About this product

UV Replacement Lamp — manufacturer part number LSK07403H-16/5.

What this part does

UV lamps keep the evaporator coil free of mould and biofilm. The bulb keeps glowing long after its useful output has gone, so lamps are replaced on a calendar, not when they die.

Replace this part if

  • Lamp is past its rated 1-year or 2-year service life
  • Musty smell returning from the vents
  • Visible growth on the evaporator coil
  • Lamp is dark or flickering

Install difficulty

Easy — about 15 minutes. Tools: Screwdriver, clean gloves. Power off at the breaker: yes. Gas shutoff required: no.

Safety warning: Never look directly at an energised UV lamp -- it will damage your eyes. Cut power at the breaker before opening the housing, and handle the new bulb with gloves; skin oil creates hot spots that shorten its life.

Typical service life is 1-2 years. Most HVAC companies charge $200-350 to replace this part, including the service call.

Saved $2,400 vs local contractor

Got quoted $9,200 from a local HVAC contractor for a furnace replacement. Found Furnace Direct and got the exact same Goodman unit for under $5k delivered. My installer couldn't believe the price and installed it in one day. Runs perfectly.

Fast shipping, exactly as described

Ordered on a Tuesday, pallet arrived Friday. Unit was packed well, no damage, all factory sealed. Andrew answered my sizing question over the phone and got me the right model. Couldn't be happier with the purchase.

Installer said same one he'd buy at supply house

My HVAC guy said he pays basically the same price at his wholesale supply house. The markup contractors add is insane. Furnace Direct cut the middleman out entirely. Will recommend to everyone I know.

Heating my 2,200 sq ft home perfectly

Installed my 96% AFUE furnace a couple months ago. Heats my 2,200 sq ft home perfectly, and my gas bill dropped noticeably compared to the old unit. Great product, great price, great experience from start to finish.

Saved enough to pay for the install

Math was simple: 3 contractor quotes all over $8k. Furnace Direct plus local installer was under $5,500 total. Saved enough to basically pay for the install myself. Quality is identical to what contractors charge a fortune for.

No-pressure, honest pricing

Called a few HVAC companies first — every single one wanted to schedule an "in-home consultation" before giving me a price. Furnace Direct just showed me the price. Bought online, shipped next day, done. This is how it should work.
