About Andes HVAC

An HVAC repair company serving North Jersey — six days a week, on buildings that already exist.

Our Story

We fix what's already there

Andes HVAC is built on a simple promise: show up when we said we would, find out what is actually wrong before quoting anything, and leave the property the way we found it. We have grown almost entirely by word of mouth across Montclair, Ridgewood, Summit, Westfield and the rest of North Jersey — one satisfied neighbor at a time.

We work exclusively on existing homes and buildings. That is a deliberate choice, not a limitation. A house that is already finished and lived in is a completely different job from a rough-in on a new build: the ductwork is where it is, the line set has to be routed through finished walls, the boiler sits where a boiler has sat for eighty years, and nobody wants their ceilings opened up. That is the work we are set up to do, and doing only that is why we are good at it.

Today we handle central air conditioning repair, gas and oil boiler repair on steam and hot-water systems, mini-split repair and installation, and rooftop AC repair. We are open Monday through Friday, 9 AM to 5 PM, and Saturdays 9 AM to 2 PM, and every estimate is free.

What We Stand For

Reliability

We show up on the day we said, at the time we said. If something moves the schedule, you hear it from us first.

Respect

It's your home. We put covers down, work clean around the mechanical room, and take the old equipment away with us.

Diagnose, Don't Guess

Gauges on the ports, amp draw measured, controls checked in order. No parts replaced hopefully and billed anyway.

Community

We live here too. We work local, and our reputation travels by word of mouth rather than advertising.

Our Mission

Keep North Jersey homes comfortable through both halves of the year, on the equipment they already have, for as long as that equipment is worth keeping. Treat every customer like a neighbor, because most of them are. Earn the next referral with the work itself.

Our Promise

We'll tell you honestly whether a unit is worth repairing — including when the answer costs us the bigger job. And if you're not happy with the work, tell us and we'll come back and make it right. That's how we've built a customer list that runs almost entirely on referrals.
