* SEER, or Seasonal Energy Efficiency Ratio, measures the cooling efficiency of your air conditioner or heat pump. A higher SEER rating means greater energy efficiency and more savings for you and the environment.

** Annual Fuel Utilization Efficiency (AFUE) measures how efficient the appliance is in converting its fuel’s energy into heat over the course of a year.

  • 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 minimal amount of energy.
  • Lennox Energy Efficient Air Conditioners
    At Kapaun & Brown Inc., 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 harm done to 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 you can find. Plus, the XC25 can substantially lower your monthly utility bills without sacrificing the comfort you want.
  • Reduce Utility Bills
    Living in Marshalltown doesn't have to necessitate outrageous 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, which can potentially decrease your annual energy expenses.
  • Dual Fuel Systems
    Connecting our gas furnace with an electric heat pump creates a dual fuel system that helps increase your systems operation efficiency. The gas heat is only 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.
