Industry Overview
HVAC work is expensive and can be over-quoted when minor fixes would suffice.
⚠️ Watch Out For — Common Upsells
Upsells or issues: sometimes the problem is just the blower resistor (if fan only works on high, for example) but a shop might replace the motor and resistor as a set unnecessarily; charging a lot of labor if it’s actually a quick job (some are very accessible, others not); using an OEM blower at triple the price of aftermarket without giving option.
Replacing the compressor when the issue is a leak or fuse; Recharging refrigerant without fixing the source of the leak; Adding “cleaning” or “deodorizing” services unnecessarily
❓ Questions to Ask Your Mechanic
“Was it the motor that failed or the resistor/control module?” - Different symptoms: no fan at all vs only high-speed working. Ensure correct diagnosis. If motor is seized or noisy, replacement is valid. Ask if the new motor is OEM or aftermarket and the warranty. Also, “Will you also replace the blower resistor if needed, and is that included?” - If the old motor drew too much power, it might have blown the resistor, so clarify what's included to avoid a second labor charge.
Did you check for refrigerant leaks before recommending part replacements?; Is this part truly failed, or is there a simpler repair option?
