DeMarco Mechanical Services came highly recommended after another company left us with unresolved HVAC issues. Adrian and his team not only fixed the problems but also suggested energy-efficient solutions that have saved us money monthly. Their professionalism and commitment to quality have made them our go-to for all HVAC needs.
I was thrilled with Adrian professionalism when he installed our new gas line and oven. So impressed, I had him return the next day to install an air conditioning unit. He purchased the unit, arrived promptly, and completed the installation without causing any damage to our drywall by feeding the lines above the ceiling. His attention to detail and respect for our home were evident throughout the process.
Adrian from DeMarco Mechanical Services installed our new gas line and oven. His professionalism and attention to detail impressed us so much that we had him install a new air conditioning unit the following day. He ensured no damage to our walls by feeding the lines above the ceiling. Highly recommend!
This is our second time working with DeMarco Mechanical, and once again, they exceeded expectations. They resolved previous HVAC issues and suggested energy-efficient solutions that will save us money monthly. Adrian and his team are skilled, honest, and truly care about their clients.
This is the second time I've used DeMarco Mechanical Services, and both times they’ve been excellent. They’re always courteous, leave the space clean, and don’t overcomplicate things. I love how responsive they are and how quick they are to get someone to your door. They’ve earned my trust for sure.
It’s hard to find companies that don’t try to take advantage of you these days, but DeMarco is the real deal. I called them in for what I thought was a major HVAC issue, and instead of pushing a replacement, they fixed a small part and saved me a ton. That kind of honesty earns lifelong customers. Thank you!
The work was completed as promised, and the new water heater works well. However, I felt communication could’ve been better. I had to follow up a couple of times to confirm the appointment, and there was a small delay in arrival. That said, the tech was professional, and the price was fair.
I don’t usually write reviews, but I had to for DeMarco Mechanical Services. My boiler broke down late at night, and I honestly didn’t expect anyone to help until morning. Not only did they pick up the phone, but they had someone out in a couple of hours. The technician was calm, helpful, and had the heat back on before sunrise. Total lifesaver.
Scheduling was a breeze, and the team at DeMarco Mechanical was super friendly. They installed a new A/C unit in my home, and the whole process was smooth and efficient. They took the time to explain how everything worked and answered all my questions without rushing. It’s rare to find this level of service these days.
I had an issue with my furnace right in the middle of winter, and DeMarco Mechanical Services came through for me. They showed up on time, diagnosed the problem quickly, and had it fixed the same day. The technician was respectful, neat, and clearly knew his stuff. I really appreciated the transparency in pricing too—no hidden fees or upselling. Highly recommend!
Amazing service. Was very happy with it. Super nice and friendly person. Very experienced and educated in HVAC. Reasonable service price as well. Overall very happy with the service.
I had a plumbing emergency at my rental property, and DeMarco Mechanical Services was a lifesaver. They responded within an hour of my call and arrived promptly with all the necessary tools. The technician quickly identified and fixed the leak, saving me a lot of potential damage. I was really impressed with their speed and efficiency. I’ll definitely be calling them again in the future!
DeMarco Mechanical Services has been our go-to company for maintaining the HVAC systems in our office building. They are always professional, on time, and provide reliable service. Recently, they helped us with a complex ductwork issue that was affecting airflow in multiple areas of the building. They got everything sorted quickly and without any disruption to our daily operations. Highly recommended for commercial clients!
DeMarco Mechanical Services is my go-to for any heating and cooling issues. I’ve used them for both routine maintenance and emergency repairs, and they’ve never let me down. Their technicians are always on time, and their work is consistently high-quality. They make sure everything is running smoothly before they leave. Definitely trust them for any mechanical work.
I’m really pleased with the service I received from DeMarco Mechanical. Their technician was professional and quick, diagnosing the issue with my furnace in no time. They also didn’t try to upsell unnecessary parts, which I appreciate. The only reason I’m not giving 5 stars is because I had to wait a day for the technician to be available, but once they arrived, everything went smoothly!!
I called DeMarco Mechanical Services after my air conditioning unit started making strange noises. They were quick to schedule a visit and arrived right on time. The technician was friendly, professional, and immediately diagnosed the issue. They had the parts needed and had everything fixed in no time. The price was more than fair for the work done. I’m so glad I found a trustworthy company for my HVAC needs. Highly recommend.
I've been using DeMarco Mechanical Services for over a year now, and I can’t recommend them enough. Every time I need HVAC work done, they respond quickly, are always on time, and provide top-notch service. Recently, I had a problem with my air conditioning unit, and they had it fixed in no time, ensuring my home stayed cool during the heatwave. Their team is professional, knowledgeable, and really takes the time to explain things clearly. It's refreshing to find a service company that truly cares about the quality of their work and the satisfaction of their customers. Highly recommended!!
DeMarco Mechanical Services did a great job installing a new water heater at my home. The team was prompt and efficient, and they walked me through every step of the process. My only issue was the wait time for scheduling, but once they arrived, they were quick and professional. Overall, a solid choice for plumbing and heating needs.
I recently had DeMarco Mechanical Services come out to fix an issue with my HVAC system, and I couldn’t be more pleased with the experience. The technician, Mike, was professional, courteous, and had my unit up and running in no time. The pricing was fair, and they didn’t try to upsell me on unnecessary services. Highly recommend for anyone looking for reliable HVAC service.
