Standard Coverage

BioShieldUV 1-Year Limited Warranty

Every BioShieldUV system includes a 1-year limited warranty covering the unit components — ballast, housing, electrical connections, and mounting hardware — against manufacturing defects and component failures under normal use. bioshielduv.com

✓What's Covered

Manufacturing defects in materials and workmanship, component failures under normal operating conditions, ballast malfunctions, housing and mounting hardware defects, and electrical connection failures. bioshielduv.com

✗What's NOT Covered

TruBlue™ UV bulbs (separate policy applies), damage from improper installation, power surges, normal wear and tear, misuse, environmental damage, or units modified by unauthorized persons. bioshielduv.com

Critical: TruBlue™ UV Bulb Policy

Bulbs are NOT covered under the 1-year unit warranty. The standard bulb coverage is a 14-day DOA (Dead on Arrival) policy only. If a bulb is non-functional upon delivery, you have 14 days to request a replacement. After 14 days, there is no bulb coverage under the standard warranty — even if the bulb fails in the first few months. bioshielduv.com

Guardian Club

Standard Warranty vs. Guardian Club

The Guardian Club is BioShieldUV's comprehensive protection and maintenance program — lifetime unit warranty, 6-month bulb warranty, and automatic bulb delivery every 10 months. bioshielduv.com

Coverage Area Standard Warranty Guardian Club
Unit Warranty 1 year limited Lifetime
Bulb Warranty 14-day DOA only 6 months (180 days)
Bulb Pricing Full retail Discounted member pricing
Auto Bulb Delivery No Every 10 months

How We Compare: Warranty Across Brands

Not all HVAC UV-C systems are covered equally. Here's how warranty and protection compare across popular residential brands — based on publicly available manufacturer information as of early 2026.

*Fresh-Aire UV Note: Fresh-Aire UV's lifetime warranty on parts explicitly excludes lamps and requires installation by a licensed HVAC or electrical contractor — installation by anyone other than a licensed professional voids the warranty. Their Mini UV product carries a 5-year warranty instead of lifetime. Pricing and warranty details are based on publicly available manufacturer and retailer information and may change. BioShieldUV is not affiliated with any competitor brands listed.

Real Scenarios

What Happens When Something Goes Wrong?

Six real-world situations showing exactly how coverage works — and what it costs you.

1
Bulb fails at 2 months — No Guardian Club
Not Covered

Bulb stops working after 2 months of use

None — bulbs are not covered under 1-year unit warranty, and 14-day DOA has expired

Full retail bulb price

Without Guardian Club, you have zero bulb protection after the 14-day DOA window — even during Year 1.

2
Bulb fails at 2 months — Guardian Club Member
Fully Covered

Same bulb failure at 2 months

Full replacement under 6-month bulb warranty

$0 — completely covered

Guardian Club's 6-month bulb warranty provides 26x longer protection than the 14-day DOA policy.

3
Bulb fails at Day 20 — No Guardian Club
Not Covered

Bulb fails just 6 days after DOA window closes

None — 14-day DOA expired

Full retail

The 14-day DOA window is strict. Even a failure at Day 15 is not covered without Guardian Club.

4
Bulb fails at Day 20 — Guardian Club Member
Fully Covered

Same Day 20 bulb failure

Full replacement — well within 180-day window

$0 — completely covered

5
Unit fails at 13 months — No Guardian Club
Not Covered

Unit component fails 1 month after warranty expires

None — 1-year warranty has expired

Full replacement unit cost

You can still rejoin Guardian Club by paying 50% of current model price — this immediately activates lifetime unit warranty and covers even existing issues.

6
Unit fails at 13 months — Guardian Club Member
Fully Covered

Same 13-month unit failure

Full replacement under lifetime warranty

$0 — lifetime coverage

This is the single biggest advantage of Guardian Club — unit protection that never expires.
