Cane out right away and did a great job
Josh Bennett was so amazing and helpful! I’ve been using Dayco a while but he was super professional and nice. Thank you so much
The team has been excellent to work with, from install to maintenance to our first minor repair the other day. They’re truly customer-first and do high quality work. Harold was great to work with.
Great company with awesome technicians and customer service.
George was thorough, on time and knowledgeable. I highly recommend him!
George Frank did a fantastic job with a tricky repair job! Very knowledgeable and professional! Highly recommend him and Dayco for maintenance and support!
Alex Cruz arrived on time and did superior work; outstanding. He was efficient and thorough. His recommendations to improve performance of my HVAC system are economically sound. His interpersonal communication was on point. If possible, you can earmark him for my residence and train for greater responsibility; A great heir.
Came out right away after hours for busted pipe. Replaced the pipe and our gas hot water heater. Price was really reasonable. Phoenix and Michael were friendly and professional. Did a great job.
2/24/26 update: If your capacitor needs replacement and it's the regular kind... think twice about Dayco. I have learned that if you have to replace your capacitor... Dayco doesn't even offer the option of replacing your regular common kind of capacitor... you have to upgrade to a turbo capacitor... a $500 to $600…
Recently had repair work done on our HVAC system. Had the blower motor replaced. Super quick turnaround and quality work done by Alex C. Thanks!!
I am just amazed by, & impressed with, this company! I had an AC emergency last night, Sunday evening, & when my current HVAC company was unable to come out, I quickly proceeded to randomly call several other HVAC companies, before ultimately landing on Dayco. Not only was their answering-service agent delightful,…
Jon the technician was very personable, diagnosed the problem quickly, answered all of my questions, and completed the repair in a timely manner. He showed me how to keep the problem from happening again as well. It was a very good experience. I cannot say if the price for the service was reasonable or not…
Have worked with Dayco for over a year (Shaun, Jon V. and others) to replace and repair A/C systems. I cannot be more pleased with their professionalism, quality of work and just plain good manners. Everything so easy during stressful times! Highly recommend!
I have used Dayco for my HVAC needs for over 20 years. Brian Z is my technician and has been for quite some time. He is prompt, professional, highly knowledgeable, and excellent at communicating situation to a non-professional person. He is wonderful to work with. He is one of the reasons I especially so highly…
Brian stayed until the AC problem was diagnosed and solved. Communicated with us effectively about the replacement parts, which included a breaker.
Excellent Job!!!!!!
This company is the BEST! Reliable and trustworthy! Staff is friendly and knowledgeable! HIGHLY recommend!!
Professional. Prompt and courteous. Hopefully system is fixed since a new unit.
Fast and prompt with emergency repair.
Our technician John was courteous and very professional.He was ahead of schedule and called to see if he could come earlier. He showed up when he said he would and set straight to work. He was very thorough and quickly identified the problem. Very pleased with Dayco and their staff. Hats off to John for his excellent service and attitude.
