Frequently Asked Questions
Why is proper refrigerant level important?
Refrigerant is the lifeblood of your AC system. It absorbs heat from your indoor air. Low or leaking refrigerant can’t absorb enough heat, causing the compressor to shut off prematurely. Regular checks are crucial for maintaining the right refrigerant level. For more information, consider reading The Comprehensive Guide to Ductless AC Installers in Florida.
How does a dirty air filter affect my AC?
A clogged air filter restricts airflow over the evaporator coils, causing them to freeze. This puts additional strain on the compressor, leading to frequent shutdowns. Regularly cleaning or replacing the air filter is a simple yet effective way to prevent this. For detailed guidance, you might find How Often Should Air Ducts Be Cleaned: Need to Know Guide helpful.
