Fifty Percent Rule
When the cost of repairs approaches 50% of the value of your heating or cooling system, it’s generally time to replace the system.Other Rules of Thumb
Even if needed repair costs aren’t quite as daunting as 50%, you might want to replace your system if it’s more than 12 years old or you’ve had a history of problems with it. Also, it might be worthwhile to take advantage of one of several opportunities:- Convenience – When you purchase a new system, you can avoid the hassle of unexpected repairs down the line, and you don’t have to sit around uncomfortable while waiting for parts.
- Lower utility bills – A high-efficiency home comfort system from Lennox can save you hundreds of dollars each year in energy costs, compared to an older system.
- Energy tax credits – You can recover up to 30% of the cost of select high-efficiency systems in the form of tax credits.
- Friendlier refrigerant – Due to growing environmental concerns, the U.S. federal government has mandated that all HVAC manufacturers phase R-22 refrigerant-based equipment out of production. In response, Lennox now mainly manufactures cooling systems with R-410A, a U.S. EPA-approved, chlorine-free refrigerant.
- Warranty Assurance – If you have an older outdoor unit that needs repair, but you’re not ready to replace your indoor air handler or furnace, a dry-charged unit may be a cost-effective solution. It allows you to avoid the costs of ongoing repair, while also giving you a brand-new outdoor unit backed by a 5-year Limited Warranty.
- Enhanced comfort – Advanced technologies that improve energy efficiency also enhance your comfort, so you can enjoy more even temperatures, better humidity control, and a constant flow of conditioned air.
- Improved air quality – Better humidity control means a reduced potential for mold and mildew growth. Lennox home comfort systems are also available with Healthy Climate®filtration, which minimizes the impact of indoor pollutants.
