Great job with my air duct cleaning service!
Lisa GriesemerTyree was pleasant and seemed to do a thorough job cleaning our furnace and getting it ready for winter.
Mary JusticeNick and Ryan on the HVAC side were also accommodating to our needs and also installed special fabricated air ducting created by the Johnson team.

Where should HVAC UV light be installed near the evaporator coil?
HVAC UV lights for coil treatment should be mounted in the supply plenum just downstream of the evaporator coil so the lamp has a clear line of sight to the coil and drain pan. This placement targets the damp surfaces where microbes tend to grow and keeps the light from shining into occupied spaces. We install in-duct UV for homes in the Beech Grove area and position lamps for full surface coverage while leaving room for maintenance.
Place the lamp with:
- Direct illumination of coil surfaces and the drain pan
- Minimal shadowing from brackets, insulation, or wiring
- Adequate clearance from plastics and wire insulation susceptible to UV
- A serviceable mounting point for lamp replacement
Always shut off power and confirm orientation before opening the plenum to avoid eye/skin exposure and equipment damage.

How much does it cost to install UV light in an HVAC system?
The cost to install a UV light in an HVAC system is finalized after an in‑home evaluation and free quote because equipment type and placement vary by home and ductwork. Prices shift most based on choosing a coil‑surface UV lamp versus an in‑duct UVC air purifier and how easily we can access ducts and power. For air disinfection, technicians typically place UVC units in the return duct before the filter, and we routinely install these for homeowners near Edinburgh. Whole‑home purifiers integrate with forced‑air systems, while portable units only treat single rooms.
Key factors that set your price:
- Equipment category and capacity (coil UV vs in‑duct UVC purifier)
- Electrical access and mounting location in the duct system
- Any duct modifications or sealing needed for proper exposure
- Pairing with other IAQ upgrades (filters, humidifier, or duct cleaning)
Schedule an on‑site air quality analysis to confirm the exact price and ensure correct sizing and placement.

Can an air purifier be repaired if the UV bulb stops working?
Yes, most UV air purifiers can be repaired when the UV bulb stops working. In many cases the fix is routine maintenance because UV lamps are consumable parts with a set service life. If the issue isn’t the lamp, a technician will evaluate power components and safety switches to decide if repair or replacement is smarter for the unit’s age and condition. Our team regularly services whole‑home UV systems in the local area near Fountaintown.
If you’re troubleshooting, these checks usually resolve it:
- Replace the correct UVC lamp type and reset any timer.
- Check the indicator light, fuse, or ballast/power supply.
- Clean the quartz sleeve or lens to restore output.
- Confirm the access‑door safety interlock is fully closed. We can provide an indoor air quality analysis and a free quote for UV repairs or upgrades. Always turn off HVAC power before handling UV equipment to prevent shock and eye injury.
