About Summit

Three generations, one phone number.

Summit has answered MetroWest's heating and cooling calls from the same office on Cochituate Road since 1998.

How it started

Mike's grandfather opened Summit in 1998 with one truck and a rule he wrote on the inside of the van door: say what's wrong, say what it costs, then do the job. The door is long gone. The rule is how every estimate is still written.

What's changed

Almost everything about the equipment. The refrigerants are different, heat pumps went from a curiosity to most of our installs, and the diagnostic tools now tell us in minutes what used to take an afternoon.

Summit has been a Carrier Factory Authorized dealer since 2011, which means warranty claims go straight through Carrier instead of bouncing between offices.

What hasn't

The phone still rings to the Sullivans, 7 to 7 on weekdays and 8 to 4 on Saturdays. Quotes are still written before a tool comes out of the truck. And we still work the same twelve towns, close enough to the shop that a callback is a short drive, not a scheduling problem.

Who's on the line

The Sullivans answer the phone.

I started here at 17, riding shotgun on my dad's truck. Now I run the company my grandfather started in 1998 — and the phone still rings to the same office on Cochituate Road. Most days I'm the one who picks it up.

The work has changed. Refrigerants are different, heat pumps got serious, the diagnostic tools are real now. The promise hasn't: we tell you what's wrong, what we'd do at our own house, and what it'll cost. Then we do that — on time, the first visit when we can.

If you want a flashy sales pitch, plenty of bigger shops have one. If you want someone who'll still pick up in five years, that's us.
