All reviews for DZO Mechanical Heating and Cooling

I had DZO out a couple of weeks ago in Newtown square to insulate my ductwork. Dan Lannon and Luke Moyer did a great job and were in and out in a Day. Would recommend without a doubt.

DZO has done several repairs on our heating and air conditioning unit. I spoke wit a young man named Bob who was courteous on the phone, We received quick service at a reasonable price.

Shane came out to my home in Newtown Square and fixed my heat. He came within the day I called him, and got everything squared away within two hours. It was a freezing cold day, so he really was a life saver for me and the family. 10/10 recommend.

Edward McElhinney was absolutely amazing to work with. He was extremely informative and took the time to explain everything clearly, which made the entire process feel stress-free. He provided a fast and fair quote for my office building in West Chester, PA, worked diligently, and stayed on top of every detail from start to finish.

My oil heater was blowing out black soot so they sent Shane over to deep clean and service check the heater. Also changed the oil filter. He was in and out and had a very fun but professional personality.

Chris was able to do preventative maintenance on our two systems here in West Chester, PA. He came recommended by our neighbor, who also had a great experience. He did a great job and we already booked him for Spring.

I was getting no heat from any of the hits and the house was freezing. I called my guys over at DZO. Shane came over squared everything away and now my house is all back to normal. Sea Isle City, NJ

I called DZO and Shane came out to my house in Marple Pa. He replaced our old water heater and got it running right away. Could barely even tell they were there! Highly recommend.

Bob and the DZO team were quick and helpful in resolving my service issues in Westbrook Park, PA. We cannot recommend them enough. Bob was so communicative throughout the whole process.

We recently had DZO out to do maintenance for our two furnaces here in King of Prussia. Chris was the technician and was very informative. Thanks DZO, we will see you in the spring.

Thank you so much for your quick response. Chris was here to our Broomall house in what felt like minutes after I called. Everything is good to go now. Very appreciated

Chris came by and helped fix our heating issues. We are located in South Philly. He arrived punctuality and was very through with his assessment. He took the time to carefully explain the process, helping us understand the issues.

Edward McElhinney was a pleasure to work with throughout the entire process. He was knowledgeable, responsive, and made a point to walk me through each step so there were no surprises. His pricing was prompt and reasonable for our office building in West Chester, PA, and his attention to detail was evident from initial discussions through project completion. The experience was smooth, professional, and well managed from start to finish.

I couldn’t be more delighted with the outstanding service from Andrew T at DZO heating and cooling. He rushed to my house in Clifton Heights Pennsylvania to get my heat back up and running right in time for the holidays. Best company in delco

My old heater does not cover much of the upstairs so I called DZO and they sent Shane over to install a minispilt in the master bedroom. Very quick! I would highly recommend.

Bob and DZO Mechanical were quick and efficient with my service call in Philadelphia! I will definitely use them again! Top notch service. Such a pleasant experience. Thank you all again!!

I called up DZO because my AC went and they sent over Shane to replace the indoor and outdoor. He was very nice and helped me understand the basics of how it worked. Thank you guys for the help! Job was done in Newtown Square, Pa.

DZO Mechanical truly saved the day. Bob and the DZO team treated me like family and clearly knew their stuff. They were fast, friendly, and incredibly helpful with my service request in Havertown, PA.

Ryan Sexton did an excellent job replacing my boiler. I’ve never had a technician be as honest, knowledgeable and personable as Ryan. The fact that Aston, Pennsylvania has such great talent taking care of any and all HVAC needs is extremely reassuring. Thank you to Ryan Sexton and DZO Mechanical for being such a great help.

Shane helped me understand the entire process of why he thought I needed a new water heater and I was very happy with the final result and how quickly he was able to diagnose the issue and fix my issue. I’m glad i don’t have any other issues and he assured me it should last a long time. Broomall Pa.

I live in Brookhaven in Hilltop. Chris came out to service my heat pump. He was very thorough and was able to get my heat back up and running. I highly recommend DZO Heating and Cooling.
