The cost to install a UV light in an HVAC system is provided as an upfront quote after we assess your equipment, because price varies by UV technology and installation access. Most differences come from choosing a coil-sanitizing lamp versus an in-duct purifier and how straightforward it is to mount and power the unit. We regularly install and service UV air sanitizers for homeowners throughout the Rockville area. Technicians often place coil-sanitizing lamps to shine directly on the damp evaporator coil, where microbes tend to grow. Current savings may apply, such as 15% Off UV Air Purification System (conditions apply).
If you want a precise number, these factors determine it:
- UV device type and number of lamps
- Access to the coil or duct and any needed bracket or panel work
- Availability of a nearby electrical connection
- Any IAQ add-ons requested together (e.g., filter upgrades)
Schedule an in-home evaluation to confirm the right UV option and get a firm price before any work begins.
