A properly sized and installed heat pump keeps your home comfortable year-round without the fuel bills that come with a gas furnace. Most our Heat Pump Installation in Houston jobs run between $3,500 and $7,500 depending on the size of your home, the efficiency rating of the unit, and whether your existing ductwork needs work. That’s the honest range, and you’ll get a written price before we ever touch a tool.
Dalton Heating & Air Houston has installed and serviced heat pumps across the Houston area since 2003 as part of the Garrison Partners network. We hold every job to The Garrison Standard: arrive inside the stated window, put the price in writing before any work begins, do the job by the book, leave the site clean, and stand behind the work for a full year. Marco Benitez leads our Houston team, and he’s the one who makes sure that standard gets met on every single job.
If your current heat pump is struggling or you’re ready to make the switch from a furnace-and-AC combo, call (903) 494-7686 for a free estimate. A real person answers, 24 hours a day.
Mini Split Installation
Mini split installation puts a heat pump in individual rooms or zones without needing ductwork, which makes it a practical choice for Houston homes with window units, add-on rooms, garages, or sunrooms. Depending on the number of indoor heads and the capacity of the outdoor unit, you can expect to pay within the $3,500 to $7,500 range for a complete system, with smaller single-zone jobs on the lower end. Dalton Heating & Air Houston handles everything from a single room to a whole-house multi-zone setup, and the price is in writing before the first line set gets run.
Where Ductless Makes Sense
Older Houston homes without central ductwork, converted garages, and room additions are the most common candidates for mini splits. We also see them in homes where one room never cools right despite a perfectly good central system.
What the Install Involves
We mount the indoor unit on an exterior wall, run a small refrigerant line set to the outdoor condenser, and connect the electrical. Most single-zone installs finish in a day, and we leave the site clean enough that you’d never know we were there.
Styles & brands we work with
Heat Pump Maintenance
Heat pump maintenance is a twice-a-year visit that keeps the system efficient and catches small problems before they become expensive repairs, and in Houston’s humidity it matters more than in drier climates. A maintenance visit runs $80 to $200 depending on the depth of the check. Our technicians clean the coils, check refrigerant levels, test the reversing valve, inspect electrical connections, and verify the system is moving heat the right direction for the season.
What Gets Checked
Coil cleanliness is the big one in Houston, because our air is wet and coils foul faster here than almost anywhere else. Dirty coils force the compressor to work harder, which shortens the life of the unit and shows up on your electric bill.
When to Schedule It
Spring and fall, before the heavy heating and cooling seasons, is the right time. If you can’t remember the last time anyone looked at the heat pump, that’s a sign it’s time.
Geothermal Heat Pump Installation
Geothermal heat pump installation uses the ground instead of outside air as the heat source and heat sink, which works exceptionally well in the Houston area because soil temperatures stay steady year-round around 70 degrees. Geothermal installs run at the top of the $3,500 to $7,500 range and often beyond depending on the drilling work required, but the operating costs are dramatically lower than air-source systems. Our team at Dalton Heating & Air Houston assesses your lot, soil conditions, and existing ductwork before any proposal gets written.
Why Geothermal Costs More Up Front
The ground loop requires either horizontal trenches or vertical boreholes, and that excavation or drilling is the biggest cost driver. The tradeoff is a system that can last 25 years or longer on the ground loop side, and monthly bills that run a fraction of an air-source unit.
Is Your Lot a Fit
Horizontal loops need a decent amount of open yard space, while vertical loops work on smaller lots and are common in tighter Houston subdivisions. We’ll tell you which is right for your property before you commit to anything.
Ductless Heat Pump Installation
Ductless heat pump installation is the same technology as a mini split, but the term usually means a system with multiple indoor heads serving several rooms from one outdoor unit. For most Houston homes, a ductless heat pump installation lands in the $3,500 to $7,500 range depending on how many zones you need. Dalton Heating & Air Houston sizes each indoor head to the room it serves so you aren’t paying to cool or heat square footage you don’t use.
Sizing Each Zone
The biggest mistake we see with ductless systems is oversized indoor units that short-cycle and leave rooms humid. In Houston, humidity control is half the battle, so we size each head carefully rather than using a one-size-fits-all calculation.
Multi-Zone vs. Single-Zone
Single-zone ductless systems cost less and work well for one problem room. Multi-zone systems cost more up front but give you independent temperature control in each room, which matters in two-story homes where upstairs and downstairs never seem to agree.
Heat Pump Service
Heat pump service covers the repair and diagnostic work that keeps your existing system running between maintenance visits, and most calls in Houston fall in the $150 to $650 range depending on the part and the labor involved. If your heat pump has stopped heating, is making a noise it didn’t make last week, or is running but not changing the indoor temperature, that’s a service call. Dalton Heating & Air Houston sends a background-checked, uniformed technician with the parts stocked on the truck to get it handled in one trip.
What We Diagnose Most in Houston
Reversing valve failures and capacitor problems are the two biggest heat pump service calls we see in the Houston area. Both can look like a dead system, and both are usually repairable without a full replacement.
The Diagnostic Fee and Guarantee
You’ll know the diagnostic cost before the technician arrives, and any repair price gets written down before work begins. Every repair carries a full-year written guarantee, and if it fails inside that window, we return at no charge.
Heat Pump Replacement
Heat pump replacement is the job when your existing heat pump is beyond economically sensible repair, which typically means a compressor failure on a unit outside its warranty or a system old enough that its efficiency has fallen off a cliff. A full replacement in Houston runs $3,500 to $7,500 depending on the size and efficiency of the new unit. Dalton Heating & Air Houston gives you a written price before we order any equipment, and the new system carries the full manufacturer warranty plus our installation workmanship guarantee.
Repair or Replace
As a rule of thumb, if the repair is going to cost more than 40 percent of the unit’s value and the system is over ten years old, replacement usually makes more sense. We’ll lay out both numbers and let you decide with real figures in front of you.
What Happens to the Old Unit
We remove the old heat pump, handle the refrigerant recovery legally, and dispose of the equipment so you don’t have a rusting hulk sitting by the fence. The site gets left clean, per The Garrison Code.
Brands We Service
We’re factory-trained on Carrier, Trane, Lennox, and Goodman heat pumps, among the nine major residential brands we service across Houston. That means we stock OEM parts for these units and know their common failure points before we even open the panel. A Carrier heat pump from the last decade has specific reversing valve quirks, and a Goodman unit from certain model years has known capacitor issues, and we know both well enough to diagnose them fast.
The brand on the unit matters less than the quality of the install and the quality of the service after the install, and that’s what Dalton Heating & Air Houston is built on. Whether you have Carrier, Trane, Lennox, Goodman, or any other make, we can get it running right.

- No heat or no cooling, or both. A heat pump that won’t move heat in either direction often points to a failed reversing valve or a dead compressor. Don’t keep cycling the thermostat, that can cause further damage.
- Ice building up on the outdoor unit. Some frost is normal in winter, but thick ice that won’t defrost means the defrost cycle has failed or refrigerant is low. Running it like this can destroy the compressor, and that’s a replacement-level repair.
- A sound you can describe but didn’t used to hear. Grinding, rattling, or buzzing from the outdoor unit usually means a motor bearing, a loose fan blade, or a failing contactor. These are fixable, but only if caught before the part breaks loose and takes out something expensive with it.
- Electric bills climbing with no change in usage. A heat pump losing efficiency uses more power to deliver the same comfort. In Houston, where we run heat pumps hard from March through October, a 20 percent bill spike is often the first sign something’s wrong.
- Short cycling or running constantly. A system that kicks on and off every few minutes or runs for hours without reaching set temperature is either oversized, low on refrigerant, or has a thermostat problem. All three are service calls worth making sooner than later.
Our Process, Step by Step
- 1
The call. You call (903) 494-7686 and a real person answers, not a voicemail queue. We book a visit window that works for your schedule, and the technician arrives inside that window, every time.
- 2
The assessment. The technician walks your system, checks the existing equipment, the ductwork where relevant, and the square footage being served. We use a manual load calculation for new installs rather than guessing, because a wrong-sized heat pump is a lifetime of regret.
- 3
The written price. Before any work begins, you get a written price for the entire job. No verbal estimates that drift, no add-ons at the door. The number you see is the number you pay.
- 4
The work. The install or repair gets done by the book, per The Garrison Code. That means manufacturer specifications, proper refrigerant handling, and a clean site when we’re done. No shortcuts, no half-finished work left for the next guy.
- 5
The stand-behind. Every repair carries a full-year written guarantee, and every install carries our workmanship guarantee on top of the manufacturer warranty. If something isn’t right, we come back and make it right, no charge.
How Much Does Heat Pump Installation Cost in Houston?
A typical heat pump installation in Houston runs $3,500 to $7,500 depending on three factors: the size of the home, the efficiency rating of the unit, and whether the existing ductwork needs modification. Learn more about how much Heat Pump Installation costs. A simple replacement of a 2.5-ton unit in a modest single-story home lands near the bottom of that range, while a high-efficiency 5-ton system for a larger two-story home with ductwork fixes lands near the top.
What affects the price the most is the efficiency rating, because a higher SEER2 rating costs more up front but returns savings every month on the electric bill. In Houston, where cooling dominates the bill from April through October, a jump from a 14 SEER2 to a 18 SEER2 unit can knock a meaningful percentage off the annual power cost. The second-biggest factor is ductwork: if your existing ducts are undersized or leaky, fixing them before installing a new heat pump is the difference between a system that hums and one that fights itself.
The way to avoid overpaying is simple: get the price in writing before work starts, and make sure it includes removal of the old unit, refrigerant recovery, and any needed electrical work. A free estimate from Dalton Heating & Air Houston includes all of that, itemized, so you know exactly what you’re paying for before you commit.

Frequently Asked Questions About Heat Pump Installation in Houston
A heat pump installation is the process of removing your old heating and cooling system and installing a new unit that moves heat rather than generating it, which means it both cools in summer and heats in winter. In Houston, a heat pump is often a smarter choice than a separate furnace and air conditioner because it handles both jobs in one unit. The installation includes the outdoor condenser, the indoor air handler, refrigerant line connections, and electrical work.
Most heat pump installations in Houston take one full day, with some larger jobs or those requiring ductwork modifications taking a second day. We’ll tell you upfront what the timeline looks like based on your specific situation. The site gets left clean, and we walk you through how to operate the new thermostat before we leave.
Expect to pay between $3,500 and $7,500 for a complete heat pump installation in Houston, with the final number depending on the size of your home, the efficiency rating of the unit, and the condition of your existing ductwork. We give you a written price before any work begins, so you’ll never be surprised by a number at the end. Call (903) 494-7686 for a free estimate with a written price.
