Water Heater Installation and Repair (Standard and Tankless) FAQ

Q1: How do I know if I need to repair or replace my water heater?

A: If your unit is over 10 years old, frequently breaks down, or can’t provide consistent hot water, replacement may be more cost-effective. Newer units are also more energy-efficient, thus saving you money in the long run.

Q2: What’s the difference between a standard and a tankless water heater?

A: A standard water heater stores hot water in a tank, while a tankless system heats water on demand. Tankless systems are more energy-efficient and provide unlimited hot water, but may have a higher upfront cost. Tankless water heaters are also smaller, and sometimes necessary if space is limited.

Q3: How long does installation take?

A: Most installations are completed in a single day. We’ll remove the old unit, install the new one, test it thoroughly, and clean up the work area.

Q4: Do you service all brands of water heaters?

A: Yes, we work with most major brands and can source reliable replacements if needed.

Q5: How often should I maintain my water heater?

A: Standard units should be flushed annually to remove sediment buildup. Tankless systems also benefit from regular maintenance to ensure long-term performance.
