Get the scope before the appointment
- How many supply vents are included?
- Are return ducts included?
- Are main trunk lines included?
- How many HVAC systems are included?
- Is the advertised amount the total price or a starting price?
- What services can increase the price onsite?
Watch for a scope switch
The problem is not an inexpensive coupon by itself. The problem is when the service described before the appointment is materially different from the service presented after the technician arrives. Ask for the expected total and any common add-ons in writing.
Do not buy fear
Be cautious when a salesperson uses urgent health claims, says an expensive chemical treatment is mandatory without a clear reason, or cannot show you the condition being discussed. Ask for evidence and a written explanation of the proposed work.
Sources and methodology
We use current consumer cost references for price ranges and primary EPA or NADCA guidance for safety, cleaning scope, and homeowner precautions when available. Published prices are planning benchmarks, not contractor quotes.

Price the actual job, not the headline number.
Use your vent count and ZIP to build a planning range, check researched local benchmarks, then compare nearby contractor options.
