Arco is a great company. I have a Rheem Furnace and Air Conditioner from them. Unfortunately my AC quit right at the hottest part of the summer. It took a while - I think it was at least three days before someone could come out because they had to order a thermostat. My surge protector blew too. Then I lost power on the day they were coming to fix it. But Joe made it out late after the power came on and got the thermostat working. Surge protector finally arrived and was installed. Rob in the office was very nice and worked hard to get my problem resolved ASAP. And because I waited to get air conditioner fixed they gave me a discount on dryer vent cleaning. It worked out good. They have a great monthly service plan to cover maintenance and some service. They are reputable and stand behind the products they install.
