Lennox Ultimate Comfort System
Our Ultimate Comfort System is bursting with energy efficient and cutting-edge technologies that will adjust your heating and cooling temperatures in minor increments to preserve a consistent temperature and a minimal amount of energy.
Lennox Energy Efficient Air Conditioners
At WM J Kraus & Son, 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 the impact on the environment.
Lennox: First Air Conditioner with 26 SEER Rating
We sell the first air conditioner to be rated 26 SEER* which means it’s one of the most efficient cooling systems available. Plus, the XC25 can substantially reduce your monthly utility bills without sacrificing the comfort you want.
Reduce Utility Bills
Living in Keokuk doesn’t have to mean 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 energy efficiency, which can potentially save on your yearly utility expenses.
Dual Fuel Systems
Combining 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 can help lower your energy costs and keep your home more comfortable.
