Energy Efficient Air Conditioners
At C-N-O Comfort Zone, our Lennox® cooling products use an ozone-friendly, chlorine-free R-410A refrigerant that meets strict guidelines put forth by the U.S. Environmental Protection Agency (EPA). This refrigerant can help your system cool effectively, while lowering its environmental impact.
Ultimate Comfort System
Our Ultimate Comfort System is full of energy efficient and new technologies that will adjust your heating and cooling temperatures in minor increments to maintain a consistent temperature and a very small amount of energy.
First Air Conditioner with 26 SEER Rating
We offer the first air conditioner to achieve a 26 SEER* rating which means it’s one of the most efficient cooling systems on the market. Plus, the XC25 can significantly reduce your monthly utility bills without sacrificing the comfort you want.
Reduce Utility Bills
Living in Saint Peters doesn’t have to mean expensive utility bills. In fact, a number of our HVAC products have earned the ENERGY STAR® label and high SEER* or AFUE** ratings because of their energy efficiency, which can potentially reduce your annual utility expenses.
Dual Fuel Systems
Connecting our gas furnace with an electric heat pump creates a dual fuel system that helps enhance your systems’ operation efficiency. The gas heat is solely used when it becomes too cold for the heat pump to run efficiently, which could help you save on your energy expenses and keep your home cozy.
