    Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system.

    I hired RJK Mechanical to clean my Air Ducts and Dryer Hose. Chad and Jamey did a great job! They were very patient and informative while I asked them many questions on how the Duct system works and how to avoid re-contamination of pet related allergens in my home while other companies clean my home for a move-in. I would also like to thank Will for be very responsive, informative and helpful. This is the most customer friendly company that I have ever dealt with. Thank you for having the best staff. I would highly recommend this company.

    Responsive service to replace a Furnace AC unit after mine died when temperatures were dipping into the teens. They took the time to make sure they got the right unit for the job; my old furnace was oversized. I had heat after 1 day, then they followed up the next day for a final walk through to assure everything was correct and complete. Fair pricing. Great value.

    I called RJK early in the morning and they reached out to me within 10 minutes. Over the phone they are professional and have a keen sense of urgency to help you. They had service out to my home in two hours and repaired my A/C within one hour. RJK provided me with complete information about my issue and how they were going to remedy it. Very professional, competent and efficient work. Very happy.

    Kevin returned my call promptly. He gathered as much information as he could over the phone to try and see exactly what was needed. He scheduled the appointment that was convenient to my schedule. He showed up early which was greatly appreciated! He serviced the a/c and explained everything that he did. Kevin is honest and trustworthy. I will definitely use him in the future!

    5.0 Michael P. Whitehouse Station, NJ

    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
