FAQs

Why is my First Company air handler not turning on?

Check the thermostat, breaker, and float switch. Power issues or a tripped float switch are common causes.

Why is there water leaking from my First Company fan coil unit?

Usually caused by a clogged condensate drain or damaged pan. Clear the drain and inspect the drain pan for cracks.

Why is the blower motor on my First Company unit noisy?

Worn bearings, loose mounting, or debris in the fan wheel may cause noise. Replace or tighten components as needed.

My First Company unit isn’t cooling properly—why?

Could be due to low refrigerant, dirty coils, or a faulty TXV. Check pressures and clean the evaporator coil.
