Dalton Heating & Air works in Justin weekly. Our techs know the difference between a tight, new-build home near Harriet Creek and an older rural property off Sam Reynolds Road that still runs on well water. That difference changes what heat pump gets installed, how the ductwork gets checked, and what the electric bill does afterward. You get our written price before any work begins, and a full-year written guarantee on the install.
Why Dalton Heating & Air Is Justin’s Preferred Heat Pump Installation Company
Justin sits in a strange in-between: fast new subdivisions going up along FM 156 and FM 407, while ranchette-style properties with acreage and older mechanical rooms still dot the area from Justin Road west toward the Wise County line. One-size-fits-all heat pump sizing fails in both directions here. A system sized for a tight new home underperforms in an older structure with real air leakage, and equipment sized by square footage alone short-cycles in homes with spray-foam insulation. Our crews run a Manual J load calculation on every install, which means we measure the actual building, not the builder’s guess.
Marco Benitez, who leads Dalton Heating & Air, holds every tech to The Garrison Code: 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. That’s not marketing language. It’s the operating standard a Garrison Partners company has followed since 2003. If the install doesn’t hold up in that first year, we return at no charge under the 365-Day Done Right Promise.
When you call, a live person answers, 24/7. You’ll know who is coming before the truck pulls up, because every tech is background-checked and uniformed. Dispatch for Justin is coordinated from our Dallas-Fort Worth office, but the crews serving Justin are local to the northern Denton County area.
Geothermal Heat Pump Installation in Justin
Geothermal Heat Pump Installation in Justin is a specialized job that makes real sense on the rural-acreage properties west of town, where there’s room for the ground loop field. Instead of pulling heat from outdoor air, a geothermal system runs water or refrigerant through buried loops and pulls stable ground temperature, which runs around 60-plus degrees in north Texas year-round. That stability cuts electric use substantially compared to an air-source heat pump, especially in July and August when outdoor air temps push into the high 90s and beyond.
For a Justin homeowner with enough land for a horizontal loop field, a geothermal install runs at the upper end of our $3,500 – $7,500 equipment range, with the loop field and excavation quoted separately after a site survey. The math matters: the equipment itself is not wildly more expensive; the ground work is. We’ll give you a written, fixed price after we walk the property and check soil conditions.
When a Ground Loop Makes Sense
The best geothermal candidates in Justin are homes with at least a quarter to half acre of open ground, not the new-construction lots packed into master-planned subdivisions. If you’re on acreage off Sam Reynolds or down near the Denton Creek bottom, you likely have the space. If you’re on a 55-foot lot in a new neighborhood off FM 156, you don’t, and a variable-speed air-source heat pump is the better call.
Open Loop vs. Closed Loop
Rural Justin properties on private wells sometimes ask about an open-loop geothermal setup, which uses well water as the heat-exchange fluid. In Denton County, water rights and well capacity make that a site-by-site decision, and most systems we install here are closed-loop. Closed-loop means the fluid never leaves the buried piping, so there’s no well draw and no discharge permit to chase.
Ductless Heat Pump Installation in Justin
Ductless Heat Pump Installation in Justin is the fastest answer for a room that never holds temperature, whether that’s a converted garage, a sunroom, or an upstairs bonus room over a poorly designed duct run. A ductless mini split puts a small outdoor condenser on a pad or wall bracket and connects to one or more slim indoor heads by a refrigerant line set, so no ductwork is added. For Justin homes where the existing ductwork is undersized or leaky, a ductless system sidesteps the problem entirely.
A single-zone ductless heat pump install in Justin typically runs inside the $3,500 – $7,500 range depending on the number of indoor heads and the length of the line set. That’s real money, but it is often less than tearing out and replacing ductwork in an existing home. Every install gets the same written price before work begins and the same full-year guarantee.
Multi-Zone vs. Single-Zone
A single-zone unit handles one room. A multi-zone outdoor condenser can run two, three, or four indoor heads, which works well for Justin ranchers and two-stories where one problem room becomes two problem rooms in different seasons. We won’t sell you more zones than the electrical panel and the condenser’s capacity can actually support; our techs verify both before recommending a configuration.
What a Ductless Installed Wrong Looks Like
On a two-story home off FM 156 near the Harriet Creek area, our tech found a builder-grade 3-ton heat pump whose condenser coil was caked and whose refrigerant charge was low after a bad install, leaving the upstairs short on cooling all summer. Rather than quote a replacement, we ran a Manual J load calculation, corrected the static pressure on the undersized return, recharged the system, and set the thermostat calibration. The homeowner got real comfort for a fraction of new-equipment cost. When the family did later replace a second unit, we installed a Carrier variable-speed heat pump and walked them through what the SEER2 rating meant on their actual electric bill.
Trusted Brands We Service in Justin
Our techs are factory-trained on the heat pump equipment we install most often in Justin: Goodman, Rheem, York, and Daikin. That matters because parts availability and warranty processing move faster when the installing crew actually knows the brand’s engineering. We stock common capacitors, contactors, boards, and blower motors locally for Justin customers, so a repair doesn’t stall waiting on a part shipped from out of state. When a specific Daikin or Rheem part isn’t on the truck, our DFW parts network usually has it same day. Read more about our broader heat pump work on our Heat Pump Installation service page.
Common Heat Pump Installation Problems We See in Justin Homes
- Tonnage mismatched to the home. Builder-grade heat pumps go in without a load calculation in Justin’s fast-growing new subdivisions, leaving a 2-ton unit on a 3-ton load. The blower motor runs constantly, the house never reaches set temperature on a hot afternoon, and the compressor fails early.
- Coil fouling on rural properties. Homes off the paved corridor near open pasture see condenser coils and evaporator coils load with dust and pollen faster than in dense metro neighborhoods. That raises head pressure, cuts capacity, and shortens compressor life if not cleaned.
- Undersized or badly routed ductwork. Tight new construction and older ranch-style homes both show this. High static pressure from undersized returns masks a weak capacitor or a low refrigerant charge until the compressor dies in peak summer.
- Improper refrigerant charge from the original install. We see factory charges that were never adjusted for line-set length on new-construction systems around Justin. That low charge shortens cooling capacity and drives up the electric bill in the first season the home is occupied.
Pricing for Heat Pump Installation in Justin, TX

FAQs About Heat Pump Installation in Justin
If the repair is a capacitor, a contactor, or a refrigerant charge correction on a system under 12 years old, repair first. The repair cost in Justin runs $150 – $650, and we guarantee it in writing for a full year. Replace when the compressor has failed, the system is over 12 years old and leaking refrigerant, or a load calculation shows the unit was the wrong size from the start. Call (361) 306-9515 and we’ll give you an honest read, not a sales pitch.
Because Justin’s housing stock is split between tight new construction and older rural properties, so square footage alone gives you the wrong answer. A Manual J load calculation measures insulation, window area, air leakage, and orientation to size the heat pump correctly. Skip it and you’re buying a system sized by guesswork. Every install we do includes the calculation as standard.
SEER2 is the updated federal efficiency test that measures how much cooling a heat pump delivers per watt of electricity under real-world conditions. A higher SEER2 number means a lower electric bill at the same thermostat setting. Our techs explain the difference between, say, a 14.3 SEER2 and a 17 SEER2 unit on your actual Justin home before you sign anything.
Yes. We install single-zone and multi-zone ductless heat pumps throughout Justin, from new subdivisions to acreage properties. A ductless system works well for problem rooms, converted garages, and add-ons where running ductwork isn’t practical. The install runs $3,500 – $7,500 depending on the number of indoor heads. Estimates are free.
For rural Justin properties with enough open ground for a loop field, yes, geothermal delivers the lowest operating cost of any heat pump type. For homes on small subdivision lots, the excavation and loop work usually erase the efficiency savings. Call (361) 306-9515 for a site walk and a written quote, and we’ll tell you which direction the math actually favors.
