work doesn’t hold, we come back at no charge. That’s not a promotion. That’s the way we’ve run every single call in Marietta.
Marco Benitez leads our Marietta install crews. When you book a heat pump installation, you’ll know exactly who is coming: a background-checked, uniformed technician who is factory-trained on the major brands we service. We answer the phone with a live person 24 hours a day, seven days a week. Not a callback window. Someone picks up, takes your information, and gets your job scheduled.
Our service to Marietta is coordinated from our Atlanta metro office, but the crews who show up at your door work this area every week. They know the housing stock, the electrical panels common in older east Marietta homes, and the duct issues we see in split-levels on the west side. Local knowledge saves you money because we don’t spend the first hour figuring out your house.
Geothermal Heat Pump Installation in Marietta
Geothermal Heat Pump Installation in Marietta is a different animal from a standard split system, and it rewards homeowners who understand the local ground before they dig. These systems pull heat from the earth instead of the air, running water or refrigerant through buried loops that stay at a roughly constant temperature year-round. In Marietta, that steadiness translates to real efficiency gains during our long, humid cooling season when air-source units lose capacity as outdoor temperatures climb into the high 90s.
One thing most metro Atlanta installers miss here: Marietta’s red-clay soil holds moisture differently than the sandy or rocky soils you see elsewhere. Our spring downpours saturate that clay and it stays wet for weeks. When we size a geothermal loop field in Marietta, we tune the loop-field sizing to saturated-soil conductivity rather than dry-soil defaults. That matters because wet clay transfers heat better than dry clay. A loop field sized for dry-soil assumptions often runs shorter and hotter than it should, which cuts efficiency and shortens equipment life. We’ve corrected several of those mistakes in Marietta and Roswell homes where a previous installer used generic sizing software.
Sizing and Excavation
Geothermal work requires either horizontal trenches or vertical boreholes, depending on lot size. Marietta lots in subdivisions near Kennesaw Mountain tend to be compact, so vertical loops usually make more sense. We walk the property, check access for drilling equipment, and give you a written price that covers excavation, loop installation, grouting, and the indoor heat pump package.
What a Geothermal Install Costs Here
A full geothermal heat pump installation in Marietta generally starts at the upper end of the $3,500 – $7,500 range for the indoor unit alone, but loop-field work adds significant cost depending on depth and soil conditions. We write the entire scope and price down before digging starts. No line items that materialize later. No “soil difficulty” surcharge appearing after the drill rig arrives.
Ductless Heat Pump Installation in Marietta
Ductless Heat Pump Installation in Marietta is often the smartest answer for older homes that never had ductwork, for additions, or for specific rooms that run hot and cold. Ductless mini splits mount on a wall or ceiling and connect through a small line set to an outdoor condenser. They deliver conditioned air directly to the room, which means you don’t pay to push air through thirty-year-old duct runs that leak 20 – 30% of what they carry.
That leak problem is real in Marietta’s pre-1990s housing stock. Ducts buried in crawl spaces and attics have loose joints, gaps, and sometimes actual holes from past renovations. A ductless heat pump sidesteps all of that. For a sunroom off the back of a house near Whitlock Avenue, a finished garage off Sandy Plains Road, or a mother-in-law suite near Marietta Square, a ductless install often beats extending existing ductwork on both price and comfort.
Multi-Room Ductless Systems
One outdoor unit can feed up to four or five indoor heads, each with its own thermostat. That lets you cool the upstairs bedrooms at night without cooling the whole first floor. We size each head with a room-by-room load calculation so you don’t end up with an oversized unit cycling on and off and leaving humidity high.
Ductless Costs in Marietta
A single-zone ductless heat pump install in Marietta typically runs $3,500 – $7,500, with multi-zone layouts higher depending on the number of heads and line-set length. We quote the full amount in writing, including electrical, line-set cover, and any wall or trim work.
Trusted Brands We Service in Marietta
Our Marietta technicians are factory-trained on the systems most common in this market: Goodman, Rheem, York, and Daikin. We stock common parts for these brands locally, which speeds up repairs and keeps installation timelines short. If your existing unit is a Carrier, Trane, Lennox, or Bryant, we service and replace those too. You don’t have to purchase from us to call us. If you’re replacing a failed unit, we help you compare equipment by actual SEER2 rating, not just brand name. A properly sized Goodman will outperform a badly installed top-tier brand every time. Heat Pump Installation done right starts with the load calculation, not the label on the box.
Common Heat Pump Installation Problems We See in Marietta Homes
- Oversized units short-cycling because installers skipped the load calculation. Some contractors guess tonnage from square footage and round up. An oversized heat pump cools the air fast, shuts off, and never runs long enough to remove humidity. You end up with a cold, clammy house and a bigger electric bill. We run a manual J load calculation on every install we quote in Marietta.
- Old duct runs in pre-1990s homes leak 20 – 30% of conditioned air. Even a correctly rated SEER2 heat pump underperforms when the ducts bleed conditioned air into an attic or crawl space. The blower motor works harder, the system runs longer, and you pay for air that never reaches the room. We test static pressure and duct leakage before recommending a replacement.
- Condensate drain pans and lines grow algae during Marietta’s humid springs. Standing water plus warm air equals biological growth, and when that growth blocks the drain line, water backs up and either trips a float switch or damages the ceiling below an attic unit. Regular maintenance keeps those lines clear.
- Refrigerant charge is off after install because techs don’t weigh it in. A heat pump’s efficiency numbers assume an exact refrigerant charge. If the tech charges by feel or pressure alone, the charge is wrong. You get high bills, poor dehumidification, and premature compressor failure. We weigh refrigerant in to the manufacturer’s specification and record it on your paperwork.

FAQs About Heat Pump Installation in Marietta
Replace the unit when the compressor fails, the system is over 12 – 15 years old and leaking refrigerant, or the repair estimate exceeds roughly half the cost of a new system. Repair makes sense for capacitor failures, contactor issues, and other component-level problems under $650. We’ll give you a written diagnosis and let you decide. If repair is the right call, you get our written one-year guarantee. Call (361) 306-9515 for an honest assessment.
Most single-family Marietta homes need between 2 and 4 tons, but the only way to know is a manual J load calculation that accounts for square footage, ceiling height, window area, insulation levels, and orientation. Guessing tonnage from square footage produces oversized units that short-cycle and leave humidity high. We run the load calculation on every install and keep the results on file.
SEER2 is the updated efficiency rating that replaced SEER in 2023. It measures cooling output per watt of electricity under a more realistic test procedure that accounts for static pressure in ductwork. A 16-SEER2 heat pump uses roughly 10 – 15% less electricity than a 14-SEER2 unit under the same conditions. In Marietta, where electric rates run above the national average, that difference shows up on every summer bill. Call us at (361) 306-9515 and we’ll calculate payback on the actual efficiency numbers for your home.
Yes. Ductless mini splits work well in Marietta homes with no ductwork, additions, garages, sunrooms, or rooms that always run hotter or colder than the rest of the house. A single-zone ductless install in Marietta typically runs $3,500 – $7,500, and multi-zone systems cost more depending on the number of indoor heads. We quote the full job in writing before work begins.
Twice a year. Once in spring before cooling season, once in fall before heating season. Marietta’s humid springs drop pollen, red clay dust, and biological growth into outdoor coils and drain pans, and our long cooling season puts real hours on the compressor. A tune-up runs $80 – $200 and catches problems before they become emergency repairs. Call (361) 306-9515 to get on the schedule.
