Installation Services in Greater Boston
A new system should be designed around your home, not selected from a price book. We measure the home, complete the required calculations and provide one clear recommendation with the full scope and price in writing before installation begins.
Design-First Installation
We Start With the Home, Not the Equipment
Two homes with the same square footage can require very different systems. Windows, insulation, sun exposure, room layout, existing ductwork and the way the home is used all affect what the system needs to do.
Every new installation begins with an in-home assessment. Most assessments take about 90 minutes because we measure the home, review the existing equipment and distribution, complete the required calculations and make sure the recommended system is properly matched to the house. We do not rush that process.
617 HVAC is a design-first company and a Mass Save® Heat Pump Installer Network contractor. We are also repair-first. When repairing the system you already own is the better answer, we say so before recommending replacement.

Replacement turns out to be the right decision.
Repair-First Still Applies
Told you need a full replacement?Get the diagnosis first.
When another company has recommended replacing the entire system, we test, measure and document it before agreeing that replacement is necessary.
Among the second-opinion calls we receive after another company recommends full replacement, our diagnosis supports repairing the existing system about 80% of the time. In the remaining one in five, replacement turns out to be the right decision.
When 617 HVAC recommends a new installation, it is because the measurements and condition of the system support it, not because replacement was the easiest thing to sell.

Installation FAQs
Frequently Asked Questions
How much does installation cost in Greater Boston?
Installation cost depends on system capacity, equipment selection, ductwork condition, electrical requirements, access and the complexity of the home. After the assessment and design work, you receive one detailed written proposal with the complete scope and price before you commit.
What is a Manual J load calculation?
Manual J is the residential HVAC standard used to calculate how much heating and cooling a home needs based on the actual building rather than a square-footage shortcut. Every new 617 HVAC installation includes Manual J and Manual S unless valid, current calculations have already been completed and can be verified. Manual D is also completed when ductwork is involved unless there is a documented reason it is not required.
How long does installation take?
Plan for one to two weeks for most installations. That allows time for disassembly, installation, rebuilding, testing, commissioning, inspections and final adjustments. Your written proposal will include the expected timeline for your project.
What Mass Save rebates apply to a new system?
Qualifying heat-pump projects may be eligible for rebates up to $8,500, with enhanced incentives up to $16,000 for eligible households. 617 HVAC reviews the available programs, completes and submits the required rebate paperwork and includes the applicable incentives in the written proposal.
What happens if hidden construction changes the installation plan?
Older homes can reveal framing, headers or other concealed conditions once walls or ceilings are opened. When that happens, we walk the project with you, explain what we found and adjust the routing or installation approach. Normal field adjustments within the approved scope do not change the project price.
Should I repair or replace?
Diagnose first. When another company has recommended full replacement, our diagnosis supports repairing the existing system about 80% of the time. When the findings support replacement, we explain why and show you what changed the decision.
