Heaters to winterization — the complete board of jobs the shop takes, each with its own procedure.
Every one runs the same rails: measure first, one written quote, then the wrench.
No heat, lukewarm water, overheat trips — element, sensors and relay tested in that order.
Details →Humming, grinding, tripping or just silent — wet end and motor diagnosed as the separate parts they are.
Details →Falling water level, wet skirt corners, soaked foam — found by procedure, fixed at the joint.
Details →Weak seats, dead air, stuck diverters, cracked jet bodies — flow restored end to end.
Details →Spa packs and topside panels — relays, sensors, boards and displays, repaired at component level where it pays.
Details →Breaker trips, dead power, wet connections — the leaking component found and isolated inside the cabinet.
Details →Full drain, line purge, mineral flush, filter service and a chemistry reset matched to local water.
Details →Proper shutdowns before the freeze and honest spring start-ups after it.
Details →Tri-City Spa Mechanics is deliberately narrow: self-contained hot tubs and swim spas, inside the cabinet, nothing else. That narrowness is where the speed comes from — the vans are stocked for exactly these eight jobs, and the diagnosis routine for each is a practiced sequence rather than an exploration.
The boundary matters too. House wiring, disconnects, supply plumbing and installations are other trades' work; when your fault lives there, you hear it from us directly along with who to call instead.
Describe the symptom. Matching it to the right procedure is the free part.
