A Routine Maintenance Call That Found a Bigger Problem

HVAC maintenance visit that led to a full system replacement, Northwest Fresno
NORTHWEST FRESNO · 3-ZONE SYSTEM

Julie D. has been a returning customer — we’d serviced her unit before. This time, a closer look changed the outcome.

What we found

Corrosion nobody had caught before

We went out for a standard maintenance visit on Julie’s 3-zone system. On inspection, the condenser showed clear signs of corrosion from ammonia exposure — the household dog had been using the outdoor unit as a regular spot. The team ran a full check on the gauges and system operation, and the temperature split wasn’t where it should have been. After walking Julie through what we found, she made the call to replace the system rather than patch around a unit that was already compromised.

The outcome

Full replacement, same-visit decision

Because we already had the diagnostic data in hand, Julie could make an informed decision on the spot instead of waiting on a second visit. The system was replaced, and as a returning customer, she’s someone we’ll keep checking in on going forward.
