Hot Water When You Actually Need It

Water heater installation, repair, and replacement services in Brunswick

If your morning shower in Brunswick is running cold halfway through or your water heater is making banging noises from the basement, those are signs the system is struggling to keep up. Water heaters fail gradually, and what starts as lukewarm water during high use can quickly turn into complete loss of hot water. Whether your unit is old and inefficient or a newer model with a fixable issue, addressing the problem early can prevent an emergency replacement on the coldest day of the year.

A and O Plumbing and Heating Services installs and services water heaters in homes and light commercial properties throughout Brunswick. The team works with electric, gas, propane, and oil-fired units, as well as tankless systems. They handle installations in older Maine homes where access and venting can be tricky, and they also service systems in newer construction. If your water heater is not performing the way it should, the crew can assess whether repair or replacement makes the most sense based on the age and condition of the unit.

If you are dealing with inconsistent hot water or suspect your system is failing, contact the team to schedule a service call.

What happens during installation or repair

When you schedule water heater service in Brunswick, the technician starts by inspecting the existing unit to identify the cause of the problem. If the issue is a faulty heating element, thermostat, or pressure relief valve, they can often complete the repair on the spot. If the tank is corroded or leaking, replacement becomes necessary, and the crew will remove the old unit, install the new water heater, and connect it to your existing fuel line and water supply.

Once the new system is running, you should notice consistent hot water temperature during showers, dishwashing, and laundry. Recovery time between uses will improve, especially if you switch from an undersized tank to a properly sized unit or upgrade to a tankless model. Many homeowners also see a reduction in energy use if they replace an older, less efficient tank with a newer model.

The team works with standard tank-style heaters in 40, 50, and 80-gallon sizes, as well as on-demand tankless units that heat water only when needed. They also handle hybrid heat pump water heaters for homeowners focused on long-term efficiency. Installation time varies depending on the type of system and whether any modifications to venting or electrical service are required.

Questions that come up before service

Homeowners often want to know how long a water heater should last, what size makes sense for their household, and whether repair is worth it compared to replacement. These answers cover the practical details that help you make an informed decision.

How do I know if my water heater needs to be replaced?
If your water heater is leaking from the tank, producing rusty water, or over 12 years old with declining performance, replacement is usually the better option. Repairs make sense for newer units with isolated component failures like a bad thermostat or heating element.
What size water heater do I need?
Most households do well with a 40 to 50-gallon tank, but if you have a larger family or use multiple bathrooms simultaneously, you may need an 80-gallon unit or a tankless system. The technician can recommend sizing based on your water usage patterns.
How long does installation take?
A standard tank replacement in Brunswick typically takes two to four hours depending on access and whether any modifications to venting or piping are needed. Tankless installations may take longer due to additional electrical or gas line work.
Why is my water heater making noise?
Banging or rumbling sounds usually come from sediment buildup at the bottom of the tank. Flushing the tank can reduce the noise, but if the problem persists or the unit is old, it may be time to replace it before the tank fails.
What types of water heaters do you work with?
The team installs and services electric, gas, propane, and oil-fired water heaters, as well as tankless and hybrid heat pump models. They can help you choose the type that fits your fuel source, space, and efficiency goals.
