New HVAC system installations, whole-house replacements, and retrofit projects across the Merrimack Valley — sized to ACCA Manual J load calculations, selected via ACCA Manual S against the 4°F winter design and 88°F/72°F summer wet bulb, permitted through the appropriate municipal building department, and commissioned with documented combustion analysis and refrigerant charge verification. The Rivic installation process runs seven defined steps from initial contact through final commissioning, with typical timeline 3 to 4 weeks for non-emergency projects and 48 to 72 hours for emergency winter replacements drawing from Rivic’s inventory of common-configuration equipment.
Every installation Rivic pulls a permit for is filed under Massachusetts Home Improvement Contractor registration #HIC-191847, backed by the $10,000 statutory bond under M.G.L. c. 142A. Gas installations answer to Marcus Devlin’s Journeyman Gas Fitter license #JGF-30521 under 527 CMR 5.00 as amended post-2018. Refrigerant work runs through Andrew Samples’s EPA Section 608 Universal certification #608U-2007-192874 with independent 608 credentials for every technician.
Predominant Merrimack Valley installation category, driven by rising oil prices, tightening emissions rules, and the availability of Mass Save HEAT Loan financing at 0% APR. Typical scope: remove existing oil boiler and oil tank (site remediation per MassDEP guidelines), install Weil-McLain Ultra or Buderus GB142 modulating-condensing gas boiler, chimney reline through original masonry flue with 316L stainless-steel liner, new gas piping from Eversource meter to boiler location, new gas piping to any additional appliances (water heater, dryer, cooktop), permit filing with the appropriate municipal building department, commissioning with documented combustion analysis. Total project cost: $14,500 to $22,000 before Mass Save rebates. Timeline: 3 to 5 days on-site.
Growing rapidly under the Mass Save Whole-Home Heat Pump rebate up to $10,000 per home. Typical scope: remove fossil-fuel system (oil boiler, gas furnace, or gas boiler), install Mitsubishi Hyper-Heat MXZ multi-zone outdoor unit driving four to five interior zones with wall cassettes, ceiling cassettes, floor consoles, or ducted air handlers, all sized to Manual J load. Electrical service upgrade may be required (100-amp panel upgrade to 200-amp is common for pre-1970 homes). Mass Save HEAT Loan pre-approval, Whole-Home rebate paperwork, IRA Section 25C tax credit documentation. Total project cost: $18,000 to $28,000 before rebate. Timeline: 3 to 5 days on-site.
Signature Lawrence, Haverhill, and Methuen installation category. 1890s to 1920s three-family wood-frame housing with plaster-and-lath walls, no existing duct pathways, and cast-iron radiator hydronic heat that stays or is replaced separately. Typical scope: three-zone Mitsubishi MSZ-FS or Fujitsu Halcyon HFI system with wall cassettes in each unit, concealed line-set routing through porch cavities and exterior chases, one outdoor MXZ multi-zone condenser. Historic District Commission review where applicable (Rocks Village Haverhill, Andover Center, Old Center North Andover, Searles-Tenney-Nevins Methuen). Total cost: $12,000 to $18,000 for three-zone. Timeline: 3 to 4 days across two technicians.
Common upgrade for mid-century Merrimack Valley Colonials, Capes, and ranches that were built with forced-hot-air heating but no cooling. Existing furnace is retained if condition warrants; new evaporator coil sized to Manual S added to supply plenum, new R-454B condenser installed on pad or side-of-house bracket, new refrigerant line-set routed to indoor coil, condensate drain routed to appropriate termination. Total cost: $6,800 to $11,400. Timeline: 1 to 2 days.
Regency at Methuen, Village at Russell Farm, Tuscan Village Salem NH, Stone Castle Estates, and comparable subdivisions. Manual J load calc must account for R-49 attic, R-30 spray-foam walls, triple-pane glazing, and ACH50 below 1.5. Typical Manual J result: cooling load 30-40% lower than rule-of-thumb tonnage. Mechanical ventilation required (HRV or ERV) per ASHRAE 62.2 and Massachusetts Stretch Energy Code. Systems typically 2 to 2.5-ton central AC paired with 90%+ AFUE modulating gas furnace or cold-climate heat pump.
Installation quote requests, Manual J load calc consultations, and Mass Save rebate eligibility verification route through the 225 Broadway office in central Methuen. Kathleen Brennan handles quote scheduling and financing; Ryan Sullivan and Andrew Samples handle on-site specification review.
