Was able to get a technician on site next day. Showed up about 30 minutes into the time window. Diagnosed the problem in roughly 10-15 minutes, had it fixed within the hour. Very professional, great job.

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.

Gas Furnace / Forced Air Heating System Repair Service
$95
Relieved - that's how I would describe working with Carroll Mechanical. Ever since another company installed my furnace 6 years ago, I don't think it was ever working right. A number of companies have come over the years but nobody was able to properly diagnose the problem until Drew from Carroll Mechanical showed up. He was wonderful from the start and had over 50 years of experience in the trade. He spent the whole morning at my house running a full diagnostic, including a detailed combustion analysis plus measurement of gas pressures, duct air pressures, air temperatures, electrical readings etc.... he explained them all to me patiently like a good doctor and told me we what we needed to do - adjust supply gas pressures and increase the size of the exhaust flue to get the right air/fuel balance. Previous companies just wanted to get in and get out, but these guys took their jobs seriously and were just lovely to deal with. Insanely smart, caring, and reasonable people.

Gas Furnace / Forced Air Heating System Repair Service
Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected.

Heat Pump Repair or Service
I would absolutely recommend Carroll Mechanical. Their customer service was exceptional. After our heat pump failed, I reached out to learn more about upgrading our system. I spoke with Janel and she quickly scheduled an appointment for their expert (Chris) to come out to our house and talk us through our options. He educated us on the different systems on the market and the pros and cons of each. He was honest and not pushy (unlike some companies in the area?). The quote they sent was detailed and transparent. We decided to go with a new energy-efficient system and were able to schedule the install for the next day. The high efficiency system qualified for a tax credit and utility company rebate, which Carroll Mechanical handled for me. That added up to $4k of savings!! The install team was professional, courteous, and took their time to make sure everything was installed correctly. What i loved the most was the attention to detail. They took the time to explain how to operate the

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.
