I had an absolutely outstanding experience with Husky. Earlier this month, on the hottest weekend of the year (humidex of 45), a terrible coincidence occurred when our AC unit stopped working on Saturday of the Canada Day weekend.
That night, by pure chance, we saw a social media recommendation for Husky, saying to give them a try. We called them Saturday night at 10 pm and someone picked up (they have 24/7 service), and they said they could send someone over the following morning (Sunday, July 1 - Canada Day). We couldn't believe our luck.
The technician, Dave, who came quickly evaluated the issue (broken capacitor) and replaced it on the spot. AC worked right away. Total cost was under $300 for part and labour, which given it was provided on a holiday on short notice, was more than a fair price.
Overall, I would highly recommend Husky for HVAC purposes. They were friendly, responsive and quick. Really outstanding.
