"We needed to replace our aging HVAC system. It had various parts failing and wasn't worth it to keep repairing it.  Dayco went above and beyond all expectations! I had already received quotes from 4 other HVAC installers but just had a feeling that my search wasn't complete. I called Dayco based on the reviews I read on Angie's List and am so glad I did.
Dean was on time and was sure to put on booties before he walked in. He did a complete inspection of our house, carefully looking at our existing system and asking me questions about what worked well with our current system (ie when it was working, did it cool the house properly in the summer, heat in the winter) and what we were looking for. He quoted us a new 3 ton 2 stage unit that was very well priced.
There were a couple of things that stood out to me and why I chose to have Dayco do the installation.
1) Dean did not give me a hard sell. He simply stated what he thought best for our house based on how big the house is and other requirements. He didn't try to do a song and dance routine like many others had on what I needed and why. A couple of other installers had quoted me a 4 ton system and I asked him why 3 vs 4 and he explained why. Since I had had more quotes for a 4 ton, he assured me that if I signed him on to do the job, he would come out and do an intense study of the size of the house (Manuel J study) to be 100% sure that the 3 ton was what we needed. He said that if we had a 4 ton installed, the system would be too big and not cool/heat the house properly. He said experience told him we needed a 3 ton but was willing to do the the calculations for my peace of mind. When he did the Manuel J study, the calculations showed he was correct. This told me that the guys who quoted me the 4 ton were just out to get my money. No one else even talked about the Manuel J study. I really appriecated that not only did Dean educate me on it but was willing to do the extra work to prove he was correct.
2) His attention to detail was awesome! When he went upstairs to look in our attic, he was sure to take his booties off as to not track insulation back in the house and when he raised the stairs back into the attic, was sure to leave it EXACTLY how he found it. My husband hates having the string for the drop down stairs hanging down and Dean remembered to pull it up. A little thing for sure, but it is the little things that mattered. That told me that he'd pay attention to every detail on the job.
The removal of the old system and the installation of the new went very well. The team he sent out to do the work was professional and did a great job. Dean came out halfway in the install to inspect everything.
We couldn't be happier with the new system. Spending $7,0000 on an HVAC isn't the most fun thing to do, but I like knowing that we received a great deal on the product and the service. I HIGHLY recommend Dayco for all your HVAC needs.
