Core (Universal)Question 40 of 240
A homeowner asks a technician to just 'top off' a leaking R-22 system every summer instead of fixing the leak. Why is intentionally not repairing a significant leak a problem?
a.It has no downside as long as the system cools
b.It is only a concern for commercial systems
c.It voids the thermostat warranty
d.It keeps emitting ozone-depleting refrigerant
Explanation
Repeatedly recharging a leaking system wastes scarce, phased-out R-22 and allows an ozone-depleting refrigerant to escape into the atmosphere, exactly the outcome Section 608 is designed to reduce. It is not merely a warranty or commercial-only issue, and there is a real environmental and cost downside. Good practice is to find and repair leaks rather than continually add refrigerant.
