HVAC in Birmingham, MI — sized by math, not by habit.
Furnaces, cold-climate heat pumps, and mini-splits for radiator homes — sized by load calculation, coordinated end to end, with DTE rebate paperwork handled.
Heating and cooling decisions never live alone.
Here's a scene we see all over Birmingham. A gorgeous 1930s house near Quarton Lake. Original radiators — silent, warm, honestly kind of wonderful. No ducts anywhere. And every July, box fans in the windows and a second floor you could bake bread in.
For decades, the answer to “how do we get air conditioning in this house” was ugly: cut duct chases through plaster walls, lose closets, spend a fortune. That answer has changed, and it's one of the main reasons to read this page.
Endura coordinates HVAC in Birmingham, MI as part of a construction group. That matters because heating and cooling decisions never live alone. The right furnace size depends on your insulation. A heat pump conversion depends on your electrical panel. A mini-split plan depends on your plaster walls. We plan those pieces together, with experienced mechanical contractors doing the installation, the trades coordinated, and rebate paperwork filed.
HVAC scope we coordinate.
Furnace replacement
Gas furnaces last around 15 to 20 years. A planned fall replacement beats a January emergency on price and on choices — and every unit gets sized by a Manual J load calculation, not by matching the old one.
Air conditioning installation
Central AC for ducted homes, sized right. An oversized AC cools fast but never runs long enough to pull out humidity — which is why some houses feel cold and clammy at the same time.
Cold-climate heat pumps
Modern inverter-driven units pull heat from outdoor air down to around -15°F. Dual-fuel setups pair one with a gas furnace that takes over automatically on the coldest days.
Mini-splits for radiator homes
A three-inch wall penetration instead of duct chases through plaster. Room-by-room control that also fixes the roasting-second-floor problem — the least invasive path to comfort in Birmingham's historic housing stock.
Boiler service & replacement
Well-maintained boilers run 30 years or more, and we'd never talk you out of a healthy one. At end of life, we lay out boiler, dual-fuel, and electrification options side by side — with the panel and gas-line implications of each.
Coordination & DTE rebate filing
HVAC rarely happens alone — we coordinate the mechanical work with the electrical, gas-line, and wall-repair pieces around it, and DTE rebate paperwork is filed by a participating contractor, with amounts date-checked before we promise anything.
Do heat pumps actually work in Michigan winters? Yes — here's the math.
Cold-climate heat pumps hold capacity down to roughly -15°F. Metro Detroit's design temperature — the benchmark cold that systems here are sized against — is about 6°F above zero. That's inside the working range, with margin.
Michigan homes are best served by equipment sized with a Manual J load calculation. An oversized furnace short-cycles — blasts on, shuts off, repeats — wearing parts and leaving rooms uneven. Bigger is not better. Right is better. Your house isn't the house it was when the old unit went in.
DTE rebate on qualifying cold-climate heat pumps — the largest residential HVAC rebate on their sheet as of mid-2026.
DTE rebate on qualifying ductless mini-splits replacing electric heat.
DTE rebate on high-efficiency (95%+ AFUE) gas furnaces; central AC runs $100–$300.
Rebate funds deplete during each program year. A participating contractor files the paperwork — we coordinate the filing and confirm current amounts first. Figures as of July 2026.
Electrifying your heating often raises the panel question: many older Birmingham homes need 200-amp service to support it. We check that before anyone orders equipment, because we also handle the electrical side.

When this makes sense, and when it doesn't.
Call us when
Your furnace or AC is past 15 years and you'd rather replace on your schedule.
You have radiators, no ducts, and a second floor that bakes every July.
You're weighing a heat pump, dual-fuel, or full electrification.
A renovation is changing insulation, layout, or loads.
You want the rebate paperwork handled, not handed to you.
You don't need us when
Your furnace died on a Friday night in January. Call a 24-hour service company — you need heat tonight, not a coordinator. Endura is for planned work: replacements, conversions, radiator-home retrofits, and the mechanical scope inside renovations.
A radiator house, cooled without a single duct.
1930s boiler home, zoned room by room
A radiator-heated home with no ducts and an unbearable second floor. The plan: cold-climate mini-splits with three-inch wall penetrations, the boiler kept as backup, and the panel capacity confirmed before equipment was ordered.
Result: Whole-home cooling and shoulder-season heat, no duct chases cut, plaster and millwork untouched.
Common questions about HVAC in Birmingham.
Something specific to your house? Ask us directly.
Do heat pumps really work in Michigan winters?
Yes. Cold-climate models hold capacity down to roughly -15°F, and our area's design temperature is about 6°F. Dual-fuel setups add a gas backup for the deepest cold.
What's a dual-fuel system?
A heat pump paired with a gas furnace. The heat pump runs most of the season; the furnace takes over below a set temperature. Efficiency most days, muscle on the worst ones.
How do we add AC to a radiator-heated house?
Ductless mini-splits, in most cases. Three-inch wall penetrations instead of duct chases, room-by-room control, and no sacrificed closets.
Why does sizing need a “Manual J” instead of matching my old unit?
Because your house isn't the house it was when that unit went in — and the old unit may have been wrong to begin with. Oversized systems short-cycle and dehumidify poorly. The load calculation sizes to the actual house.
How long should equipment last?
Furnaces and central AC, 15–20 years. Air-source heat pumps, 10–15. Boilers, 15–20, often 30+ with care. Mini-splits, 15–20.
What rebates are available right now?
As of mid-2026, DTE offers up to $400 on high-efficiency furnaces, $100–$300 on AC, $700–$1,000 on qualifying mini-splits, and $900–$1,200 on cold-climate heat pumps. Funds deplete during the year. We confirm current amounts and file the paperwork.
