Peri did excellent work, service was prompt and on spec. He even worked extra hard to solve an unforeseen difficulty. Highly recommend.

We had a zone of our ac stop blowing cool air. Thought it might be the compressor failing or something similar. Peri and Ody spent quite a bit of time and were able to diagnose the problem and that some parts needed to be replaced that had failed and were keeping the freon from being able to reach where it needed to so as to get the air cool. They did great work, always replied promptly and communicated well!

Proto came the same day I called and got our AC back up and running. Great service and a fair price

I have used this company four or five times over the last year or two. Honest, reliable, and professional. I own a business in an adjacent town and have had bad service with heating companies for a few years. Many recently. I should have used them for my business needs. I chose Proto because they are a small company competing against the monopoly. They are the best.Old school values. They are not part of a business that was bought out by a private equity company, like most. Take advantage of a small company and service while it still exists.

Proto Home Service found my HVAC coil extremely dirty and clogged with dust and buildup. They showed me exactly what was going on and took the time to address the problem properly. Great service and very professional!
