  • Personal Client Care

    Just wanted to take a moment and recognize the outstanding service I just received from Harriett’s Oil in Medford. After being without air conditioning for several days and working thru several contractors, I contacted Harriett’s to look at my problem and had them provide a repair proposal. During the course of the repair some unforeseen conditions arose that forced a delay and additional cost to the repair. Bob Harriett got involved personally and provided a portable cooling unit to get us thru this current heat wave, expedited the repair, and honored the original proposal. In today’s world of email and call backs, it is a pleasure to do business with a company that truly cares about their clients.

  • Emergency Response

    You are the best!  You came on a Sunday 30 minutes after I called.  Thank you so much!

    Barbi A, Browns Mills
  • Energy-Saving Installation

    Thank you again for all of the work that Harriett’s did on my heating/air conditioning/energy-saving work.  Even in all of this heat, the air conditioner hardly runs.  The attic fan turns on early in the day and does most of the work.  I can keep the thermostat at 73-75°, and it’s very comfortable.  All this in addition to my monthly fuel budget figure going down $40!

    Carol S, Medford
  • Conversion to Gas Heat

    From your sales department to your office associates to your installation technicians, it was a great experience.  We love our gas heat!

    Antonelli/Sprague, Hammonton
  • Give Other Businesses Lessons?

  • Harriett’s Field Techs the Best!

    I retired from the NYPD after 30 years,  where I experienced a LOT of bad people.  I’ve never experienced such a fine group of human beings as Harriett’s has.  They’re decent people and knowledgeable about the equipment they service.

    James G, Medford Lakes

    Your technician was very courteous, and he left everything neat and clean, which is greatly appreciated!  He also explained what went wrong and repaired the problem.  Harriett’s is awesome! Harriett’s has been taking care of our water since we moved here in 2003.  Your tech is respectful, courteous, very knowledgeable and professional.  He is even respectful of customers’ property – he removed his shoes before entering my kitchen!  I wouldn’t have anyone else looking after our water!
