Lennox Ultimate Comfort System
Our Ultimate Comfort System is bursting with energy efficient and new technologies that will adjust your heating and cooling temperatures in tiny increments to maintain a consistent temperature and a surprisingly small amount of energy.
Lennox Energy Efficient Air Conditioners
At Oak Grove 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.
Lennox: 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 on the market. Plus, the XC25 can significantly reduce your monthly utility bills without sacrificing the comfort you want.
Reduce Utility Bills
Living in Hattiesburg doesn’t have to bring on expensive utility bills. In fact, many of our HVAC products have earned the ENERGY STAR® label and high SEER* or AFUE** ratings because of their high efficiency levels that can potentially save on your yearly utility expenses.
Dual Fuel Systems
Pairing our gas furnace with an electric heat pump creates a dual fuel system that helps enhance your systems’ operation efficiency. The gas heat is used only when it becomes too cold for the heat pump to run efficiently, possibly saving you money and keeping your home cozy.
