Full furnace replacements sized with proper load calculations — no guesswork.
Markham homeowners call us for furnace installation because we know the area: Markham's newer developments mean more high-efficiency furnaces and central AC under warranty — and more homeowners who need a technician who won't void that warranty with the wrong repair. Duct-sizing issues that leave some rooms never quite comfortable are also common in newer builds here. Whether you're in Unionville, Cornell, Berczy Village and Milliken, we give you an honest on-site assessment and a straight answer.
A furnace that's the wrong size costs you money every month it runs, whether it's oversized and short-cycling or undersized and struggling. We size every replacement with a proper heat-load calculation for your actual home, not a rule of thumb, and install high-efficiency units correctly so you get the efficiency you paid for and keep your manufacturer warranty intact.
You get transparent pricing, proper preparation, and workmanship that holds up to real GTA winters — the details that separate a job that lasts from one that fails in year two.
