Heating and cooling your home can represent as much as 44% of your utility bill.* With high efficiency ratings and innovative, industry-leading technology, Lennox® home comfort systems can go a long way toward reducing these costs.
When selecting a new system, pay close attention to the SEER rating of the air conditioner and AFUE of the furnace. The higher the SEER or AFUE, the higher the savings.
Beyond efficiency ratings, other factors to consider are:
- Maintenance You can ensure your system operates at peak performance by scheduling annual maintenance checks.
- Zoning A zoning system can drastically lower your heating and cooling costs. With zoning, you no longer have to pay to heat or cool areas of your home that are rarely used.
- Programmable Thermostats According to the Department of Energy, a programmable thermostat can reduce your heating costs by up to 35% and cooling costs by up to 25%.
