A1 installed both of my heater and air conditioner. Very professional staff, best quality of work and products, competitive price. With their annual maintenance plan, they send their staff to check on my heater and air conditioner twice a year. They have done great jobs! Highly recommended. If you need new heater and air conditioner, they are the best guy to go to in Oakville.

Excellent company. Come when promised, right on time, every time. Great value and piece of mind getting the furnace checked and cleaned annually. Several packages offer an excellent value to add all their services into one. Jose is our service tech and is one of the most friendly and talkative people I've ever met. I look forward to having him over to pick his brain about the furnace and AC. Will be a long time customer.

We are extremely happy with Appleby Systems. The installations and services they have provided over the years have been outstanding. This is our second HVAC purchase from Appleby Systems. Their prices are reasonable and the quality of workmanship is top notch. They arrive when they say they are going to, work efficiently and leave the area clean and tidy. I have no hesitation in recommending Appleby Systems to others.
