We had Perfect Comfort System install a new heater, payne air conditioner and duct work about 5 years back. We have been very happy with the system, but what really makes this company stand out is the follow up service. We have had a few questions over the years and always received friendly helpful answers, even a couple house calls. A couple weeks ago the air conditioner unit stopped cooling and we were in a panic, we called spoke to the company owner Corbin, he came out that day and had us up and running in no time and was very very fair and friendly. It is nice to see that there are still companies that believe in great customer service. D&D Pomona
