Climate Zones
Nashua sits in USDA Hardiness Zone 5, where winter design temperatures can reach -17°F and summer design temperatures reach 85°F. That means a heat pump needs to deliver reliable heat through long, cold spells while still keeping homes comfortable on warm, humid days. Palmetto understands Nashua’s seasonal conditions and can recommend a system sized for local needs. Explore other zones below or enter your ZIP code to confirm yours.
Climate Zone 1
Climate zone 1 is not typically seen within the United States outside of Alaska. It represents the coldest climates on the planet.

Nashua Electricity Prices
For Nashua homeowners, electricity prices have shifted—but remain above the national average.
New Hampshire’s average electricity price rose from 19.9¢ per kWh in 2021 to 28.2¢ in 2023, then eased to 23.3¢ in 2024. That was still above the U.S. average of 16.5¢.
Heat pumps can provide two to three times as much heating or cooling per unit of electricity as conventional HVAC systems, helping limit the electricity needed to keep your home comfortable.
By handling both heating and cooling efficiently, a properly sized heat pump can help manage energy costs over time as rates change. Results depend on your home, energy use, and utility rates.

Nashua Area Utility Providers
In Nashua, Eversource is the utility listed here. The latest available figures are from 2023, not 2024: electricity cost 28.9¢ per kWh, compared with New Hampshire’s 28.20¢ and the national average of 16.0¢.
Eversource’s 2023 rate was 0.70¢ per kWh above the state average and 12.9¢ above the national average. The national figure combines places with different electricity prices, so it can be lower than a local utility’s rate.
Heat pumps move heat rather than generate it directly, making them highly efficient. That efficiency can help lower total energy spending compared with traditional HVAC, even when electricity costs are high. Actual savings depend on the home and system.

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.
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. |
