Massachusetts HVAC Done Right.

Heat pumps with up to $10,000 Mass Save rebate. Boilers, central AC, ductless mini-splits, tankless water heaters, ductwork. Mitsubishi Hyper-Heat, Fujitsu XLTH, Bosch IDS 2.0 cold-climate certified — every install Mass Save HPC filed and warranty-registered.

HVAC in Massachusetts is no longer about replacing oil with gas. The Commonwealth's Climate Roadmap Act targets 1 million heat pump installations by 2030, backed by the most aggressive rebate program in the country. Mass Save covers up to $10,000 on cold-climate heat pumps; the HEAT Loan finances the rest at 0% APR. Pro Build Home Services & Construction is an authorized HPC — we file every rebate, install only R-32 and R-454B refrigerant systems, and run an ACCA Manual J load calculation on every project.

Why Massachusetts HVAC Is Different

Three forces make Massachusetts the most distinctive HVAC market in the country, and most generic contractors aren't equipped for any of them:

  1. Mass Save is real money. Up to $10,000 cash back per heat pump install, $1,250 per ton on multi-zone mini-splits, $750–$1,500 on heat pump water heaters, $15,000+ on geothermal. Income-eligible homeowners frequently qualify for enhanced rebates above the standard cap. Hiring a non-HPC contractor forfeits all of it.
  2. refrigerant rules. The federal AIM Act phased out R-410A for new equipment. Mass Save followed: only systems using R-32 or R-454B qualify rebates. Stock equipment from contractors who haven't updated is now disqualified.
  3. Boston housing stock predates 1978. EPA RRP lead-safe handling is required for any work disturbing painted surfaces — common when running refrigerant lines, line sets, or thermostat wires. RRP-certified crews only.

The Brands We Install

Equipment selection drives long-term performance. We install only AHRI-matched systems from manufacturers with proven cold-climate performance and Massachusetts service networks:

  • Mitsubishi Hyper-Heat (cold-climate flagship)
  • Fujitsu XLTH (cold-climate, multi-zone)
  • Bosch IDS 2.0 (whole-home ducted)
  • Carrier Greenspeed
  • Trane XV20i, XL20i
  • Lennox SL28XCV
  • Navien tankless & combi
  • Rinnai tankless
  • Buderus hydronic boilers

How a Pro Build HVAC Project Works

  1. Free Manual J load calculation. ACCA-standard heat-load calculation, ductwork inspection, electrical panel capacity check. This step alone is what most contractors skip.
  2. System design with brand options. Right-sized specification with multiple manufacturer options. Performance projections at 5°F and -13°F. AHRI matched documentation.
  3. Mass Save rebate calculation. Exact rebate by system, capacity, and homeowner income tier. Income-eligible enhancements verified against current Mass Save tables.
  4. Permits + paperwork. 780 CMR mechanical permit, electrical permit if panel upgrade required, Mass Save HEAT Loan filing. We file everything.
  5. Installation. 1–2 days for ductless. 2–4 days for whole-home ASHP. 1–2 weeks for geothermal. EPA RRP containment for pre-1978 homes.
  6. Commissioning + warranty registration. Refrigerant charge to spec, airflow balanced, electrical safety check, manufacturer warranty registered, Mass Save post-install verification submitted.

Cross-Trade Coordination That Matters

Most Massachusetts HVAC projects depend on other trades. We hold the licenses in-house so the project doesn't bounce between contractors:

  • Heat pump install + 200-amp panel upgrade. Most pre-1990 MA homes need panel headroom for a heat pump. We coordinate as one project.
  • HVAC + Mass Save insulation + air sealing. Insulating before sizing the heat pump shrinks the load — sometimes by 30–40%. Smaller system, lower bills, lower install cost. Mass Save rewards bundles.
  • HVAC + gas line work. Boiler install, tankless water heater, gas-fired furnace — all need gas line sizing or relocation. Master Plumber/Gas Fitter on staff.
  • HVAC + basement finishing or whole-home renovation. Ductwork goes in walls and ceilings before drywall. Plan it together.

HVAC FAQs

Massachusetts HVAC Questions Answered.

How much does heat pump installation cost in Massachusetts after Mass Save rebates?

Whole-home cold-climate air-source: $5,000–$18,000 net after $10,000 Mass Save rebate. Multi-zone ductless mini-split: $4,750–$8,500 net. Geothermal: $10,000–$30,000 net after $15,000+ rebate. Income-eligible homeowners often qualify for enhanced rebates that bring net cost to zero in some cases.

Do heat pumps actually work in Massachusetts winters?

Yes. Modern cold-climate models — Mitsubishi Hyper-Heat, Fujitsu XLTH, Bosch IDS 2.0 — maintain 100% rated capacity at 5°F and continue operating down to -22°F. Boston averages only 3–7 days per year below 5°F. For Berkshire County and northern Worcester, we routinely specify dual-fuel pairings for the rare extreme cold snap.

What changed in Mass Save heat pump rebates ?

Currently, Mass Save no longer rebates heat pumps using R-410A refrigerant. Only R-32 and R-454B systems qualify, driven by the federal AIM Act phase-down. We install only R-32 and R-454B compliant equipment.

Are you a Mass Save authorized installer (HPC)?

Yes. Pro Build is an authorized Mass Save Heat Pump Contractor (HPC). We submit and track every rebate application at no extra cost. Over $2.1 million in Mass Save rebates secured for Massachusetts homeowners since 2018.

Do you provide 24/7 emergency HVAC service?

Yes. Boiler failure during cold snaps, AC failure during heat waves, water heater leaks, gas-fired equipment shutdowns — all dispatched 24/7 within Greater Boston and same-day for outer Massachusetts. Emergency call-out fee credited toward repair if you proceed.

Can a single heat pump replace my entire heating system?

For most Massachusetts homes — yes. A correctly sized cold-climate heat pump replaces oil, propane, or gas heat completely. Confirmed during ACCA Manual J load calculation. For homes with extreme heat loads or limited electrical capacity, we sometimes recommend dual-fuel (heat pump + gas backup) instead.

Do I need a panel upgrade for a heat pump or EV charger?

Often yes for pre-1990 MA homes still on 100-amp service. A heat pump pulls 40–60 amps; an EV charger another 50. Most homes need a 200-amp panel upgrade for the headroom. We coordinate the electrical and HVAC scope as one project — single permit pull, single project manager.

How long does HVAC installation take in Massachusetts?

Ductless mini-split: 1–2 days. Whole-home air-source heat pump: 2–4 days. Geothermal: 1–2 weeks (ground-loop trenching). Boiler swap: 1–2 days. Central AC: 1–3 days. Panel upgrade if required: +1–3 days. Timeline confirmed in your written estimate.
