At Laird & Son Heating & Air Conditioning, we're proud to offer a complete range of HVAC and home comfort services designed to keep your family safe, comfortable, and worry-free all year long. Since 1948, we've been a family-owned and operated business that treats every customer like family—because that's what we've always been about. With four generations of the Laird family dedicated to this craft, we combine decades of hands-on experience with modern technology and a commitment to doing things the right way. From furnace and air conditioning service to heat pumps, boilers, and water heaters, our team handles it all. We specialize in both older Toronto homes and new construction projects, giving us the unique ability to work on everything from heritage properties to modern builds.

As we continue to serve neighborhoods throughout Toronto from our two convenient locations, more homeowners are choosing Laird & Son for reliable service they can count on. Our technicians are fully licensed, HRAI members, and TSSA registered. When they arrive at your door, they'll wear booties and use drop sheets to protect your home. Whether you're in Rosedale, East York, Forest Hill, or Leaside, we're here to help. We don't just fix your heating and cooling systems—we build lasting relationships with the families we serve.
