Do I really need duct cleaning?
Probably not. EPA and CDC both say duct cleaning is not a routine maintenance service - it's only worth doing when there's a specific reason. Those reasons are: visible mold growth inside ducts, infestation (mice, squirrels, insects), substantial debris from a major renovation, or contamination from water damage. If your filter is clean, your system is sealed, and your IAQ symptoms are nothing specific, duct cleaning is not going to fix anything. We'll tell you that on the phone.
How often should I have ducts cleaned?
There's no schedule. Duct cleaning is not like an oil change. The right answer is 'when there's a reason' - which for most NE Ohio homes is never, or maybe once after a major renovation. Skip any contractor who tells you you should clean ducts every X years. That's the script that pays for the $99 promotion.
What are the signs my ducts actually need cleaning?
Visible mold inside the ductwork when you pop a register cover (not just dust - actual mold growth). Evidence of rodents or insects in the ducts (droppings, nesting material, dead pests). Heavy debris after a renovation - drywall dust, sanding residue, demolition dust pulled into the return. Strong musty or chemical odor that doesn't go away after filter change and source check. If you're not seeing one of those, you almost certainly don't need it.
What should real duct cleaning cost?
Call (330) 469-6701 for AKHC's current rate. What we will tell you: real NADCA-process whole-system cleaning is multiple-hour work with serious equipment - a negative-pressure vacuum collection unit and mechanical brushes that agitate every duct run. If you're being quoted $79, $99, or $129 for 'whole-house duct cleaning,' it's not actually that. It's a high-pressure compressor through one or two registers and a sales pitch when the tech walks the house. The honest pricing tier for the real work is many multiples of that, and we won't quote a number without seeing the system.
Are the $99 duct cleaning specials a scam?
Same playbook as the $49 AC tune-up. The number gets the truck in the driveway, and the tech walks the house finding reasons to upsell. Sometimes the upsell is more duct cleaning ('we found mold in your main trunk, that's an extra $1,200'), sometimes it's a new air handler, sometimes it's a 'whole-home sanitization' package. The $99 work that does happen is a compressed-air gimmick that doesn't meaningfully clean anything. NADCA, the actual industry association for duct cleaners, has published warnings about this exact pattern.
Should I do a chemical fogging or 'sanitization' treatment?
Generally no. EPA has not approved most chemical biocides for use inside HVAC ducts - the chemicals can off-gas into the living space, and most aren't necessary if the actual cleaning is done right. If there's documented mold, the answer is mechanical removal (the NADCA process) plus fixing the underlying moisture problem - not a chemical that masks it. If a contractor's primary recommendation is fogging or chemical treatment, that's a red flag.
My ducts are leaky - do I need cleaning or sealing?
Sealing is almost always the bigger win. Average residential ductwork loses 20-30% of conditioned air to leaks at joints, takeoffs, and registers. Aeroseal or manual mastic sealing recovers that lost air, raises efficiency, and reduces dust pulled in from unconditioned spaces (attics, crawlspaces). If your ducts are leaky, fix the leaks first - then you'll know whether cleaning is still needed. Cleaning a leaky duct system is throwing money at the wrong problem.
My tight modern home feels stuffy - is duct cleaning the answer?
No - that's a ventilation problem, not a duct cleanliness problem. Homes built since 2000 (Howland, Boardman, Canfield, Cortland) are tight enough that they don't naturally exchange air with the outside, so CO2, moisture, and VOCs build up. The fix is an ERV (energy recovery ventilator) or HRV (heat recovery ventilator) per ASHRAE 62.2 - mechanical fresh-air exchange that doesn't kill your heating/cooling efficiency. Cleaning the ducts won't change the air you're already breathing.
