Rosemont Heating & Air · Whitlock, Tansy Green & the Oxbow roads · family-run since 1987

We will leave your house warmer than we found it, or we will tell you we cannot — in writing, with the numbers, before you pay us anything.
Delia Rosemont — second-generation owner, third on the trucks each December

My father started this company with one truck, one gauge set and a rule he wrote on the shop wall: never sell a machine to a house that needs a repair. I have run the place since 2009, my daughter runs the service ledger, and the rule is still on the wall — we have just added the load-calculation software beside it.

What that means for you, practically: the combustion analyzer comes out before any opinion does, the Manual J runs before any equipment is priced, and every figure we leave on your kitchen table is one you can hold us to. Thirty-eight years in, most of our January calls come from houses we have kept honest for a decade.

Heating, the old-fashioned promise

Furnaces and boilers repaired when a repair is honest, replaced when it is not — and the combustion printout that decided it goes home with you either way.

Cooling sized by arithmetic

SEER2-rated systems and cold-climate heat pumps, sized by Manual J instead of folklore, with the utility rebate paperwork done by us before you see an invoice.

Twice-a-year house calls

The same two techs, spring and fall, on a schedule we keep for you — readings logged to the house’s file so its whole history lives in one folder.

How it goes

How a Rosemont visit goes

The same sequence on every job — the only variable is your project.

  1. The call

    Someone who knows the house

    If you have called before, the file is open before the phone is — your system’s history, its readings, the last thing we fixed. If you are new, we start one.

  2. Day one

    Measured, not guessed

    Combustion, static pressure, temperatures: the instruments go on before the opinions come out. The visit ends with numbers on your table and no obligation attached to them.

  3. That evening

    The honest option first

    We write up what the house needs — sometimes a $260 part, sometimes a system — and the write-up says which one and why. Repairs beat replacements here about two times in five.

  4. The work

    Our hands, our name

    No subcontracted installers: the people who measured the house are the people in it, and the truck that arrives carries the parts the file said it would.

  5. Every season after

    The folder grows

    Spring and fall visits append readings to the house’s history, so the year something drifts, the answer is on an old page instead of in a stranger’s guess.

The big franchise told my mother her furnace was “on its way out” and quoted nine thousand dollars. Rosemont came, put the analyzer on, showed her 0 ppm and a sound exchanger, and replaced a pressure switch. That was four winters ago. Mrs. Rosemont still sends a card at Christmas — my mother sends two.
Ellen Tsosie — Whitlock, second-opinion call that became the family’s house call
Three generations of this family have worked on our houses — my parents’, mine, and now my daughter’s first home. The folder passed along with the keys. Try finding that at a call centre.

They ran the Manual J in front of me and the unit they recommended was smaller and cheaper than the two quotes on my counter. Six winters on, the bedroom over the garage is the warmest room in the house.

Our fall visit is booked by them, confirmed by text, and kept to the half hour. When the ignitor died on Christmas Eve, the tech who came had our file on his phone and the part on his truck.

Asked on the porch

Are you really the ones who answer?

Delia, her daughter Marta, or Curtis, who has driven the second truck since 2011. No answering service, no franchise number, and after hours the phone rings in the house of whoever is on call — which in December is usually mine.

What if the honest answer is a bigger company?

Then we say so. A collapsed commercial roof system at midnight needs a fleet, and we will tell you which one to call while we are still on the line. The rule is about your house, not our revenue — it has cost us work and never once cost us a family.

Do you handle the new refrigerants?

Yes — the trucks carry the A2L-rated gauges and the certification for R-32 and R-454B as R-410A phases down, and every replacement quote lists the refrigerant beside the SEER2 and HSPF2 ratings. Your grandfather’s furnace and next year’s heat pump are both within the practice.

What is the House File, exactly?

A folder with your address on it, holding every reading any of us has ever taken in your house. Plan members get it maintained — two visits a year, priority dispatch in January — and it transfers with the house when you sell. Buyers have rung us because the folder was left on the counter.

How far out do you book?

House calls run about two weeks out in the quiet seasons and longer at the first cold snap; emergencies are never queued behind them. Installs are typically three to five weeks from the day you sign the write-up.

The rate card changes every January. The practice behind it has not changed since 1987: the whole price, on the wall, before anyone drives.
