Just got a new HVAC installed by Cardinal. Absolutely fantastic experience. Jasmine and German are total go-getters, with the best customer service and follow up. They were the lowest estimate we received after consulting 3 other companies and they even threw in a couple of extras on top of that. We have had our new system for a week now, I can't believe how quiet it is - Trane 15 seer 4 ton unit. I feel like I really lucked out going with this company, they treated me extremely well which is so rare nowadays. I'll be referring Cardinal to everyone possible.
