My AC was working fine until I had Nazzaro & Sons plumbing perform a routine maintenance check. Less than one week later my AC was not working and I was refererred to Gordon by Nazzaro. I explained the situation and Gordon added $685 worth or refrigerant but never performed a pressure check to see if there was a leak. Four days later I had no AC again. Gordon returned and performed a pressure check and concluded I did have a leak in my furnace exchanger coils which Nazzaro had cleaned. My system was almost 20 years old and I decided to replace my furnace and AC. Gordon said he would credit the $685 of wasted refrigerant to the price of a new system but his quote was considerably more than others who said the cost of refrigerant was included with all new systems anyway. I won't be using Nazzaro & Sons or My Dear Watson in the future

Their response is very good and that really helps when one is looking for someone who can cater to the issue and fix it as quickly as they did. Thankyou My Dear Watson Plumbing, Heating & Cooling!

Was able to get a quick appointment for my leaking hot water heater. He explained the process and had the water heater changed out in very little time. Very professional.

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.
