Failed capacitors and contactors on hard-running systems
Why it happens here
Cooling runs from March into November here, and systems near the hospitals often run around the clock. That runtime wears out start capacitors and contactors faster than in a typical home, and the failure usually shows up on the hottest day of the year.
Our approach
We test capacitors and contactors with a clamp meter on every maintenance visit and replace weak ones before they fail. Our vans carry the common ratings, so a failed capacitor in Medical City is usually a same-day fix.
