"Cardinal was fast on giving me a bid and compared to three other HVAC contractors that also gave bids they came in with the best offer. Installation went well and the installers were professional and even laid drop cloths to decrease any mess, as well as cleaning floors at the end of the job. The lead worker explained and demonstrated features of the system. I would use them again when needed."
