Index 001 — Full-service HVAC contractor
Ambassador Dearie HVAC installs, repairs, and maintains furnaces, air conditioners, and heat pumps for homes and small businesses across Ottawa. Technicians who show up on time, quote honestly, and leave your basement cleaner than they found it.
High-efficiency gas furnace installation, honest diagnostics, and repairs that actually fix the problem. We size every unit to the house — never oversold, never undersized — and we tell you plainly when a repair is smarter than a replacement.
Central air conditioning installed right the first time, plus refrigerant, electrical, and airflow repairs on the systems you already own. Ottawa summers are short; a well-tuned AC makes every one of them comfortable.
Year-round heating and cooling in one system, built for Ottawa weather. Modern cold-climate heat pumps keep working far below freezing, and a dual-fuel setup with your existing furnace covers the coldest snaps.
Efficiency assessments, aging-system upgrades, and straightforward advice on cutting energy use. We look at the whole house — equipment, ductwork, controls — and rank upgrades by what actually pays back.

You describe the problem or the project. We ask the questions that matter and give you a straight read on what it probably is.
A technician comes out, looks at the equipment, the ductwork, the house. No guessing from a desk.
One written price before any work starts. If something changes mid-job, you hear it from us first — not on the invoice.
Clean work, protected floors, and a system tested before we pack up. Installations are sized and documented properly.
We show you what was done, how the new controls work, and what's covered. Then we answer the phone if anything ever feels off.
Furnaces, AC, and heat pumps for Ottawa houses — from century-old Glebe homes with finicky ductwork to new builds in the suburbs. Annual maintenance plans keep everything running and catch small problems before January does.
Based in Ottawa, on the road to the surrounding towns every week.

Once a year, before heating season. A fall tune-up catches worn parts, keeps efficiency up, and is the single best way to avoid a no-heat call in January.
Age plus repair frequency. If the unit is 15+ years old, needs frequent repairs, your bills keep climbing, or it's getting noisy — replacement usually beats another repair.
Yes — with the right model. Cold-climate heat pumps work far below freezing. On the coldest nights, a dual-fuel setup lets your furnace take over seamlessly.
Filter, thermostat, outdoor unit. A clogged filter, a thermostat set wrong, or leaves packed around the outdoor condenser cause most "no cooling" calls. If those check out, call us.
Call to ask about free estimates. We always inspect before we quote — no price is ever invented over the phone.
Tell us what's going on and we'll get back to you with next steps — usually the same business day.
