HOMEOWNER FAQS

Frequently asked questions

Is a larger air conditioner better?

No. Oversizing can cause short cycles, humidity problems, noise, and uneven comfort. Capacity should be based on the home’s actual cooling load.

Should every bid use the same brand?

No. Compare capacity, certified performance, installation scope, controls, warranty, and local service support.
