“My 5-year-old AC went out over a 90-degree weekend.”

My 5-year-old AC went out over a 90-degree weekend. A company I’d used before told me the compressor was completely dead and it would take 45 days to get a new one, or they could replace the entire unit in 2 days for $10k. That seemed extreme for a 5-year-old system so I started looking for a short-notice second opinion. I called another HVAC company, Ralphs, and although they don't service my area in the city, they recommended Lucas Mechanical as a company they trust. Lucas had their tech, Carlos, out in less than 90 minutes. He replaced the capacitor ($90 part), and my AC was back. The compressor works fine. Recommended by another company and saved me $10k (minus the cost of the trip). Hugely thankful! I called Ralph's back to thank them for the recommendation and they basically said, 'we know they do good work.'

“My air conditioning was leaking all over my basement floor.”

My air conditioning was leaking all over my basement floor. Spoke with Sean at Lucas and he had his technician at my house that morning and started new installation of new furnace and a/c that very same day. I am extremely happy with management and technicians. They did a great job.

“I highly recommend Lucas Mechanical.”

I highly recommend Lucas Mechanical. One of the HVAC units in my commercial building was not working, and I needed to have it fixed before the next winter freeze. Carlos quickly deduced the problem and explained it to me in a logical and easy-to-understand manner. Since it was an older HVAC unit, I appreciated an alternative solution to fix it instead of just telling me to replace it. When the time comes to replace the unit, I will gladly hire Lucas Mechanical.

“Between multiple service calls at both my condo and my mom's house, I'm on a first-name basis with...”

Between multiple service calls at both my condo and my mom's house, I'm on a first-name basis with three Lucas technicians (Carlos, Martín and Matthew). With every visit, each of these guys has been professional and competent, and particularly thoughtful with my nonagenarian mom. They've each gone the extra mile in some way with every visit, and I am happy to be able to greet them by name.
