Marcus came out for a honest and thorough review of my current hvac system. After a honest appraisal of my needs he gave me an estimate for a new system. I countered that I had an estimate that was cheaper. He said they could match that price. They then had an independent contractor come out and perform a home efficiency test to evaluate my current situation. The installers were very prompt, thorough and polite installing the new Trane system in two days. Two nest thermostats, a new Honeywell zone board, a trane 97% efficiency furnace, a 18 seer trane a/c, 10 year parts and labor warranty, a 18 month zero percent finance loan and 11 k later we were in good shape. Then the independent contractor came back to retest our new system. We qualified for a $1500 rebate from pg&e! Very satisfied getting a premium system, with good people, solid warranty, rebate and great financing.

Thanks for everything.
