“Dav is an consummate professional. We used his services to design a new duct work flow for our house when our 20-year-old AC was failing and we were experiencing a ten degree difference in temperature between the front and back of our house. Dav performed all sorts of airflow diagnostics that led to interesting analytics to help design new duct work and which tonnage of AC to use. He also recommended a fantastic HVAC installer whom we also recommend. We are incredibly pleased with the outcome. Dav's fee was less than if we had used a contractor and when we plan to put solar panels on our house, we will certainly use him again. His work certainly added value to our house."
“Dav should conduct his own seminars in professionalism and customer service skills, as it is rare to find these days. I was given the run-around from many different companies, but Dav took the time to explain the process and referred me to the right person. Although his service and expertise is not required at this time for this particular project, I will definitely hire him in the future and recommend him to my colleagues. Thank you again for taking the time and it does not go unappreciated."
“David is a true professional with a passion, deep understanding, and expertise in all things air. Not only did he help my system work better, but helped me understand my overall system, money saving tips, and maintenance. Truly a value when a rating is needed — and I would bring him in at the beginning of the project for maximum benefit. Highly recommended."
“We are a HVAC company in the South Bay area and have had David out on 20+ projects to do HERS testing. He is very professional and knows his craft inside and out. We would not hesitate to recommend his company anytime."
“We were in need of a new HVAC system for our house and were hesitant to rely simply on proposals from installers who might be motivated to suggest more expensive equipment than we need. We wanted an impartial resource, someone with real expertise who could help us understand what we needed (and what we didn't), put together an efficient plan for our house, and help us interpret the proposals from different contractors. Dav was exactly what we needed. He's very smart, thorough and impartial. And just a nice guy all around. He went above and beyond across the board and I'd recommend him to anyone considering a new HVAC system for their house."
