I had to get a new furnace put in just weeks before Christmas this year. Aaron and Nick did an excellent job on the new furnace. Very professional and cleaned up when they were all done. They showed me what they did and explained how the new one would work. I can tell a big difference in the house now. Job#RA812139 on 12-12-18

Technicians Bart, Jeff, Josh, and Mike worked to install Mini-Split AC at my my home on 1/7/2019. (Job H0901022). They did a great job. Everything was done neatly and on time. When they left everything worked perfectly and the house, inside and out, was immaculate. I also appreciated the communication with the installers from the beginning of the job to the last day (only 2 days). Bart called each morning to confirm their arrival time and tell me what work they would do for the day. Even before the job began the salesman, Joe Clark, communicated very well. After getting other bids I knew Holland was the best. Highly recommended.

After doing some research as to what I wanted, I did a web request to be contacted. The NEXT DAY, I got a call back and we scheduled an appointment with Doug. (As I side note, I did 4 other web requests and only heard from one other company???) Doug came out and showed me my options, and educated me on the best solution for my needs - my research was a bit lacking. 🙂 Doug was great to work with and worked hard to get me a great price on what I needed.
On installation day of Job # RA810163, the crew, Brad and Nevin, showed up right on time and got to work on my complete system replacement (AC, Furnace, Filtration, Humidifier, thermostat, the works). They were an absolute pleasure to work with - and tolerated my curious questions with a detailed answers and a smile. A bit later, a second crew of Damon and John came to help - two more great guys! The project moved along quickly and they were done earlier than I expected, but the install LOOKS like it took weeks - the tubing bends, vent routing, wiring, are, frankly, a work of art.
Before they left, Brad took time to show me the details of how to use my new thermostat, maintain my filtration and Humidifier, and entertain a few more "how does it work" questions. Everything was clean when they left are well - aside from shiny new equipment, you'd have never known they were there!
