Mario from GC Reliable performed the annual maintenance and diagnostic check on my boiler. He was very knowledgeable and explained everything clearly at each stage of the process. He also identified a faulty aquastat control box as the reason the circulation pump wasn’t working. I highly recommend Mario and GC Reliable with complete confidence. Thank you,

First off, excellent service and experience. Mr. Ivan Garcia was great! Solved the problem quickly and talked me through the boiler, answered my many questions, and pointed out things I could to pay attention to to better maintain my boiler and reduce cost. Recently moved into a house. Hot water stopped. No idea with oil boilers but excited to DIY. Had no idea what we were doing and made a mess with fuel spillage. Decided to call a professional. Contacted a few local providers but either required oil purchase or couldn’t service (charged me despite stating on arrival that it’s not their expertise - apparently it’s their robot phone agent’s fault…). Called R.C. Reliable. Great first impression, was greeted by a friendly gentleman. He asked questions, talked me through the expectations, dispatch time, service rates, and congratulate me on the new house. Very professional and transparent. The rest is history, Mr. Garcia arrived promptly and took care of the problem. Now we know that we have a reliable provider in the neighborhood that we can trust. Would highly recommend without reservation.
