We don’t publish a flat price for duct cleaning. A Parrish technician confirms your cost after an on-site inspection of your system. Pricing varies by home size, number of supply/return runs, contamination, and access. Add-ons can change the total, such as duct sealing, AC coil cleaning, UV or HEPA air purification, and condensate drain cleaning. Our licensed, insured team delivers custom IAQ solutions in Fairfax, Reston, and across Northern Virginia.

Pricing for HVAC UV light installation is custom. It depends on your system, duct access, and the specific UV equipment selected. Parrish Services evaluates your home and provides a written price after inspection. Financing is available for larger installs or repairs with approved credit. We also offer whole-home IAQ options like filtration, duct cleaning, coil cleaning, and humidifiers to complement UV lights. Service is performed by licensed, insured technicians across Northern Virginia, including Reston and McLean.

The cost to install a UV light in an HVAC system varies by home and equipment, and Parrish Services provides final pricing after an on-site evaluation. The biggest driver is the UV setup itself (single-lamp coil sterilization vs dual-lamp or whole-home air treatment), followed by how the lamp mounts in your air handler and whether a new power tap is needed. Our Northern Virginia technicians often see price differences based on access to the air handler in homes around The Plains, and tight attic or crawl spaces can add labor. A well-placed coil UV usually targets mold where it starts; whole-home options pair with filtration for broader air treatment.

Main cost drivers include:

• UV type and lamp count
• Mounting location and system size
• Electrical access or added transformer
• Add-ons like filters or air cleaners

Ask for a brief in-home assessment so the UV is sized correctly and placed for real coil coverage.

Yes. In most cases, a UV air purifier can be repaired by replacing the UV bulb. Parrish Services installs and services UV air cleaners and HVAC UV lights, and our licensed technicians can replace bulbs and verify operation. If the light still won’t run, we can inspect wiring, switches, and controls during a maintenance visit. We also offer whole-house IAQ solutions, coil and duct cleaning, and filter programs to help keep air clean in Reston and Alexandria.
