Very skilled and hard working professionals

This company is really organized. They had everything they need with them - so many boxes. When they said the workers were trained that was an understatement. They didn't need to read directions to install and wire very complex heat pump furnace install. And hard working arriving early on only stopping for lunch. Never charged anything extra even if the job had unexpected expenses or permits. Would and will highly recommend to anyone.

Very professional team and quality work

The team installed a Lennox Central Air system and a Mitsubishi ductless heat pump for a house I own in Nazareth, PA. They were very punctual to get the work started, they worked very efficiently to get the work done on time, and were very helpful in showing us how to use the systems. They were also very quick with the rebates paperwork and I got one of the checks already! I think the price was fair for the equipment and the quality of the work performed. It's difficult to compare prices because each installation has some unique factors. The installation was to replace an out of date unit that was over 20 years old.

Great service and competitive prices.

I did quite a bit of investigation and analysis when I had my heating system replaced and when having central air installed. I did a detailed comparison of the bids and solutions offered and then selected Sullivan over three other vendors. I have not been disappointed with that decision and have nothing but good things to say about my experience. Sullivan sales, technicians, and installers were all professional and the biggest reason I went with Sullivan was that I felt strongly that they would take care of my HVAC needs while being honest and trustworthy. I was especially impressed that they did everything possible to ensure that every little detail of my installation was taken care off from removal of the old system to final clean up. I intend to get a yearly maintenance contract with Sullivan and look forward to building a long term relationship with them. Based on my recent experience, I would not hesitate one bit to recommend Sullivan as a great company to deal with.

WARM AT LAST!

This is the first time in 12 years we've been in this house that I am actually warm in the winter! I am getting so much done now that I don't have to run upstairs under the covers when it's cold! And the customer service is excellent!
