Frequently Asked Questions for Air Quality - Indoor in Hayward, CA
Q: What are clients of Diamond Certified indoor air quality companies saying about companies in Hayward, CA?
A: Verified Art of Comfort Customer, 1 of 130 "His price is very competitive. The service was very good, they showed up when they said they would, did what they said they would and showed up on time. I have a friend who understands HVAC for a large commercial business and he said they did quite well and said the work was well done. I would highly recommend them. I chose them over Service Masters who did the original installation and service whose quote was $14,000 higher. It was not an urgent job and I knew what worked the best was to replace them together, so when it was time, they kept the same quote and were very professional and very nice." - Linda K. All Survey Responses for Art of Comfort Verified Hometown Heating & Air Conditioning Customer, 1 of 457 "We were very satisfied. They installed the heating and AC. They worked very hard and did everything possible to make sure we were happy with everything. The work crew is amazing. They come out every 6 months for maintenance, and I've been very pleased. What I liked best was probably the crew that came out to do the installation for the heater and AC. They had an excellent sense of humor, they enjoyed their work, and they were out there teasing each other, just very friendly, very energetic, and team-oriented. They enjoyed what they were doing, and it was very neat to see that they had so much fun doing their work. The guys who did installation were phenomenal. The one who came out the time before last to do the maintenance was so good and worked so hard. I was so pleased with him that I asked him to come out and do all of our services." - Mark B.
