Heating & Air Conditioning Installation, Maintenance & Repair

Having a home that’s always the right temperature is essential for staying comfortable when the weather outside fluctuates. We can help you achieve the perfect temperature in your home year-round with our heating and air conditioning services.

Don’t suffer from a house that’s too hot or too cold. If your furnace, boiler, heat pump or air conditioner isn’t performing well and is leaving you sweating or chilly, Sobieski can help.

Maintaining your HVAC system with regular maintenance is key to keeping it running effectively and efficiently.

  • 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.
