Frequently asked questions
Why the big price range?
The difference between Good and Best is 5–7 SEER points of efficiency and 15+ dB of sound reduction. In Antelope Valley heat, higher SEER2 pays back in 5–8 years through lower SCE bills.
Is a 4-ton the right size for my house?
Rule of thumb: 4-ton fits 1,800 – 2,400 sq ft in the Antelope Valley. We run a Manual J load calc on every quote — sizing by square-foot rule of thumb is a leading cause of comfort complaints.
Does the price include the old unit removal?
Yes. Every DC Air quote includes haul-away, refrigerant reclaim (EPA compliant), and disposal.
