"Job done fast "

"Tech was on time,. sending text ahead of time saying he was on his way. He explained everything to my husband and I about what the l2 year old gas furnace needed and we had him replace the circuit board while he was here."

"They did the work, thoroughly explained everything to me, gave me maintenance tips, and recommendations for future projects. Their estimate was lower than the competitor's was. They had everything they needed. They were great."

"Matt did an excellent job installing 4 ceiling fans/lights. Professional, well-spoken, and knowledgeable - at a reasonable price. I definitely plan to hire him for another larger project."

"though I appreciate the emergency Saturday service call (cost 169.00), I thought the additional charge of 303.00 (450.00) for a diagnostic check and repair ( no parts necessary - just less than a hour of manpower) was a bit exorbitant. perhaps I failed to realize that heating/ac personnel are paid on the equivalent scale as neurosurgeons."

"We have used Dzo countless times for a new system servicing, and now coming out multiple times to check on our systems, especially before the big storm we have coming this weekend. We are blown away by the professionalism and the knowledge they shared with us as well as prepping for the storm, I can't imagine using another company for our HVAC needs. "

"Zach fixed our ac yesterday, and he was wonderful and very helpful!"

"Overestimated the time to complete an 9 hr job by scheduling a 16 hr window (2 guys x 8 hrs) and charged for 16 hrs regardless. I'd imagine they did the same for the materials, 60 feet of duct needed but they quoted 200. Got the job done, but probably twice the price of what it should have been."

"Craig & Greg were very professional in their dealings. Prompt and on time to complete the work. They delivered the water heater and installed it. Hauled away the old water heater. Work was completed to our fullest satisfaction. I would recommend them and I will hire them in future."
