Central Air - Paula from Etobicoke 

Alex and his crew were fantastic. The quality of service was beyond. We had a very difficult installation in the attic of our house and they rose to the challenge. We also have a boiler hot water system in our house for heating and we will be using them for checkups and any furnace or ac repairs required in the winter. We would highly recommend this company for any of your cooling or heating. 

Commercial A/C Installation - Victoria from Etobicoke

I met with several companies and felt comfortable with Alex's level of expertise and helpful demeanor immediately. His customer service and product knowledge were invaluable! I would highly recommend Sierra for both residential and commercial needs. They are efficient, cost competitive, and offer quality service and value. Thanks Alex!!!

Furnace Motor - Mauricio from Mississauga 

Alex has been my go-to guy for AC and heating issues. This time around, my furnace died with -8C weather and hours before I was travelling south! Called Alex and he was kind enough to accommodate the urgency of my issue. He diagnosed the problem in no-time (seized furnace motor) and solved the problem fast and affordably. Alex' honesty and skills are above the norm. I highly, highly recommend him. ‚Äč

Furnace and A/C Installation - Alex from Mississauga 

Alex from Sierra Air was very professional. He completed the work with a great focus on fit and finish. After completion he patiently explained to me what he did which helped me understand the work done in my home and assured my confidence in his work. Also, he was available for any follow up phone calls I had. I would do work with Sierra Air again.

Installed Heat Pump - Lorraine from Barrie

Sierra Air installed a heat pump in my condo and did a great job, I am very pleased with their work. They worked all day, cleaned up after (leaving my place spotless) and the heat pump works amazingly! I would definitely recommend them to someone else.
