Heating and plumbing has been in the Ertel family since 1926, and it's grown every year since.
William Ertel, who owns of R&J Ertel Inc. with his brother Daniel, explained that the current family business started over 30 years ago with his father John.
"My father incorporated the business in 1970," he said.
But the family's work in plumbing and heating started in the mid 1920s as his grandfather started Ertel Plumbing and Heating.
Now days R&J Ertel Inc. offers a variety of services, including construction services, energy services, engineering and design, sheetmetal manufacturing and maintenance.
William said he and his brother started in the business young.
"We were involved in the family business from our youth," he said.
After graduating from Bucknell University with a degree in mechanical engineering - Daniel with a civil engineering - the two decided to "make a go at" the business.
"So when we graduated in May of 1984, we decided to come back here and grow the business," William said.
Although the company was always focused around heating, plumbing and air conditioning, in 1985 the brothers introduced design and engineering to it.
Williams explained that with this service, R&J Ertel will go in and custom design a system for a specific building and then build it. He said it allows the customer to have a "seamless" project as they aren't dealing with multiple contractors and workers.
"It means the customer only really has to interact with us," he said.
He said they also don't leave the job unfinished, while the customer waits for another contractor to complete the job.
"We don't leave the customer with a hole," William said.
But the day they finish a job, isn't the last the customer will see the company as they service and maintain each job they do.
"When you see us that last day your system is installed, that shouldn't be the last day you see us," William said.
He also said that when a customer calls the company that they will speak to a person, not an automated recording. Once the customer speaks with someone, they will be directed to a person with the expertise their job requires.
"I think the range and expertise of service that we offer in mechanical construction ... there's not a whole lot that we're not going to be able to do," William said.
In the coming years, William hopes the business continues to grow as it has every year. He said there's always training and schooling its employees are getting to be the most up-to-date.
"We grow every year except the recession year we just went through. In 10 years I hope we're still growing," he said.
