Best HVAC Company in Metro-Atlanta, 6/29/2015

I had all the big name HVAC folks in the Metro-Atlanta area come out for an estimate on complete replacement back in September 2014. They all pretty much chose the same equipment, but the prices were... all over the place. Dayco systems were the cheapest and were very down to earth and our a true family business. They worked hard to complete my job and did a great job. They have been back twice since the install (once to replace a defective thermostat [no charge by the way] and one for a free 6 month maintenance, in which they did some duct sealing [no charge for this either]). I have recommended them to others and will continue to do so. HVAC system has been working flawlessly and I have also saved over $200 so far compared to the previous years bills.

Saved me from another company, 5/05/2015

I built my home in 2008 and unfortunately went with another HVAC company as my Air Conditioning contractor. Within a couple of summers, I began having problems. I was forced to buy a maintenance... agreement on a brand new system to get it working. After 3 years, it was finally determined that something on the unit was bad (no kidding...) and was replaced. System was OK for another couple of years. This summer, when I turned it on for the first time - nothing - would not work at all. I called Dayco. They came out within a couple of days and determined that the downstairs unit was dead due to faulty installation. My 7 year old unit needed to be replaced. Dayco advised me of my options and had my AC unit up and running within a few days. It actually works better than it has in the 7 years I've used it. This was a costly mistake on my part to go with a company that did not stand behind their work and serendipitously installed the cheapest AC unit available. I now have a Trane compressor that actually has me cold in my house. I can't say enough great things about Dayco and their entire staff.

These people were great! We called after hours and within less than a half hour, we received a call back. We received a call the next morning by 7:30 am to schedule a visit and they were there early for the noon appt. The tech was professional, nice and knew what he was doing. In the end, it was less expensive than we expected! NOT ONLY ALL OF THAT....we got a customer service check the next morning! Great! I highly recommend!!!

Great Service, Honest company

I have been using Dayco for several years to service my home and business. The prices are fair and the service is outstanding. My needs are always taken care of in a timely manner. It can be detrimental for a business to be without air conditioning. Every time I have had a problem it was dealt with the same day. I highly recommend this company!

Great A/C Company

They gave me the best price and they installed quickly. There was a small glitch with the system cooling but no dehumidifying but Dean came out and adjusted the system until it was perfect.

Great Customer Service and VERY Fast Response

I was having trouble with my HVAC units and called another company to fix it. They came out and "repaired" the wrong unit, charged us an arm and a leg and then called to tell us we still had a leak. I got Dayco's number from a friend and they were out the very next morning to look at the problem and give me a quote. They didn't even charge me a trip charge because I told them what the problem was and they offered to come and take a look at it to make sure that was it, and to give me a quote. They gave me a price less than the other company and were ready to fix it ASAP. Their customer service is really awesome. We had to pay quite a lot of money for the issue we had, but I felt like they were very honest and walked me through the problems that we were having. I felt that my money was well spent for the service I received, as well as how I was treated. I would highly recommend them to anyone needing service, and they are the only number I will call from now on. I would recommend them to anyone. Great service for a great price!

Excellent price and service

Heard about Dayco from a neighbor. I have multiple HVAC units that needed parts replaced from normal wear and tear. Initial HVAC company wanted over 50% more than what Dayco charged me! Very pleased about the fair price and quality of service.

Lives Up To His Reputation!

Dean lives up to his reputation again! Awesome service and very reasonable price! Had a problem with my furnace this morning and I didn't hesitate one second to call him. I was actually looking forward to calling him! And he picked up the phone right away and he was so courteous and so polite. He arrived here 20 minutes later and fixed the problem like in 10 minutes! He even thoroughly answered other questions I had about my furnace, and give me recommendation on what I could do myself, or if I prefer - his staff will be glad to do it. I decide to let his staff do it because they are so worth the money. I'm very happy with Dayco Systems, and highly recommend them! Thanks Dean! Johnny - Highcroft

Highly recommend

I called Dayco to service my furnace and they were able to make an appointment the next day. The pilot light was constantly going out and it was not running well. After inspecting, I was shown that I needed a new one. Bob, the tech, showed me the cracks in my old furnace and the singed wires (fire hazard). Not surprising from a 30+ year old unit. They were able to make the appointment the next day. Both times they were there right when they said theyd be. The price I was quoted was very fair and probably less than many comparable companies would offer. Im guessing with the improved efficiency, itll pay for itself eventually, but have not gone through enough billing cycles yet to compare. The guys that came out were friendly and got right to work. When they completed, they showed me the upgrades they made from the old one. As they were wrapping up, Dean, the owner came out to the house to take a look at the work and to say hello. He seems like a genuinely good guy that takes pride in his company doing good work. I would recommend his company to anyone and have done so with friends and neighbors already.

Dean, the owner of Dayco, is a refreshing individual to deal with. After talking to and receiving numerous proposals on replacing my 2 heat pump systems it was an easy decision to decide to go with Dayco. Dean discussed my options and suggested three different plans and prices to choose from. All were "upfront" and simple. Unlike all the other proposals. He and his crew did the work in a very professional and timely manner. He has certainly gained my trust, respect and return business! Nothing beats having the owner personally involved in meeting his customer's needs.
