How can I tell it’s time to replace my air-conditioning system?
If your unit is over 10 years old, needs repairs more often, or your energy bills keep rising even after proper maintenance, it’s usually wiser to invest in a modern, high-efficiency model. New systems offer better comfort while using significantly less electricity.
What advantages come with choosing a high-SEER, ENERGY STAR®-certified unit?
High-SEER, ENERGY STAR models deliver the same cooling with less power, lowering utility bills and reducing your carbon footprint. They also tend to run more quietly and maintain steadier indoor temperatures thanks to advanced compressors and variable-speed fans.
My current system uses R-22 (HCFC-22) refrigerant. What should I expect when I upgrade?
R-22 is being phased out under U.S. environmental regulations. Replacing your system lets you move to eco-friendlier refrigerants such as R-410A or R-32, which protect the ozone layer and meet today’s efficiency standards.
What best practices ensure an efficient, code-compliant installation?
Your contractor should:
Use Manual S to match equipment to the calculated load.
Follow Manual D to size and seal ducts for proper airflow.
Verify static pressure, refrigerant charge, and condensate drainage.
Leave clear access for future maintenance and document all work to keep the manufacturer’s warranty valid.
How can I extend the life and efficiency of my new AC system?
Replace or clean the air filter regularly (more frequently if you have pets or high dust levels), keep the outdoor condenser clear of debris, and schedule professional inspections at least once a year. Consistent upkeep preserves efficiency, prevents breakdowns, and protects your investment.
