Sherlock Heating and Air provided excellent service and a great price on the A/C unit at my old home. I was so happy with the experience that when I needed my A/C units moved at my current home, I called Aaron to take care of it for me. Again, he delivered another first-rate job. All of my questions and concerns were addressed in a prompt and professional matter. I would recommend Sherlock Heating and Air to anyone.

The service was exceptional and when they said they would be there, they were there on time! Both reps were very knowledgeable regarding our problem and did not try to oversell me on the parts that were needed to fix my A/C. Their pricing was very competitive and I will definitely be calling Sherlock Heating and Air Conditioning for all my HVAC needs.

My experience with Sherlock Heating and Air was wonderful! Aaron was always available for questions, and was able to give a detailed explanation of all my different options, always wanting to keep our budget in mind. The crews were knowledgeable, and dependable from the beginning till end. I have continually recommended this company to family and friends, and will continue to do so!!

I have had the pleasure of working with Aaron Sherlock on a few matters for my personal investments and was always so amazed by his professionalism, integrity and knowledge. As a Realtor, I know how important service can be. I have recommended him to all my clients when a heating/air concern arises. He has always made my clients happy and has been very thorough.
