We know Lewisville’s streets, subdivisions, and housing stock because our crews are out here every week. From the older 1980s ramblers off Valley Ridge Boulevard to the newer builds around Garden Ridge and Castle Hills, we’ve seen which systems hold up, which ones fail early, and what a proper installation actually requires in this climate. Our Heat Pump Installation team handles the full job: load calculation, equipment selection, duct assessment, installation, startup verification, and the paperwork on any rebates you qualify for.
We serve Heat Pump Installation in Lewisville with local crews, not subcontractors from the other side of the metroplex. When you call, you reach a person. When we arrive, you already know the technician’s name and what they look like. No mystery, no waiting games.
Why Dalton Heating & Air Is Lewisville’s Preferred Heat Pump Installation Company
Dalton Heating & Air is a Garrison Partners company, operating under The Garrison Standard since 2003. That means every job in Lewisville carries the same non-negotiable terms: a written price before any work starts, a written guarantee on every repair, and a free return visit if the repair fails within the guarantee period. Marco Benitez runs our local operation, and he holds every technician to The Garrison Code: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.
Our technicians are background-checked and uniformed, so you know who is coming before they ring the doorbell. They are factory-trained to service nine major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Lewisville because we see a real mix of equipment out here. Some homes have original builder-grade units from the early 2000s still limping along. Others have a newer system that was installed wrong. Our crews diagnose both correctly because they have seen both hundreds of times.
We stock common replacement parts locally for Lewisville customers, which cuts turnaround time on repairs and replacements. When a heat pump compressor contactor fails on a Friday afternoon in The Colony or Flower Mound, we are not waiting on a parts shipment from Dallas. We pull it from local stock and fix it same-day. That is the difference between trusting a crew and gambling on a stranger.
Ductless Heat Pump Installation in Lewisville
Ductless Heat Pump Installation is a smart fit for Lewisville homes with additions, converted garages, sunrooms, or any space where running ductwork is impractical or would tear up finished walls. It is also the right answer for older Lewisville houses that never had central ducting, or for homeowners who want zone control room by room instead of heating and cooling the whole house to one thermostat setting. In Lewisville, a single-zone ductless installation typically falls in the $3,500 to $7,500 range, with multi-zone systems landing at the upper end.
When Ductless Makes Sense
A ductless system shines when a room sits too far from the main unit, or when a load calculation shows the existing ductwork cannot move enough airflow to condition a new space. We see this regularly in Lewisville’s older 1980s and 1990s subdivisions, where original ducts were sized for a smaller system and have since sagged, separated, or leaked so badly that adding a room means adding a mini split rather than fighting the existing duct design.
What the Installation Involves
We mount the indoor air handler on an exterior wall, run a small refrigerant line set to the outdoor condenser, and set up the controls. The line set passes through a hole about the size of a quarter, so finished walls stay intact. Our crew levels the outdoor unit on a pad or wall bracket, verifies the refrigerant charge by subcooling at startup, and walks you through the controller before we leave. Every ductless job gets the same written guarantee as a central system: a full year, in writing, with a free return visit if anything fails.
Heat Pump Service in Lewisville
Heat Pump Service in Lewisville means diagnosing and repairing the system you already have, not pushing you into a replacement you do not need. Most heat pump repairs in Lewisville run $150 to $650 depending on the failed part, and a seasonal tune-up runs $80 to $200. We give you a straight answer on whether a repair is worth making, and we put that answer in writing before we touch a single component.
What a Service Call Covers
A service call starts with a system-wide diagnostic, not a quick glance at the thermostat. Our technician checks the reversing valve operation, refrigerant charge, defrost board, capacitor health, and airflow through the coil. On a heat pump, a weak capacitor or a slightly low charge will present as reduced heating output in winter and reduced cooling in summer. We find it, quote the fix, and get your written approval before doing the work.
Seasonal Tune-Ups for Heat Pumps
A heat pump in Lewisville runs year-round, which means it accumulates wear faster than a furnace or air conditioner that sits idle for half the year. A seasonal tune-up at $80 to $200 catches failing parts before they cascade, checks the refrigerant level, and verifies that the defrost cycle is working before the first freeze. Homeowners who tune their heat pump twice a year typically get longer equipment life and fewer emergency calls.
Trusted Brands We Service in Lewisville
We install and service major residential brands including Goodman, Rheem, York, and Daikin, plus Carrier, Trane, Lennox, Bryant, and American Standard. Our factory training covers all nine, which means you get a technician who actually knows your system, not someone reading the manual to figure out what that blinking fault code means. We keep common parts for these brands in local stock, so a replacement board or fan motor for a Goodman or Rheem unit does not leave you waiting for a shipment. If your heat pump is eight years old or has needed two repairs in the past year, we will also tell you straight whether the repair makes sense or whether you are better off putting that money toward a new system.
Common Heat Pump Installation Problems We See in Lewisville Homes
- Oversized equipment that short-cycles. Lewisville sits on the Blackland Prairie where summer design temperatures push 100°F while winter mornings still dip below freezing, so a heat pump here must be sized and charged to handle both extremes. When a unit is oversized by rule-of-thumb tonnage rather than a Manual J load calculation, it short-cycles in spring and fall, leaving the evaporator coil wet and the house clammy. A proper load calculation prevents this and typically saves money on the equipment itself.
- Refrigerant charge never verified after installation. A heat pump charged by “beer can cold” at the condenser coil will underheat at 30°F and drive up auxiliary heat strip runtime on winter bills. We check charge by subcooling for TXV systems and by superheat for fixed-orifice systems, which is the only way to know the charge is right for both heating and cooling modes. This is a common miss on installs done by crews rushing to the next job.
- Static pressure that kills efficiency before the system ever runs. Lewisville’s mix of older 1980s-90s subdivisions and new construction means ductwork often cannot move the cfm a new inverter heat pump needs. When static pressure runs high, the system never delivers the SEER2 rating on the label. We measure it during startup instead of assuming the ducts are fine.
- Undersized wiring or breaker on the air handler circuit. In older Lewisville homes, we regularly find 14-gauge wire and a 15-amp breaker where a new variable-speed air handler needs 12-gauge and a 20-amp circuit. We check this during the load calculation, not after the breaker trips on the first cold morning. It is a small detail that separates a clean install from a callback.
Pricing for Heat Pump Installation in Lewisville, TX
Here are the numbers we actually work from in Lewisville, as of March 2026. A heat pump replacement runs $3,500 to $7,500 depending on the equipment tier, the complexity of the ductwork, and whether you go with a single-stage or inverter-driven unit. Repairs on an existing heat pump run $150 to $650, and a seasonal tune-up runs $80 to $200. We do not quote low over the phone and pad the invoice at your door. The price is in writing before any work starts, and it does not change unless you approve additional scope in advance.
| Service | Typical Range in Lewisville |
|---|---|
| AC Repair (heat pump diagnostics and repair) | $150 – $650 |
| AC Installation (heat pump replacement) | $3,500 – $7,500 |
| Tune-Up (heat pump seasonal maintenance) | $80 – $200 |
What moves the price on a heat pump installation is mostly the equipment tier and the ductwork condition. A basic 14 SEER2 single-stage Goodman or Rheem runs at the lower end. A mid-tier 16-17 SEER2 two-stage unit from York or Daikin lands in the middle. A high-end inverter system with a variable-speed air handler pushes toward the upper end. If your ductwork needs sealing, modifications, or full replacement, that is priced separately and shown in writing before we start. Call (361) 306-9515 for a free estimate. We come out, measure, run the load calculation, and hand you a written price. No obligation.
We replaced a 16-year-old single-stage heat pump in the North Mill neighborhood off Edmonds Lane with a 3-ton Carrier inverter unit after a load calculation showed the old system was oversized and the homeowner was paying for capacity they never used. During startup we checked static pressure, verified refrigerant charge by subcooling, and found a weak capacitor that had been masking a hard-starting compressor for two seasons. The new system cut their August cooling runtime roughly in half and held setpoint on a 28°F January morning without strips kicking in.

FAQs About Heat Pump Installation in Lewisville
Repair the heat pump if it is under 10 years old, the failed part costs under $650 to replace, and the system holds setpoint without running the auxiliary strips all winter. Replace it if the compressor has failed, the coil is leaking refrigerant, or the unit is past 12 years and repairs are stacking up. In Lewisville, where summer design temperatures near 100°F and winter mornings hit freezing, a system that struggles in one season usually fails the other too. We give you a straight repair-versus-replace recommendation in writing before you spend a dollar. Call (361) 306-9515 and we will come out and diagnose it honestly.
A load calculation matters in Lewisville because the local climate demands both high cooling capacity in August and real heating capacity in January. Lewisville sits on the Blackland Prairie, where summer design temps push 100°F while winter mornings still dip below freezing, so a heat pump here must be sized for both extremes, not a mild-climate spec. An oversized unit short-cycles through the humid spring and fall, leaving the house clammy and the coil wet. An undersized unit runs the auxiliary heat strips all winter and sends your electric bill through the roof. The only way to know is a Manual J load calculation, which we include with every heat pump installation estimate.
SEER2 is the updated efficiency rating that measures cooling output per watt of electricity, tested under more realistic conditions than the old SEER rating. In dollars, going from a 14 SEER2 heat pump to an 18 SEER2 inverter unit typically cuts cooling-season electric usage by 20 to 30 percent, which for a Lewisville home paying $180 to $250 a month for summer cooling saves $400 to $750 a season. The catch is that the system only delivers the rated SEER2 if the ductwork and static pressure are right. We measure both at startup, because a high-efficiency unit on leaky or undersized ducts never hits its rated number. Call (361) 306-9515 and we will show you the math for your specific house.
Yes. We install ductless mini split heat pumps in Lewisville for additions, converted garages, sunrooms, and any space where ductwork is impractical. A single-zone ductless installation in Lewisville typically runs $3,500 to $7,500, with multi-zone systems landing at the upper end. Ductless mini splits also let you heat and cool room by room, which matters in older Lewisville homes where some rooms get full afternoon sun while others stay shaded. Call (361) 306-9515 for a free estimate on a ductless system.
Service a heat pump in Lewisville twice a year, once before cooling season and once before heating season. A heat pump runs year-round in this climate, so it accumulates wear faster than a furnace or air conditioner that sits idle for half the year. A seasonal tune-up runs $80 to $200 and catches failing capacitors, low refrigerant, dirty coils, and defrost board issues before they cause a breakdown. At minimum, do it once a year in the fall before heating demand starts. Call (361) 306-9515 to schedule a tune-up, and we will send a written report of what we found and what it means.
If your heat pump is struggling in Lewisville, do not wait for a 100-degree afternoon or a freezing morning to find out it is done. Call (361) 306-9515 now. We answer live, schedule fast, and put the price in writing before any work begins. The estimate is free, and the decision is yours.
