enjoy improved comfort right now with a full line of products utilizing

You may not realize it, but your existing indoor weather system is an endangered species. That's the result of the 1990 Clean Air Act and the internationally binding Montreal Protocol. These documents call for an international phase out on future manufacturing of the refrigerant R-22, which is currently used in most air conditioning and heat pump systems.


According to current government regulations, the product HCFC will be reduced by nearly one-fourth by 2004. That means all R-22 products will eventually need to be replaced by products utilizing a chlorine-free refrigerant such as Puron.


Marks' Heating & Air Conditioning, Inc. is taking a leadership role today by offering you a full line of environmentally sound air conditioners, heat pumps and fan coils.
