Did an ok job, but spilled oil all over my floor - the room smelled like heating oil - had to air it out for like 3 days. Also when pouring excess oil back to my tank, spilled it all over the tank and did not even clean it up. Kind of disappointing? Update: 2 months later one of the hoses that the technician had to disconnect to perform the tune-up of my oil furnace started to leak. I called the company to have them come in and fix it. They told me that it will cost me $175 service call fee plus the cost of parts and labor. The leak was not there before Phase II technician touched the unit. It is obviously the result of them working on the unit and should be covered and free of charge. This is definitely NOT the way they should conduct the business. DEFINITELY DO NOT RECOMMEND THIS COMPANY!!! TERRIBLE SERVICE AND HORRIBLE QUALITY OF WORKMANSHIP!

Wonderful experience with a very skilled technician to replace a 4 zone thermostat that is no longer available. Our problem was resolved in a timely manner and we were kept informed every step of the way.

Robert is fantastic! You can see that he takes great pride in his work! He is a truly a pleasure to deal with. He did a great job of removing an old oil burning furnace and installing a new gas furnace. Thorough, neat, professional - and friendly, too! I highly recommend Phase II Development!

Robert G. is a true Professional. We had a furnace down situation due to failed control board. Robert came on time and performed a diligent diagnostic and explained me the problem. His price for repair was very reasonable and issue been fixed in a couple of hours. Job was done in very a professional matter. I will definitely recommend Robert to my friends and neighbors. Well done Robert!!

For the work that was done, the owner charged me too much. I will get an estimate next time, before the job is done!

Robert did a phenomenal job. He showed up on time and came well prepared to handle the repair to my burner. He took the time to explain what he was doing and how to prevent any issues from reoccurring before my next maintenance is due. Would definitely use Phase II Development in the future.

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)
