FREQUENTLY ASKED QUESTIONS
Why does my AC run but not cool my house?
This can be caused by low refrigerant, dirty coils, airflow restrictions, or compressor issues.
Can a clogged air filter cause AC problems?
Yes, a clogged filter can restrict airflow, reduce efficiency, and even cause the system to freeze up.
What should I do if my AC freezes up?
Turn the system off and allow it to thaw, then contact a technician to identify the underlying cause.
Is it normal for my AC to cycle on and off frequently?
Short cycling is not normal and often indicates a thermostat issue, improper sizing, or mechanical problems.
Can outdoor temperature affect AC performance?
Yes, extremely high outdoor temperatures can strain the system, but it should still maintain cooling indoors.
How do I know if my AC needs refrigerant?
Only a professional can confirm this, but signs include warm air, ice buildup, or long cooling cycles.
Should I repair or replace an older AC system?
If repairs are frequent and the system is over 10–15 years old, replacement may be more cost-effective.
Can electrical issues cause AC failure?
