Real installed price ranges for furnaces, air conditioners, heat pumps, and repairs in Cambridge — and the factors that move your quote up or down.
Every year Cambridge homeowners tell us the same thing: they got three quotes and couldn't tell why they were thousands of dollars apart.

What moves a furnace quote up or down
- Size and staging. A 40,000 BTU single-stage for a Preston bungalow costs far less than a 100,000 BTU modulating unit for a large two-storey. Proper sizing comes from a heat-loss calculation, not the old unit's label.
- Efficiency tier. 96% two-stage is the Cambridge sweet spot. Modulating + ECM premium models add comfort and shave gas bills but add $1,000–$2,500 upfront.
- Venting and house age. Galt century homes often need new PVC venting routed through thick masonry, chimney liner abandonment, or condensate pumps — commonly $500–$1,500 of the spread.
- Ductwork corrections. Starved returns and undersized trunks are common in older Preston and Galt homes; fixing them during the install is cheap compared to living with a noisy, uneven system.
- Timing. An emergency swap in a January cold snap costs more than a planned fall replacement — one more reason not to nurse a 15-year-old Hespeler builder furnace through another winter.
AC and heat pump pricing
Central AC replacements ($4,000–$7,500) vary mostly with tonnage, SEER2 rating, and whether the indoor coil and lineset are reused or replaced. In Cambridge's humid summers, right-sizing is the number that matters — an oversized AC cools fast but leaves the house clammy.
Cold-climate heat pumps ($6,000–$14,000) span a wide range because the category does: a hybrid setup that pairs with your existing furnace sits at the lower end, while full-electric cold-climate systems with backup elements sit at the top. Enbridge's 2026 rebate programs apply to qualifying installations and can materially change the net price — often making a heat pump cost little more than a plain AC. We confirm current eligibility and file the paperwork as part of the quote.
Repair costs
Most Cambridge repair visits land between $150 and $600 — igniters, flame sensors, capacitors, contactors, condensate pumps, and the like, diagnosed and fixed in one trip. Big-ticket repairs (heat exchangers, compressors, control boards on aging equipment) get a written quote plus an honest repair-versus-replace comparison. Rough rule: if the repair exceeds a third of replacement cost and the unit is past 12 years, replacement usually wins.
Frequently asked questions
How much does a furnace replacement cost in Cambridge in 2026?
Most Cambridge homes pay $4,500–$8,500 installed for a high-efficiency gas furnace. The low end covers straightforward swaps in newer Hespeler and Preston homes; the high end reflects larger homes, modulating equipment, or venting and duct corrections common in Galt century homes.
How much does a new air conditioner cost in Cambridge?
Central AC installation typically runs $4,000–$7,500 installed, depending on tonnage, SEER rating, and whether the coil and lineset need replacing. Right-sizing matters more than brand in our humid Grand River summers.
What does a heat pump cost, and what rebates are available in 2026?
Cold-climate heat pump installs run $6,000–$14,000 depending on capacity and whether it's a hybrid (with gas backup) or full-electric setup. Qualifying installs are eligible for Enbridge rebate programs in 2026, which can significantly reduce the net cost — we confirm current amounts and handle the paperwork.
What does an HVAC repair visit cost?
Typical repair call-outs in Cambridge run $150–$600 including diagnosis and common parts like igniters, flame sensors, and capacitors. Major repairs are quoted in writing with a repair-versus-replace comparison.
Is it cheaper to replace my furnace and AC at the same time?
Usually, yes — combining them saves roughly $500–$1,000 in overlapping labour, and it opens up hybrid furnace-plus-heat-pump configurations that qualify for the best 2026 rebates.
Why do quotes vary so much between Cambridge contractors?
Differences in equipment tier, whether the quote includes venting/electrical/permit work, and whether the contractor sized the system properly. A cheap quote that skips the load calculation often costs more over ten years. Insist on an itemized written quote.
