Hot water repair: fast fixes for no hot water
When the tap runs cold, there are only a few likely culprits—and we track them down quickly. Our techs arrive with parts, meters, and combustion tools to find the why behind the what, not just band-aid the symptom. From hot water repair services for temperature dips to safety shutoffs that cut heat, we restore comfort without upsell pressure.
If your water heater not heating, it may be a failed igniter, tripped high-limit, bad thermostat, or sediment choking heat transfer. We test, confirm, and fix—then show you what happened so it’s less likely to happen again.
What to check before you call (and when to call us 24/7)
Confirm power or gas is on, make sure the breaker hasn’t tripped, and verify the gas valve is open. If you smell gas, hear popping/booming, or see water near electrical components, call for emergency water heater repair immediately. Safety first, always.
When “water heater not heating” points to a deeper issue
Intermittent hot water often signals a failing thermostat or sensor; rapid temperature swings can indicate scale buildup or a misreading probe. We calibrate controls, flush safely when appropriate, and set gas pressure to manufacturer spec. Goal: stable, efficient hot water—not a quick fix that fails next week.
Leaking water heater: find and fix leaks
A leaking water heater wastes energy and can damage floors and walls. Whether the unit is leaking from bottom or top, our team isolates the source before recommending a fix.
We commonly repair pressure relief valve leaking, drain-valve seepage, and flex-line drips. If the tank itself is compromised, we’ll document the finding and walk you through options—no scare tactics. Expect photos, clear explanations, and a plan that matches your budget and timeline.
Water heater leaking from bottom or top
Top leaks point to fittings, cold-in/hot-out lines, or the T&P connection. Bottom leaks can be condensation, a loose drain valve, or—worst case—corrosion. We rule out simple causes first, repair what’s repairable, and only suggest replacement if the tank has actually failed.
Pressure relief valve leaking vs. other leak sources
A T&P valve can open from excessive temperature or pressure. We test expansion, check pressure regulators, and verify thermostat accuracy. If the valve is fine, we track down the real source so you don’t keep swapping parts unnecessarily.
Tank & tankless water heater repair
We fix both traditional tanks and modern on-demand systems—all major brands, gas and electric. If you need help right now, that’s exactly what we do.
Tank water heater repair
For gas water heater repair, we inspect ignition sequence, gas pressure, venting, and thermostat issues. For electric water heater repair, we meter elements and thermostats, check wiring integrity, and look for ground faults. Many “end-of-life” calls turn out to be simple control or sensor faults. We prove the problem before we touch a part.
Tankless water heater repair
Tankless systems speak in tankless water heater error codes. We read the codes, verify with real-world measurements, and repair the cause—scale at the heat exchanger, igniter problems, gas supply variability, or tankless water heater not heating due to flow-sensor errors. Once fixed, we share simple usage tips to keep on-demand performance crisp.
Professional diagnosis: common problems we fix
Great repairs start with great diagnostics. Our trucks carry combustion analyzers, manometers, electrical meters, and manufacturer references so we can solve your issue in one visit whenever possible. Think of us as your water heater troubleshooting service—thorough, transparent, and tuned to Boulder’s real-world conditions (hard water, cold snaps, altitude).
Ignition & pilot issues
From a pilot that keeps going out to full water heater ignition failure, we test thermocouples, flame sensors, ignition modules, and gas delivery. If drafts or ventilation contribute, we correct the root cause so the flame stays lit and stable.
Thermostat, sensors & safety
If you’re seeing temperature fluctuation, random shutoffs, or a high temperature shutoff reset situation, we verify thermostats and safety chains end-to-end. Our professional diagnosis avoids “parts darts” and gets you back to predictable hot water fast.
