  • I am a retired superintendent, and I have dealt with many people of different fields. I found Sobieski Services, Inc. to be very professional. The people who did the installation were very well-mannered and professional. I oversaw their work from salesman to workman.

  • Sobieski replaced my air conditioning unit. It went very smoothly! They were on schedule, on time, and there were absolutely no issues. They were very professional!

    Jeffrey S., Philadelphia, PA
  • I have worked with different contractors before, and they do not compare to Sobieski Services. They are very professional and a great organization; everyone from sales to the technical people work as a team. They were great with keeping in touch with me by returning each phone call on time.

  • Technician was friendly and knowledgeable. After fixing my Heat Pump, and speaking with him throughout the day, I would have gladly invited him over for dinner. Service was great and things are working as they should.

  • I received a courtesy call asking if my technician could come earlier than the scheduled time. He greeted me at the door with a smile, put booties over his shoes to keep my floor clean and explained what he was planning to do.
