A local team that treats your home like our own
Locally owned by Rosario Thomas and based right here in Canal Winchester, Ohio.
Our story
Started with one van and a simple promise
Rosario Thomas spent more than a decade working for larger HVAC outfits around Columbus. The work was good, but the business side often wasn't: commissioned sales, high-pressure replacement pitches, and customers who felt they'd been talked into something.
Mando Air Heating & Cooling was founded to do it differently. We are a small, family-run company. Our technicians are paid for doing quality work, not for selling equipment. When a $180 repair will give your furnace another five good years, that's what we'll recommend.
Today our team serves homeowners, landlords and small businesses throughout Fairfield, Franklin, Pickaway and Licking counties from our office at 4545 Samoyed Dr #304, Canal Winchester, OH 43110.
What we stand for
Our values
Honesty first
We explain what we find, show you photos, and never invent problems. If it's not broken, we'll tell you.
Respect for your time
Two-hour arrival windows and a text when your technician is on the way.
Craftsmanship
Proper line sets, sealed ducts, level pads, and code-compliant wiring. Work we'd be proud to put in our own homes.
Community
We sponsor local youth sports and offer discounted service to seniors and veterans in our area.
Credentials
Licensed, insured and trained

Kind words from customers
“Our furnace died the Sunday before Thanksgiving. Rosario's tech was in our basement within three hours and had it running again for less than I expected. Honest people.”
“They talked me out of a full replacement and fixed the blower motor instead. That alone earned them a customer for life.”
“Clean install of a Trane heat pump, shoe covers, drop cloths, walked us through the thermostat. Electric bill dropped about 20% the first summer.”
“We use Mando Air for our two restaurant rooftop units. Scheduled maintenance, clear reports, no surprises.”
