Ellie, Marc, and I can't thank you enough for going out of your way and extending your day and enduring miserable traffic to repair Marc's AC unit. Your quality service is extraordinary and that is why we have had a relationship with J&K for over 30 years and always gladly refer those in need of AC and HVAC services to J&K. Last week Ellie posted her glowing remarks re J&K on Facebook and Yelp.
Thanks again.
Ellie, Marc, and Spence Schron
