4.5 Mark K. Melrose, MA

Denny did an excellent job on my ancient heat pump system. Would call him again.

5.0 Evelyn M. Salem, MA

Prompt, efficient & very reasonably priced. They had to drive back to Beverly to get the specific filter I needed for a humidifier - and they did not charge me for that time.

5.0 Sarah G. Salem, MA

Denny was very quick to respond and help us. The work was done professionally and quickly. Would call again.

5.0 Steve P. Rowley, MA

Very fast & professional service. Woke up on a 93 degree day to my a/c not working, went on to home advisor & within 3 hours my a/c was up & running again. Nice to have a technician actually have the parts in his truck & be able to get there the same day. Also cleaned my coils on the condenser.

5.0 Brian M. Beverly, MA

Flexible and accommodating, highly recommend and will be using in the future.

5.0 Angie O. Danvers, MA

Very professional, great job, extremely thorough. Would highly recommend.

5.0 Mark P. Newburyport, MA

Liked working with Denny very much. He was friendly, and showed up when he said he would. He was also able to schedule the appointment for the next day which was helpful.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
To find more licensing information for your state, visit our Licensing Requirements page.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
