Climate Zones
Wellesley sits in IECC Climate Zone 6, which means cold winters (design temps down to -5°F) and warm summers (up to 91°F). This temperature range matters—your heat pump needs to handle both extremes efficiently. At Palmetto, we understand Wellesley's climate and can help you choose a system sized properly for year-round comfort. 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
Wellesley Electricity Prices
Wellesley residents face some of the highest electricity rates in the nation, making energy efficiency more important than ever.
Massachusetts electricity costs have climbed from 22.9 cents per kWh in 2021 to 29.3 cents in 2024—nearly double the national average of 16.5 cents per kWh.
Heat pumps offer a practical solution to rising energy costs. Because they're 2-3x more efficient than traditional HVAC systems, they use significantly less electricity to deliver the same heating and cooling.
As electricity rates continue to fluctuate, a heat pump's superior efficiency means lower monthly bills and predictable long-term savings—helping your home stay comfortable without the premium price tag.
Price of Energy: Massachusetts vs National Average
Wellesley Area Utility Providers
Wellesley residents receive electricity from two primary utilities: National Grid and Eversource. According to 2023 data, National Grid's rates averaged 36.7¢ per kWh, while Eversource averaged 29.7¢ per kWh—both exceeding the national average of 16.0¢.
Massachusetts electricity costs remain elevated due to the state's reliance on natural gas for power generation and limited pipeline infrastructure. Regional energy market dynamics and delivery charges further contribute to rates that consistently exceed national benchmarks.
While electricity costs in Wellesley run higher than average, heat pumps can still reduce your overall energy spending. Their efficiency—often delivering three units of heating or cooling per unit of electricity—means lower total bills compared to traditional systems, even at elevated rates.

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. |
