Frequently Asked Questions
How do I know if I need a new AC unit?
If your system is over 10–12 years old, needs frequent repairs, or can't keep up on hot days, a high-efficiency replacement is usually the smarter long-term investment.
Are ductless mini-splits worth it?
For additions, garages, or homes without ductwork, mini-splits offer efficient zoned cooling and heating with minimal installation disruption.
How fast can you repair a broken AC?
Most AC failures are diagnosed and repaired the same day — we prioritize no-cooling calls during summer heatwaves.
