Get your free estimateFast, Reliable Heat Pump Installation Across Doraville
A full heat pump installation in Doraville runs $3,500 to $7,500, depending on system size, ductwork condition, and whether we’re correcting existing airflow problems. Most Doraville homes we work in were built between 1960 and 1980, which means the heat pump isn’t just swapping out – it’s often paired with return relocation and duct sealing to actually work in a muggy Georgia summer. If you’re on Buford Highway near the GM plant corridor or back in the neighborhoods off Tilly Mill Road, we know these houses. Call (229) 537-2086 for a written estimate before any work starts.
Why Dalton Heating & Air Alpharetta Is Doraville’s Preferred Heat Pump Installation Company
Dalton Heating & Air Alpharetta operates under The Garrison Standard, which has governed how we work since 2003. That’s not a marketing line. It means every Doraville job gets a written price before we touch the system, a written guarantee on the work, and a crew that arrives in the window we gave you. Marco Benitez runs our installation operations, and he’s the kind of manager who rides out to Doraville himself when a job has unusual ductwork or a crawlspace that needs attention.
Doraville houses are not Alpharetta houses. The 1960s and 70s ranches and split-levels here have original duct runs, low-wall returns, and crawlspaces that hold humidity. A crew that mostly does new construction in Duluth will misread these homes. Our technicians work in Doraville regularly, so they know what a 1972 split-level on a crawlspace needs before they open the blower cabinet. That’s the difference between a system that holds 50% humidity and one that short-cycles every August afternoon.
When you call Dalton, a live person answers. Every time. Not a voicemail queue or a callback window. If your heat pump fails during a Doraville summer, you’re not waiting until Monday to hear back. The Garrison Code binds every location: show up inside the stated window, price in writing, do the job by the book, leave the site clean, stand behind it for a full year.
Styles & brands we work with
Heat Pump Maintenance in Doraville
Heat Pump Maintenance in Doraville means more than a quick filter swap. Given the humidity here, a maintenance visit has to check the evaporator coil for freeze-up conditions, measure static pressure across the ductwork, and verify the refrigerant charge matches the manufacturer’s spec. Homes off Winters Chapel Road or in the Huntley Hills area have duct systems that were marginal when new, and forty years of settling hasn’t improved them. That’s why our tune-ups are priced from $80 to $200 and always include a written report of what we found, not a verbal summary at the door.
Coil, Charge, and Airflow Check
A Doraville heat pump tune-up should always start with static pressure. High static pressure means your blower motor is working against a duct system that’s too small or too leaky, and that’s what kills compressors early. We check the evaporator coil for dust, mold, or ice and measure the refrigerant charge against the manufacturer’s SEER2-rated specification.
Duct Leak and Return Grille Inspection
We look at how the return side of the system is pulling air. Many Doraville ranches have low-wall returns that draw from the worst part of the house: hot, humid air near the floor. During summer, this can starve the coil of enough airflow to keep it above freezing. We’ll tell you if your return needs to move higher or get enlarged before a real problem develops.
Geothermal Heat Pump Installation in Doraville
Geothermal Heat Pump Installation in Doraville uses the stable ground temperature below the frost line to heat and cool your home, and the upfront cost runs at the top end of the installation range, starting around $7,500 and increasing with loop length and drilling conditions. Doraville’s soil mix – red clay over weathered rock – makes horizontal loops feasible on larger lots, while smaller lots near Buford Highway often call for vertical boring. The appeal is clear: a geothermal unit doesn’t fight 95-degree air to reject heat the way an air-source unit does, which matters through Doraville’s long cooling season.
Ground Loop Sizing for Doraville Lots
The loop field has to match the heating and cooling load of the house. An undersized loop freezes the ground around the pipes and kills efficiency. An oversized loop wastes money. We calculate the load from the house’s actual construction, not a rule of thumb, and Doraville’s older homes need that calculation done right.
Why Geothermal Works With Humid Summers
Because the ground loop rejects heat more steadily, a geothermal system holds indoor humidity tighter than an air-source unit through July and August. That’s a big deal in a house where the existing ducts leak and the return pulls humid crawlspace air. The system’s dehumidification is only as good as the ductwork, so we verify airflow before we commission the unit.
Trusted Brands We Service in Doraville
Our factory-trained technicians service the major residential brands most common in Doraville homes, including Lennox, Goodman, Rheem, and York. We keep replacement parts stocked in local supply warehouses for fast turnaround, so when a York board or a Goodman blower motor fails, our Doraville customers are not waiting days for shipping. The brand on the cabinet matters less than the quality of the install, the ductwork behind it, and the charge we put in it – but we’re trained to work on them all by the book.
Common Heat Pump Installation Problems We See in Doraville Homes
- Undersized ductwork and high static pressure. The original ducts in 1960s-70s Doraville homes were sized for smaller heating loads, not modern heat pumps. High static pressure strains the blower motor and leads to premature compressor failure.
- Low-wall return grilles pulling humid crawlspace air. Many ranches off Shallowford Road have returns near the floor that ingest the muggiest air in the house. The evaporator coil freezes, and repeated freeze-thaw cycles cause capacitor failures.
- Oversized units short-cycling in tightly sealed homes. A too-big heat pump cools the air fast but never runs long enough to remove humidity. In Doraville split-levels with new windows and added insulation, that means mold growth and a clammy feel even at 72 degrees.
- Leaky ductwork in unconditioned crawlspaces. Original duct runs under Doraville homes lose conditioned air into the crawlspace. The system works harder, humidity stays high, and the electric bill climbs without cooling the rooms you live in.

FAQs About Heat Pump Installation in Doraville
Yes, if the return isn’t addressed. Low-wall returns pull the most humid air in the house, which can starve the evaporator coil of airflow and cause ice to form. Many Doraville ranches need the return moved higher on the wall or enlarged before a new heat pump works correctly. Call (229) 537-2086 and we’ll check static pressure before recommending any new equipment.
You need a full load calculation – Manual J – that accounts for exposed walls, window area, insulation levels, and the house’s orientation. Doraville homes on open lots lose more heat in winter and gain more in summer than sheltered homes, so a rule-of-thumb sizing will be wrong. Wrong sizing means short-cycling and high humidity. We do the calculation for every installation at no charge.
A properly sized variable-speed heat pump with sealed ductwork can hold Doraville homes at 50% humidity or below through most of the summer. A whole-home dehumidifier helps in homes with heavily shaded lots, crawlspace moisture issues, or when the house is oversized for the cooling load. We’ll tell you if you need one after measuring humidity levels and duct leakage.
The charge must match the manufacturer’s specifications for the specific outdoor unit and line set length. There is no “Doraville charge” – but Georgia’s humidity means an overcharged or undercharged system will show up as poor dehumidification or coil freezing. We weigh in refrigerant by the manufacturer’s chart and verify subcooling and superheat before we leave.
Yes, a ductless mini-split heat pump handles a workshop or outbuilding without any ductwork. These units hang on the wall, connect to a small outdoor condensing unit with a line set through the wall, and provide both heating and cooling. For a 400-600 square foot workshop, expect to spend $3,500 to $5,500 installed. Call (229) 537-2086 and we’ll spec it to the building’s actual heat load.
