TANKLESS WATER HEATERS / FREE ESTIMATES
HOT WATER / SERVICE GUIDE
Tankless units heat water as it passes through. Sizing depends on the number of fixtures that may run together and the temperature rise needed. Existing gas, electrical, venting, water connections, and installation space also affect a conversion. When you call from North Hills, tell us what’s affected and when you first noticed it.
Matthew LuongMy tankless water heater was discharging water randomly. I had no idea what the issue was. But Sergio came by ASAP and helped diagnosed what could be the issue. It was determined that my water pressure regulator was broken and the water pressure was 140 psi. He replaced it with a new one the same day within an hour, and lowered the pressure to 50 psi, and no more water is discharging from my water heater anymore.Read review on Google

LOCAL NOTES / NORTH HILLS
Public facts about North Hills that affect tankless water heaters — each one links to its official source.
North Hills gets its water from LADWP. Its latest water quality report shows Valley sources averaged 103–140 mg/L as calcium carbonate in 2025, depending on the source — moderately hard to hard on the USGS scale. Hard water leaves mineral scale in tank water heaters and tankless heat exchangers, which is why flushing and descaling matter.

LADBS requires a plumbing permit to replace a gas water heater, unless a LADBS Certified Licensed Contractor makes a like-for-like replacement. Ask us whether your job needs one.

Choose the closest question. An onsite review is needed to confirm capacity and installation requirements.
Tell us which fixtures are open when temperature changes and whether the unit displays an error code. Simultaneous flow and temperature rise help frame the assessment.
Do not remove covers or adjust gas or electrical controls.
List the fixtures used together and when flow falls short. A unit can have continuous output within its rated flow capacity; multiple simultaneous draws may exceed it.
Share the pattern instead of estimating a flow rate yourself.
If a code or status light appears, note it without opening the unit. Maintenance requirements vary by model and manufacturer guidance.
We assess the fault and explain what can be checked safely.
A tank-to-tankless conversion can affect venting, gas supply, electrical needs, water connections, and space. Demand and the existing installation should be reviewed together.
Ask for a capacity and connection review before selecting equipment.
TEMPERATURE FLUCTUATESWHEN TO CALL
If water is actively leaking, call for guidance and keep clear of wet areas near electrical equipment. Do not open the unit or adjust gas or electrical controls. For a planned conversion or performance issue, an estimate request is a good starting point.

We review symptoms, the model, and visible connections. Any repair recommendation depends on the fault and service information available for the unit.
Tankless water heater overviewWe consider fixtures likely to run together and the temperature rise needed. Rated output and incoming water conditions affect the usable flow.
