Frequently Asked Questions
How do I know if I need AC repair or replacement?
If your AC is over 10 years old, breaks down frequently, or isn’t cooling efficiently even after repairs, replacement may be more cost-effective. A professional inspection can help you decide the best route based on the condition and age of your system.
​
Can I run my AC if it’s making weird noises?
It’s not recommended. Strange noises like banging, rattling, or screeching could indicate serious internal damage. Continuing to run the unit could cause further harm. Turn it off and call a professional to inspect the issue before it gets worse.
