Why pay your HVAC company over a hundred to replace a lightbulb? nothing to it. Just make sure the unit is off before opening the ventilation unit. The UV light from your current light bulb can damage your eyes. This is the third year I have been using the model/brand of lamp. Everyone survived and did not burn. My HVAC company charges $175 for a replacement.
