"TLDR: safe, thorough, educational. 10/10 would call again. - My in-unit residential heater has been rattling and the filter light has been going off since I moved in (2 years). I've taken it apart (as much as I could) to do superficial cleanings, but to be safe I asked my landlord if I could find a Rinnai-certified technician to complete a professional servicing. I found Mazgan on Google and chose them due to their 4.7 rating. My landlord's initial concerns with outsourcing from the super was that companies tend to tack on hidden fees/charges. Mazgan did not do this. In advance of our appointment, Mazgan assured me that they were only booking me for a professional servicing appointment (which included opening up the unit, completing a comprehensive cleaning, and diagnostic), and that any issues found would not be addressed in that appointment but rather a 2nd appointment would be recommended if necessary. Thankfully, nothing was wrong with the unit (besides the fact that it has literally never been cleaned 🙃). Zaki, the technician, was extremely thorough. He cleaned the unit for nearly 2 hours, was very quiet and gave me a heads up when something would be noisy (which enabled me to work-from-home in peace), showed me photos of how clogged the vents were with dust/grime, and provided a lengthly and clear explanation of how the machine works and the importance of cleaning/how accidents can happen if not. They showed up when they said, charged what they said, and completed what they said. First things I did once Zaki left were to save Mazgan's number, purchase a carbon monoxide detector, and leave this review."

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"
