Annual furnace check. We have been customers of A-1 for over 25 yrs and during that time we have never found anything to complain about...reliable, friendly, efficient service. All technicians have been great! Dean was the last one to visit our home..he exemplifies what service is all about. 

Business response:

Thank you for sharing your experience with us. Without our loyal customers none of it would be possible! Looking forward to hearing from you for next seasonal service call.

Replaced furnace and air conditioning Based on a recommendation from a friend, I contacted A1 to replace an old and defective furnace. While discussing with their HVAC consultant I decided to replace also the noisy air conditioning and to add a humidifier. I opted for high efficiency Daikin and Aprilaire products and I am very satisfied with my decision. I especially enjoy the quietness of the furnace and the features of the ComfortNet thermostat. The installation was scheduled very quickly, the crew came on time and their w... read more

Daikon Furnace We are very pleased with our new furnace. Especially the fact it runs so quietly! Jeff Smith, A1's HVAC Consultant, was very informative and answered all of our questions completely. The installer was very knowledgeable, professional and he answered any questions we had at that time. Absolutely nothing left for us to clean up. We purchased a Daikon Air Conditioner last summer and are very pleased with it as well. The prompt service, excellent warranties and quality products A1 offers are wonderful. I've alread... read more

furnace and A/C new install Dispatch # 62796 - We had 2 different estimates from the top big box store competitor and a utility provider, but a realtor friend recommended A1 as "fair and reliable". So they became our 3rd estimate. I would never have contacted them if they were not recommended. They exceeded our expectations. From the estimate by Gord, which was transparent and thorough, and gave us the brand and units that were suitable to our needs, to the scheduling calls by Karen and Sue and installation by the two Mikes,... read more
