Sierra Air Limited

About 3 weeks ago, we discovered our natural gas line furnace wasn’t producing any heat. We went through our regular energy provider and a few service technicians to resolve the issue, but all diagnosed the same issue without a permanent solution. Eventually our energy company identified the need to hire a licensed gas technician to do repairs on our gas line furnace. After some attempts to get a hold of the right company, I was instinctively led to contact Sierra Air Mechanical.

Upon calling them, I felt an immediate confidence that this company was competent to resolve our issue stemmed from a gas meter changed enforced on our residence by the Federal Electricity ACT Section 12. Thanks to the creative and compete efforts of Alex and Dan, licensed gas technicians, we were able to see a very complicated problem resolved in approximately 3 hour effort, in addition to test and inspection efforts.

Not only was the installation done timely, it was done right the first time with reasonable cost and with care, understanding the efforts needed to be as seamless as possible, to give us heat and minimize any additional renovation and repair work required inside the home. We are so grateful for the friendly, competent and creative service provided, to restore heat to our home.

I heard about Review Sierra Air Limited from a friend. Called them last month for repairing my air conditioner and they were did the job really well. They were punctual and fixed the problem without taking long. I will highly recommend this company to anyone for air conditioner servicing because they're highly professional and well trained.

We needed a new air conditioner and to have it relocated to the side of the house instead of the back. Alex was professional and detailed and took the time to carefully explain how the work would be done. Over the next few days, he promptly responded to all my inquiries.
He did a great job moving the unit and sealing up where the old one was. You can tell he takes pride in his work as he ensured everything was done right. He was respectful and clean. We are happy with his work and the air conditioner. I would highly recommend him.

Hello,
I was having trouble with my furnace earlier this week.
I came across Sierra Air which was referred to by a friend of mine.
When Alex who owns Sierra came to visit, I was very surprised at how Professional and polite he was from the beginning. HE was able to come in and identify the problem. He even went out of his way to see if there were any other issues with my gas piping and noticed there was some carbon monoxide traces in the basement. He got to work right away and I must say did an excellent job. Very clean and handy work. Replaced my furnace in almost no time at all and the pricing was more than reasonable for the kind of service that I received. very honest and showed me the parts he replaced and how they work. I highly recommend this company and the great services they provide. 5 stars for me and hope you have the same great experience I did! thank god I got some heat just in time for winter!! Now the wife is happy :)

I was searching online to purchase furnace filters and happened to come across Sierra Air Mechanical in Mississauga. I decided to give them a call and spoke with Alex. I found him very helpful, honest (which doesn't seem to exist in the business world anymore), and very knowledgeable about the products. He recommended the products I needed, not what's more profitable to him (another rare quality). He delivered the items in person on the same day and installed for me without charging for the service. Where can you find such service nowadays?

I was quite impressed with his service, so when my sister needed to replace her Air Conditioner I called Alex for pricing. He responded right away and gave me written quotes via email while other companies insisted on coming to my house before giving me any estimate (sales tactic). Again, when I asked him which unit would be sufficient for the house, he recommended what my sister needed at a competitive price. No matter how many times I called in a day, Alex always answered and returned my calls promptly. To top it off, he was able to install it the next day, which is much appreciated in this heat wave. I would definitely recommend Alex to friends and family members.

Our air conditioner had been malfunctioning since we moved into our home last year. The copper piping kept icing up and the vents were only blowing lukewarm air. This seemed strange because it was a brand new AC unit. We had 3-4 different repair companies come by and each gave a different diagnosis of the problem. None of them were able to fix it. They all recommended replacing the coils, which would cost at least $600.
With my wife pregnant, there was no way we could sweat through another summer. On my dad's recommendation we tried Sierra Air. Despite being based in Mississauga, Alex drove all the way to the edge of north Toronto to our place. Within minutes he diagnosed the problem, which turned out to be leaks in the copper piping caused by poor welding. Alex fixed the problem that same day and our AC has been working perfectly ever since.
This is a highly professional company that I would recommend to anyone if you want a proper diagnosis of your HVAC problem and a speedy repair.

We got a new furnace last year in November and prior to that a new A/C unit.
Technician: Alex Montesdeoca at Sierra Air Mechanical has done an excellent job both times.
Alex has exceeded my expectations and has gone above and beyond.
AI am very happy with Alex and Sierra and I do recommend them to all potential customers.
You will not be disappointed.

My 36 year old furnace died on a very cold day in January. Expecting such an eventuality, I had already researched HVAC companies online and arrived at Sierra Air and am simply elated that I did!

Alex and his crew arrived punctually and very professionally and efficiently proceeded to replace my furnace and the workmanship was superb. He was an absolute pleasure to deal with and was very thorough and patient with all my questions. And he was absolutely right about the product and how different it would be from my previous furnace! I love my new furnace and will use Sierra Air for all my HVAC needs in the future.

They are expedient, very trust worthy, and very thorough with their service visit. Nice to see honesty in a business usually lacking a little integrity. Highly recommend this company for heating and ac sevice.

This company was referred by a friend and they certainly did not disappoint me. They were punctual, clean, professional and efficient. They assisted with rebate paperwork and went over and above. I would recommend them for your next heating and air conditioning job!
