Excellent experience on a number of occasions over a few years for maintenance and repair of both heating and cooling systems. Highly recommended.

Received quotes from multiple contractors to replace the furnace and a/c in my condo. Adrian from Demarco was able to set me up with a quality system at a good price. The installers arrived when I was told they would and were professional and clean. Having worked in the trades myself for nearly 20 years, I think I’m qualified to say that the final install is neat, clean and performs great. Taking pride in their work shows. I would definitely work with this company again and recommend to anybody.

Called them recently for a gas leak issue. Adrian sent over a technician within 2 hours, the guy was friendly and skilled. He quicky checked and ruled out the potential causes which were more serious anf finally figured out the issue. Fixed everything within an hour. Great service, quick response.

We had a gas leak issue and Adrian responded quickly to ensure we were back up and running asap -- we had a technician within a few hours. Alex -- our technician -- was extremely professional & knowledgeable; he ensured we understood exactly the required work and we never felt like there was any push on us for unnecessary work. He checked places our utility provider missed and ensured our place was gas tight. Extremely happy with the service, and while i hope we dont even have another leak issue, we'll be sure to use DeMarco in the future for any of our HVAC maintenance.

Fantastic from start to finish. Adrian is a consummate professional whose pride in his work, craftsmanship, and attention to detail shows. Cannot recommend more highly. Give him a call - you won't be disappointed.

Adrian was very knowledgable and provided usa with excellent advice on furnace replacement and installation of a tankless water heater. The work was done on time and for the price quoted. Highly recommend his company.

I contacted Adrian when we were advised that we had a gas leak in our home. He was quick to reply, extremely helpful in explaining our options, personable, COVID-safe, and even brought boot covers so as to not track mud into our home! He was in and out in a flash and we would definitely use his services again!

I called DeMarco Mechanical at 8 PM after discovering that a contractor working on my neighbour's house had damaged my BBQ gas line. Adrian reviewed my photos right away and sent Alex out the next day to do a full inspection. We really appreciated the quick response! Alex was thorough, professional, and happy to answer all our questions regarding natural gas safety.

We made an emergency phone call to Adrian for a minor gas leak repair. He came quickly and rectified the matter. Very professional following COVID guidelines and answered any questions we had regarding the process. Thank you for your timely service! Very much appreciated. Would definitely recommend.

this guy is great... his prices are reasonable.. hes open to give advice... he doesnt leave a job unfinished... he is professional... installed a gas line for me in my condo unit... came out great and when the line didnt connect to the bbq because of mismatched size he was here within 2 hrs. safe to say that i was happy... happy to refer him to family and friends..

Our 20+ year old Air Conditioner stopped working unexpectedly , Adrian was able to come first thing the next morning and run tests. He gave us repair and replacement options, and based on the age we replaced the entire system. He did an amazing job at a great price, I highly recommend DeMarco Mechanical for any of your HVAC needs.

Had a has gas leak during the Covid-19 pandemic. Called up DeMarco and they were able to service the next day. Adrian showed up on time, very professional, with appropriate PPE. Great service, helped walk me through everything that they were doing while solving the issue. If I'd know there was a specialist like this out there I wouldn't have been so stressed out about having a gas leak found in my house.

Adrian was very professional and knowledgeable. He was easy to communicate with and was reliable and responsive. He showed up on time and finished the job within the expected timeframe. Price was fair. Highly recommended for any gas related services.
