01

What changed with the water heater?

Tell us when the hot-water problem began and whether the equipment is running, leaking, making noise, showing a code, or producing water that is too hot, too cool, or inconsistent.

02

Is there no hot water, too little hot water, a leak, or unstable temperature?

Those symptoms can point to different equipment, control, fuel, electrical, venting, or water-side conditions. If water is near electrical equipment, keep clear of the area and do not touch the equipment.

03

What should be checked before service or replacement is chosen?

The fault, equipment condition, hot-water demand, installation location, connections, controls, venting where applicable, and access all affect the next step. The symptom alone does not settle the decision.

04

What should be checked before selecting a new water heater?

The household or property demand, available fuel and electrical service, venting, equipment location, drainage and protection, connection points, and removal path all shape the installation.

05

Is the equipment a water heater, boiler, or combination unit?

A water heater supplies domestic hot water. A boiler heats the building. Combination equipment can do both. Share the model or a photo when it is available and describe whether the problem affects taps, space heat, or both.

06

What do fuel, venting, electrical supply, location, and demand change?

They change which equipment can fit, what connections are needed, how the system operates, and what the complete installation includes. United checks the actual property before treating the scope as final.

07

What should you do if a carbon monoxide alarm sounds or you smell gas?

If a carbon monoxide alarm sounds, get everyone to fresh air and call emergency services. If you smell natural gas, leave immediately and call 911 and the gas utility from a safe location.

08

What should you send with a water-heater request?

Share the property type, the hot-water symptom, when it began, any leak, odor, alarm, or control code, and the equipment location. A model number or photo can help when it is safely accessible.
