Climate Zones
Nashua sits in IECC Climate Zone 5, which means cold winters (design temps around -17°F) and warm summers (up to 85°F). This wide temperature swing matters when sizing your heat pump—you need a system that can handle both extremes efficiently. At Palmetto, we understand Nashua's climate and can help you find the right heat pump for your home. Explore other climate 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.
Climate Zone 1A
Avg. extreme winters: -60° to -55° F
Climate Zone 1B
Avg. extreme winters: -55° to -50° F
Nashua Electricity Prices
Understanding electricity costs in Nashua is essential when choosing your home heating and cooling system—especially with New Hampshire's rates climbing well above the national average.
New Hampshire residents have seen electricity costs jump from 19.9 cents per kWh in 2021 to 23.3 cents per kWh in 2024—consistently exceeding the national average by roughly 40% throughout this period.
Heat pumps offer a practical response to these rising rates. Because they're 2-3 times more efficient than traditional HVAC systems, they use significantly less electricity to deliver the same amount of heating and cooling to your Nashua home.
As electricity prices continue fluctuating, that efficiency advantage compounds over time. A heat pump's lower energy consumption means your monthly bills stay more manageable, helping protect your household budget against future rate increases for years to come.
Price of Energy: New Hampshire vs National Average
Nashua Area Utility Providers
Nashua residents receive electricity from Eversource, which charged 28.9¢ per kWh in 2023—slightly above New Hampshire's state average of 28.20¢ and notably higher than the national average of 16.0¢ per kWh.
New Hampshire's electricity costs remain elevated due to the state's reliance on natural gas and limited local generation capacity. Regional transmission constraints and peak demand during cold winters further drive prices above the national average.
While electricity rates run high in Nashua, heat pumps use energy so efficiently that they often reduce total heating and cooling costs compared to traditional systems. Their efficiency helps offset higher per-kilowatt-hour rates, making them a smart choice even in premium electricity markets.

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. |

HVAC is an umbrella term that stands for Heating, Ventilation, and Air Conditioning—it describes any system that controls your home's temperature and air quality. A heat pump is actually a specific type of HVAC system that both heats and cools your home by transferring heat rather than generating it through combustion, making it highly efficient even in Nashua's Climate Zone 5 conditions.
Unlike traditional HVAC systems that use separate furnaces and air conditioners, a heat pump handles both jobs with one unit. This efficiency matters in New Hampshire, where electricity costs 23.3¢ per kWh—heat pumps can significantly reduce your energy bills compared to older heating systems. Palmetto makes installation accessible through our Comfort Plan with $0 upfront or direct purchase options that may qualify for federal tax credits up to $2,000.
