I can highly recommend Marv and his team at Service Tech. I always feel like I get a straight story with no upsells. They fixed an A/C issue on a holiday weekend free of charge. Great guys.

Quick response, friendly, affordable, excellent service. Marvin came out within the hour and fixed our furnace when it was well below zero. Service Tech came out within an hour and helped me to resolve the issue. I am a customer of Service Tech for life!
