We’ve been using Patterson Heating and Air 8 years. They are good about working us in when we need them(even when they are busy). The tech’s they send out are super nice, know what they are doing, and do quality work. They are fairly priced and they don’t try to sell you things you don’t need. For example: they kept our old A/C alive for two years then, when we had to replace it, gave us a great deal(we had several quotes), and did an top-notch install on the new unit.
