F.M. owns a rural single-family residential property in the northern part of Haverhill. Rural northern Haverhill includes properties away from downtown Haverhill’s mill district and Bradford’s mid-20th century subdivision development — the more rural areas of Haverhill maintain substantial propane retention pattern similar to western Dracut’s Pelham NH border area. Rural northern Haverhill properties are typically on larger lots (1-3+ acres) with the propane retention pattern reflecting the historical lack of natural gas distribution infrastructure extending to the more rural residential areas.
F.M.’s property configuration: approximately 2,400 sq ft two-story residential on approximately 1.5 acres, forced-air propane furnace serving ducted distribution throughout, matching central AC installed with the propane furnace approximately 16 years ago, 500-gallon aboveground propane tank in side-yard (aboveground rather than underground, per F.M.’s preference at time of previous installation), propane water heater in basement mechanical space.
F.M. and family are Spanish-speaking; F.M. has preference for Spanish-language coordination throughout installation project scope. Rivic’s Diego Ramirez provides bilingual English/Spanish coverage — Diego lives in Prospect Hill Lawrence and is a Greater Lawrence Technical grad, and his bilingual capability provides accessible service to Spanish-speaking customers throughout Rivic’s service area. F.M.’s Haverhill installation is an example of Diego’s bilingual scope extending beyond Lawrence (where Diego’s Spanish-language service is particularly high-demand given Lawrence’s approximately 82% Hispanic population) to serve Spanish-speaking customers in Haverhill’s approximately 24% Hispanic community.
F.M. requested Rivic assess replacement options with priorities: (1) fossil-fuel elimination through heat pump conversion for Mass Save Whole-Home rebate opportunity, (2) coordination throughout project in Spanish for clear communication, (3) propane operating cost reduction given the ongoing propane price fluctuation, (4) complete propane elimination including aboveground tank decommissioning.
Diego Ramirez conducted the initial diagnostic assessment (given F.M.’s Spanish-language preference). Ryan Sullivan handled premium equipment specification support given the premium equipment tier scope.
Key findings: (1) 16-year propane furnace with declining efficiency but not yet at end-of-life; F.M. requested proactive replacement given propane cost trajectory and coordinated modernization scope, (2) 16-year central AC also with declining efficiency and typical refrigerant charge decline, (3) existing ductwork in acceptable condition suitable for heat pump conversion with minor sealing improvements, (4) 200A National Grid electric service adequate for heat pump installation with capacity margin, (5) 500-gallon aboveground propane tank requires licensed propane contractor for decommissioning — aboveground tank decommissioning is generally simpler than underground tank scope (no excavation required; tank recovery straightforward through licensed propane contractor pickup).
ACCA Manual J load calculation determined property heating load at 4°F winter design of approximately 50,000 BTU/hr and cooling load at 88°F summer design of approximately 34,000 BTU/hr.
Rivic recommended premium Carrier Infinity Greenspeed variable-capacity heat pump 4-ton nominal capacity with existing ductwork utilization. Equipment specification: (1) Carrier Infinity 25VNA0 variable-capacity outdoor unit, (2) Carrier Infinity communicating platform 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 (Diego provided Spanish-language walkthrough of thermostat operation and mobile app configuration for F.M.), (5) 10-year Carrier Infinity manufacturer warranty on parts + compressor with Rivic warranty administration.
Existing ductwork utilization: minor duct sealing improvements at accessible joints; variable-speed ECM blower matched to Carrier Infinity variable-capacity operation.
Propane furnace and central AC decommissioning: 16-year equipment removed with proper refrigerant recovery per EPA Section 608; propane piping capped at previous furnace location.
Aboveground propane tank decommissioning is generally simpler than underground tank scope described in the Western Dracut Pelham NH border case study. Kathleen Brennan coordinated licensed propane contractor for the aboveground tank decommissioning:
Diego’s bilingual English/Spanish service capability provides accessible installation and service coordination for Spanish-speaking customers throughout Rivic’s Merrimack Valley service area:
Rivic supports bilingual service coordination as part of installation project management at no additional charge. Customers with Spanish-language preference can request Diego for their installation scope during initial contact.
Installation completed over 5 days for HVAC scope plus 1 additional day for propane tank decommissioning. Diego led installation coordination throughout with Ryan Sullivan supporting the premium equipment installation scope. Diego’s bilingual coordination ensured clear communication with F.M. throughout the installation process including daily progress updates, coordination on specific installation activity impacts, and post-installation training on the Carrier Infinity communicating platform operation.
Post-installation first-year utility monitoring: total electric operating cost approximately $1,580 for combined heating and cooling. Previous year utility costs: propane heating approximately $2,240 (16-year furnace declined efficiency plus propane price fluctuation), electric cooling approximately $560 (16-year AC declining efficiency), combined approximately $2,800/year. Annual operating cost reduction approximately $1,220/year — typical for propane-to-heat-pump conversions given propane’s higher cost per BTU vs natural gas.
Rural northern Haverhill and Merrimack Valley rural residential HVAC service including propane-to-heat-pump conversion, licensed propane contractor coordination for aboveground and underground propane tank decommissioning, Diego Ramirez bilingual English/Spanish coordination for Spanish-speaking customers throughout Rivic’s service area, Mass Save Whole-Home Heat Pump rebate coordination for propane conversion scope, and IRA 25C federal tax credit coordination all route through our 225 Broadway #306 office in downtown Methuen. This case study represents a specific installation completed for F.M.; individual property assessments determine equipment specification and installation scope.
