AfterFast, Reliable Heat Pump Installation Across Dunwoody
Heat pump installation in Dunwoody typically runs $3,500 – $7,500 for a complete system, and most jobs are finished in one to two days. If your current heat pump is over 12 years old, short-cycling, or struggling to hold temperature in Dunwoody’s muggy summers and cold snaps, the math usually favors replacement over another repair. We’re Dalton Heating & Air, a Garrison Partners company operating under The Garrison Standard since 2003, and we serve Dunwoody with written pricing before any work starts. Call (361) 306-9515 for a free estimate on a properly sized heat pump for your home.
Dunwoody has a particular kind of housing stock. Tree-heavy lots, mature 1970s – 90s subdivisions, and a mix of original builds and additions mean every heat pump job here needs a measured approach, not a quick tonnage swap. We know the area. We know the homes. And we know that no two Dunwoody houses heat or cool exactly the same way, which is why we start every installation with a room-by-room load calculation and a static pressure check before we ever quote a unit.
Why Dalton Heating & Air Is Dunwoody’s Preferred Heat Pump Installation Company
The Garrison Code is not a brochure. It’s a set of non-negotiable rules every Dalton location is bound to: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. Dunwoody homeowners have called us after crews no-showed, after the quote changed at the door, after the job was left half-finished. We hear it regularly. And we run a different shop.
Our techs are background-checked and uniformed, so you know who’s coming before they get to your door off Ashford Dunwoody Road or up near the Dunwoody Country Club. Calls are answered by a live person, 24/7. We do not route you to a voicemail queue or a callback window. And every installation includes the 365-Day Done Right Promise. If it’s not done right, we make it right. Full year. That’s the whole point.
Marco Benitez leads our team. He sets the expectation that every Dunwoody job gets written pricing, a written guarantee, and a free return visit if anything fails within the guarantee period. That’s the standard. Not an upgrade.
We are part of a network held to The Garrison Standard on every job since 2003. Dispatch and scheduling are coordinated from the brand’s Atlanta office, but the crews working Dunwoody live and work right here in the metro. We serve all of Dunwoody, from the Perimeter Center area to the neighborhoods off Chamblee Dunwoody Road, and we carry parts for nine major residential HVAC brands, so delays waiting on a distributor are rare.
Mini Split Installation in Dunwoody
Mini Split Installation in Dunwoody is often the right call for sunrooms, converted garages, additions, or upstairs rooms that never quite reach set temperature with the main system. A ductless mini split pairs an outdoor condenser with one or more wall-mounted indoor units, connected by a small refrigerant line set through a three-inch wall opening. No ductwork. No demolition. For a single-zone mini split install, Dunwoody homeowners should expect roughly $3,500 – $7,500 depending on zone count, capacity, and whether the electrical panel needs a dedicated circuit.
Dunwoody’s mix of original 1960s – 1980s ranches and split-levels plus newer additions means a lot of homes have one or two rooms that the original duct design never reached properly. Rather than ripping apart ceilings, our Heat Pump Installation team can size a ductless unit for just that zone.
When Ductless Beats Ducted in Dunwoody
Older Dunwoody neighborhoods off Mount Vernon Road and along Tilly Mill Road have homes where existing ductwork is undersized for modern equipment. A mini split solves that without touching a single duct. It also gives you independent temperature control per zone, which matters when a west-facing bedroom bakes in August while the rest of the house stays comfortable.
Load Calculation Still Applies to Mini Splits
Even ductless systems get sized with a room-by-room load calculation. Oversizing a mini split causes short cycling and poor dehumidification, and in Dunwoody’s humid climate, that means a clammy room that feels cool but never dry. We measure the space, the window area, the exposure, and the insulation before we recommend tonnage.
Heat Pump Maintenance in Dunwoody
Heat Pump Maintenance in Dunwoody runs $80 – $200 for a tune-up and should happen twice a year, once before cooling season and once before heating season. A heat pump works year-round, so it accumulates more runtime than a straight AC or furnace. In Dunwoody’s tree-heavy lots, the condenser coil collects leaves, pollen, and pine needles quickly, which restricts airflow and drives up head pressure. A maintenance visit includes coil cleaning, capacitor testing, refrigerant check, thermostat calibration, and a static pressure reading.
What a Tune-Up Catches Before It Bites
A weak capacitor is one of the most common summer AC failures, and a five-minute test catches it before the compressor pays the price. In heat pump mode, that same weak part can kill heating in January. We test every capacitor on every maintenance call, and we report the findings in writing, including the actual measured readings, not just a checkbox.
Why Twice a Year in Dunwoody Specifically
Dunwoody’s weather swings are the problem. Cool humid springs, brutal July heat, and January nights below freezing all stress the same refrigerant circuit. A heat pump that runs in cooling mode in August needs to reverse and hold heat in January. Twice-yearly checks keep both modes dialed in, which extends the compressor’s life and keeps the electricity bill steady instead of spiking.
Our technicians are paid by the hour, not by what they sell. If a maintenance call finds nothing wrong, we tell you that. The written report is designed to help you decide what needs attention now and what can wait, and the price is in writing before any repair work begins.
Trusted Brands We Service in Dunwoody
We service and install all major residential heat pump brands, and we stock parts for Trane, Lennox, Goodman, and Rheem locally for Dunwoody customers. That means when a Trane compressor contactor fails or a Rheem defrost control board shorts, we are usually completing the repair the same day rather than waiting on an Atlanta warehouse run. Our techs are factory-trained on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In practice, that means we’re not guessing at wiring diagrams or guessing at sequence of operation. We know the equipment.
For Dunwoody homes with mixed systems, like a newer condenser paired with an older air handler off a 1980s split-level, we’ll give you honest guidance on whether to match brands or repair the existing configuration. Some combinations work. Some are a reliability headache. We’ll tell you which one you have, in plain terms.
Common Heat Pump Installation Problems We See in Dunwoody Homes
- Oversized tonnage installed by rule of thumb. Dunwoody’s mix of 1960s – 90s homes has wildly different envelope tightness. An oversized heat pump short-cycles, wrecks humidity control, and wears out the compressor early. We see units that are a full ton too large for the house they’re cooling.
- Leaf-packed condenser coils from mature tree canopy. Restricted airflow drives high head pressure and false defrost cycles, making a heat pump look “broken” when it just needs a proper coil cleaning and static pressure check. The tech who says “replace it” without checking static pressure first is guessing.
- Failed capacitor or blower motor on older air handlers. A weak capacitor is one of the most common summer AC failures and a five-minute test catches it before the compressor pays the price. In heat pump mode, the same weak part can kill heating in January, usually on the coldest night.
- Improper charge from the last install. Dunwoody’s heat pump systems operate across a wide temperature range, and if refrigerant charge was set by “beer can cold” instead of superheat and subcooling, efficiency and capacity both suffer. We dial charge with digital manifolds and micron gauges on every install.

FAQs About Heat Pump Installation in Dunwoody
If your heat pump is under 10 years old and the failure is a single component like a capacitor, contactor, or defrost board, repair it. Repairs in Dunwoody run $150 – $650 for AC-side fixes and $150 – $700 for furnace and heat pump repairs. If the compressor has failed, the unit is over 12 years old, or it uses R-22 refrigerant that’s leaking, replacement is the honest answer. A new heat pump in Dunwoody runs $3,500 – $7,500. Call (361) 306-9515 and we’ll help you weigh the real numbers for your specific system.
A load calculation, a proper Manual J, measures every room’s window area, ceiling height, insulation levels, and sun exposure to size the unit to the actual heating and cooling load. In Dunwoody’s mixed housing stock, that often means the correct heat pump is a half-ton or even a full ton smaller than what a rule-of-thumb tech would quote. The smaller unit runs longer cycles, removes more humidity, and costs less to run. Oversized tonnage is the most common installation error we see in Dunwoody.
SEER2 is the updated efficiency rating standard for cooling. A heat pump rated SEER2 15 will use noticeably less electricity than a 12-year-old unit rated SEER1 10 or 11, even at the same thermostat setting. In Dunwoody, where a heat pump runs both cooling and heating across most of the year, the annual savings from a SEER2 15 or 16 heat pump can be several hundred dollars depending on runtime and Georgia Power’s current rates. We can show you the efficiency math for your specific home during the quote.
If your existing ductwork does not reach the addition and the room is under 1,000 square feet, a mini split usually makes more sense than tearing into ceilings. A ductless install in Dunwoody runs $3,500 – $7,500 depending on zone count and capacity. If the addition is large enough or you’re replacing the main system anyway, a properly sized full heat pump with new duct runs may be the better investment. We’ll tell you the honest answer after seeing the space.
Twice a year, before cooling season and before heating season. Dunwoody’s tree-heavy lots mean condenser coils clog faster than in open subdivisions, and a clogged coil costs you money every month it runs restricted. A maintenance visit here runs $80 – $200 and includes coil cleaning, capacitor test, refrigerant check, and a written report. Skip it for two years and you’ll usually find a fixable problem that became an expensive one.
