Jordan was incredibly professional and kind helping us with our HVAC system. We have had airflow distribution issues since we moved in. He quickly identified this as a damper issue and returned promptly to fix the issue and educate us on future use. Recommend 100% to anyone looking to have HVAC work done!

Brendan & Diego installed a Daikin unit in our sunroom. They were very professional, installed the unit in a reasonable amount of time, and left the work site clean! I highly recommend this company!!

Roy and the Carroll Mechanical team were lifesavers. Our heat went out and they were the only company able to send someone right away at a fair price... would definitely reccomend.

The professionals at Carroll mechanical were here today to install my new Goodman HVAC system. They were here yesterday to initially diagnose why I was having short cycling on my 25-year-old system. After realizing how much the cost was for a new motor, they recommended that the system be replaced and I agreed. They came in when they said they were gonna be here, did an amazing job installing the new system and disposing of the old system. After everything was installed, Diego did a walk-through and showed me how to install the new app on my phone so that I could control the new system remotely. I am so thoroughly satisfied with their work and would absolutely recommend Carroll mechanical.

Heat Pump Installation and Replacement
I got quotes from a few different contractors. Carroll Mechanical’s was very competitive. It was the best value so I decided to go with them. The installers were prompt and did a fantastic job. The new system works great and they walked me through everything before they left. I have an ongoing maintenance so I know they will continue taking care of the new unit and making sure it works well. Overall, very happy with my choice.

There were a few hiccups & this was not a smooth process, as I was promised. I was frustrated that the complete job took over a week to complete.

I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out.

I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical.
