FAQs
How do UV lights improve indoor air quality in my Winchester home?
Germicidal ultraviolet (UV-C) lamps are installed inside your HVAC system, usually near the evaporator coil or in the supply plenum. The UV-C wavelength disrupts the DNA of mold, bacteria, and many viruses, preventing them from reproducing. As the air in your ductwork circulates past the lamps, these microorganisms are neutralized, resulting in cleaner supply air, fewer odors, and reduced microbial growth on coils and drain pans. This keeps your system cleaner and helps safeguard the air your family breathes.
Are HVAC UV lights safe for my family and pets?
When professionally installed inside the air handler or ductwork, the light is fully contained and never shines into occupied spaces, so there is no direct exposure risk. UV-C radiation is harmful only with prolonged direct eye or skin contact, which is why the units have metal housings and safety interlocks. During maintenance, our technicians power down the lamps and wear protective gear. Used properly, UV lights are a safe, chemical-free way to disinfect your air.
Will installing UV lights affect my energy efficiency and utility bills?
UV lamps themselves use very little electricity—most residential models draw 15–25 watts, comparable to an LED bulb. Indirectly, they can lower energy use because a cleaner evaporator coil transfers heat more efficiently, allowing your air conditioner to run less. Studies show coil fouling can raise cooling costs by up to 30 %; keeping the coil free of biofilm with UV light helps you avoid that penalty. Overall, homeowners typically see negligible additional power cost and may even experience slight savings over time.
How often do UV lamps need to be replaced and what maintenance is required?
The bulbs lose germicidal strength gradually, even if they still light up. For maximum effectiveness, we recommend replacing them every 12 months, or 9,000 operating hours. Maintenance is simple: during your annual HVAC tune-up our technician will swap the lamp, wipe the quartz sleeve, check the ballast, and confirm the safety interlock. No other upkeep is necessary, making UV lights one of the lowest-maintenance IAQ upgrades available.
Can UV germicidal lighting help reduce allergens and respiratory issues?
Yes. By neutralizing mold spores, bacteria, and some viruses before they circulate through your supply vents, UV lights lower the overall microbial load in your home. This can lessen allergy triggers, reduce musty odors, and decrease the chance of respiratory irritation. While UV alone won’t remove dust or pollen—an upgraded filter handles particles—the combination of proper filtration and UV disinfection provides comprehensive protection for allergy and asthma sufferers.
What is the cost of installing UV lights in my existing HVAC system, and are there rebates in Winchester?
A typical whole-home UV installation ranges from $350 to $700, including the lamp, ballast, mounting hardware, and labor. Costs vary with lamp strength, single vs. dual-lamp setups, and whether extra wiring is needed. Winchester utility companies occasionally offer indoor air quality incentives, and Dominion Energy’s Home Energy Check-Up program sometimes includes rebates for coil irradiation systems.
