I would just like to say how it’s been a pleasure to work with Al and his son Richard of Mueller Mechanical. I’m very happy and relieved to have finally found a reliable and professional HVAC company to handle my custom homes, and renovation projects!

Al Mueller is a highly skilled and knowledgeable person offering professional service. Recently we had two tankless hot water systems installed. The installation went perfectly. Al and his staff are clean, courteous and were a pleasure to have in our plant. Will I call Al Mueller in the future for additional jobs? – 100% yes. I highly recommend him to anyone looking for a job well done.

Since we moved into our unit on Timberlea Blvd, Mississauga, 7 years ago, Al Mueller has been looking after our heating/cooling system. He does our annual inspection per our lease. As well he replaced our roof top heating unit last year. I would recommend Al’s services to anybody.

I hired Al Mueller of Mueller Mechanical Ltd. to help me install a new machine earlier this year. He was very fast getting me a quote and completed the job on time and on budget. I would hire Al again.

From the initial quote to the the completion of installation, service was professional and seamless. Richard clearly explained the different products available and what we needed and why. Richard and Jaimie arrived on time for the installation and the work was done with no mess left behind. Richard explained the new thermostat and the new unit once everything was done. All in all great service - we highly recommend Richard and his team.

Have used Richard to install 4 furnaces, hot water tanks and air conditioning units at various properties this last year. His pricing has always been extremely competitive, his crews have always taken care to protect the Flooring etc. At the end of the work you would never know they had been there. Extremely pleased with the work and quality of the installs. Highly recommend. True professionals
