Ductless heads or central air in a GTA house, priced side by side

A central air conditioner sits outside the house, feeds an indoor coil, and pushes cooled air through ducts the building already has. It cools and nothing else. A ductless mini split hangs an indoor head on the wall of each room it serves, runs refrigerant lines back to a shared outdoor unit, and needs no ducts at all. Most ductless equipment sold in this market also runs in reverse and heats.

That gap in what the two appliances do explains why they are priced on different scales. Central air is one machine serving a whole floor plan through infrastructure that is already paid for. Ductless is one indoor unit per room, plus the outdoor unit those rooms share, plus a refrigerant run and a wall penetration for every head. The index keeps them as separate categories for the same reason. Of the 618 companies listed, 346 carry air conditioning and 250 carry ductless mini splits.

Megacity HVAC prices a standard single zone ductless system at $3,000 to $4,500, two zones at $6,000 to $9,000 and three zones at $8,000 to $12,000. Ontario HVAC Quotes puts each additional indoor head at $1,500 to $3,000, which is why the step from one head to three is not simple multiplication. The outdoor unit is shared. The heads are not.

On the cooling side the guides cluster tightly. Imperial Heating quotes $3,500 to $8,500 installed for a new air conditioner across all system types. Megacity HVAC quotes $3,500 to $6,500 for a standard 2 to 3 ton system at 16 SEER2. EcoFrost Heating quotes $3,200 to $5,500 for a standard central install. Three independent GTA guides landing that close to each other is unusual, and it makes the central air number the more dependable of the two for planning purposes.

Put the ranges side by side and the ordering at the top end is unambiguous. The most expensive standard air conditioner in Imperial Heating's range, $8,500, is only just above the bottom of Megacity HVAC's three zone ductless range of $8,000 to $12,000. Add a fourth head and Ontario HVAC Quotes adds another $1,500 to $3,000 on top of that.

With a single head, ductless is the cheaper purchase. Megacity HVAC's $3,000 to $4,500 for a standard single zone sits below Imperial Heating's $3,500 to $6,000 for a central air conditioner at 14 to 16 SEER. One room, one head, and the comparison favours ductless every time.

Two heads is where the two options meet. Megacity HVAC's $6,000 to $9,000 for a two zone system overlaps the upper half of the central air range, including Imperial Heating's $5,000 to $8,500 for a high efficiency system at 18 SEER and above. At three heads the overlap ends and ductless is simply the dearer choice.

The other thing that moves a ductless quote is the equipment tier. Megacity HVAC prices a cold climate single zone system at $5,000 to $9,000 against $3,000 to $4,500 for a standard single zone. A homeowner comparing a cold climate head against a central air conditioner is not comparing two cooling systems at all, because only one of them heats the room in February.

Central air pricing tracks floor area closely, because one machine has to carry the whole load. Imperial Heating maps Toronto pricing directly onto home size: $3,500 to $5,000 for an 800 to 1,200 sq ft home on 1.5 to 2 tons, $4,000 to $6,000 for 1,200 to 1,800 sq ft, $5,000 to $7,000 for 1,800 to 2,500 sq ft, and $6,000 to $8,500 for 2,500 to 3,500 sq ft and above.

Ductless pricing tracks room count instead. A 2,500 sq ft house with four rooms that need cooling is a four head project regardless of how the square footage is arranged, while the same house on a central system is one job sized to the whole envelope. That is why the comparison flips as houses get bigger and more subdivided, and why a small open plan space is the one situation where a single head genuinely undercuts everything else.

Efficiency tier stacks on top of both. Megacity HVAC prices central air at $3,500 to $4,500 for 14 SEER2, $4,000 to $5,500 for 16 SEER2 and $5,500 to $8,500 for 18 to 21 SEER2, a spread of roughly $2,000 that repays only over many Toronto summers of use.

The category counts describe a market weighted toward cooling. Air conditioning appears on 346 of the 618 records and ductless mini splits on 250. Heat pump installation appears on 221 and heat pump repair on 159. A company can sit in several categories at once, and 144 of the 618 carry both air conditioning and ductless mini splits on the same record, so a large share of the market quotes either approach.

Coverage is uneven by area rather than by service type. Willowdale holds 59 companies, Islington-City Centre holds 57 and Oakville holds 45, while Markham holds 24 and Scarborough Town Centre holds 22. A homeowner in a thinly covered area has fewer companies to compare, which matters more than which of the two systems they end up choosing.

The single largest variable in either quote is whether the house already has usable ducts. Megacity HVAC quotes $5,000 to $9,000 for a single zone cold climate system in a home that already has ductwork, against $9,000 to $14,000 where the home is larger or has no ducts at all. Imperial Heating quotes $5,000 to $12,000 for a central ducted air source heat pump, which is the same physical installation route a central air conditioner takes.

Existing ducts are also a source of hidden cost rather than a guaranteed saving. Imperial Heating prices ductwork repairs and sealing at $500 to $2,000 as an add on, and notes that adding cooling to a home that never had it costs $1,000 to $2,500 more than a straight replacement. A house with ducts sized decades ago for a furnace is not automatically ready for a cooling load, and the assessment of that is the part of the quote worth reading closely.

Ontario does not subsidise cooling on its own. Imperial Heating states that government rebates on standard air conditioners are not currently available. That is a flat zero on one side of this comparison and it does not vary by system size or contractor.

The other side has a number attached, but only for the right equipment. Ontario's Home Renovation Savings program pays up to $2,000 for a cold climate air source heat pump in a home currently heated by natural gas, and up to $7,500 in a home heated by electricity, oil, propane or wood. The amount is set per ton of rated heating capacity at 8.3C rather than by the price of the job, so the ceiling is not what a typical home receives. Both figures were read from the official programme page on 2026-08-03. Standard cooling focused mini splits are a different product and should not be assumed to qualify.

The electrical work is the item most often missing from an advertised price. Ontario HVAC Quotes prices a dedicated circuit and disconnect at $300 to $800 and a panel upgrade at $1,500 to $3,000 where the existing service cannot carry the load. On the ductless side, extra refrigerant line beyond the base run costs $50 to $100 per foot, and mounting hardware such as a concrete pad or a wall bracket costs $200 to $800.

Permits sit in both quotes and are small enough to be forgotten. Ontario HVAC Quotes prices permits and inspection at $100 to $400 on a ductless job. Megacity HVAC prices permits and ESA inspection at $150 to $350 on an air conditioner install, plus $100 to $250 for removing the old unit. Ontario HST is 13% on the installed price, which on a $10,000 three zone system is $1,300, so the first question on any quote is whether tax is inside the number or outside it.

The records here hold a category list, an area, a Google Maps rating, a review count, a phone number and, for 558 of the 618 companies, a website. They do not hold completed job counts, warranty terms, licence status or years in business, and no company in the index has an email address on record. Nothing in the data indicates which companies install ductless well and which install it badly.

The pricing on this site is collected from published contractor guides, not from invoices. Those guides are written by companies selling the work, and they describe a market rather than a house. The ranges are useful for spotting a quote that sits far outside them, and useless for predicting what a specific installer will charge for a specific floor plan. Three itemised written quotes remain the only way to convert a published range into a real number. Compare them against ductless mini split costs, air conditioning costs and heat pump installation costs before signing anything.
