What Our Customers Say

Amit was a pleasure to work with, and his install team was super respectful, communicated well, and arrived on time. The install is very clean and professionally done. Prices are fair and comparible, but you can’t put a price on service/support, this aspect was met and I am happy I went with them for service. My decision was based on google rating feedback such as this. I will be doing business with them for my A/C in the future.

StoiK NA

Our family has been a client of Ideal Heating for almost 5 yrs. They did an excellent job building and designing our HVAC system and have provided annual maintenance since. We highly recommend Amit and his team.

Rodrigo Domingues

Amit came to service my elderly mother’s furnace today it had been functioning on and off for a while. He was extremely responsive and diagnosed the issue and explained everything patiently. He also ensured my mother had a safe and working furnace before he left. I would highly recommend him.

Rose Moretti

Amit is excellent – I highly recommend.

Jordan Glick

Polite, kind and efficient! Excellent service!

Ashley Myerson

Highly recommended! I was in need of replacing a 24-year-old AC unit with a heat pump that qualifies for the Enbridge rebate. Amit was very knowledgeable and let me know exactly what needed to be done. His crew (KJ and Nino) did an excellent job, installing the heat pump in about 6 hours. They also took care of some issues I had with floor registers not fitting. I would totally reach out to them again if I need anything HVAC-related.
