Mhc Home Comfort

My Rinnai was installed by the previous homeowner who used MHC. We discovered that the installation was done incorrectly after a year since moving in (rusted water dripping out of the unit). We called Rinnai who referred us to someone who could look at it for us and diagnose the problem. Once it was diagnosed, we contacted MHC who had originally installed the unit and asked them to come fix it. I was surprised that they were so willing to come out (they came within 3 business days) and fixed the problem right away. The technician was very friendly and fixed everything according to the Rinnai technician's specifications. Good experience overall but wish it was installed properly from the beginning!
