I just wanted to shout out Trey for helping me out tonight. I found out my capacitor went out in my AC unit, and I couldn’t find one to replace it myself with it being so late. I saw Trey sitting in his van and I approached him and asked him for help. He was off and spending time with his wife on her lunch break. I explained to him what was going on and he was happy to help me out. I was very grateful for him to change my capacitor with how late it was getting especially on Easter Eve. Top notch service! I would highly recommend him to anyone needing any HVAC repairs or services.

Kacen Crosby Google review Β· January 2025

I recently completed a comprehensive renovation of my home, which included the installation of a new air conditioning unit and furnace shortly after April 2020. During my first summer in the house, I observed that the air conditioning system struggled to maintain a comfortable temperature during the peak heat. Frustrated with the situation, I reached out to Crosby’s and decided to replace the entire unit with one that was appropriately sized for my needs. It was disappointing to find that the initial company overlooked several critical details. However, I was pleased with the service provided by David from Crosby’s, who demonstrated professionalism and integrity throughout the process.
