I previously used the family owned company with the green trucks, what a joke they were! DZO answered the call and had a technician at my house in a little over an hour. I had to replace my heater and DZO was able to install the following day. Ill be sure to recommend DZO to anyone I know. Thank you !!

We asked DZO Mechanical to perform preventative maintenance on our (2) HVAC units in our leased warehouse space in Broomall. From the first phone call to the last, the entire team at DZO was easy to interact with, extremely professional and knowledgeable. Invoices were reasonably priced and I am so glad we called them to provide maintenance. We even learned that one of our units has a small issue now that could potentially lead into replacement of the unit. Thankfully, we caught that issue in time. Big thanks to Lou, Kevin & their excellent team of technicians!

DZO removed my entire old, outdated heater and AC system the whole thing and took all the waste. Then, their team of experienced and friendly technicians installed the most efficient, new, cost-friendly equipment. The entire team was so nice and polite. Additionally, the total price was considerably less than other local estimates. They made me feel like family. Highly, highly recommended.

I have a pretty old 3 zone heating boiler system and the upstairs zone just stopped working and provided no heat in the bedrooms! I called DZO and spoke with Kevin who listened and was decisive to get someone out as soon as possible to take a look. Both Kevin and Lou were able to access the problem and get all zones working again quickly and efficiently!!! We all agreed the Unit should be serviced and Felton was sent out 2 days later. Felton was extremely knowledgeable and thorough and ensured that the boiler was where it needed to be!! Felton did an amazing job of explaining anything I may need to know and made sure the boiler was safe with small children in my house! I highly recommend all of these nice gentlemen to anyone!!! Will be using them again if/when the need arises!!! Thank you DZO!!

I am currently renting a studio space in a building and had no heat/AC. The building owners hired DZO Mechanical to install the new unit. Felton and his team did a great job. They worked long hours to get the job done and also cleaned and closed my business as if it was their own. I was very comfortable with them here working, even while I was working at the same time. They are very professional and informative when it came to educating me on the new system. I would definitely recommend them. Thanks DZO Mechanical (Felton)

Our central air stopped working over the weekend and on the hottest day of the year. My husband called Louie and he returned his call the same day. He promptly sent his technician out on Monday. Felton was knowledgeable and explained what the problem was. Luckily, he was able to fix the problem quickly. I would definitely recommend DZO. Fast and efficient. Thanks Lou!
