Sierra Air Limited

Alex and his team has been servicing my heating and cooling equipment for 6 years including the installation of a new furnace. They keep their appointments and do the job efficiently at a reasonable cost. I had no problem in getting service under warranty. I am a completely satisfied customer and you will be too. Give them a try!

I contacted Sierra to fix a ductless a/c unit that had stopped properly cooling my apartment. Alex was great! He diagnosed the problem easily (leaking valve) and then came back to fix the unit. He told me it would cost about $500, but when all was said and done it was actually $100 less. Before coming in to fix the unit he also helped me with some troubleshooting over the phone to see if maybe I could fix it myself and save some money. Honestly, Alex was friendly and great to work with – I would highly recommend going with Sierra.

I have used Sierra Air before in my other home. We are now in a new house and needed the furnace, air conditioner inspected, as well as the hooking up of a new gas bbq. In addition a new programmable thermostat was installed, new filter for furnace, as well as a new filter for humidifier. All the work was done on schedule, neatly done, and everything works beautifully. The company has demonstrated a marvellous work ethic, and obviously takes a great deal of pride in their work. I will continue to use Sierra Air for future needs. This is indeed a company I will continue to recommend without hesitation

We needed to replace our home's old furnace and air conditioning systems with better and more efficient ones. Alex who owns Sierra Air Limited provided us with what we needed at a very good price. His exceptional communication and outstanding service amazed us. Alex has great knowledge and expertise, he was very patient with us from the beginning, through the installation (they even covered the area of the house where they walked) till the end. He did a great job!!! We have already recommended Alex (Sierra Air Limited) to our relatives and friends, and will not hesitate to recommend it to everybody.

I dealt with a very professional and friendly technician named Alex. I felt very assured in having received and honest estimate. The work was done in a timely fashion. Central air now works beautifully. Very satisfied!

Sierra Air Mechanical installed a new HVAC unit at my condo, with a specialty thermostat. The installation was quick and easy! Alex was kind and resourceful. He overcame all of the challenges of our specific installation.

Suddenly my central air condition broke down while outside had hot alert continues in summer time. I was immediately looking for its’ service. Apparently my friend referred to Mr. Alex at ‘Sierra Air Mechanical’ then made a service call and immediate inspection done by Alex. And the following day I had an excellent service and having my air conditioner repaired by Alex before my expectation time. The repairs were made just before my expectation time and within my budget. It seems like my air conditioner is running much better now than it had in years ago. … thanks a million to Alex and Sierra Air Mechanical!

Alex from Sierra air was a hero - several companies messed around with our AC, charged us, and we were no further ahead. Alex was diligent, ingenious and found us a solution. Highly, highly recommend!!

We woke up to find an alarming amount of water in our laundry room, after running the A/C for one of the few times this summer. As first time home owners, we were unsure what to do, and since we didn't want to make a bad situation worse...we thought to turn to the experts!

Alex was not only reassuring, but extremely proactive in giving us some helpful tips to try at home so we could narrow down the issue. He followed up with us and planned a quick visit to our home. He quickly identified our small issue of a bit of drain plugging, and fixed it within seconds.

He was so easy to work with, and immediately put us at ease about how to prevent future issues with our furnace, along with education on regular maintenance. Thank you Alex!

Great customer service - delivery to the door. Alex was excellent and went to the trouble of calling before delivery. Ordering and payment on line was easy, practical and effortless.
