Professional air duct cleaning costs vary by home size, duct layout, and contamination level; final pricing is confirmed after an on-site assessment. The biggest cost drivers are how many supply and return vents you have, total duct length, and how accessible the ducts are. As technicians, we often see that sealing obvious duct leaks lowers dust and improves airflow more than a one-time cleaning. We offer indoor air quality solutions and air duct sealing, with findings explained and documented through our Comfort Check report card. Our team serves the Roanoke Valley with maintenance that includes inspection and cleaning steps that support healthier air.
Price commonly changes with:
- Number of registers and returns included
- Type/amount of debris (pet hair, renovation dust, suspected microbial growth)
- Access challenges (attic or crawlspace runs, tall ladders, tight chases)
- Add-on tasks requested (sanitizers, coil or blower cleaning, dryer vent service)
Schedule an inspection and ask for a written scope so you can compare cleaning versus sealing on true, itemized terms. <br/> Updated: 2026-02-25 <br/> Need help in Salem, VA? Call (540) 238-0320 or book online.

Most installations require an in-home assessment, so UV light install costs are confirmed after inspection. Pricing varies by system size, access to the air handler, number of lamps, and any wiring or controls needed. In Roanoke and Rocky Mount, our HVAC team can recommend indoor air quality solutions during a Without Worry Comfort Check and provide a written, fixed quote before work begins.

The cost to install a UV light in an HVAC system varies and is only confirmed after an on-site inspection. Prices change most with lamp type and placement, labor access to the air handler, and any needed electrical work. UV can help with coil cleanliness and certain microbes, but it’s one option among indoor air quality solutions; we also improve IAQ through air duct sealing and routine maintenance that includes cleaning and system tune-ups. Our technicians serve local homes regularly and will size any add-on so it fits the system without hurting airflow.
Common cost drivers your technician will verify:
- Single- vs. dual-lamp assemblies and whether it targets the coil or air stream
- Accessibility of the unit and sheet metal modifications
- Power supply location, switch, and wiring needs
- Brand features, replacement bulb life, and warranty terms
Ask a licensed HVAC pro to evaluate your system and give a written, all-in price before you decide. <br/> Updated: 2026-03-13 <br/> Need help in Cloverdale, VA? Call (540) 238-0320 or book online.

Yes. A nonworking UV bulb is often fixed by replacing the lamp after confirming the unit has power and the safety controls are working. If it still won’t light, a technician should diagnose the power supply and wiring. Wisler offers indoor air quality solutions and can evaluate your system as part of our Without Worry Comfort Checks, which include inspection, cleaning, adjustments, and a written report. We serve Roanoke and surrounding areas.
