"The assigned technician, John, was on-time, knowledgeable, provided suggestions, and thorough. Oftentimes, people don’t realize how important this service is. If I were you, I would book AC Air Duct cleaning!"

"I was a little disappointed because I hired this company based on the reviews and the issue was not resolved the first time the pro came out and I had to pay twice for him to come back to adjust the same issue. I would have to say that maybe my pro was not as experienced in handling my heat issue but I would not dissuade others to not hire this company."

"Jon was immediately responsive and helpful. I explained my situation and that I was concerned I might need to replace my furnace (a opinion from another company). He stated he would just come do a diagnostic and we could go from there. That diagnostic fee was very reasonable. The tech came, stating that it was likely the "board" that needed replacing. They ordered the part and immediately came out and finished my mix. A HUGE RELIEF that I did not have to replace the furnace right before winter. So for once I felt like I was being dealt with honestly, and they went above and beyond. I will call them with ANY of my HVAC/Plumbing needs. Thank you Jon and the techs at Sync! I'm still WARM!!"

"Dan Rohde came to the house to assess what our needs were, and made a professional evaluation of the proper sizing for our purpose. Other potential providers oversized what we really needed. The installation team of Domingo, AJ, and Dave were extremely professional, solving an interesting challenge of drilling through solid rock to properly route all the lines. Very punctual; did a very clean job. No issues. AC is running well."
