Questions?
The equipment you select for your system will be determined largely by the climate where you live. Warmer climates may include a heat pump and an air handler, while colder climates typically include an air conditioner and a furnace. Yet, a moderate climate may call for a dual-fuel system. A Lennox Comfort Advisor is trained to help you plan a system that will meet your unique needs and solve your specific comfort issues. For more tips, read: Building your Complete System: The Smarter Way to Better Comfort.
By replacing your entire system, rather than just a single component, you get equipment that’s been designed to work together. Because of this compatibility, you’ll enjoy greater energy efficiency and optimized comfort. With the continuing advancement of home comfort technology, equipment is becoming more energy efficient. A new system may offer you substantial energy savings even if your current system is only a few years old.

Start with our dealer locator to find a Lennox dealer near you. Our Premier Dealers are trained to build a solution to meet your needs, have Ultimate Comfort System product knowledge and are experts in equipment installation. Prior to a visit from a Comfort Advisor, we recommend that you spend some time asking yourself ‘How do I want the air in my home to feel?’ and ‘What Does Perfect Air Mean to Me?’. Identifying these needs and goals will help your Comfort Advisor recommend a system that delivers Perfect Air.
A Lennox dealer can give you the best estimate of cost for a HVAC system to meet your needs. Your dealer will evaluate the size and age of your home, your home’s design, layout and ductwork and the local climate. These inputs allow a Lennox dealer to recommend your ideal system configuration, calculate the installation effort and provide you with a quote.
Some things to consider:
- Your heating and cooling system accounts for around half of the energy your home uses each month.
- From financing options to rebates and federal and local tax credits, investing in a new HVAC system is within your reach.
- Our energy savings calculator can help you estimate your savings over the lifespan of your HVAC system.
