* 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 very small amount of energy.
  • Lennox Energy Efficient Air Conditioners
    At Herman Allen Plumbing, Heating & Cooling, 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 achieve a 26 SEER* rating which means it's one of the most efficient cooling systems on the market. Plus, the XC25 can measurably reduce your monthly utility bills without sacrificing the comfort you want.
  • Reduce Utility Bills
    Living in Greater Richmond doesn't have to mean 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 reduce your annual utility expenses.
  • Dual Fuel Systems
    Pairing 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 could help you save on your energy expenses and keep your home cozy.
