New Furnace Issue Dispatch #61756. I had A1 install a new furnace in July 2015 and decided it was now time to test it before the weather gets really cold. Set the thermostat to heat, furnace came on and brought the house up to temperature then shut-off. However on the next call for heat the furnace did not light and the LED indicator started to flash red. I called service, left a message and John promptly responded. He advised he was in Toronto on a call and it would be a few hours before he got to my house. He arrived withi... read more

New Furnace/AC/Humidifier #77169 I found A1 while doing a search online of local HVAC companies. My furnace was about 17 years old, mid-efficiency and was giving a few errors when heating up last winter. This summer my AC, which was also a little old, had trouble cooling down the house. This summer was so hot that it would run from morning until night non-stop and could barely hold the temperature. If it was extra humid or we had company, forget about it. And finally my humidifier didn't work at all, most likely because the ... read more

Annual maintenance ref# 60904 A1 have performed annual preventive maintenance on our air conditioner and furnace since they installed them about eight years ago. The technicians have always been prompt, friendly, knowledgeable and efficient every time. They were equally knowledgeable and efficient at the installation and were honest and candid when quoting for the installation. Have definitely never regretted selecting them . 

Business response:

Leak in Furnace Area Had a leak in furnace area related to humidifier and defective pump. Were at the house within 2 hours. Rigged a temporary fix so we could still use the air conditioning and came back first thing the next morning. Replaced both humidifier and pump very smoothly. John was a great technician. 

Business response:

John is a great technician...we are so glad that we were able to solve your problem!! Thanks for the review!

AC unit installation #59407 I recently have one of my AC replaced by A1 Air Conditioning and Heating. The technician detected a leak in the unit and could not find out the source of leakage. He recommended to replace the whole unit. The installers , Mike and Mike came the next day and they were very professional and understanding. I expressed my concern that they would need to cut open some area of my basement ceiling to replace the inside line. They even rechecked my indoor line even it was not part of their job. They ended... read more
