Water heaters don’t last forever. The average lifespan of gas and electric water heaters ranges from 8-12 years. While repairs can be made dependent on the issue, sometimes the only option is to replace the unit.

Associates Plumbing has been installing all types of residential and commercial water heaters for over 30 years. We have consistently provided our customers with peace-of-mind by replacing units to ensure hot water is promptly restored to the property. Our company prides itself on our knowledge of the regulations related to water heater installations. We secure permits and have all units inspected to verify full compliance with plumbing code standards.

API’s focus has always been on delivering value to our customers. With that goal in mind, we have established exclusive warranties for commercial State brand water heaters. Any commercial State water heater we install at your property will include a free extended 5-year Replacement Parts and 5-year Manufacturer’s Tank warranty.

Call us now at (443) 917-2500 to schedule the installation of your new water heater or to perform repairs on your existing unit. We can also conduct surveys to inspect your current heaters and advise on recommended repairs and / or replacements.
