Mike Borrego did an outstanding job! Very professional and knowledgeable on our system. He even showed up early and called ahead of time to make sure the time would work. He was quick to pinpoint the repair needed and had the part with him to fix on the spot. Our AC works great now! I'm sold on DayCo hands down. Highly recommended.

Seth came out to replace air filters and give an overall check on the HVAC system and was awesome! He was very thorough and explained everything in great detail.

Report
I have always used Dayco for maintenance etc. on my HVAC System - I always will. Dayco couldn't be better to deal with from scheduling the appointment, communicating the time of arrival, and continuing right on through to the completion of work. Seth, was my most recent technician and I'm thankful he was. He performed the routine maintenance on our system, but because he is so thorough, he was able to diagnose and fix a problem I was noticing recently and in the past. he explained what was happening, took care of the issue, and offered up his recommendations for future maintenance. I was relieved. Thank you Seth and Dayco.

Jesus and Dayco were great! He was super mellow and soft spoken. He squeezed us in at the end of his day which we really appreciated. Our blower to the heating system went out and they were able to assess and give a quote within 24 hrs. They'll be out tomorrow to replace it with a new one. Highly recommend Dayco and their team!

Arrived a little before scheduled time (which was great). He was very professional, introduced himself and was very personable. He did the maintenance efficiently and in the time he said he thought it would take him. Explained what steps he had taken and ask if I had any questions when he completed the routine maintenance. Great experience and company.

I had my home's air ducts system cleaned. Alan the Dayco technician did a good thorough job of cleaning the ducts and vents. He also did a good job of explaining what he did and answering my questions. I recommend this company for your heating and air-conditioning in your home. Service: HVAC duct & vent cleaning
