Common Questions

What SEER should I buy for Spokane?
16–18 SEER is the sweet spot — each 2 SEER improvement cuts cooling energy cost roughly 10%. Going higher is rarely justified for Spokane's moderate cooling season.
Can I just recharge my AC refrigerant?
Refrigerant does not get consumed — low charge means a leak. Find and repair the leak, then recharge. Repeated recharges without repair damage the compressor.
Does my R-22 system need to be replaced?
Not necessarily, but recycled R-22 is expensive. If it leaks, the repair economics often favor a new system. If it runs fine, maintain it until it fails naturally.
