Why Dalton Heating & Air Is Keller’s Preferred Heat Pump Installation Company
Keller homeowners call us after they’ve been burned. Not metaphorically, but actually: they hired a crew that showed up three hours late, quoted one number, then slid a different invoice across the kitchen counter. That doesn’t happen with us. Dalton Heating & Air is a Garrison Partners company held to The Garrison Code since 2003: arrive inside the window, price in writing before starting, do the job by the book, leave the site clean, stand behind the work for a full year. Marco Benitez runs our crews by that code on every single job, no exceptions.
Our technicians are background-checked, uniformed, and factory-trained on nine major residential brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. When we pull up to a house off Keller Parkway or along Rufe Snow Drive, we already know the neighborhood, the housing stock, and the likely duct configuration. That’s not a marketing line. It’s what happens when a crew works the same city for years and actually pays attention to what’s inside the attics.
We answer the phone with a live person, not a voicemail tree. Every repair carries a written guarantee. If the work fails within that year, we come back at no charge. That’s the 365-Day Done Right Promise, and it applies to every heat pump we touch in Keller.
Heat Pump Service in Keller
Heat Pump Service in Keller covers the full inspection, diagnosis, and repair of the outdoor condenser, indoor air handler, and the refrigerant lines connecting them. A Keller homeowner needs this when the system runs but won’t reach setpoint, when the outdoor unit ices over in winter, when the compressor short-cycles, or when the electric bill spikes for no obvious reason. Diagnostics run $150 to $650 depending on what we find. The service call price is written down before we touch anything, and the repair is guaranteed in writing for a full year.
Diagnostic Calls and Defrost Issues
Keller heat pumps run in a peculiar spot: hot enough in August to push the compressor hard, cold enough in January to trigger defrost cycles regularly. When a defrost board fails or a sensor reads wrong, the coil ices over and the system struggles to heat. We see it constantly in Keller’s larger two-stories, especially units matched to older air handlers that can’t handle the refrigerant charge.
Refrigerant and Airflow Corrections
Low refrigerant charge, meaning the cooling fluid has leaked or was never set right, is the single most common service finding we make in Keller. We also measure static pressure in the ductwork. On a 1990s home in Hidden Lakes, we found 0.9 inches of water column, nearly double what the blower is rated for. Correcting that airflow problem did more for comfort than any compressor swap would have.
Heat Pump Replacement in Keller
Heat Pump Replacement in Keller means removing the old outdoor unit and evaporator coil, evaluating the existing ductwork and line set, then installing a new system sized to the actual load of the house, not a rule-of-thumb guess. A Keller homeowner needs replacement when the compressor has failed, the unit uses R-22 refrigerant, or repair costs push past half the price of a new system. Full 3-ton replacements run $3,500 to $7,500. We write the price before we order equipment, and the install date is set before we start.
Sizing to the House, Not the Square Foot
The worst mistake we see in Keller is a replacement heat pump installed on tonnage alone. A 3,200-square-foot two-story with west-facing glass near the Keller Pointe and a 2,400-square-foot ranch off Johnson Road are different houses. A Manual J load calculation, meaning the heat gain and loss measurement that accounts for windows, insulation, ceiling height, and orientation, tells us what the house actually needs. Skip that step and you get short-cycling, humidity problems, and higher bills.
Replacing the Coil and Air Handler Together
When we replace a heat pump in Keller, we replace the indoor coil at the same time. Matching a new outdoor unit to an older air handler or evaporator coil is how you get defrost-cycle failures come January. The refrigerant charge has to be exact, and the airflow has to support the new compressor. If it doesn’t, the system locks out on the coldest night of the year. That’s not a phone call we want a Keller homeowner making.
Trusted Brands We Service in Keller
We install and service heat pumps from Goodman, Rheem, York, and Daikin, along with five other major brands, and we keep common parts for those systems stocked locally for Keller customers. That means a failed capacitor or a bad defrost sensor doesn’t turn into a two-day wait while someone ships a part from a distributor across the metro. When a Keller homeowner on Bear Creek Parkway needs a heat pump back online in January, we pull the part, make the repair, and put the guarantee in writing. Same standard whether it’s a Goodman single-stage or a Daikin inverter unit.
Common Heat Pump Installation Problems We See in Keller Homes
- Oversized units on rule-of-thumb tonnage. Many Keller homes, especially the larger two-stories built in the 1990s and 2000s, have replacement heat pumps that were sized by guesswork. A 5-ton unit on ductwork rated for 3.5 tons moves less air, runs short cycles, and spikes the electric bill.
- Defrost failures from mismatched equipment. When a new outdoor unit is paired with an older coil or air handler, the defrost cycle can’t pull enough heat. We see this in Keller every winter, and the fix almost always involves replacing the indoor equipment, not the outdoor unit.
- Compressors that fail from neglected capacitors. A weak capacitor left undiagnosed through a Keller summer forces the compressor to work against itself. By the time January arrives, the unit locks out. The repair is cheap if caught early; it’s a replacement if ignored.
- Duct leaks and high static pressure. Keller homes built before 2005 often have supply runs that are undersized or leaking in the attic. We measure static pressure on every install because a heat pump is only as good as the ducts it pushes air through.
Pricing for Heat Pump Installation in Keller, TX
| Service | Typical Keller Price Range |
|---|---|
| Heat Pump Replacement (3-ton, full system) | $3,500 – $7,500 |
| Heat Pump Service / Diagnostic | $150 – $650 |
| Heat Pump Tune-Up | $80 – $200 |
What moves the replacement number is equipment efficiency, brand, and whether the ductwork needs correction. A single-stage Goodman going into a house with clean ducts sits at the low end. A variable-speed Daikin with sealed supply runs and a new line set sits higher. Either way, the price is fixed before we order anything. Estimates are free. Call (361) 306-9515 and we’ll give you a written number, not a ballpark.

FAQs About Heat Pump Installation in Keller
Yes, but only if it’s sized and configured for Keller’s specific climate, not a generic DFW install. A modern cold-climate heat pump holds capacity down into the single digits and runs defrost cycles to keep the outdoor coil clear. What matters in Keller is that the system is sized on the cooling load first, because August pushes near 100°F, while still holding enough heating capacity for January nights in the teens. A load calculation tells us exactly where that balance point falls for your house. Call (361) 306-9515 and we’ll run the numbers specific to your home, not a county average.
A load calculation, meaning the Manual J heat gain and loss measurement, changes the tonnage, the airflow setup, and the duct corrections we make before the new system goes in. In Keller, where summer design temperatures approach 100°F and winter lows dip into the teens, that calculation determines whether a 3-ton or 4-ton unit is correct, and whether the existing ductwork can move the air that unit produces. Skip it, and you get a heat pump that short-cycles, leaves rooms hot, and drives humidity into the house. We run it on every replacement we install in Keller. Call (361) 306-9515 for a written estimate that includes the load calculation, not just a price.
For most Keller homes, a 15-to-17 SEER2 heat pump balances upfront cost against electric-bill savings. Keller’s hot, humid summers mean the cooling side runs hard for five or six months, so jumping from a 14 SEER2 to a 16 or 17 SEER2 unit usually pays back within the equipment’s lifespan. Higher-efficiency variable-speed units run $5,500 to $7,500 here, and they’re worth it if your current system is over 12 years old or if your summer electric bill runs north of $350. Call (361) 306-9515 and we’ll show you the payback math for your actual house, not a brochure.
If the compressor has failed, the unit uses R-22 refrigerant, or the repair quote is more than half the cost of a new system, replacement is the honest call. A dead compressor on a 12-year-old heat pump is almost never worth rebuilding. A failed capacitor or a refrigerant leak on a 6-year-old unit is usually a repair. In Keller, we also factor in the house itself: if the system was oversized or the ducts are leaking badly, that pushes toward replacement with the ductwork corrections done at the same time. Call (361) 306-9515 and a technician will give you the repair-versus-replace answer in writing, with prices for both.
The most common heat pump failure we see in Keller is a compressor that locked out in winter because a weak capacitor or low refrigerant charge went undiagnosed through the summer cooling season. The system limped through August, worked harder than it should have, and finally failed on a cold January morning. It’s preventable: a $80 to $200 tune-up catches both issues before they become a $3,500 replacement. Call (361) 306-9515 to schedule a tune-up, and we’ll put what we find in writing, with no pressure to buy anything.
