Whole-Home Heat Pump and Electrical Service Upgrade in Reading, MA: Comfort, Efficiency, and EV-Ready Living

Energy-Efficient Comfort and EV-Readiness for a Mid-Century Ranch in Reading, MA

Homeowners in Reading, Massachusetts, are increasingly turning to energy-efficient upgrades that reduce fossil fuel dependence and prepare their homes for a fully electric future. For a 1951 single-family ranch home recently weatherized through local energy efficiency programs, the next step was a whole-home HVAC upgrade and electrical modernization.

Denommee Plumbing, HVAC & Electric was selected to deliver the full project scope: a cold-climate heat pump with ducted air distribution, a 200-amp electrical service upgrade, and a professionally installed electric vehicle (EV) charger. This all-electric transformation—backed by over $7,000 in local and federal incentives—highlighted Denommee’s unmatched coordination across trades and deep experience with utility-sponsored rebate programs.

Project Overview: 1951 3-Bedroom Ranch, 1,372 Square Feet

The home had recently undergone air sealing and insulation improvements, making it an ideal candidate for a cold-climate heat pump. The homeowners wanted to eliminate reliance on fossil fuels while improving indoor comfort and preparing the home for future electrification, including electric vehicle charging.

Denommee provided a turnkey upgrade including:

• Installation of a 2-ton ducted cold-climate heat pump system

• Full basement ductwork design and installation

• Complete 200-amp electrical service upgrade

• Installation of a hardwired ChargePoint EV charger

• Integrated Ecobee smart thermostat controls

• Seamless project management, permitting, and code compliance

High-Performance Heat Pump Equipment

At the core of this upgrade is a Custom Comfort 2-ton cold-climate heat pump system. Designed to maintain high output even in extreme cold, this system provides reliable heating through New England winters, while delivering efficient cooling during the summer.

Installed Equipment:

• Outdoor Unit: Custom Comfort CCOXHA24V24HP

  • Variable-capacity inverter compressor

  • Cold-climate performance down to -22°F

  • High heat output: 31,000 BTU at 47°F, 26,400 BTU at 17°F

• Indoor Unit: Custom Comfort 4-stage ECM air handler

  • Model: CCOXHAAH24V24

  • Multi-positional for flexible installation

• Efficiency Ratings:

  • SEER2: 17.4

  • HSPF: 10.0

  • COP at 5°F: 3.38

• Smart Controls: Ecobee Smart Thermostat Pro with remote sensors for balanced comfort

This system was carefully sized and configured to meet the home’s heating and cooling load, considering its layout and recent weatherization. The ECM air handler ensures quiet, responsive airflow with reduced energy consumption compared to traditional PSC blower motors.

Ductwork Designed for Comfort and Efficiency

In the home’s basement, Denommee’s sheet metal team installed a 2-ton capacity duct system, primarily constructed of galvanized steel for durability and airflow performance.

Ductwork Scope:

• Hard-pipe supply and return trunk system

• Fully sealed seams and insulated duct runs

• 4–5 supply registers and 1–2 return grilles

• Air filters, vibration isolation blocks, and 3-way diffusers

• Flood shutoff and proper condensate drainage systems

This attic-to-living space distribution system supports consistent comfort across all three bedrooms and living areas, avoiding the room-to-room temperature swings that plagued the old system.

Seamless Electrical Upgrades by In-House Electricians

One of the key advantages Denommee offers is in-house electrical expertise. For this project, Denommee electricians completed a comprehensive electrical service upgrade, replacing the outdated panel and preparing the home for future electrification.

Electrical Scope:

• Upgrade to 200-amp service

• Install new 40-slot breaker panel

• Install new AC feed for heat pump condenser

• Wire and install new attic air handler feed

• Supply and install hardwired EV charger

  • ChargePoint Home Flex, 50A capacity

• All wiring, whips, and disconnects installed to Massachusetts code

By coordinating all electrical work internally, Denommee minimized delays, ensured code compliance, and delivered a seamless customer experience—no need for the homeowner to hire a separate electrician or navigate permits independently.

EV Charger Installation: ChargePoint Home Flex

With Massachusetts leading the way in EV adoption, more homeowners are adding EV chargers during HVAC or electrical upgrades. Denommee installed a hardwired ChargePoint Home Flex, a Level 2 EV charger compatible with all major electric vehicle brands.

This future-proofs the home for EV ownership, adds convenience, and contributes to a fully electrified lifestyle.

Incentives and Financing: Over $7,000 in Savings

Because the new system replaced an aging fossil-fuel heating system, the project qualified for substantial local and federal incentives.

Rebates and Credits Earned:

• $3,750: Heat pump rebate from Reading Light, the local municipal utility

• $3,200: Federal 25C energy tax credit (30% of project cost up to $2,000 for heat pumps, plus $600 for panel upgrade and $600 for EV charger)

Additionally, Denommee is a Mass Save Heat Pump Installer Network (HPIN) member and Abode MLP-Approved Contractor, ensuring access to the best incentives, accurate paperwork, and stress-free compliance for rebate processing.
