AC and Furnace Combo Cost in Toronto: 2026 Bundle Pricing Guide

By the Megacity HVAC teamPublished April 29, 2026Reviewed by our TSSA-certified technicians

Replacing your AC and furnace together saves 15–25% versus doing them separately. Toronto homeowners are paying $7,500 to $22,000 for a bundled install in 2026. Here is the actual math, what is included, and when bundling makes sense.

Why Bundle

Why Bundle AC + Furnace Replacement in Toronto

The cooling coil sits directly above the furnace blower. They share ductwork, refrigerant lines, electrical, and the same thermostat. When you replace one, you are already inside the other. Bundling collapses overlapping costs.

One Crew, One Trip, One Commissioning

A combo install uses the same two-technician crew across both systems. You pay one mobilization, one set of refrigerant evacuation tools, one commissioning report. Doing them separately means paying that overhead twice.

Equipment Compatibility from Day One

Matched AFUE furnace and SEER2 AC means the blower CFM is sized for the cooling coil, the refrigerant type matches, and the controls speak the same protocol. No surprise upgrades 18 months later when the mismatch shows up.

Ask About In-House Rebates

Megacity offers in-house rebates on combo installs. Ask about them at your quote. Toronto homeowners can also look into the low-interest BetterHomesTO HELP loan, which they apply for directly.

One Permit, One ESA, One TSSA

A single combined permit covers both units. One ESA electrical inspection. One TSSA gas inspection on the furnace side. Doing it twice across two seasons means two permit fees and two inspection bookings.

The Math

How Much You Save vs. Replacing Separately

The savings on a combo install are not marketing fluff, they are real line items that disappear when you bundle. Most Toronto homeowners save about $965 to $1,800 on the combined install, before any in-house rebate compared to running two separate projects 18 months apart.

Shared crew labour (one mobilization vs. two)$400 – $700

Single permit fee (City of Toronto / municipal)$120 – $250

Single ESA electrical inspection$95 – $150

Combined refrigerant evacuation and brazing setup$200 – $400

In-house rebates (ask at your quote)Varies

Single commissioning + warranty registration visit$150 – $300

Typical Total Savings$965 – $1,800

The bundle does not just pay you back faster, it costs less to do in the first place.

When Not To Bundle

When Bundling Is the Wrong Call

Bundling is not always the right move. We will tell you to wait if any of these apply. Replacing healthy equipment to chase a rebate almost never pencils out.

Furnace Is Under 8 Years Old

Modern furnaces routinely last 18–22 years with maintenance. Replacing one at year 6 to bundle with a dying AC means walking away from 12+ years of useful life. Replace the AC alone and bundle the furnace later.

AC Is Under 10 Years Old

A healthy AC at 8 years has another 5–7 years left. Pair the new furnace with a service tune-up on the existing AC instead. Reassess in 5 years when the AC is genuinely near end-of-life.

Capacity Mismatch Forced by the House

Some homes need a much larger furnace than AC, or the reverse, due to insulation upgrades, additions, or basement finishing. A communicating combo system loses its value when one side is oversized to compensate.

Budget Is Genuinely Tight

A failed AC in July does not need to be solved by spending an extra $5,000 on a furnace that is fine. Replace what failed, finance it cleanly, and revisit the bundle when the second unit shows real wear.

Sizing

Sizing and Equipment Matching

Manual J load calculation is non-negotiable. A proper sizing run looks at insulation R-values, window U-factors, infiltration rates, ceiling height, orientation, and occupant load. Sizing by square footage alone is how oversized systems get sold, and oversized systems are the single biggest comfort and reliability problem in Toronto homes.

Oversizing is the number one mistake in HVAC. An oversized furnace short-cycles, blasting the house with hot air for 4 minutes then shutting off. The blower never moves enough air to balance temperatures between rooms. An oversized AC drops the temperature fast but never runs long enough to dehumidify, leaving the house clammy at 22°C. Both shorten equipment life and burn more gas and electricity than a correctly sized system.

ECM blower compatibility matters. Modern variable-speed AC condensers expect a variable-speed ECM blower in the furnace. If you are pairing a 2-stage or inverter AC with a single-stage PSC furnace, you lose half the comfort benefit you paid for. Match the airflow technology across both sides.

Refrigerant lineset and refrigerant type. The 2025 phaseout of R-410A means most 2026 installs use R-454B or R-32. The line set diameter, fittings, and oil compatibility differ. We pressure-test and flush existing line sets before reusing them, and replace them outright if they are undersized or contaminated.

Thermostat and controls. Some variable-speed communicating systems require brand-matched controls to unlock full modulation. Mixed-brand combinations may fall back to conventional 24V control and lose advanced features. We confirm thermostat compatibility on the quote, not on install day.

Install Day

Timeline and What to Expect on Install Day

A standard combo install takes 6–10 hours with a two-technician crew. Bigger jobs with line set replacement, panel upgrades, or duct modifications run into a second day. Here is the standard sequence.

Arrival and Walk-Through (15–30 min)

Crew confirms equipment matches the quote, reviews the install plan, lays drop cloths, and shuts down power, gas, and refrigerant lines. You sign off on the scope before any cutting starts.

Demo and Refrigerant Recovery (1–2 hrs)

Old AC is recovered to EPA standards, refrigerant captured in a recovery tank. Old furnace is disconnected, vented, and removed. Old line set is inspected, pressure-tested, or replaced.

New Furnace Install (2–3 hrs)

New furnace set in place, gas line connected, venting routed, condensate trap installed, electrical hooked up. Cooling coil cabinet mounted on top, brazed and pressure-tested.

New AC Install (2–3 hrs)

Outdoor condenser set on a new pad, line set brazed, system pressure-tested with nitrogen, vacuumed to 500 microns, then weighed in with refrigerant. Condensate pump and overflow safety installed.

Commissioning and Inspections (1–2 hrs)

Full commissioning: thermostat programmed, blower CFM verified, gas pressure measured, combustion analyzer reading taken, AC superheat/subcool checked. ESA electrical inspection scheduled. TSSA gas inspection on the furnace side. Commissioning report stays with the homeowner.

Brand Comparison

Lennox vs. Goodman vs. Fujitsu vs. Daikin

Honest take after 25+ years installing all of them. Every brand has a strong tier and a weak tier. The right pick depends on your budget, how long you plan to stay, and what your installer can actually service well in Toronto.

Brand	Strength	Warranty	Notes
Lennox	Best modulating gas furnaces (SLP99V), strong dealer network	10-yr parts, lifetime heat exchanger on premium models	Authorized dealer pricing matters, parts can be regional
Fujitsu	Efficient inverter ductless heat pumps for zoned comfort	Varies by system and registration	Best suited to ductless rooms, additions, and homes without central ductwork
Goodman	Strong price-to-performance across central AC and furnace systems	Varies by model and registration	A practical value option with current R-32 equipment available
Daikin	Premium inverter systems and compact side-discharge options	Varies by model and registration	A strong option when efficiency, sound, or tight side-yard clearance matters
Daikin Fit / Atmosphera	Compact inverter heat pumps, side-discharge designs	12-yr parts on registered units	Strong choice for tight Toronto side-yards

Megacity HVAC is an authorized Lennox dealer, but we install and service supported brands. The right brand for your home is the one your installer can support 12 years from now. Parts availability and dealer reputation matter more than badge prestige.

Common Questions

AC + Furnace Combo FAQs

How much does it cost to replace AC and furnace together in Toronto?

A combo replacement in Toronto runs $7,500 to $22,000 installed, depending on efficiency tier and equipment. Standard 92% AFUE furnace with 14 SEER2 AC starts around $7,500–$9,500. Mid-efficiency 96% AFUE with 16 SEER2 sits at $9,500–$12,500. High-efficiency variable-speed setups land between $12,500 and $16,000. Dual-fuel cold-climate heat pump plus backup furnace runs $14,000–$22,000.

Can I get rebates for both AC and furnace at the same time?

Megacity offers in-house rebates. Ask about them at your quote. We don't file government rebate paperwork for customers. Furnaces and air conditioners on their own no longer qualify for a standard government equipment rebate. Current government programs, and who submits each one, are listed at homerenovationsavings.ca. Toronto homeowners may be able to use a BetterHomesTO HELP loan to cover eligible work.

Should I replace AC and furnace at the same time or separately?

Bundle when one unit has failed and the other is over 10–12 years old, or when you are switching to a heat pump system. Replace separately when one unit is under 8 years old and running well. The bundle saves about $965–$1,800 in shared labour, permits, and inspections, but only if both units are actually near end-of-life.

How long does a combo HVAC install take?

A standard combo install takes 6–10 hours with a two-technician crew. We pull the old AC and furnace, run new line sets if required, install the new equipment, swap out the thermostat, commission both systems, and run the ESA electrical inspection. TSSA gas inspection happens shortly after. Most homes are heating and cooling the same day.

Does the AC need to match the furnace brand?

No, but matched systems can provide clearer warranty coverage, simpler diagnostics, and verified efficiency ratings. Mixing brands can work when blower airflow, refrigerant type, coil capacity, and control protocols are compatible. Proprietary communicating systems may require same-brand components to unlock their full variable-speed features.

What size AC and furnace do I need for a 2000 sq ft Toronto home?

A typical 2000 sq ft Toronto home needs roughly 60,000–80,000 BTU heating and 2.5–3 tons of cooling, but you should never size by square footage alone. We run a Manual J load calculation on every install. Insulation level, window count, ceiling height, and house orientation change the answer. Oversizing is the single most common mistake and causes short-cycling, humidity issues, and premature failure.
