Seamus C with CCL Mechanical came to see an installation error (By another company) on my brand new Rinnai instant water heater. Seamus was on time and very professional, he diagnosed the problem quickly and went to work to fix the issue. Seamus offered several options for the fix and was up front with all the costs associated with the service. I'll highly recommend CCL Mechanical for your HVAC and Plumbing needs. They're licensed and provide high quality service.
