Lennox Ultimate Comfort System
Our Ultimate Comfort System is packed with energy efficient and innovative technologies that will adjust your heating and cooling temperatures in tiny increments to maintain a consistent temperature and a very small amount of energy.
Lennox Energy Efficient Air Conditioners
At Hammack Service Company, 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 the impact on the environment.
Lennox: First Air Conditioner with 26 SEER Rating
We offer the first air conditioner to earn a 26 SEER* rating which means it’s one of the most efficient cooling systems you can find. Plus, the XC25 can measurably decrease your monthly utility bills without sacrificing the comfort you want.
Reduce Utility Bills
Living in Richardson doesn’t have to necessitate outrageous 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 reduce your annual utility expenses.
Dual Fuel Systems
Combining our gas furnace with an electric heat pump creates a dual fuel system that helps improve your systems’ operation efficiency. The gas heat is used only 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.
