Bradford Haverhill Heat Pump Conversion — Case Study

Property: 1962 residential single-family, Bradford neighborhood Haverhill
Owner: S.T. (property owner alias)
Scope: Aging gas furnace and central AC replaced with premium Carrier Infinity Greenspeed variable-capacity heat pump using existing ductwork; complete fossil-fuel elimination; installation led by Marcus Devlin, Bradford resident
Timeline: Diagnostic and design 2 weeks, installation 4 days
Investment: $30,800 installed, $10,000 Mass Save Whole-Home Heat Pump rebate, $2,000 IRA 25C federal tax credit, net $18,800; includes Rivic’s 10-year Carrier Infinity manufacturer warranty administration

Situation

S.T. owns a 1962 residential single-family property in the Bradford neighborhood of Haverhill. Bradford is a substantial Haverhill neighborhood south of the Merrimack River (the river divides Haverhill into main-side/north-side and Bradford/south-side) with diverse residential development from the mid-20th century subdivision era through more recent construction. Bradford is the largest of Haverhill’s neighborhoods by area given Haverhill’s 33.9 sq mi total footprint (largest city in Rivic’s service area).

Marcus Devlin — Rivic’s service manager and MA Journeyman Gas Fitter with 15 years of experience including specific involvement in the 2018-19 Columbia Gas relight response work — lives in Bradford with his family, in a comparable mid-20th century subdivision-era property approximately 12 minutes from S.T.’s property. Marcus’s residency in Bradford provides first-party neighborhood familiarity for Haverhill installations similar to Ryan Sullivan’s role for Dracut/Kenwood installations.

The 1962 property was significantly renovated in approximately 2005 including HVAC system replacement (20-year current gas furnace and central AC), kitchen renovation, and general modernization. The 20-year current gas furnace and central AC were operational but at end-of-life range with declining efficiency and reliability. Existing ductwork throughout the property from the 2005 HVAC scope in acceptable condition suitable for heat pump conversion.

S.T. requested Rivic assess replacement options with priorities: (1) coordinated replacement of the aging 2005-era HVAC systems given both approaching end-of-life range, (2) fossil-fuel elimination through heat pump conversion for Mass Save Whole-Home Heat Pump rebate opportunity, (3) premium equipment tier matching Bradford neighborhood market context, (4) preference for Marcus Devlin as installation lead given his Bradford residency (S.T. specifically requested Marcus for the assessment scope).

Diagnostic and Assessment

Marcus Devlin conducted the initial diagnostic assessment. Ryan Sullivan handled premium equipment specification support given the premium equipment tier scope.

Key findings: (1) 20-year 2005 gas furnace with declining efficiency (approximately 76-82% effective from 90% AFUE nameplate) but heat exchanger inspection did not reveal cracks or critical failure indicators, (2) 20-year 2005 central AC with declining efficiency and typical refrigerant charge decline for the equipment age, (3) existing ductwork from 2005 scope in good condition suitable for heat pump conversion, (4) 200A National Grid electric service adequate for heat pump installation with capacity margin, (5) property configuration well-suited to ducted heat pump installation replacing existing furnace/AC location.

ACCA Manual J load calculation determined property heating load at 4°F winter design of approximately 62,000 BTU/hr and cooling load at 88°F summer design of approximately 42,000 BTU/hr. Marcus recommended 5-ton premium cold-climate heat pump installation matching the calculated loads with margin.

Solution: Premium Carrier Infinity Greenspeed with Existing Ductwork Utilization

Rivic recommended premium Carrier Infinity Greenspeed variable-capacity heat pump 5-ton nominal capacity with existing ductwork utilization. Equipment specification: (1) Carrier Infinity 25VNA0 variable-capacity outdoor unit with cold-climate performance verified for 4°F winter design, (2) Carrier Infinity communicating platform integration with 5-stage part-load modulation, (3) Carrier Infinity indoor air handler with ECM variable-speed blower, (4) Carrier Infinity Touch communicating thermostat with mobile app integration, (5) 10-year Carrier Infinity manufacturer warranty on parts + compressor with Rivic warranty administration.

Existing ductwork utilization: minor duct sealing improvements at accessible joints; supply and return grille inspection confirmed adequate condition from the 2005 installation scope; variable-speed ECM blower matched to Carrier Infinity variable-capacity operation for optimized airflow.

Gas furnace and central AC decommissioning: 20-year 2005 equipment removed with proper refrigerant recovery per EPA Section 608; gas piping capped at previous furnace location. Marcus’s MA Journeyman Gas Fitter licensure appropriate for the gas equipment decommissioning scope.

Marcus Devlin’s Bradford Residency — First-Party Familiarity

Marcus’s residency in Bradford contributes specific first-party knowledge to installations in the neighborhood:

  • Bradford neighborhood configuration familiarity: Bradford includes diverse residential development from the 1940s post-war subdivision era through the 1950s-70s major subdivision expansion into more recent 1980s-2000s construction. Marcus’s own Bradford home shares construction era with much of the neighborhood, giving him direct familiarity with typical ductwork routing, mechanical space configuration, and Bradford-specific property patterns.
  • Haverhill utility framework familiarity: Haverhill uses National Grid for electric service (like North Andover and Dracut) and Eversource Gas of Massachusetts for gas service. Marcus’s residency and 15-year Merrimack Valley HVAC experience provides deep familiarity with National Grid Bradford electric service patterns and Eversource gas service in Haverhill.
  • Same-day service accessibility: Marcus’s Bradford residency enables faster response to warranty service or diagnostic requests from Bradford customers — same-day response typical compared to 24-48 hour typical response from Rivic’s Methuen office location for other service areas.
  • 2018 Columbia Gas relight experience: Marcus’s specific involvement in the 2018-19 Columbia Gas relight response gives him direct familiarity with Merrimack Valley gas equipment configurations across many properties, including similar systems in Bradford Haverhill. While Haverhill was NOT in the 2018 affected zone, Marcus’s response experience provides broad familiarity with 1980s-2000s gas equipment installations of the type replaced in this case study.

Haverhill NOT in 2018 Columbia Gas Affected Zone

Similar to Dracut and North Andover, Haverhill was NOT in the September 13, 2018 Columbia Gas over-pressurization affected zone (which affected portions of Lawrence, Andover, and southern Methuen only). Standard Haverhill gas installations do not require amended-code documentation from the 2018 event. Haverhill is served by Eversource Gas of Massachusetts (formerly Columbia Gas after the 2020 sale) with standard MA Fuel Gas Code (527 CMR 5.00) compliance and standard installation practices.

Outcome

Installation completed over 4 days including outdoor Carrier Infinity 25VNA0 placement on side-yard concrete pad (adjacent to original central AC condenser location), indoor Carrier Infinity air handler installation in basement replacing gas furnace location, ductwork sealing improvements, refrigerant charging, communicating platform commissioning, and mobile app configuration. Marcus Devlin led the installation team on all 4 days.

Post-installation first-year operational verification: heat pump operated reliably through the first winter including cold-snap periods with outdoor temperatures reaching 2°F to 5°F range. Carrier Infinity variable-capacity operation delivered efficient part-load performance across seasonal load patterns with communicating platform coordination.

Ongoing Operating Cost Change

Post-installation first-year utility monitoring: total electric operating cost approximately $1,540 for combined heating and cooling. Previous year utility costs: gas heating approximately $1,720 (declining efficiency 20-year furnace), electric cooling approximately $620 (declining efficiency 20-year AC), combined approximately $2,340/year. Annual operating cost reduction approximately $800/year.

Investment Summary

  • Total installation cost: $30,800 (Carrier Infinity Greenspeed 5-ton equipment, communicating platform components, air handler with ECM blower, installation labor, ductwork improvements, refrigerant charging, commissioning)
  • Mass Save Whole-Home Heat Pump rebate: $10,000 (fossil-fuel elimination qualifying)
  • IRA 25C federal tax credit: $2,000
  • Net investment: $18,800 after all rebates and tax credits
  • Annual operating cost reduction: approximately $800/year
  • Additional value: 10-year Carrier Infinity manufacturer warranty with Rivic warranty administration; Marcus Devlin resident first-party service accessibility for Bradford Haverhill customers; substantially improved reliability

Frequently Asked Questions About This Case Study

Does Marcus Devlin personally handle all Bradford Haverhill installations?
Marcus leads Bradford Haverhill installations when scheduling permits, and Bradford customers can specifically request Marcus for their installation scope. Marcus’s Bradford residency provides first-party neighborhood familiarity including property configuration familiarity, National Grid electric service and Eversource gas service familiarity across Haverhill, and same-day service response accessibility. On installations where Marcus is not available (vacation, scheduled service elsewhere, scheduling conflicts), Rivic’s other senior technicians (Andrew Samples, Ryan Sullivan) or Diego Ramirez handle the installation scope with Rivic’s consistent quality standards. Warranty service and diagnostic scope from Bradford customers is generally routed to Marcus when available; when unavailable, other Rivic technicians provide standard 24-48 hour response scope.
Can Rivic install a similar heat pump conversion in my Bradford or other Haverhill neighborhood property?
Yes for properties with suitable configuration. Prerequisites: adequate 200A National Grid electric service (typical for mid-20th century and later subdivision construction; older Bradford properties may have 100A service requiring careful load coordination or service upgrade), existing ductwork suitable for reasonable airflow at heat pump capacity, and reasonable property size matched to heat pump capacity range. Rivic’s diagnostic assessment includes heat pump conversion feasibility evaluation. Typical cost range for similar Bradford or other Haverhill heat pump conversions: $22,000-$40,000 gross depending on equipment tier and property size, $10,000-$28,000 net after Mass Save Whole-Home rebate and IRA 25C credit.
How does Haverhill’s utility framework compare to other Merrimack Valley cities?
Haverhill uses National Grid for electric service (like North Andover and Dracut) and Eversource Gas of Massachusetts for gas service. This matches North Andover and Dracut utility framework and differs from Andover, Lawrence, and Methuen (Eversource both electric and gas). Practical differences: National Grid customer service (800-322-3223) handles electric-side inquiries; Eversource Gas of Massachusetts handles gas-side inquiries including gas emergencies (800-592-2000). Mass Save Whole-Home Heat Pump rebate framework is consistent across both utilities. Haverhill was NOT in the 2018 Columbia Gas affected zone (unlike Lawrence and southern Methuen); standard Haverhill gas installations do not require amended-code documentation. Rivic’s diagnostic and installation service scope is consistent for Haverhill regardless of the utility framework.
Was Haverhill affected by the 2018 Columbia Gas incident?
No. The September 13, 2018 Columbia Gas over-pressurization event affected portions of Lawrence, Andover, and southern Methuen only. Haverhill was NOT in the affected zone; standard Haverhill gas installations do not require amended-code documentation from the 2018 event. Haverhill is served by Eversource Gas of Massachusetts (formerly Columbia Gas after the 2020 sale) with standard MA Fuel Gas Code (527 CMR 5.00) compliance and standard installation practices. This differs from Lawrence and southern Methuen properties where amended-code coordination applies. Marcus Devlin’s specific involvement in the 2018-19 Columbia Gas relight response was for affected-zone properties in Lawrence and Andover; that experience provides broad familiarity with Merrimack Valley gas equipment configurations relevant across the service area even for Haverhill installations that are not directly related to the 2018 event.
What’s the typical cost range for Bradford Haverhill premium heat pump installations?
Typical range: $22,000-$40,000 gross depending on property size and equipment configuration. This case study’s $30,800 total reflects premium Carrier Infinity Greenspeed 5-ton with communicating platform. Smaller property installations (3-ton systems) typically cost $22,000-$28,000 with premium equipment; larger property installations can cost $34,000-$46,000+. Mid-tier alternatives (Bosch IDS 2.0) typically cost $18,000-$26,000 for comparable property scope. Mass Save Whole-Home Heat Pump rebate ($10,000) and IRA 25C credit ($2,000) apply consistently regardless of equipment tier. 10-year manufacturer warranty administration included at no additional charge on qualifying premium installations.
