"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."
