Straight answers

Asked often.

Do you repair systems, or only replace them?

We repair first. If your furnace or AC still has safe, economical life left, we'll fix it and tell you so. Replacement only enters the conversation when the repair math stops making sense — and we'll show you that math.

How fast can you get a technician to me?

Same-day service across Markham and much of the GTA for most calls. Our emergency line runs 24/7 for no-heat and no-cool situations.

Which equipment brands do you install?

All the major ones — Carrier, Daikin, Lennox, Trane, Goodman, Rheem, York, Amana, Ruud, Napoleon, Bryant, and American Standard.

What is the Iron Shield Maintenance Plan?

Proactive care with free labour. Seasonal tune-ups plus free labour on covered repairs and transparent, agreed-upfront pricing.

Do you serve my town?

If you're in York Region, Durham, or Toronto, almost certainly. Daily routes through Richmond Hill, Vaughan, Scarborough, Pickering, Ajax, Whitby, Oshawa, Newmarket, Aurora, and Stouffville.

No heat at 2 a.m.?
We answer.
