Fast, Reliable Heat Pump Installation Across Grayson
Heat pump installation in Grayson typically runs $3,500 to $7,500 for a full-system replacement at like-for-like tonnage, and most jobs are done in a single day once equipment is ordered. Grayson homeowners call us because their 1990s or early-2000s builder-grade heat pump is failing, or because they added a bonus room or finished the basement and the original system never kept up. When you call Dalton Heating & Air at (361) 306-9515, a real person answers, we give you a written price before any work starts, and the installation is backed by our 365-Day Done Right Promise. That’s how we’ve operated since 2003 under The Garrison Standard.
Why Dalton Heating & Air Is Grayson’s Preferred Heat Pump Installation Company
Grayson sits right on the Gwinnett/DeKalb line, and a lot of what we see here is the same: 1990s to 2000s subdivisions full of original equipment that is now at end of life. Homeowners in Grayson know their neighbors talk, and the word around Grayson is that we show up inside the stated window, put the price in writing before we touch anything, and leave the site clean. That is The Garrison Code, and every Dalton technician is background-checked, uniformed, and held to it on every job.
Marco Benitez leads our team and sets the tone for how we work in Grayson: no surprises at the door, no pressure to buy, and a written guarantee on every repair. Whether it’s a service call in a subdivision off Rosebud Road or a full system replacement near Grayson High School, the same standard applies. You know who is coming before they arrive, and you know the price before they start.
Heat Pump Service in Grayson
Heat Pump Service in Grayson usually starts with a system that is not heating or cooling the way it did last season. Maybe the outside unit runs constantly in July, or the house feels muggy even when the thermostat says 72. A service call in Grayson runs $150 to $650 depending on the part, and the first thing our technicians do is put eyes on the whole system, not just the symptom. They are factory-trained on nine major residential HVAC brands, including Rheem and Daikin, which are common in Grayson homes.
Diagnostics and repair
We trace the issue before we quote a fix. On a heat pump, that means checking the reversing valve, the compressor, the defrost board, and the refrigerant charge. If we find a bad capacitor or a leaking coil, you get a written price before the repair starts, and the repair is guaranteed in writing for a full year. If the work does not hold, we return at no charge.
Tune-ups and seasonal prep
A pre-season tune-up in Grayson runs $80 to $200 and catches the small things before they become a no-heat call in January or a no-cool call in July. We clean the coils, check the charge, test the reversing valve, and give you a written report of what we found and what can wait. We are not paid on what we sell, so the report is straight information, not a sales pitch.
Heat Pump Replacement in Grayson
Heat Pump Replacement in Grayson is the decision point where the math matters. If your existing system is more than 12 to 15 years old, uses R-22 refrigerant, or has needed two or more major repairs in the last two years, replacing it with a new high-efficiency heat pump usually makes more sense than continuing to patch it. Full replacement in Grayson runs $3,500 to $7,500 for like-for-like tonnage, and we give you a fixed written price, a set install date, and we handle the rebate and financing paperwork.
Whole-house replacement vs. adding a unit
In Grayson, the real question is often whether to replace just the main system or to address both the main heat pump and the later-added garage or bonus-room unit. We do not assume the original tonnage was correct. We run a load calculation on the whole house, including any finished basement or bonus room, and size the new system to the actual building, not the builder’s original estimate.
Efficiency and the SEER2 rating
Since 2023, new heat pumps sold in Georgia carry a SEER2 rating. The higher the number, the less electricity the system uses to produce the same amount of heating or cooling. In Grayson’s climate, moving from an old 10 SEER heat pump to a 16 or 17 SEER2 unit can cut the heating and cooling portion of your bill noticeably, and we will show you the estimated difference on your own square footage before you sign anything.
Trusted Brands We Service in Grayson
Dalton Heating & Air is factory-trained to install and service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Grayson customers, and when a part is not on the truck, we can usually source it same-day from our local supply houses. That means less downtime when our Heat Pump Installation team is already scheduled in the Grayson area.
Common Heat Pump Installation Problems We See in Grayson Homes
- Builder-grade tonnage that was never load-calculated. A lot of Grayson’s 1990s and 2000s subdivisions were built fast, and the original heat pump was sized by rule of thumb, not by measurement. Add a finished bonus room or basement, and the system short-cycles, the evaporator coil ices over in shoulder season, and the compressor wears out early.
- R-22 era condensers that can’t take a modern refrigerant charge. Older Grayson subdivisions still have heat pumps running on R-22, which is being phased out. These units quietly lose capacity for years before the compressor finally quits, and they cannot simply be topped off with a modern refrigerant without a full conversion or replacement.
- Duct static pressure that chokes once a second unit is added. The original duct design worked for one system. Add a separate heat pump for a bonus room without resizing the return, and both systems struggle. Static pressure climbs, airflow drops, and efficiency ratings on paper never show up on the bill.
- Short-cycling garage and bonus-room mini splits. We regularly see Grayson homes where the over-garage bonus room got its own undersized or oversized unit that never ran right. It’s usually a sizing problem, not a brand problem, and it gets fixed with a proper load calculation, not another guess.
One job, for example. Last fall we replaced a locked-up Carrier heat pump at a house off Pine Grove Road in the Grayson area, where the bonus room over the garage had its own 1.5-ton unit that short-cycled all summer. We ran a proper load calculation on the whole house, found the main system was oversized by a ton, and installed a matched Carrier variable-speed heat pump paired with the existing mini split so both stages tracked the actual square footage instead of the builder’s guess. That is what Grayson homes need: right-sizing against the house as it actually stands, not the house as it was built.

FAQs About Heat Pump Installation in Grayson
Yes, and that is a common job in Grayson. We replace the main heat pump, but before we order equipment we run a load calculation on the whole house so we know whether the new main system should be sized differently to work with the existing mini split. That way you don’t pay for a tonnage you don’t need, and the two systems stop fighting each other. Call (361) 306-9515 for a free estimate and we will walk the house with you.
If the system is under 10 years old and the failed part is not the compressor or the coil, repair usually makes sense. If it’s over 12 to 15 years old, runs on R-22, or has needed multiple repairs in the last two years, replacement usually wins on total cost. In Grayson, many original builder-grade units are at that point. We will give you the honest math either way, in writing, before you decide.
SEER2 is the efficiency standard for heat pumps sold since 2023, and the number tells you how much cooling you get per watt of electricity. In Grayson’s hot, humid summers, a jump from an old 10 SEER unit to a 16 or 17 SEER2 system means your AC runs less to hold the same indoor temperature, which shows up on the bill. We will translate the rating into estimated dollars for your specific square footage and current system.
It’s included on every full installation, no separate charge. We measure the conditioned square footage, window area, insulation levels, and duct condition, then size the system to that. In Grayson, where many homes have a later-added bonus room or finished basement that never got a proper sizing, skipping the load calculation is exactly how you end up with short-cycling and early compressor failure.
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Brand matters less than correct sizing and a clean installation, but some brands have better parts availability in the Grayson area, and some have stronger Georgia rebates. We will walk you through the real differences and let you pick, with the installer’s honest take on each.
