Why we show real prices online
Most San Antonio HVAC companies will give you any number except a price. You call, they send a salesperson, the salesperson sits at your kitchen table for two hours, and at the end you get a number that depends on how badly they need to hit quota that month.
We don't run that play. We're a family — Clint and his three sons — and we don't pay commission on tickets. The price you see here is the price we charge, with the instant factory rebate already applied.
The $500 discount is real — it's our cost of not sending a salesperson to your house. You did the work; we pass the savings on.
