Outstanding Experience with Dayco Systems — Highly Recommend! We couldn't be more pleased with Dayco Systems and the entire team that installed our new Daikin HVAC systems! From the beginning, Shaun did an excellent job helping us select exactly what we needed. He even redesigned the airflow to a bathroom that had been a problem for years—and it now works perfectly! Dayco sent two crews so both of our old HVAC systems could be replaced in a single day. Patrick and the installation team did an outstanding job, taking great care of our home throughout the process. They wore protective booties inside and left everything spotless, both inside and outside. When the airflow to our master bathroom needed a little additional adjustment, Patrick came back and took care of it promptly. We were also pleasantly surprised by the price. Our top-of-the-line Daikin variable-speed systems actually cost considerably less than the comparable Trane and Carrier systems quoted by two other companies. Perhaps most importantly, Dayco really stood behind its work. When one of the new systems wasn't performing properly, Jacob and Ben worked directly with Daikin to diagnose and resolve the issue. Ultimately, they replaced a major component of our downstairs system at absolutely no cost to us. They stayed with the problem until it was resolved, which says a great deal about the company's commitment to its customers. It's easy to find a company willing to sell you new equipment. What's much harder to find is a company that combines competitive pricing, excellent installation, thoughtful problem-solving, and outstanding service after the sale. Dayco Systems delivered on all counts. Shaun, Patrick, Jacob, Ben, and the entire team have earned our trust and appreciation. We couldn't recommend Dayco Systems more highly!

Thank you for this incredible 5-star review and for taking the time to share such a detailed account of your experience! We're thrilled Shaun helped you find the right Daikin systems for your home while addressing longstanding airflow concerns. It's wonderful to hear Patrick and our installation crews completed both replacements efficiently, treated your home with care, and followed through on the additional adjustments. We're especially proud of Jacob and Ben for working closely with Daikin to resolve the performance issue and ensuring everything was operating as it should. Standing behind our work and earning our customers' trust long after installation is incredibly important to us. We'll be sure to share your thoughtful recognition with Shaun, Patrick, Jacob, Ben, and the entire team. Thank you for choosing Dayco Systems and for your outstanding recommendation!

Dayco Systems Heating & Cooling Review I’m super grateful for Josh Bennett’s expertise in heating/ cooling and all the intricacies involved - he knew I had a clogged condensation pipe coming off the furnace, leading to the outside of the house. This was causing my thermostat to shut off sporadically and mostly be 100% unresponsive. My upstairs level got incredibly hot - up to 88 degrees. Josh was able to unclog the condensation line, he flushed it out twice just to be certain the blockages were gone. He walked me through the specifics of getting my A/C units serviced (cleaned) because they are extremely filthy which isn’t helpful/ causing poor air intake. Josh also kindly replaced my upstairs air filter in the attic (I never knew where it was - older home) and he showed me how to change it myself next time I’m due for a new filter! I’m relieved and grateful, thanks Josh :)

The Dayco Team performed their yearly heating maintenance for my downstairs and upstairs furnace systems. The team was very thorough and detailed any areas of improvement that may be needed without any pushy upsell. I continue to be pleased with their service.
