 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Keep Your System Clean Year-Round

UV bulbs lose strength over time and need periodic replacement to keep working. The Lighthouse Annual Maintenance Plan checks and maintains your UV system along with your HVAC, so your air stays clean and your coil stays protected — season after season.

Still Have Questions? Let Us Help

Do UV light systems for HVAC actually work?

Yes. UV-C light is proven to neutralize mold, bacteria, and other microorganisms. Installed inside your HVAC system near the coil — where dampness lets mold and biofilm grow — it stops them at the source, keeping your coil clean and your air free of the contaminants your system would otherwise circulate.

Where is the UV light installed in my system?

The UV lamp is installed inside your air handler, typically near the evaporator coil. That's where cool, damp conditions encourage mold and bacteria to grow. Placing the light there keeps the coil clean and treats the air as it passes through, protecting both your air quality and system efficiency.

Can a UV light help with musty smells and mold?

Yes — it's one of the most effective solutions for that. Musty smells when your AC runs are often caused by mold on the coil. A UV light system continuously kills that growth, eliminating the odor at its source rather than just masking it.

Does a UV light system improve efficiency?

It can. A coil coated in mold and biofilm can't transfer heat as well, forcing your system to work harder. By keeping the coil clean, a UV light system helps your HVAC run more efficiently — supporting both lower energy use and a longer equipment life.
