Attached spas and standalone hot tubs share the same basic failure points: heaters that cycle on and off without reaching temperature, jets that've lost pressure because an internal fitting has cracked, control packs that display error codes without obvious explanation, and water that clouds up faster than it should because the circulation pump is running at reduced capacity. A spa that's used a few times a week but hasn't had a drain-and-refill or line flush in over a year is also carrying a mineral and biofilm load that chemistry alone won't address. These aren't emergencies in the traditional sense, but they do make the spa uncomfortable and, left alone, they accelerate component wear.
Spa service at K&D Quality covers the diagnostic and repair work—heater testing, circulation pump replacement, jet and manifold inspection, control pack troubleshooting, and cover lifter installation—as well as full drain-and-refills with a line flush to clear what's built up in the plumbing. Sundance, Hot Spring, Caldera, Jacuzzi, and most builder-grade attached spas are all on the service list. For spas that share an equipment pad with the pool, the plumbing layout is typically already familiar from weekly service, which shortens the diagnostic time. Most visits wrap up in under an hour and end with a written quote for any repair work identified.
For San Jose homeowners who use their spa regularly through the cooler months, reliable heat and clean water aren't optional. Spa and hot tub service in the South Bay means working on equipment that runs harder in fall and winter—heaters cycling more frequently, filters catching more debris, covers taking more weather. A well-serviced spa holds temperature efficiently, jets perform at full pressure, and the water stays clear between uses without requiring constant attention from the owner. Same-week scheduling means a spa that stops heating on a Tuesday doesn't have to wait until the weekend to get looked at.

Full-service weekly maintenance on a fixed route day. Includes brushing walls and tile line, vacuuming as needed, skimmer and pump basket emptying, filter pressure check, water testing for chlorine, pH, alkalinity, cyanuric acid, and salt, and chemical balancing. Equipment is visually inspected every visit and you get a text or email if anything's off. Same tech every week, never subcontracted. Most San Jose pools fall between $165 and $235 per month depending on size and tree cover.
Diagnosis and repair on every major brand: Pentair, Hayward, Polaris, Jandy, Sta-Rite, Zodiac, Raypak. Pumps, motors, filters, valves, plumbing, timers, pressure switches, unions, and o-rings. The parts that fail first ride on our truck, so most repairs close in a single visit. We tell you what's worth fixing and what's worth replacing, with the actual cost difference in writing before any work starts.
Full pool resurfacing for plaster pools showing stains, rough spots, hollow areas, or 15-plus years of wear, and fiberglass refinishing for gel-coat fading and osmotic blisters. Process includes drain, chip-out or prep, bond coat, new plaster or gel coat, fill and start-up chemistry over the first 28 days. Typical residential job runs 7 to 10 working days plus fill time. We coordinate the whole job, no separate contractors to chase.
Salt cell diagnosis, descaling, replacement, and full new-system installation. We install and service Pentair IntelliChlor, Hayward AquaRite, Jandy AquaPure, and CircuPool. Existing cell scaled out? We test cell output and plate condition before quoting a replacement, plenty of cells just need a proper acid bath. New install on a chlorine pool typically runs $1,800 to $2,400 installed for a residential South Bay pool, including the cell, control board, flow switch, and plumbing.
Gas heater and heat pump repair on Raypak, Pentair MasterTemp, Hayward Universal H-Series, and Jandy LXi and JXi. Common fixes: ignition control modules, pressure switches, gas valves, thermal regulators, heat exchangers. We also install replacement heaters and run new gas lines through licensed sub when needed. Cold pool the week before a party? We carry the most-failed parts and most repairs finish same day. Full replacement installs run 1 to 2 days.
Install, program, and repair pool automation: Pentair IntelliCenter and EasyTouch, Hayward OmniLogic and OmniHub, Jandy AquaLink and iAquaLink. We set up the app on your phone, label every relay, and walk you through schedules for pump speeds, heater, lights, and salt cell. Existing system glitching? Most issues trace to a failed actuator, a stuck relay, or a wifi gateway that needs reflashing, not a full board replacement. We diagnose before we sell.
