Tamer was great, changed our entire HVAC unit, which now works perfectly fine. Very professional service and very knowledgeable, would highly recommend them for HVAC services.
We had an air conditioner malfunction over a long weekend and Tamer was kind enough to come fix it the next day! It's been running great ever since!Update: Our furnace also ended up acting up, and we got the same great service fixing that.
Very knowledgeable technician, knows what need to resolved the issue, quick response and we'll in time as committed.
Excellent as always! On time. Extremely thorough. Double checked all areas of concern and made the appropriate repairs. You couldn't ask for a better HVAC provider.
Had an issue with my old AC. Tamer visited, provided the right suggestions and installed in a day. Great professional service and strongly recommended.

Tamer is the friendliest and easiest person to deal with. He rearranged his schedule to accommodate mine. I recommend Tamas mechanical and will continue using for all my needs
Needed help getting our air conditioner working again, great service. Tamer knows his stuff, was thorough, clean and explained everything he was doing as he went along.
I've been having issues with poor airflow at a number of my vents in addition to some freezing in my furnace room in my home in Mississauga. I found Tamas Mechanical online. They have great reviews, and after speaking with Tamer and having him complete his diagnostic, I see why. Tamer was professional, patient, and fair throughout my engagement with him.Tamer quickly identified the issue and tweaked some settings to resolve it. I will be going back to Tamer for all my HVAC needs going forward!
Overall I had an excellent experience with Tamer installing a smart thermostat in my home. He was very polite, organized, knowledgeable and very easy to work with throughout the process. I have already booked him in to service the furnace for next season. I would highly recommend hiring him for any work needed.
The gentleman was very knowledgeable, experienced and extremely helpful. He was fast in repairing my gas leaking pipe. I plan to use him again in the future. His company deals with gas leaks, furnace maintenance, duct cleaning and air conditioning maintenance. I'm a very satisfied customer.
Tamer was excellent in diagnosing and fixing a complicated furnace issue we had. This was not my first time using Tamer and it won’t be my last. He is our go to guy for HVAC. Very professional, conscientious and good at what he does. Would highly recommend.
I hired Tamas Mechanical Inc., for furnace and duct cleaning. Tamer’s team, Mahdi and Blessing, did a great job. Mahdi was careful and efficient with his work. I also appreciated that they were respectful of us and cleaned up after the service. Tamer was very responsive when I was inquiring and booking. Had a smooth and easy experience with them. I highly recommend these guys and would hire them again in the future.
Tamer did the job perfectly, he came ontime and his dedication to do task properly was obvious. Highly recommended
Had a great experience with this company. I was having a BBQ at my new house in a couple of days and needed an HVAC company to install a new natural gas line for my BBQ. I put a request in Homwstars and got a call from Tamas very quickly and arranged for a technician to arrive the next day and provided a quote over the phone based on some photos and measurements. Tamer was the technician and took about half a day to install the new line which worked perfectly. One small issue was that my fireplace pilot went out during the installatio and I couldn't relight it. But Tamer came back to do a manual light at no extra charge. Very happy with the service, price and friendliness of staff.
Tamer was a helpful guy. Helped fix my problem within a couple of hours. Would recommend him for any hvac issues.
I was struck by how honest he was. Didn’t charge me for a small task months ago and quickly resolved an issue today. Good workmanship and great value. I’m happy to rely on Tamas for my HVAC needs.
Tamer is great and makes sure all your equipment is in running order. Way better deal than something like Reliance. Here is the Bryant AC unit that he installed for us.
Tamas Mechanical provided great service. Was able to get a quote over the phone with a few pictures and have them completed 2 days later. Amazing work!
We needed repair work done on our HVAC/furnace. He was quick to respond, and quick to get to the repair. The price was very reasonable for great and honest work. Tamer was exceptionally knowledgeable and will not give empty promises. He was detailed and transparent in showing and explaining what the problem is, what he would recommend, and also allowed me the option to choose which route I wanted to take to truly fix the problem. He does not give you the run-around and works as quickly as possible without compromising quality. We felt like we were truly taken cared of. On top of that, the repair was flawless! We highly recommend Tamas Mechanical, and will gladly use his service again (should we need future repairs/ installations).
Tamer was very responsive and took time to understand the air conditioning issues and set very realistic expectations based on facts. Scheduling a visit was quick and easy, he arrived on time and did what was needed quickly while also being patient and took time to answer all questions and explained the details in relation to possible replacement of our old A/C and Furnace without trying to oversell us on anything. We would definitely recommend Tamas to everyone if you want someone who is clearly hardworking, wants to earn an honest living and win customers over the right way! Thank you Tamer and really appreciate your time and effort, you will definitely be our go to person for any heating/cooling issues.
I received excellent advice from Tamer regarding what power/BTU furnace I should choose. Prior to calling Tamas Mechanical, I had called several other companies, where I was getting conflicting and not clear advice on what BTU size I should choose. However, Tamer was clear on what BTU size I should choose and fair in the pricing. I was able to get advice on a Monday morning and order the unit by Tuesday and fortunately they accommodated me and had it installed two days later! The furnace is currently working well and keeping us warm and I also have a new humidifier April air 500 series that was also recommended and seems to be making the air in our house better. I will now be getting my ducts cleaned by Thomas mechanical and look forward to this service from them. I highly recommend this company.
We had Tamas come out due to a leak. He was professionally, timely and super friendly again this time. We are very satisfied with the work he did.Tamas is a great guy. Very friendly and informative. He installed a tankless water heater for us which has been working great. Also gave us a great price compared to what we were being quoted by others. Will definetly use his services in the future.
Tamer was quick to come diagnose our furnace and very knowledgeable on what the problem was. He took the time to answer our questions and listened to our concerns. He stayed in contact and updated us about when the part was going to be available and it was a quick turn around. He was very accessible and efficient. We would definitely recommend and use tamer again!
Tamas Mechanical were a pleasure to deal with. They replied promptly to my request, showed up within 12 hours and diagnosed the problem. Although the repair was beyond their scope, they were honest and upfront and recommended another company. I would use in the future if the need arises and recommend to others.
Tamer Sayer was the technician who came to service my furnace. I should preface my furnace is 14 years old and two other companies failed to fix the issue. Tamer spent over two hours diagnosing the issue and fixing it. Three weeks later furnace is still running like new. Al very grateful 🙏

How do I choose the right HVAC contractor in Oakville?
Compare multiple quotes, verify that the contractor is licensed, and ask about warranties before making a decision. A reputable HVAC company should provide transparent pricing and clear recommendations.
Why is it important to hire a licensed HVAC contractor?
Licensed technicians are trained to install and repair HVAC systems safely and according to industry standards. Proper installation also helps protect manufacturer warranties and system performance.
Should I ask about HVAC warranties?
Yes. Always ask about both equipment warranties and workmanship warranties so you understand what is covered after the installation or repair is completed.
Do I need duct cleaning?
Duct cleaning may be beneficial if you have excessive dust, recent renovations, or indoor air quality concerns. However, many homes can maintain good airflow with regular filter changes and HVAC maintenance.
How often should HVAC systems be serviced?
Most heating and cooling systems should be professionally serviced at least once a year. Regular maintenance helps improve efficiency and reduce the risk of breakdowns.
Should I repair or replace my HVAC system?
If the system is relatively new and the repair is minor, repairing it is often the better option. Older systems with frequent problems may be better candidates for replacement.
