I had called for service and got prompt acknowledgment from a service technician with a diagnosis and repair estimate within 30 minutes of appointment. A follow up call by Tim was professional and exceptional. Great folks to do business.

As with all skilled trades, you find a good one and you stay loyal. Annison-Bitter falls in that category. Called at 10:30 to schedule service (no heat), they set my window same day for 11:00-2:00, and provided a 20 minute call ahead. Tim showed up on time, very professional and friendly throughout. He was extremely experienced and knew how to quickly isolate the problem and solve it. Definitely recommend!

I received fast, A+ service!!
I called several local companies to help me install my new Nest thermostat, and went with Annison-Bitter since they were BY FAR the most knowledgeable about the device. Within 24 hours of calling, Tim and Caleb, the technicians, were able to come out to my house. Both were very friendly and great to work with. Tim is a fellow techie and had it installed in no time. He knew everything about the Nest, and was able to give me an excellent tutorial.
Based on my experience, I would highly recommend this company!

So we got a new Hvac unit for the house installed today. Holden Bitter and his crew of 3 showed up at the time they said they would. The crew was professional courteous and hard working. They didn't make a mess and if they did it was cleaned before I saw it. The instructions were easy to understand and they stayed to make sure I understood everything I could about the unit and it operations. Classy guys, great customer service and quality work. Highly recommend these guys.
