Best HVAC Accessories — UV Lights, Surge Protectors | LC Heating & Air

Protection Accessories

HVAC Surge Protector: Modern ACs and furnaces contain expensive control boards and inverter drives. A power surge or lightning strike can fry a $1,500 component instantly. A dedicated HVAC surge protector sacrifices itself to save your system.
Float Switch / Drain Pan Alarm: ACs produce gallons of condensation daily. If the drain clogs, water overflows. A $150 float switch shuts off the system before water ruins your ceiling or floors. (Required by code on new installs).
Compressor Hard Start Kit: Gives older or struggling compressors an extra jolt of electricity to start up, extending their life and preventing lights from dimming when the AC kicks on.

Indoor Air Quality (IAQ) Accessories

UV Germicidal Lights: Installed directly over the indoor AC coil. The UV-C light continuously sterilizes the dark, damp coil, preventing mold and bacteria growth that causes "dirty sock syndrome."
Air Scrubbers (Active Catalytic): Installed in the ductwork. These use UV light and rare metals to create oxidizers that actively hunt down and neutralize viruses, VOCs, and odors throughout the home.
4-Inch Media Filter Cabinet: Upgrading from a standard 1-inch filter to a 4-inch deep pleated filter provides superior MERV 11-13 filtration and only needs changing every 6–12 months.

Frequently Asked Questions

Are UV lights in HVAC systems worth it?

Yes, especially in humid areas or homes prone to allergies. A basic UV light keeps the indoor coil free of mold and biological growth, improving efficiency and preventing musty odors.

What does a hard start kit do?

A hard start kit is a capacitor and relay that provides a massive, temporary boost of power to the compressor during startup. It reduces mechanical stress, helps older units start reliably, and stops your house lights from dimming.
