Heat Pump Installation in Alpharetta - One Written Price, Rebates Handled

Trusted Heat Pump Installation for Alpharetta Homeowners

Heat pump installation in Alpharetta typically costs between $3,500 and $7,500 depending on system size, efficiency rating, and ductwork condition. Most replacements take one full day, and Dalton Heating & Air Alpharetta gives you a written price before any work begins. Marco Benitez leads a team that has installed heat pumps across Alpharetta, Milton, Duluth, and surrounding North Fulton communities since 2003 under The Garrison Standard. When your old system gives out in July or struggles through January nights, you need a crew that shows up, does the job by the book, and stands behind it for a full year. Call (229) 537-2086 and you’ll reach a live person, not a voicemail queue.

Mini Split Installation

Mini Split Installation in Alpharetta runs $3,500 – $7,500 for a complete ductless system, with single-zone setups landing on the lower end and multi-zone configurations with three or four indoor heads reaching the upper end. A mini split is a ductless heat pump: a slim outdoor condenser connected to wall-mounted indoor units by a small refrigerant line, which means no ductwork, no crawlspace work, and zoned temperature control room by room. Dalton Heating & Air Alpharetta handles the full install including the electrical circuit, refrigerant charge, and the 2-to-3-inch hole through the wall, then leaves the job site clean enough that you’d never know we were there.

Add-on Rooms Without New Ducts

Finished garages, sunrooms, basement buildouts, and attic offices in Alpharetta rarely have duct runs sized for them. A ductless unit gives that space its own thermostat and its own heat pump, without ripping into ceilings to add supply and return lines. We size the unit to the room’s square footage and window load, so it actually reaches set temperature instead of running constantly.

Zoned Comfort in Older Alpharetta Homes

Homes built in the 1980s and 1990s across North Fulton often have a single zone serving two stories, which means the upstairs runs warm all summer. A multi-zone mini split puts independent heads in the upstairs bedrooms while the existing system handles the main floor. You stop fighting one thermostat and start paying for only the cooling you actually use.

Heat Pump Maintenance

Heat Pump Maintenance in Alpharetta runs $80 – $200 for a full tune-up, and we recommend it twice a year: once before cooling season and once before heating season. Because a heat pump runs year-round instead of seasonally like a furnace or straight AC, its coils, reversing valve, and refrigerant charge take twice the wear. Dalton Heating & Air Alpharetta sends a background-checked, uniformed technician who works through a checklist: coil cleaning, refrigerant pressure check, reversing valve operation, thermostat calibration, condensate drain flush, and electrical connection torque.

Spring Cooling Preparation

Before Alpharetta’s humidity settles in around May, we check that the outdoor coil is clean enough to shed heat efficiently. A coil caked with pollen and cottonwood fuzz from spring makes the compressor work harder and shortens its life. We also verify the defrost cycle works, because a stuck reversing valve in summer means the system heats when you’re asking for cooling.

Fall Heating Verification

Before the first cold snap, we confirm the heat pump produces rated temperature rise across the indoor coil and that the auxiliary heat strips are staged correctly. In Alpharetta, winter temps routinely dip into the 20s, and the heat strips carry the load when the heat pump alone can’t keep up. We also check the drain pan and float switch so you don’t get a wet ceiling in January.

Geothermal Heat Pump Installation

Geothermal Heat Pump Installation in Alpharetta runs higher than an air-source system: most ground-loop installations land between $10,000 and $25,000 depending on loop configuration, soil conditions, and home size, though the indoor equipment itself typically falls in the $3,500 – $7,500 range. A geothermal heat pump – also called a ground-source heat pump – uses the earth’s stable temperature about six feet down instead of outdoor air. That means consistent efficiency whether it’s 95 degrees in August or 18 degrees in January. Dalton Heating & Air Alpharetta coordinates the loop field design, drilling or trenching, and the indoor heat pump unit so everything is sized and commissioned as one system.

Vertical Loop Fields for Alpharetta Lots

Most lots in Alpharetta don’t have the open acreage for a horizontal loop field, so vertical boreholes are the standard approach. We work with licensed drilling contractors who log the soil and rock conditions, because the borehole depth and grout specification directly affect how well the loop absorbs and rejects heat. A poorly grouted borehole loses efficiency you’ll pay for every month for 20 years.

When the Ground Loop Outlasts the Unit

The polyethylene loop field in the ground typically carries a 50-year manufacturer warranty. The indoor heat pump itself runs 20 to 25 years, which means you’ll likely replace the mechanical unit once during the loop’s lifetime. We design the indoor equipment connection points so a future swap-out is straightforward: accessible service valves, properly documented loop flow rates, and a clean mechanical room layout.

Ductless Heat Pump Installation

Ductless Heat Pump Installation in Alpharetta falls in the $3,500 – $7,500 range, with the final number driven by how many indoor heads you need and whether you’re heating one room or a whole addition. Ductless heat pumps move heat through refrigerant lines instead of air ducts, which eliminates duct leakage entirely – and in Georgia’s humid climate, leaky ducts also pull in attic air that makes your system work harder. Dalton Heating & Air Alpharetta installs ductless systems from Lennox, Goodman, and Rheem, with the line set run cleanly along exterior walls and the condensate drained properly so there’s no staining on your siding.

Single Zone Versus Multi Zone

A single-zone ductless system serves one indoor head from one outdoor unit. Multi-zone systems branch from one outdoor unit to as many as five indoor heads, each with its own thermostat. The equipment cost climbs with each head, but the labor for the outdoor unit and electrical work happens once, so multi-zone systems often deliver better overall value per room.

Placement Matters More Than Brand

A ductless head mounted on the wrong wall – blasting the bed, hidden behind a beam, or facing a big west-facing window – will never feel comfortable no matter which manufacturer made it. We walk the room with you before we drill anything, measure the throw distance and airflow pattern, and mark the exact mounting location on the wall. You see where the unit goes before the hole gets cut.

Heat Pump Service

Heat Pump Service in Alpharetta for repairs runs $150 – $650 depending on the part that failed and how long the diagnostic takes. When a heat pump stops heating or cooling, the common culprits are the reversing valve, the defrost control board, a failed capacitor, or a refrigerant leak at a flare fitting. Dalton Heating & Air Alpharetta repairs all nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The diagnostic fee is credited toward the repair if you approve the work, and every repair carries a written guarantee for a full year – if it fails in that window, we return at no charge.

Common Heat Pump Failure Points

The reversing valve is what lets a heat pump switch between cooling and heating, and when it sticks, the system runs backward regardless of what the thermostat says. Capacitors fail gradually until the compressor or fan won’t start on the hottest afternoons. Refrigerant leaks at the flare fittings where the line set connects to the outdoor unit are the most common leak point we find on systems that are five to eight years old.

Same-Day Visits When the System Fails

In Alpharetta’s July heat, a dead heat pump turns a house into a health risk within hours. We keep common capacitors, contactors, defrost boards, and reversing valves stocked on our trucks so the most frequent failures get fixed on the first visit. A live person answers the phone 24/7, and we’ll tell you the current dispatch window before you hang up.

Heat Pump Replacement

Heat Pump Replacement in Alpharetta costs $3,500 – $7,500 for most homes, and the decision to replace usually comes down to three things: the age of the existing system, the cost of the current repair, and what refrigerant the old system uses. If your heat pump is 12 years old or older and the compressor fails, we’ll quote you the repair price and the replacement price side by side, in writing, and let you decide. Dalton Heating & Air Alpharetta replaces systems from Lennox, Goodman, Rheem, York, and every other major brand, and the installation includes a full-year written guarantee plus the 365-Day Done Right Promise.

R-22 Phaseout Means Replacement Is Often Smarter

If your existing heat pump was built before 2010, it likely runs on R-22 refrigerant, which has been phased out of production. A refrigerant recharge on an R-22 system now costs several hundred dollars for the refrigerant alone, and that’s money going into a system that’s already past its design life. Most Alpharetta homeowners we talk to would rather put that money toward a new R-410A or R-454B system with a fresh parts warranty.

Load Calculation Before Any Equipment Order

We don’t replace a 3-ton unit with another 3-ton unit because “that’s what was there.” We run a Manual J load calculation on every replacement, measuring window area, insulation levels, ceiling height, and orientation to size the new system properly. An oversized heat pump short-cycles, doesn’t dehumidify, and wears out its compressor early. An undersized one runs constantly and still doesn’t hold temperature on extreme days.

Brands We Service

Dalton Heating & Air Alpharetta is factory-trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock OEM parts for Lennox and Goodman units on our trucks, because those two brands represent a large share of the systems installed across North Fulton, and same-day repair depends on having the right capacitor or defrost board when we pull up.

We’ve installed and serviced Rheem heat pumps for over two decades, and their defrost control logic and reversing valve placement are second nature to our technicians. York systems, with their particular control board and diagnostic code structure, are another brand we see regularly in Alpharetta neighborhoods. Whether you have a Lennox, Goodman, Rheem, York, or any other make, we can diagnose it, fix it, replace it, and stand behind the work in writing.

Signs You Need a Pro Right Now

• Your heat pump runs but doesn’t change the temperature. If the system blows air that’s close to room temperature in cooling mode, the compressor may have failed or the reversing valve may be stuck. Running it in this condition wastes power and can cause further damage to the compressor, which is the most expensive component to replace.
• Ice forms on the outdoor unit in summer. Frost or solid ice on the outdoor coil during cooling season means the coil isn’t absorbing heat properly – typically low refrigerant, a dirty coil, or restricted airflow. Letting it run iced up can send liquid refrigerant back to the compressor, which destroys it.
• The system switches to auxiliary heat constantly. If your thermostat shows “AUX” or “EM heat” during mild Alpharetta winter weather, the heat pump isn’t producing enough heat on its own. The electric heat strips cost far more to run than the heat pump itself, so your power bill becomes the diagnostic clue.
• Loud grinding, squealing, or banging from the outdoor unit. A grinding sound usually means a compressor or fan motor bearing is failing. A bang or rattle often means a broken compressor mount or a failed internal component. These sounds don’t fix themselves, and the compressor is a sealed unit – once it fails, you’re looking at replacement-level money.
• Water pooling around the indoor air handler. A clogged condensate drain or a cracked drain pan sends water onto your floor or ceiling instead of outside. In Alpharetta’s humid summers, that water can cause mold and drywall damage within days, not weeks.

Our Process, Step by Step

1. 1
   You call, a person answers. When you call (229) 537-2086, a live dispatcher answers 24/7. You’ll get a real arrival window that day – usually a two-hour block – and the tech’s name before they show up. No call center script, no “someone will call you back.”
2. 2
   We show up and inspect. The technician arrives in a marked van, in uniform, and walks the full system with you. We check the existing heat pump, the ductwork if you have it, the electrical service, and the thermostat wiring. We measure for a Manual J load calculation on every replacement or new install, so the size we quote is the size the house needs, not a guess based on square footage alone.
3. 3
   You get a written price. Before any work starts, you receive the complete cost on paper: equipment, labor, electrical, any duct modifications, disposal, and tax. That number doesn’t change when the job is done. The Garrison Code requires it, and we’ve operated that way since 2003.
4. 4
   Installation done by the book. We recover the old refrigerant properly, braze the new line set under nitrogen purge to prevent oxidation inside the copper, pressure-test with nitrogen, evacuate to a deep vacuum, and weigh in the refrigerant to the manufacturer’s exact charge. The system gets commissioned with startup data recorded: pressures, temperatures, airflow, and voltage.
5. 5
   Cleanup, walkthrough, and paperwork. We leave the work area cleaner than we found it, haul away the old equipment, and walk you through the new thermostat programming and filter locations. You get the written guarantee for a full year, the manufacturer warranty registration, and a summary of what was installed and why.
