The Leslie Heating & Cooling guys were great. They were polite, answered all questions & gave more info than requested. They knew what they were doing, worked quickly & left the system better than they found it. They were a credit to their company.

Leslie hearing and cooling is a phenomenal company they have serviced my furnace every year and it amazes me how polite,professional, and promt they are. Today we had the opportunity to be serviced by Anthony H. And as usual I was very happy with him. Great job Anthony H

My two-year-old furnace seemed to be leaking water so I called Leslie Heating and Cooling. I received same-day service and repair with a thorough explanation of what created the problem.

Pawel M., our service specialist was extremely knowledgeable for a very complicated issue with our new Lenox furnace. I was so pleased with his explanation and attention to detail. Outstanding job!

I'm new to Leslie H&C and so far all is well. When I called Carrie was very efficient with informing me about Leslie and scheduling my appointment that fit my schedule. My service specialist was Sean who new his stuff and when he left I felt good that I will have no problems this winter in keeping my house warm and my humidifier working properly.They are a local company, which I like and I also like their logo too.

Peter K. and Mark N. were fantastic. Very knowledgeable and professional. They cleaned up when they were done and walked me through the operation.

Miguel was great! Very personable and knowledgeable about our furnace/AC unit. He took me step-by-step through his inspection/cleaning and informed me of next steps to take for a more efficient, cleaner air system. 5 stars!

Miguel did an excellent job servicing our furnace. He was punctual, friendly, and professional.
