About Laird & Son Heating & Air Conditioning
Very few trade businesses in Toronto can say they were around before the Gardiner Expressway. Laird & Son started in 1948, with its first location at 121 Laird Drive in Leaside, and its website says the company is now run by the fourth generation of the family. Neil Laird is listed as president, and a Noah Laird appears among the technicians named in reviews. The Scarborough branch on Dynamic Drive is the one ranked here, and a second Laird & Son profile covers Leaside and East York.
A company that old has seen every kind of Toronto heating system, and it shows in the service list. There are furnaces and boilers, heat pumps, central and ductless air conditioning, tank and tankless water heaters, and indoor air quality products. It also still handles oil-to-gas conversions with tank removal and even delivers heating oil, which is rare now and handy for the houses in the east end that still burn it. The site says about 90 percent of its work comes from existing customers and referrals.
Reviews on the Scarborough profile back up that loyalty. One homeowner had a mini-split maintained five years after Laird & Son installed it and praised the same careful approach. Another called about a failed hot water tank on a fully booked day, and the scheduler still found an after-hours slot. Someone else describes a heating problem several other companies could not solve, which the Laird team diagnosed and fixed with a new install. Names like Greg, Mack, Anthony and Arthur come up repeatedly.
Posted hours are 8 AM to 8 PM, seven days a week. That covers most needs, though it is not advertised as round-the-clock service, so ask how overnight emergencies are handled. The company is TSSA registered, offers financing and gives free estimates on new equipment.
Who it suits: homeowners in Scarborough, East York, Leaside and the wider east side who want a firm with decades of history and a strong referral base. It is also one of the few choices for oil-heated homes that need both delivery and a conversion plan. Who it suits less well: someone after the lowest possible price, since established family firms rarely compete on that alone.
Before booking, ask about the maintenance plan terms, confirm whether the quote includes permits and gas line work, and check what the labour warranty covers.
