Manuel and his hard working team put in a new AC unit for our condo. They’re great to work with — courteous, friendly and knowledgeable.

Jack Turner

Manuel with On Top Heating & Cooling did a great job fixing my A/C. The fan motor stopped working and he came out the same day. He explained everything clearly and gave me different repair options instead of trying to upsell me. I decided to go with the rescue motor to get me through the summer, and my A/C has been working great since. I really appreciate how honest and professional he was. Highly recommend On Top Heating & Cooling!

Star Flores

On Top Heating and Cooling installed a Mitsubishi 4-head mini split system in our home, and we couldn’t be happier with the results. Manuel and his team were professional, knowledgeable, and took the time to make sure everything was installed the right way. The system runs great, looks clean, and the attention to detail really shows. They kept the workspace clean and walked us through everything once the job was done. Highly recommend Manuel and his team if you’re looking for quality work done right.
