• System requires increasingly frequent repairs
• Repair costs approaching 50% of replacement cost
• Parts becoming difficult to find for older models
• Overall declining performance and reliability

Efficiency & Cost Problems:

• Dramatically increasing summer electric bills
• New high-efficiency systems would pay for themselves through energy savings

High-Efficiency Air Conditioning Options for Littleton Homes

Understanding SEER Ratings SEER (Seasonal Energy Efficiency Ratio) measures air conditioner efficiency. Higher SEER means lower operating costs:

• Minimum Efficiency – 14 SEER (required for new systems)

A 16 SEER system uses approximately 13% less electricity than a 14 SEER system. Over the life of the equipment, higher efficiency can save thousands in energy costs.

Variable-Speed AC Technology Variable-speed air conditioners offer superior comfort and efficiency:

• Compressor adjusts output from 25-100% capacity
• Runs longer at lower speeds for better humidity removal
• More consistent temperatures throughout home
• Quieter operation than standard on/off systems
• Significantly lower operating costs
• Better air filtration from increased air circulation

Two-Stage Air Conditioners Two-stage systems offer better performance than single-stage:

• Low stage runs most of the time (60-70% capacity)
• High stage for extremely hot days
• Better humidity control than single-stage
• More even temperatures
• Lower energy costs
• Quieter operation
