AC Repair
Warm air, weak airflow, leaks or a system that won’t start — we diagnose the cause before quoting the fix.

Repair Services in Greater Boston
When something is not working correctly, we test the system, document what we find and explain the repair options before work begins.
Repair-First Introduction
Diagnose the problem before deciding what comes next.
Different HVAC problems can create similar symptoms. Warm air, weak airflow, unusual noises, water, ice, short cycling or a system that will not start may point to very different causes.
617 HVAC begins with testing and measurement — not assumptions. We document the findings with photos, video and system readings, explain the diagnosis and provide the repair price in writing before work begins.
Our technicians are paid to do the job correctly — not to earn a commission from selling replacement equipment.

Heat Pump Repair
Heating and cooling from one system means more to check. We test the full cycle, not just the symptom.
Heat Pump RepairWhat Happens During a Repair Visit
A defined process from diagnosis to decision.
- 01
Step 1 — Listen and Inspect
We start with what you’ve noticed — the sounds, smells or changes in performance — then inspect the system, its controls and the conditions around it before touching…
- 02
Step 2 — Test and Measure
We take real readings — temperatures, pressures, electrical values and airflow — to find what the system is actually doing, rather than guessing from symptoms.
- 03
Step 3 — Document the Findings
We record what we find with photos, video and system readings, so the diagnosis is backed by evidence you can see.
- 04
Step 4 — Explain the Diagnosis
We walk you through what is wrong, what is causing it and which repair options make sense — in plain language, with no pressure.
Repair Pricing Overview
Know how the visit is billed before we arrive.
Repair service begins with a service reservation, mobilization and a diagnostic process. Diagnostic time begins when the technician starts testing and measuring — not when the technician arrives.
Once the problem is identified, the recommended repair is priced separately, in writing, for your approval.
Repair First Does Not Mean Repair at Any Cost
Repair when practical.Replace when the findings support it.
Repair-first is a starting point, not a rule. When a repair makes practical and financial sense, that is the recommendation.
But when repeated failures, unavailable parts, equipment condition or the long-term math point the other way, we explain that too — and show you what changed the decision. The goal is not to force a repair or push a replacement. It is to give you enough to make the right call for your home.
About 80%
We find a repairable problem about 80% of the time.

Second Opinions
Told you need replacement?Get the diagnosis first.
When another company has recommended replacement, we test, measure and document the system before agreeing that replacement is necessary.
Among the second-opinion calls we receive after another company recommended replacement, we find a repairable problem about 80% of the time. In the remaining one in five, replacement turns out to be the right decision.
When the findings support replacement, we explain why and show you what changed the decision.
