We found peter after calling around to many places to try and find someone to service a Rinnai (on demand water heater and also our boiler), a few other places we tried came out, looked at it and knid of scratched their heads then said sorry, must be too small to service the house. Well we knew that was incorrect so finally we found Peter and About Pure Air. He instantly dove right into the Rinnai to try and find the problem and did... turns out the whole system has been installed incorrectly and we were days away from losing heat completely! Since the initial work, we had various other problems all related to the poor install of the system as well as some upgrades that we wanted to do and all the work was done professionally and quickly. I can not say enough good things about Peter and his staff and I highly recommend them.
