Install & changeouts
High-efficiency furnace and AC swaps on older brick two-flats and North Shore homes. Clean work. We leave the mechanical room better than we found it.

Northline Comfort
When the heat dies at midnight — we’re already on the way.
We keep brick two-flats warm in January and cool when the city cooks. Installs, service, ductless, heat pumps — Marcus and the crew.
Same-night when we can. Written numbers before we touch the unit. If you call after dark, someone still answers.
What we do
Install · Repair · Ductless · More
Residential and light commercial HVAC for the North Shore and near-north suburbs. Furnace and AC changeouts, heat pumps, ductless for three-season porches, tune-ups before the freeze — and the no-heat / no-cool call that can’t wait.
Repair & diagnostics
Flat diagnostic fee — waived if you book the repair with us. Written estimate before we wrench. No bait-and-switch on the driveway.
Ductless mini-splits
Room-by-room comfort for additions, upstairs dens, three-season porches, and homes that never got proper duct runs — without tearing the place apart.
Heat pumps
Modern heat-pump installs and service for homes ready to cut winter gas bills without losing comfort when the lake wind hits.
Tune-ups
Spring cool check and fall heat check — filters, coils, safety switches, airflow — so January doesn’t surprise you at 2am.
Emergency
After-hours line for dead heat and no-cool nights. Same crew that knows Evanston alleys and Winnetka basements — not a random overnight dispatch board.
Where we roll
North Shore & near north
About a 25-mile radius from the shop. We live these streets — not “greater Chicagoland” vagueness.

After-hours
Midnight heat fails don’t wait
Shop runs Mon–Fri 7am–6pm and Sat 8am–2pm. Outside that, the emergency line still answers — so a dead furnace in January or a no-cool night doesn’t leave you in voicemail limbo until morning.
- No-heat and no-cool emergencies — same-night when we can
- Clear next-step windows, not a runaround
- Same Marcus crew that already knows your streets
Hours: Mon–Fri 7:00am–6:00pm · Sat 8:00am–2:00pm · After-hours emergencies open

The crew
Marcus & four techs
Marcus Hale runs the board — four techs and one apprentice on the helper bench. Installs, tune-ups, and the emergency that can’t wait. You get a tech who shows up, not a runaround.
- Licensed HVAC — residential & light commercial
- Upfront on what’s broken · written estimate
- Callbacks that actually happen
End of the call
Job done. Rolling home.
House warm again. Taillights on wet asphalt. We’re already rolling toward the next north-suburb street — job done, no lingering.
- Clean exit after written work
- Van leaves clean — warm windows behind us
- Same crew if you need us again tonight
