Energy Efficient Air Conditioners
At O'Brien Heating & Air Conditioning, our Lennox® cooling products use an ozone-friendly, chlorine-free R-410A refrigerant that meets strict guidelines laid out by the U.S. Environmental Protection Agency (EPA). This refrigerant can keep your system cooling effectively, while lowering its environmental impact.
Ultimate Comfort System
Our Ultimate Comfort System is bursting with energy efficient and new technologies that will adjust your heating and cooling temperatures in minor increments to keep a consistent temperature and a very small amount of energy.
First Air Conditioner with 26 SEER Rating
We sell the first air conditioner to earn a 26 SEER* rating which means it’s one of the most efficient cooling systems available. Plus, the XC25 can significantly decrease your monthly utility bills without sacrificing the cool temperatures you want.
Reduce Utility Bills
Living in the Main Line doesn’t have to bring on 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 high efficiency, which can potentially decrease your annual energy expenses.
Dual Fuel Systems
Combining our gas furnace with an electric heat pump creates a dual fuel system that helps increase your systems’ operation efficiency. The gas heat is solely used when it becomes too cold for the heat pump to run efficiently, possibly saving you money and keeping your home cozy.
