About Us
OUR STORY
John’s A-C & Heat has been serving South Jersey since 1975, when John Brown started the company with a pretty simple way of doing business: work hard, treat people right, do good work, and charge a fair price. More than 50 years later, we still believe that's the best way to run an HVAC company.

KEEPING JOHN’S GOING
Before Frank Zinni owned John’s, he worked for John Brown. Frank learned the business from John and got to see firsthand the relationships he had built with customers over the years. When Frank had the opportunity to take over the company in 2017, keeping the John’s name was important to him. John had spent decades building a good reputation in the community. Frank didn't want to change what was working. He wanted to keep it going. Today, our family owns and operates John’s, but we haven't forgotten where it started or the values the company was built on.
WHAT BEING FAMILY-OWNED MEANS TO US
We live here. We work here. We raise our families here.
Our customers aren't account numbers. They're people we're likely to run into at the grocery store, a restaurant, a ball field, or somewhere around town.
We want to be able to look people in the eye and know we treated them fairly. That means giving honest answers, explaining the options, doing quality work, and not pressuring someone into buying something they don't need.
Sometimes doing the right thing means making a smaller sale today.
We're perfectly okay with that.
We'd rather earn someone's trust and have them call John’s again years from now — or feel comfortable giving our name to their parents, kids, friends, and neighbors.
And when we talk about the John’s family, we don't only mean our last name.
Our technicians, installers, helpers, and office staff are a huge part of this company. We want John’s to be a place where good people enjoy coming to work, feel appreciated, learn and grow, take care of their own families, and are proud of the work they do.


SOME THINGS SHOULDN'T CHANGE
A lot has changed in the HVAC business since 1975.
The equipment is different. Technology is different.
The way people communicate is different. And we'll keep changing and improving right along with it.
But there are some things we don't think need changing.
- Answer the phone.
- Show up when you say you will.
- Explain things so people understand.
- Don't pressure people.
- Do good work.
- Stand behind it.
- And if something isn't right, make it right.
We're not trying to be the biggest HVAC company around.
We just want to be a really good local one.
That's what John started in 1975, and we're proud to keep it going.
