I wanted to say a few things about this company. My other company sold to Dayco and this is my experience with the HVAC department. I called them because my upstairs unit was making a strange noise. Dakota came out and found the problem. He recommended what was needed and gave me an estimate. He was very professional. Later I spoke with Lane the service manager to ask a few questions. He was extremely helpful and also very professional. So, I will say that my first experience with Dayco was a very positive one. I would recommend anyone to give them a call.

Once again we had technician Alex Cruz perform our biannual maintenance as cold weather starts. As always Alex is very professional and straight to task. He provided updates on our system and we discussed maintenance activity. We are very satisfied with the service work performed by Alex

This is a new company for me. I couldn’t be happier. They showed up promptly and did a great job for the regular maintenance. When I’ve had a problem later and call them about it, they were all over it. The technician showed up promptly at my house on a Saturday and quickly got my furnace running again. They went the extra mile to get this done and I would definitely recommend this company.

Dean and his team did in excellent job in installing my NEW HVAC system. I had been nursing my old system for the last couple of years. I finally went to the most trusted HVAC company that have worked with for years. The new system chills my first floor down in minutes. I should have done this sooner. Thanks for the all the folks that did the work and the professional staff in the front office and Sales.

Response from Company:

Thank you so much for your thoughtful review! We're thrilled to hear you're loving your new HVAC system and that it's already making a noticeable difference. Dean and the team, along with our office and sales staff, truly appreciate your continued trust in Dayco. We're grateful to have you as a longtime customer!

Went well. The attic stairs we’re broken while removing / installing new furnaces. Dayco without any delay ordered new stairs to be installed. We had an issue with not using material to cover hardwood floors and did get some small scratches. We did review this complaint and they did offer to send a flooring co to repair

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
