After having six service calls with another company, my wife and I were exasperated. Our gas burner kept shutting off, and the other company kept charging us for repairs that didn't solve the problem. I called Clevco Mechanical, and they didn't leave until they figured out the cause of the problem. Rick was at our house for 9 hours doing diagnostics, calling the manufacturer, and then determining the course of action. He helped us work with our insurance company when it was determined the root cause was a power surge that damaged our gas boiler. Rick replaced it in record time. We couldn't be any happier with his service.
I recently had the pleasure of working with Clevco Mechanical for an HVAC project in my home, and I couldn’t be more satisfied with their service. They installed new ductwork and two heat pumps, and the experience from start to finish was exceptional. From the initial consultation, the team at Clevco Mechanical was professional, knowledgeable, and attentive to our needs. They took the time to explain the best options for our home, ensuring we understood the benefits and features of the heat pumps they recommended. The installation process was smooth and efficient. The technicians were punctual, respectful of our home, and left the work area clean each day. They demonstrated great attention to detail, ensuring the ductwork and heat pumps were installed perfectly. What impressed me most was their commitment to customer satisfaction. They followed up after the installation to ensure everything was working correctly and that we were happy with the results. It’s clear that Clevco Mechanical values their customers and takes pride in their work. Overall, I highly recommend Clevco Mechanical for any HVAC needs. Their expertise, professionalism, and dedication to quality service make them a top choice for anyone looking to improve their home’s heating and cooling systems.
I highly recommend Clevco! We have had them complete multiple jobs for us over the years and will continue to use and recommend them! They are always responsive and timely and do great work. They are always professional and have been able to assist us with both plumbing and HVAC issues we had on our end. It’s hard to find trustworthy and quality work and they are both! I’m always happy to recommend them to family and friends.
My wife and I bought our first home three years ago and from the get-go CLEVCO was there to service our every need from plumbing to Hvac. With the house being built in the early 70’s, a lot of the plumbing was on its last leg, with many leaks and drainage issues, but the CLEVCO team knew how to handle it. When our central air stopped working during a heat wave last year, they were there within a couple hours to bring my family and I relief. If you are in need of any plumbing, HVAC, or electrical work for your home/business, you won’t be disappointed if you go with CLEVCO.
Clevco Mechanical was extremely responsive and helpful for us. Every part of the process was very impressive. The tech who came out was very knowledgeable and professional. I would highly recommend them for anyone looking for Plumbing, HVAC or electrical work.
