My contractor arranged for A Plus Quality to install a new air conditioner, tankless water heater and programmable thermostat in my tiny Old Toronto row house in November. Quite a challenging job, especially the water heater installation, given the age of the house (around 150 years old) and cramped conditions. When the water heater initially didn't work as expected, they came back promptly to troubleshoot and then replaced the whole unit, making sure the equipment worked properly. They're easy to reach by phone, responsive to concerns and seem to take real pride in their work. Everyone I had contact with in the company from Lina (front desk), to Frank (sales) and Jack (technician) were a pleasure to deal with. I'm very pleased to have found this company for any future HVAC needs.
