Transparent pricing, same day response and service. Brenden was kind and polite and answered all my questions. Cody delivered the part to my place while Brenden was here to ensure i wasn't without heat for the nightand they even offered temp heating solutions should i have had to gobe without my furnace for the evening. Will definitely be my hvac service provider of choice going forward.

Our furnace went out and the same day Brendan from CGS was at our place to fix the issue. He had it up and running in no time. Highly recommend their services!

Have used CGS to replace the central furnace and the water heater with a tankless one. In both cases they were helpful in choosing the units as well as reaching challenges faced with the previous units. Good services and value and wanting to ensure they make me a satisfied customer.
