Should I repair or replace my AC?
If it’s over 10–15 years old, needs frequent fixes, or isn’t cooling well, replacement may be smarter. For minor issues, a repair can do—but major problems on older units often aren’t worth the cost.
How often should I service my AC?
We recommend servicing your AC at least once a year—preferably before summer.
What brands do you install or repair?
We handle all major brands including Lennox, Carrier, Goodman, BladeX, Trane, and more.
