AfterHeat Pump Installation Done Right, Nationwide
A heat pump does two jobs with one machine: it cools your home in summer and heats it in winter. That only pays off when the unit is sized correctly, the refrigerant lines are clean and tight, and the airflow is set up properly. Heat pump installation is where most of that is won or lost. Since 2003, Coldharbour Heating & Air has installed heat pumps for homeowners across the United States, and every installation carries the 365-Day Done Right Promise: a written guarantee that if the work fails within a full year, we come back and fix it at no charge. A live person answers our phones 24 hours a day, seven days a week. Call (817) 402-2972 and you’ll get a real scheduling conversation, not a voicemail. Most heat pump installations run between $4,500 and $12,000 depending on system type and home layout, and you’ll have a written price before any work begins.
Key Takeaways
- Heat pump installation typically costs $4,500 to $12,000 depending on system type, size, and whether ductwork needs changes.
- Every installation comes with the 365-Day Done Right Promise in writing, not just a verbal assurance.
- A live person answers the phone 24/7, including nights, weekends, and holidays.
- We install and service nine major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
- You get a written price before work starts, and that number does not change at the door.
Mini Split Installation
Mini Split Installation is the right answer for homes with no ductwork, additions that the main system can’t reach, or rooms that never seem to match the rest of the house. A mini split is a heat pump with an outdoor unit connected to one or more wall-mounted indoor heads by a small refrigerant line set. Coldharbour Heating & Air mounts each head where it will actually move air through the room, not just where the wall is convenient. A single-zone mini split usually runs $3,500 to $6,500 installed, and multi-zone systems cost more depending on the number of heads. For a full breakdown of that equipment, see our ductless mini split installation page.
Choosing the number of zones
One zone per room gives the most control, but it isn’t always needed. Two connected rooms with an open doorway can often share one head. We walk the space with you, measure it, and explain what each layout costs before you commit.
Line set and condensate routing
The line set is the part homeowners never see and the part that causes the most callbacks when it’s done badly. We flare, pressure test, and insulate every connection, and we route condensate so it drains away from the foundation instead of pooling under the unit.
Heat Pump Maintenance
Heat Pump Maintenance is the scheduled upkeep that keeps a new installation performing the way it did on day one. A heat pump runs year-round, so it wears faster than an air conditioner that sits idle all winter. That makes yearly service more important, not less. Coldharbour Heating & Air checks refrigerant charge, coil condition, defrost operation, and electrical connections, then hands you a written record of what we found. A maintenance visit typically costs $90 to $220, and it’s the cheapest way to protect a system that cost thousands to install.
Defrost cycle checks
In cold weather, a heat pump’s outdoor coil collects frost and periodically melts it off. When the defrost board or sensor fails, ice builds until airflow stops. We test the full defrost sequence before winter, so you aren’t finding out during the first freeze.
Coil cleaning and airflow
Dirty coils make a heat pump work harder to move the same amount of heat. We clean the outdoor coil, check the indoor blower, and confirm the filter size is right for the system.
Geothermal Heat Pump Installation
Geothermal Heat Pump Installation uses the steady temperature of the ground, usually 50 to 60 degrees a few feet down, as the heat source and heat sink instead of outdoor air. That makes it the most efficient type of heat pump, and also the most involved to install. A buried loop of pipe, either horizontal trenches or vertical bores, carries fluid between the earth and the indoor unit. Costs are higher than air-source systems, often $15,000 to $35,000 or more, and the loop field is the biggest variable. Coldharbour Heating & Air evaluates your lot, soil, and available space before recommending geothermal, and we’ll tell you plainly when an air-source unit is the better value.
Loop field design
Loop length is calculated from your home’s heating and cooling load, not guessed. An undersized loop forces the unit to work against warming or cooling ground, which cuts efficiency and shortens equipment life.
Indoor unit and ductwork
The indoor unit connects to your existing ducts if they are in good shape. We check duct size and leakage first, because a great geothermal system paired with leaky ducts wastes the investment.
Ductless Heat Pump Installation
Ductless Heat Pump Installation covers homes where running new ducts isn’t practical or worth the expense: older houses with plaster walls, sunrooms, finished basements, garage conversions, and accessory units. The system pulls heat out of outdoor air even in cold weather, and modern cold-climate models keep working well below freezing. Coldharbour Heating & Air sizes ductless systems to the actual room load, since an oversized unit short-cycles and never removes humidity properly. Typical installed cost is $3,500 to $9,000 depending on the number of zones. Ductless heat pumps also pair well with a central furnace installation for homes that want a backup heat source.
Wall mounting and placement
Head placement affects comfort more than people expect. Mounted too low, a head blows directly on a sofa. Mounted behind a door swing, it chokes airflow. We mark the spot with you before we drill.
Electrical and disconnect work
Every outdoor unit needs a properly sized circuit and a weatherproof disconnect. We check your panel capacity first and tell you in writing if an upgrade is needed.
Heat Pump Service
Heat Pump Service covers diagnostics, adjustments, and repairs after your system is running. You need it when the unit blows cool air in heating mode, runs constantly without reaching the setpoint, makes new noises, or leaves ice on the outdoor coil that doesn’t clear. Coldharbour Heating & Air sends background-checked, uniformed technicians who arrive in the window we promised, test the system with gauges and meters, and give you a written price before work begins. Service visits typically run $150 to $650 for common repairs. For general heating problems, our heating repair page explains what we fix and how.
Reversing valve problems
The reversing valve switches the system between heating and cooling. When it sticks, you get the wrong kind of air for the season. We test it electrically and by pressure before calling it bad.
Refrigerant and electrical faults
Low charge, failed capacitors, and worn contactors account for most service calls. We find the actual cause instead of replacing parts in the hope one of them fixes it.
Heat Pump Replacement
Heat Pump Replacement is the right call when the system is past its useful life, has a failed compressor, or costs more to keep running than a new one would. Most heat pumps last 12 to 15 years with regular maintenance. If yours is older than that and needs a major repair, replacement usually makes more financial sense. Coldharbour Heating & Air gives you a straight written comparison of repair cost versus replacement cost so you can decide with real numbers. Replacement of a standard air-source unit runs $4,500 to $11,000 including removal and disposal of the old equipment.
Matching indoor and outdoor units
A new outdoor unit paired with an old, mismatched indoor coil often fails to reach its rated efficiency. We check compatibility and replace the coil when the match calls for it.
Old refrigerant and equipment disposal
We recover old refrigerant according to federal rules and haul away the old unit. That removal is part of the written price, not a surprise charge on the invoice.
Brands We Install
Our technicians install and service all major residential HVAC brands. Carrier and Bryant share a platform, and we stock matching parts for both. Trane and American Standard are built the same way, so one training covers both. Lennox systems use proprietary communicating controls that many generalist installers struggle to commission, and our team knows how to set them up correctly the first time. We also install Daikin, Goodman, Rheem, and York. The crew that arrives will know the equipment in your home, not just HVAC in general.
Signs You Should Talk to an Installer
- Your current system is 12 years old or more. Efficiency drops with age, and repair bills climb. A heat pump installed now can cut heating and cooling costs noticeably compared with an aging system.
- Your heating bills keep rising. If you use electric resistance heat, oil, or propane, a heat pump often moves the same heat for far less energy.
- Some rooms are never comfortable. Hot or cold spots usually point to duct problems or an undersized system. A ductless zone can fix a stubborn room without touching the rest of the house.
- The system has a major failure. A dead compressor or leaking coil on an older unit is the moment to price replacement instead of another repair.
- You are adding living space. Extending existing ducts to an addition often leaves it under-served. A mini split sized for the new room is usually cleaner and cheaper.
Our Process, Step by Step
- 1
You call and a live person answers. We’ll ask about your home, your current system, and what you want to fix. You’ll get a firm visit window before the call ends.
- 2
We measure and size the system. A background-checked, uniformed technician measures the home, checks insulation, windows, and ductwork, and calculates the real heating and cooling load. We don’t size by square footage alone.
- 3
You get options in plain English. We explain the choices that fit your home, with the tradeoffs in price, efficiency, and noise, so you can pick without pressure.
- 4
You get a written price before we turn a wrench. The estimate includes equipment, labor, electrical, permits, and disposal. That number is fixed. If we find something unexpected, we stop, explain, and give you a new written price first.
- 5
We install, test, and hand you the guarantee. We pressure test and evacuate the lines, charge the system to spec, measure airflow and temperature split, and walk you through the controls. Then you receive the 365-Day Done Right Promise in writing before we leave.
How Much Does Heat Pump Installation Cost?
A standard air-source heat pump replacement usually runs $4,500 to $11,000 installed. A single-zone ductless mini split is typically $3,500 to $6,500, and multi-zone systems climb from there. Geothermal installations start around $15,000 and can reach $35,000 or more because of the loop field. The final number depends on the size of your home, the equipment you choose, and whether ducts, electrical, or a pad need work.
Several things move the price. Higher-efficiency and variable-speed units cost more up front but use less energy every month. Ductwork in poor condition adds repair cost. Tight attic or crawl space access adds labor. The best way to avoid overpaying is to work with a company that puts the price in writing before the work starts and guarantees the job in writing after it’s done. That’s what we do on every installation, and the estimate is free. Call (817) 402-2972 and we’ll schedule a visit, size the system, and give you a fixed price before any work begins.

Frequently Asked Questions About Heat Pump Installation
A standard replacement of an existing system usually takes one full day. A single-zone ductless mini split can often be finished in four to six hours. Multi-zone and geothermal installations take longer, from two days to a week for the loop field. We give you a time estimate with your written price.
Most air-source installations run between $4,500 and $12,000. Ductless mini splits start around $3,500 for a single zone, and geothermal systems start near $15,000. Every job includes a written price before work begins and the 365-Day Done Right Promise after. Call (817) 402-2972 for a free estimate.
Yes. Modern cold-climate heat pumps keep delivering heat at temperatures well below freezing, though output and efficiency drop as it gets colder. In very cold regions, we often pair a heat pump with a backup heat source. We’ll tell you honestly what to expect where you live.
Often yes. We check duct size, leakage, and condition first. Ducts that are too small or badly sealed can hurt performance, and we’ll put any needed repairs in your written price. If the ducts are beyond saving, a ductless system is a solid alternative.
We install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our technicians are trained on all nine, and we’ll recommend the model that fits your home and budget rather than pushing one brand.
Every installation includes the 365-Day Done Right Promise, a written guarantee valid for a full year from the date of service. If the work fails in that window, we return and correct it at no charge. Manufacturer equipment warranties apply separately, and we help you register them.
