Terrific service

The service professional was determined to solve an elusive problem with our heating system. He persevered, coming back for 3 days until it was repaired!

Good service

I called CCL on Monday, they scheduled technician for between 1-4pm Wed. Seamus called at 1:10pm Wed and completed a repair by 3:30. He explained the problem, prepared a quote & stayed to balance the system after the repair. Well done.

CCL Mechanical Consistently Great

I believe you get what you pay for. CCL is not the cheapest but they are thorough, honest, and very good. Having my hot water and heat functional throughout the winter is worth paying for. I use their maintenance plan and feel good all year that if anything breaks it's covered and/or discounted for repairs.

True expertise

My steam heating system was always a little noisy since I bought the house 6 years ago. More recently the banging in the pipes got so bad that I called in the installer of the most recent boiler. He claimed to specialize in steam heating, but couldn't solve the problem. Then I brought in CCL Mechanical. Jared accessed the system and told me the near-boiler piping was incorrect, and would have to be re-done to eliminate the problem. I hired them to do so, and the system is so quiet now you would think it isn't even on (other than the air vents hissing a little). Jared is a steam heating expert, which is just what I needed.

Paul's the best!

2nd time working with Paul and he's really exceptional. Super courteous, professional, gets the job done, and he was great interacting with our kids who were fascinated by the toilet getting taken apart.

CCL Mechanical - Excellent As Always

My experiences with CCL have always been first-rate, and my latest AC service with Ryan was more of the same. I feel he treated my equipment like it was his own. Excellent communication, personable, on-time, answered my every question. Couldn't be more satisfied. Highly recommended.

Quick fix

When we found water leaking from our outside spigot, you found a spot for us in your calendar the next day and had all the ancient fixtures replaced quickly and cheerfully.
