About Us

Robert Theiss service truck Hi! My name is Robert Theiss owner/hands on operator of R & N Heating & Cooling Inc. located in Massapequa, NY. Iíve been in the heating and air conditioning business for over 40 years. Most recent I worked in the Wantagh area for a local oil company as a hands on Installation & Service Manager for 14 years.

I decided to venture out on my own, and offer people an honest, reliable Owner/Operated alternative to larger companies who do not provide the personal touch that I believe most people are looking for.

I jokingly say over my 40 years career I have worked on mansions in Montauk, skyscrapers in Manhattan and pretty much everything in between. Given the opportunity I would be happy to apply my experience and skills to any heating & air conditioning needs you may have.
