“Your HVAC done by Dave's or another vendor?”
“Got a better quote from them compared to Dave's world, who def tried to upsell me.”
“I’m getting mine installed in a month and a half. Dave’s world - going with a Samsung system with 5 indoor units and 2 outdoor - paying 20383”
The in-person experience with Dave’s World was exceptional. However, the automated phone service is abysmal. It was so impossible to get a response that we had to drive to the office in order to simply reschedule an appt. That in-person office experience was great but totally unnecessary and a waste of my time. Business will suffer unless this phone service is improved.
John from Dave’s World was prompt, polite and efficient. He explained things well. 10/10
Jon and Erik came to troubleshoot our mini-split unit that had leaked. They were both very personable and got right to work. They quickly found the problem…a clog in our drain line and were able to clear it. We were so relieved it wasn’t anything major. Thank you Jon & Erik..you were our superheroes today!!
Aaron was quick and did a thorough job cleaning my heat pump!!!
Ber satisfied that they solved our issue with Heat pumps not working.
