    Benefits of Quality Ductless AC Repairs

    We offer extended 10 years parts and labor, hassle free warranty.

    Diagnose Issues Quickly and Accurately

    Our technicians pinpoint faults in key ductless AC components like the inverter board, fan motor, condensate pump, or refrigerant lines. By accurately diagnosing error codes and performance issues, we restore your mini-split system without unnecessary part replacements or delays.

    Extend Lifespan of Indoor and Outdoor Units

    Timely repairs prevent strain on both the wall-mounted air handler and the outdoor condenser. Fixing refrigerant leaks, clogged drain lines, or failing capacitors early on also helps protect the compressor and keeps your ductless system running reliably for years.

    Restore Proper Zoning and Temperature Control

    When sensors, thermostats, or communication wires malfunction, ductless systems lose their zoning accuracy. Our professional repairs recalibrate controls and restore balanced airflow to ensure each room maintains the set temperature without hot or cold spots.

    Improve Energy Efficiency

    Low refrigerant levels, dirty blower wheels, or failing inverter boards force your mini-split to work harder. Addressing these issues allows the system to modulate properly, reduce short cycling, and maintain efficient operation with lower energy consumption.

    Eliminate Noise from Indoor Air Handlers and Outdoor Condensers

    Rattling panels, worn fan bearings, or loose mounting brackets can make ductless units noisy. Targeted repairs secure components and restore smooth fan operation to bring back the quiet performance mini-splits are known for.

    Enhance Indoor Air Quality

    Ductless air handlers rely on clean evaporator coils and washable filters to circulate fresh air. Repairing drainage issues and cleaning buildup prevents mold growth, reduces dust circulation, and supports healthier indoor air throughout your home.

    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.

    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.

    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 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.

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.

    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.

    Ductless AC Repair FAQs

    How do I know if my ductless AC needs repair?

    Common signs include weak cooling, unusual noise, water leaks, bad smell, or sudden increases in hydro bills.

    Most repairs are completed within 1–3 hours, depending on the issue and required parts.

    If your ductless AC isn’t turning on, the issue could be a tripped breaker, faulty thermostat, blown fuse, or capacitor failure. Check your thermostat settings and electrical panel first. If everything appears normal, professional diagnosis is needed to prevent further damage.

    What’s the reason behind the humming noise coming from the AC?

    A humming sound usually means the unit has power but the fan motor or capacitor may have failed. Continuing to run the system can cause compressor damage. Turn it off and schedule a repair right away.

    Yes, we provide urgent repair assistance for cases where cooling restoration is needed quickly.

    Warm airflow may result from low refrigerant, thermostat misconfiguration, dirty filters, or compressor issues. Make sure the system is set to “cool,” not “fan.” If the problem persists, let our technicians do an inspection.
