Review by in Medford, MA
Project: Repair an Oil Fired Boiler or Radiator Heating System
We just needed the nozzle replaced on my oil burner. Simple repair, but you almost have to have a repair guy do it if you need it done ASAP. The repair man that came out was friendly and knowledgeable and we now have heat again! We will be getting a quote from them to put in our new system in the spring. My advice is to not let your oil run out like we did, but if you do and you need your burner repaired, these are the guys to do it.

I had to have central A/C unit relocated while a new patio was installed. Prendergast was great - extremely responsive and helpful. They did it sooner than anyone else could and for much less than some of the other quotes I got.

Review by in Watertown, MA
Project: Repair an Oil Fired Boiler or Radiator Heating System
I had an odd problem with one (of seven) zones of heat in my house not working properly. I had called the company that installed my heating system (gas/forced hot water) and they'd come out twice, charged me twice, and not been able to fix it. Decided to try someone else and Prendergast was the only company to respond to my Home Advisor search (I guess most companies don't want to deal with diagnosis and would rather just service, install, or repair). Tom called me, got the details of what wasn't working, diagnosed the issue (stuck pressure relief valve) over the phone and gave me very detailed advice on how to fix it myself. Problem solved, and for free! Can't recommend them highly enough, and will definitely be calling them for any future work

They came out on time and repaired the cracked central ac unit tubing. They know their stuff and pleasant to work with. I would highly recommend them.

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.
