Superior service from this company. I started with web research, just like you are doing now. Sent them an email on early Saturday morning, and was contacted promptly to arrange the consultation later in the day. Alec showed up on time, and 45 minutes later basic unit was recommended and selected for my needs. As luck would have it, they could install 2 days later, which was Monday. Kyle and David showed up 3 minutes early, and 6 hours later, my house has started to cool down. I teased Kyle, that while he arrived 3 minutes early, it was 24 years late for me. I should have done this a long time ago. As you research, you will find prices are comparable, so it is the service that makes a difference. This company provides that, in spades. The contract comes with first annual servicing for free. I will be using them for all my future needs. Rob A
