DZO Mechanical Heating and Cooling

I used DZO mechanical to install a new hot water heater at my home in Broomall, PA. They sent a technician, my brother, Shane. He did a great job! Install was quick and efficient. Job well done, and very nice person to work with. I would recommend working with DZO and Shane for your future needs.

Andrew T. replaced our filter and moved our thermostat, and the experience was fantastic. He was friendly, professional, and very detail-oriented. He patiently answered every question I had and made sure everything was done right. Thank you, Andrew and DZO Mechanical! I’ll definitely be using your services again and recommending you to others.
