We have used Pro-Tech Air Conditioning and Heating numerous times and overall they have been great to work with! They are very reliable and super-professional. Their techs are friendly and punctual. And, they communicate very well with us. The last time they were here they separated out some gas lines for us for a special project. Pro-Tech Air Conditioning and Heating is a good company and we would highly recommend them to everyone! They are very good at what they do!
