What we do
Full-service HVAC, top to bottom.
From a single mini-split in a guest room to rooftop packaged units on a multi-tenant commercial building — we design, install, and service it all.
Heating
Furnaces, boilers, hydronic systems, and modern heat pumps. Service, replacement, or full new-construction installs.
Indoor Air Quality
Whole-home filtration, humidification, dehumidifiers, ERVs, and ventilation upgrades that actually move the needle.
Service & Maintenance
Spring-and-fall tune-ups, diagnostics, repairs, and priority maintenance plans that keep equipment running and warranties intact.
Commercial HVAC
Rooftop units, VRF, chillers, boilers, and make-up air for offices, retail, restaurants, and multi-tenant buildings.
Design & Build
Mechanical design for renovations, additions, and new construction — load calcs, equipment selection, and clean ductwork detailing.
Our story
Family owned since 1977. Built for what's next.
HPC Mechanical was built by tradespeople who came up through the field — running residential service routes, managing commercial new-construction projects, and learning what makes an HVAC company actually worth calling back.
We carry forward nearly five decades of HVAC experience and a familiar mascot most Fairfield County homeowners already know — wrapped in a modern operation with licensed technicians, transparent pricing, a new commercial division, and the responsiveness today's homeowners and property managers expect.
- Hands-on owners who still work the field
- Licensed CT technicians, fully insured
- New commercial team built for larger projects
- Honest quotes — no upsells, no surprises

Word of mouth
Connecticut neighbors, talking.
A few recent comments from homeowners and businesses we've worked with across Fairfield County.
"Replaced our central AC and added a mini-split for the office above the garage. Crew showed up on time, kept the work area clean, and walked us through the new thermostat. The house has never been this comfortable in summer."

Greenwich, CT — Residential install
"We brought HPC in for a rooftop replacement on our retail building. Clean install, smart staging, finished a day ahead of schedule. They communicate the way you wish every contractor would."

Samantha R.
Stamford, CT — Commercial RTU replacement
"Furnace died on the coldest night of January. They had a tech at the house before noon the next day and a quote for a new system the same afternoon. Fair price, no nonsense."
