If you’ve never had your air ducts cleaned before, figuring out how to choose an air duct cleaning company can feel like guesswork. Every website says “professional” and “affordable,” but those words don’t tell you much. After years of working in homes across Port St. Lucie, Fort Pierce, and the rest of the Treasure Coast, we’ve heard the horror stories — companies that quote one price on the phone and charge triple once they’re in the attic, or crews that show up with a shop vac and call it a duct cleaning. Knowing what to ask upfront saves you money and protects your HVAC system.
Start With Pricing Transparency
This is where most bad experiences begin. A company that won’t give you a real number over the phone, or one that quotes a suspiciously low “whole house” price, is usually setting up an upsell once they’re inside your home.
Ask directly what the base price includes and what would push the cost higher. For reference, air duct cleaning starts at $245, and dryer vent cleaning runs $125 for a single-story home or $175 for a two-story home — those numbers should be in the same ballpark no matter who you call. If a quote is way under that, ask why. If it’s way over, ask what’s different about their process. A price that’s dramatically lower usually means fewer vents are actually being cleaned, a shorter visit, or a follow-up call once the technician “discovers” more work needs to be done.
- Get the price in writing or via text/email before the appointment
- Ask if the quote is per system, per vent, or a flat whole-home rate
- Ask what triggers an additional charge (extra returns, mold, rodent nests, etc.)
- Confirm there’s no “trip fee” or inspection fee tacked on separately
Confirm They’re Licensed and Insured
This one matters more than people realize. Technicians are climbing into attics, working around your HVAC equipment, and sometimes accessing tight crawlspaces. If something gets damaged — a bent duct, a cracked vent cover, a scuffed wall — you want to know the company carries insurance to cover it, not that you’re stuck arguing over who pays.
A legitimate company won’t hesitate when you ask, “Are you licensed and insured?” It’s a normal question and any business that’s been doing this for a while expects it. Air Duct Cleaning PSL is family-owned and operated, licensed and insured, and owner Jeff built the company on answering that question before customers even have to ask it.
Ask What Equipment They Actually Use
This is the question that separates a real duct cleaning from a quick vacuum-and-go. Ask specifically what tools they bring — negative air/vacuum systems, rotary brushes, agitation devices for the supply and return lines. A company that can’t describe their process in plain terms probably doesn’t have much of a process.
It’s also fair to ask how long the job typically takes and what happens vent by vent. A thorough cleaning means every supply and return is opened, agitated, and vacuumed back to the main trunk line, not just blown out at the register. Ask whether they inspect the system before starting — noting existing damage, previous repairs, or areas that need extra attention — and whether they’ll walk you through what they found afterward. If someone tells you they can do a whole house in twenty minutes, that’s a red flag, not a selling point.
Look for Before-and-After Photos and Real Reviews
Any company can say their work makes a difference. Photos prove it. Ask if they document the job with before-and-after pictures of your actual ducts — not stock photos on a website, but real shots from real jobs. It gives you something concrete to compare and holds the crew accountable for doing thorough work.
Reviews matter too, but read a handful, not just the star rating. Look for comments that mention punctuality, communication, and whether the final price matched the quote. We’re proud that our reviews reflect that consistency — we sit at 5.0 stars across 47 Google reviews, and we’d rather earn the 48th the same way.
A Few More Questions Worth Asking
- Do you clean dryer vents too, or just HVAC ducts? (A clogged dryer vent is a well-known cause of home dryer fires, so this shouldn’t be an afterthought.)
- Can you offer same-day or next-day service if I need it?
- Do you offer sanitizing or air purification add-ons, and are those optional?
- How long have you been serving this area specifically?
- Will the same crew that quotes the job be the one that shows up to do it?
Trust Your Gut, Then Verify It
At the end of the day, choosing an air duct cleaning company comes down to two things: does their answer match what you asked, and does their price match what they promised. A company that answers plainly, shows you their equipment, and backs up their pricing isn’t hiding anything. If a company dodges a straight question or gets vague about cost, that’s your answer — move on to the next quote.
