Customer Testimonials
Mr. Chip was incredible. They came to my apartment in under 24 hours during busy time after Hurricane Ida. Replaced my A/C motor in under an hour, and did not try to add any unnecessary services. Super nice & works hard! Thank you Mr. Chip!!! Will be using you for all my A/C needs from now on.
