Local Incentives

McKinney, TX Heat Pump Rebates & Incentives

Local and federal incentive programs can significantly reduce the cost of a new heat pump system. Here are the programs available to McKinney homeowners.

Oncor Home Energy Efficiency

Up to $3,400

Oncor’s 2026 program provides incentives for qualifying high-efficiency heat pump replacements through participating service providers. The per-system cap reaches $3,400 for a 5-ton system, but the actual customer incentive varies and depends on available program funding.

Eligibility: The home must have active Oncor electric delivery service, and the project must use an approved participating service provider. Qualifying high-efficiency central, ground-source, and mini-split heat pumps are listed; applications are accepted through December 4, 2026, or until funding is exhausted.

Learn more →

For McKinney homes with Oncor electric delivery service, Oncor’s 2026 Home Energy Efficiency program offers incentives for qualifying heat pump replacements, with actual amounts depending on equipment, the participating provider, and remaining funds. Palmetto can help homeowners check utility and equipment eligibility and work with an eligible installer to apply for and maximize available savings.

Incentive information is based on publicly available data as of 2026 and may change. Contact program administrators to verify current availability and eligibility requirements.

Climate Zones

McKinney is in USDA Hardiness Zone 10, with design temperatures of 33°F for heating and 95°F for cooling. That means winters are mild but can bring cold snaps, while summers are hot. These conditions matter when sizing a heat pump for comfort and efficiency. Palmetto understands McKinney’s climate and can recommend a system suited to it.

McKinney Electricity Prices

For McKinney homeowners, electricity prices are part of the long-term cost of keeping a home comfortable.

The chart shows Texas’s average electricity price rising from 12.1 cents per kilowatt-hour in 2021 to 14.9 cents in 2024. The national average also increased, from 13.7 to 16.5 cents.

Heat pumps can deliver two to three times more heating or cooling per unit of electricity than traditional HVAC systems, helping meet your comfort needs while using less power.

Using less electricity for the same comfort can help limit the impact of rising rates over time. Actual savings depend on your home, energy use, and electricity plan.

McKinney Area Utility Providers

In McKinney, CoServ customers paid an average 12.8¢ per kilowatt-hour in 2023. The chart compares that local figure with Texas’s 14.50¢ and the national average of 16.0¢; 2024 data isn’t available yet.

CoServ’s 2023 average was below both benchmarks. Electricity prices can differ by utility because rates reflect local service and power costs, but the figures provided don’t identify a specific reason for CoServ’s lower average.

Even where electricity costs are high, a heat pump’s efficiency can help limit the electricity needed for heating and cooling. That may lower total HVAC energy spending compared with traditional systems, though results depend on the home and usage.

Repair versus replace

When a heat pump is in need of repair it is worth considering whether a replacement would be a better investment. While each case is unique, we generally recommend investing in a new unit when repairs exceed $5,000.

$5,000
Recommended repair threshold

A heat pump's lifetime is impacted by a number of factors including environment, use and the quality of the unit. It's important to choose the right unit for your climate zone and home's unique attributes.

When you are in need of repair, we recommend choosing a service provider that is an expert in the heat pump brand you have installed, and checking online reviews to ensure you are investing in the right level of service.

Potential repair Cost range Description
Capacitor Replacement $150 - $400 Common issue when unit struggles to start or makes a humming noise. Capacitors store the electrical energy needed to start the compressor and fan motors.
Refrigerant Recharge $250 - $750 Needed when the system loses cooling or heating efficiency due to low refrigerant levels. Includes leak detection, repair of minor leaks, and recharging the system to the manufacturer-specified level.
Reversing Valve Replacement $450 - $900 Required when the unit cannot switch between heating and cooling modes. The reversing valve directs refrigerant flow and is unique to heat pump systems.
Compressor Replacement $1,500 - $3,000 Major repair needed when the unit fails to heat or cool entirely. The compressor is the heart of the system, circulating refrigerant between the indoor and outdoor coils.
Evaporator/Condenser Coil Replacement $1,200 - $2,800 Replacement needed when coils develop leaks or corrosion that cannot be economically repaired. Coil damage reduces heat transfer efficiency and can cause refrigerant loss.
Control Board Replacement $500 - $1,200 Required when the system has electrical failures or erratic behavior. The control board manages all system operations including defrost cycles, fan speeds, and compressor staging.
Full System Replacement $4,500 - $8,000+ When repairs exceed the value of the unit or multiple major components fail simultaneously. Includes removal of the old system and installation of a new heat pump with updated refrigerant lines and electrical connections.

Frequently Asked Questions

Yes—heat pumps can make sense in McKinney because the area’s Climate Zone 10 winters are relatively mild: the design heating temperature is 33°F, while the design cooling temperature reaches 95°F. One system can provide both heating and cooling. At Texas’s electricity price of 14.9¢ per kWh, actual bills depend on equipment efficiency, home insulation, and usage.

Heat pumps are generally efficient in McKinney’s climate because winters are relatively mild. McKinney is in Climate Zone 10, with a design heating temperature of 33°F and design cooling temperature of 95°F. Since heat pumps move heat instead of making it, they can deliver more heat than the electricity they use; actual efficiency depends on equipment, sizing, and installation.

At the supplied Texas electricity price of 14.9¢ per kWh, your bill depends on the heat pump’s seasonal efficiency, thermostat settings, home insulation, and electricity plan—not climate alone. Palmetto offers a Comfort Plan with maintenance and repairs included, or direct purchase; a qualified installer can estimate usage for your home.

In McKinney, lease through Palmetto’s Comfort Plan if you prefer $0 upfront, a predictable monthly payment, and maintenance, repairs, and warranty coverage included for the plan’s life.

The right option depends on your budget and ownership preferences.

For either route, ask the installer to size the equipment for McKinney’s Climate Zone 10 conditions: a 33°F design heating temperature and 95°F design cooling temperature. A proper assessment helps match system capacity to your home. Direct purchasers may qualify for state or utility rebates where available; no federal heat pump tax credit applies to systems installed in 2026.

HVAC stands for heating, ventilation, and air conditioning; it describes systems that control indoor temperature and air quality. A heat pump is one type of HVAC equipment. Unlike a furnace paired with an air conditioner, it moves heat indoors in winter and outdoors in summer, so one system can provide both heating and cooling.

In McKinney’s Climate Zone 10, design temperatures are 33°F for heating and 95°F for cooling, conditions a properly sized heat pump can serve. At a Texas electricity price of 14.9¢ per kWh, actual costs depend on efficiency, usage, and the electric plan. Palmetto offers a $0-upfront lease with maintenance and repairs included, or direct purchase, which gives homeowners ownership.
