Fountain Valley Job: Cold Floors in a New Remodel
We got a call from a homeowner near Fountain Valley High. They had just remodeled their kitchen and bathroom, but their radiant floors weren’t warming up. Everything was brand new—including tile—and they were worried the whole system had been wrecked.
We checked the loops and found the zone control for that section had failed. It wasn’t calling for heat even though the rest of the house worked fine. With a quick swap and pressure test, we got heat flowing again. No demo, no drama.
The owner said they called us because we’re local—and because we actually work on hydronic systems.
What Can Go Wrong With Hydronic Heat in Fountain Valley
Hydronic heating setups work great when they’re maintained, but we’ve seen plenty go sideways around Fountain Valley. One common issue is air trapped in the loops. That causes heat to spread unevenly, leaving some rooms cold while others get too warm. Circulator pumps also tend to fail after years of use, especially if the system’s been running dirty or has hard water buildup.
Leaky valves and manifolds can throw off water flow, and without good pressure balance, zones stop responding the way they should. We’ve also seen controls or thermostats completely fail—especially in older homes where upgrades never happened. Expansion tanks that’ve gone waterlogged can cause banging pipes and weird pressure shifts.
Sometimes it’s not even the heating parts—just poor plumbing design or old water chemistry messing up the whole system.

DIY Hydronic Heating Repairs We’ve Fixed
One homeowner added an extra pump from a hardware store thinking it’d make the system faster—it didn’t. We’ve also seen thermostats wired wrong, causing zones to overheat or not fire at all. One guy even bypassed his mixing valve and burned the tubing right under the laminate floor.
This stuff’s not like regular plumbing. There’s pressure, balance, and temperature control involved. If you guess wrong, you risk popping a joint or ruining expensive finishes.
