Who we serve

Residential and commercial.

Single-family homes, offices, retail, warehouses, and multi-unit buildings. Same senior tech, same fixed-quote process. After-hours scheduling when service disruption isn't an option.

  • Residential

    Single-family homes, townhomes, and condos across the GTA.

  • Commercial

    Offices, retail, warehouses, and multi-unit buildings — light to mid-size. After-hours scheduling when service disruption isn't an option.

What we do

Heating, cooling, plumbing, gas — one owner, one invoice.

Heating, cooling, water, air, plumbing, gas lines, and seasonal maintenance — every category handled in-house by 11 dedicated services. No sub-contracting, no hand-offs.

What happens when you call

Anatomy of a service call.

Three steps. No surprises. Here's exactly what happens from the moment you pick up the phone to the moment we leave your driveway.

Step 01

Call us

A real person answers — not a dispatcher, not a call centre. We triage on the phone, confirm scope, and give you a real ETA before the tech leaves.

2–4 hours typical response in the GTA core
Step 02

Diagnose with real measurements

Senior licensed tech on-site. We diagnose with actual readings — gas pressure, combustion analysis, static pressure, refrigerant levels — and give you a fixed quote in writing before any parts come off the truck.

No guesses · No scope creep on the invoice
Step 03

Fix it, warranty it, move on

Repair or install done to code. Post-work performance check. Warranty terms printed on the invoice. If we did our job right, you won't hear from us until the next tune-up.

1-year labour warranty · Parts per manufacturer

We install, you own

Run your own numbers.

Adjust the sliders to match your current rental payment and term. The left side is what you'll hand over in total monthly payments — the right side is what owning the same equipment outright would cost. No contract, no monthly payment stream, no surprises at resale.

Rent over the term $11,700
Own outright $6,500

Own-outright number reflects a typical residential install range; your actual quote depends on equipment sizing, existing ductwork, and accessibility. Already on a rental? Call (416) 258-2460 and we'll walk you through the real buyout math.

Our standards

Three things we commit to, every call.

These are the non-negotiables. Same-day response, a senior licensed technician on every job, and a written warranty on every invoice.

You own the equipment

Every furnace, AC, and water heater we install is yours from day one. Fixed price in writing, manufacturer warranty registered in your name, never a rental contract.

Senior tech, every call

Param or a senior licensed technician runs every call from quote to commissioning. You get real measurements — gas pressure, combustion, static pressure, refrigerant — not a guess.

Same-day response

No-heat and no-cool calls get triaged to the front of the day. Most GTA-core calls run 2–4 hours door-to-door, with a real ETA before we dispatch.

Brands we service

Every major brand on the truck.

We service every major HVAC manufacturer sold in Ontario. Common failure parts — ignitors, capacitors, flame sensors, contactors — stay stocked on the truck so most repairs are same-day.

  • Carrier
  • Lennox
  • Trane
  • Goodman
  • Mitsubishi
  • Bryant
  • Rheem
  • York

"Brands we service" indicates familiarity and parts availability — not manufacturer endorsement. Authorized-dealer logos will be added once Param confirms active programs.

Mississauga is home base. The inner ring is our same-day-normal zone; the outer ring is where we travel for the right job — up to two hours out.

FAQ

Questions we get a lot.

Do you charge for a quote?
No — replacement and install quotes are free. For diagnostic calls on a broken system, there's a flat service-call fee disclosed before we drive out. If you approve the repair, it's credited to the job.
How fast can you actually get here?
Most GTA-core calls get same-day service, with a real ETA before we dispatch. No-heat and no-cool calls during cold snaps or heat waves get triaged to the front of the day.
Why shouldn't I rent instead of own?
Over 15 years, rental programs typically cost two to three times as much as owning the same equipment — and the rental contract follows the house if you sell. We install to own, and help you get out of existing rentals.
Do you work on every brand?
Yes — Lennox, Carrier, Trane, Goodman, York, Amana, Rheem, Bryant, and most others. We stock common failure parts on the truck.
Are you licensed and insured?
Yes. TSSA F/S F/S-7864-0125, HRAI member, fully insured. Owner-operated by a BSc. Certified HVAC Technician with 25+ years on the tools. Licence numbers printed on every invoice.
Do you handle commercial work?
Yes — offices, retail, warehouses, and multi-unit buildings. Furnace and AC service, rooftop units, commercial hot water, gas line build-outs. Permit coordination and after-hours scheduling to avoid service disruption.
