PERFECT!  PROFESSIONAL FROM START TO FINISH. CAN'T SAYS ENOUGH GOOD THINGS. WILL NEVER USE ANY ONE ELSE.

We've had previous problems with the unit. It's been making crazy noises again so we called Dayco to come out and check. They were very prompt in returning my call and able to schedule me for the next day. Jerry arrived on time and was very nice and professional. He did a thorough check and didn't find anything amiss and even gave us some helpful tips. Thanks, Jerry and Dayco!

I contacted several A/C companies for estimates. Dean at Dayco was very professional from the first visit and provided a detailed estimate for several different seer systems. He answered all my questions while I was evaluating the various companies & estimates. I think his price was very competitive. His estimate included a detailed list of all the work included for the price. Because i was replacing a 3.5 ton unit, he had to install an additional air return duct and this was included also.
Dean and his team arrived on time on the day we scheduled. His team was very professional.  They worked all day, going late until about 7pm  to finish the job in one day. They had to install one additional air return, and also added one air supply duct at my request in our master bedroom. They were very careful to clean up, both in the bedroom and in the basement. They hauled off all of the old system.
Dean explained how to use the new thermostat and went over the entire system with me. He answered all my questions. The price was exactly what he quoted me, even after adding the extra supply duct.  The new system is working great, and our house is very comfortable. He also included one year of service at no additional cost. I will certainly contact him when the upstairs unit needs replacing. Great job!!!

Service man came out, did some checking of the furnace and thermostat, found broken wire by outside condenser, fixed the connections and tested to be sure it was operating.

it went good.  It was an Angies' list deal.  There was some confusion over the price, but when I mentioned the coupon # the took care of it.  I will have them provide an estimate for my upgrade.

I talked to Dean (the owner) and his son over the phone to set up an appointment to access my needs after reading reviews on Angies List and other local reviewers. Dean came out and surveyed the entire house, we talked about several options, pros and cons and efficiencies of different systems.  Dean is very easy to talk to about this complicated subject matter and at no time seems condescending or overly technical.  Dayco is NOT the type of company that sends out a high pressure salesman that tries to baffle you with numbers and data to sell you the highest cost system to maximize their profit!  Dean sent me several options/estimates the next day with a plethora of useful information to help me decide what I would need.  The workers fervently wear temporary booties to keep your home cleaner then they left it and are very knowledgeable in their craft, they also follow up with calls and information.  Our new system is flawless, it's like living in a new home, walking from room to room and not having a huge temperature/humidity gradient is a pleasure.  I'm really looking forward to saving money this summer with this ultra efficient system.

Install went perfectly. Dean along with his crew were able to install both units the same day with little to no impact on my activities for the day. They crew left a perfectly clean site both inside and outside.  They vacuumed up the insulation that fell onto the carpet from the pull down attic steps, always wore shoe covers in the house, and cleaned up the yard where they put in the AC condensers. All of the DAYCO crew were very professional and nice taking the time to introduce themselves.  They were excellent around my two dogs enduring the barking as they came indoors and out.
I plan to high DAYCO again to replace the third HVAC unit in the future.  I can recommend Dayco with the highest level of confidence.

The technician arrived early - about 15 minutes before scheduled time.  A good thing since so many are late.  He replaced some freon at no charge (pleasant surprise) and also gave me a $25 discount coupon (which I was not expecting and another surprise).  I have used another company in the past, and I definitely felt Dayco was treating me more honestly and fairly than the previous company (that always told me I needed something new each time - thus costing MUCH more money each visit).  Great job!

The representative was on time, cordial and very professional.  He
informed me about my system, its age and how long I should expect for it
to last for the condition it is in.  He explained how my two systems
operated and that almost no maintenance on my part was needed.  He
signed me up for annual service and was given a coupon by the company
itself for a discount beyond what I expected.  I priced this out with
the current Costco HVAC dealer who was $60 more for the exact same
annual service.  Thank you Dayco and ty to my service person Bob. 

We actually ended up using them for a complete HVAC replacement after we had it serviced and found out all the problems. We were very happy with them.

Excellent, as described above.

When placing the call to have the service done they were able to book the appointment for just two days later and they were very friendly when talking with them. Jerry was the technician that arrived at home within the time frame given to me during the initial call and also called me when he was about 20 minutes out so that I could escape from work to meet him. After a short conversation of why I called for the service he started his inspection. To inspect the two units it took about 30-40 minutes and when he was completed he took the time to explain to me what he did along with the outcome of any tests that were performed. 
My overall experience with Dayco and Jerry was professional, courteous, and informative. I will use Dayco in the future along with recommending them to friends and family.

Good overall.  He was very responsive to any questions/concerns.

Very professional and knowledgeable staff finished the job the company promised.

Dean sets the bar for excellence in every area of service. I have never been disappointed with the quality of his work, punctuality, willingness to clearly explain what is being done and why, and doesn't sell a customer something that is not needed. He is thoroughly knowledgable about his business and very professional. I trust his judgment and advice. Philip, who is the person I speak with to arrange appointmentsis pleasant, professional and always willing to assist.
The overall quality that sets Dayco above their competition, is the consistent philosophy and execution of excellent customer service beginning with the initial appointment setup through the completion of the service call.
I would, without reservation, highly recommend their services and look forward to knowing I can depend on them for future heating and airconditioning system needs.

They were polite and punctual, but the messae they gave us was disappointing.

Good job!  This was really helpful because our tennants expressed unfounded concerns about the HVAC, and this inexpensive service quickly put a complete stop to that because the technician was able to give both systems his blessing.

As I reported before on the work Dayco Systems has done for us and our home.  I thought I needed to report one more time.  At this point I do think I have met all the employees except for Phillip.  His is the voice behind the phone when I call in a panic that I need to reschedule or have allowed so much time to pass.  As I mentioned in my previous report back in July (work was done in May) that Dayco was very patience with me and was going to have them come out to remove all the duct work and replace the heat and air units in our garage apartment. Ben and Ryan arrived at 9 am and were here until sometime after 7 pm.  They were professional and as I asked if they would like some cold water to drink, they both replied no thank you, we each have a gallon with us.  I even offered them lunch but they had that as well.  I felt very comfortable around them as I was in and away from the house often.  Ben even asked me questions and explained certain situations so that I was informed of what they could do at no extra cost.   As they finished they had cleaned up all areas and I found the floors in better shape than they found them. (I was expecting a huge cleanup for myself). They also told me that Bob would be out the next morning to set the units for operation. As expected Bob was here on time and to the point, but very polite. He instructed me on the dos and don'ts with the thermostat.  Some of it I knew and some was new to me.  I was thankful for his information so that I could use his instructions to tell my teenagers that what they have been doing could cause more problems than good.  If you have or have had teenagers then you know they know everything!  Again, thank you Dayco Systems for a pleasant job well done.

We knew we had to replace 2 forced air heating furnaces (they were already over 20 yrs old). I joined Angie's List specifically to find local contractors who had good overall scores/reviews. I chose the top 2 to contact and request an estimate. Both companies (Dayco being one) responded the same day. Each was professional, prompt and polite. Dean from Dayco went an extra step of wearing boot covers before entering my house. He is a very personable man, and explained everything to me in detail. 
Besides the 2 furnaces, he was going to replace the ancient thermostats with digital ones; bring the flue pipe up to code; install a safety switch and pan and a couple of other things. He also gave us a surprisingly affordable estimate - on two levels, which is not something the other company did. Dayco is a Trane dealer (a brand I had actually heard of, though I am in no way knowledgable about heating units), and said we had a choice of 'builder grade' or 'residential grade'. Dean did not try to guide me toward either one, he simply stated the differences. We chose residential grade, which was nominally higher, because of the insulation and placement of one unit in our attic. But it was nice to have the choice presented to us.
I let Dean know on Friday that we would like to contract Dayco's services - and he scheduled the installation for Monday! He told me the crew would arrive between 9-9:30 am, and he called at 9:05am to let me know they were on the way. They arrived before 9:30. The 3 man crew was also very polite, personable, professional and did their best not to interrupt me during the installation - as I run my business from a home office. I also have a rather large, noisy dog - and they were all fine/relaxed with him in spite of his frequent protective barks. 
The crew covered all carpeted areas under the attic access. They wore boot covers. They worked steadily through to a brief lunch break, and finished installing both units, hauling the old ones out, leaving a clean house at 4:40pm. Dean came at the end to inspect the work, explain the new thermostats to me (they have scheduling), and presented the invoice which we promptly and happily paid. 
One of the best experiences we've ever had with work performed on our house. We've already recommended him to our next door neighbor, who is likely going to contract them as well. I would definitely hire Dayco again - and may need to sometime next spring or summer, as we also have one ancient air conditioning unit.

They did a good job. We now have a service contract for a year with them. I would recommend them.

They came at the time agreed upon, performed an inspection, told me exactly what to expect from my outdated unit and were very professional. I know the unit is near the end of its life, but they advised me to wait until I needed to replace it as energy costs will not completely offset the cost of the new unit. When it comes time to replace the unit they have already earned my business.

Dean comes out twice a year for maintenance.
He is also very responsive if there is an issue with one of the systems.

Dayco systems did a fantastic job for a very fair price.   Dean came out to provide a quote and spent a lot of time talking through options with me.  
I was originally going to just have ductwork added to the new addition, but when I mentioned that I also had airflow issues with upstairs bedrooms, Dean brainstormed options for getting more air to them.   We ultimately settled on a way to run new ducting from the crawlspace system, through the first floor, into the second floor attic, and then branching to supply both upstairs bedrooms.   I hadn't even considered that option before, and it was a great idea.   Dean also reviewed the size of my AC and Furnace systems and determined that they were large enough to cover the extra space.   So, he didn't even try to sell me a new system that I didn't need, which I appreciated.
The install went very well and took two days.   Ben and Ryan were both very friendly, knowledgeable, and hard-working.   Their work was top notch, with no issues.
The result of the install has been very good.    The airflow to the new addition has been very good as expected.   The really pleasant surprise was the extra airflow in the upstairs bedrooms.   The extra cooling has made them livable in the summertime again, so it's like getting two bedrooms back.   :)    (Full disclosure:  Part of the benefit also came from my install of new wall insulation, and a new attic fan in the ceiling above.   But there was definitely a major lack of air flow up there, and Dayco corrected that.)
Overall, I highly recommend Dayco and will definitely be using them again.

It went very well. They were able to come out within two weeks, which worked well for me. They were on time and cleaned up after they were done.
