About Dale & Lee's

Who We Are

Dale & Lee’s Service finds its roots in the early 1960s, when Dale DeBoer began offering repair services for washers and dryers under the name Dale’s Commercial Service. Dale’s professionalism, knowledge, and amicable nature quickly won him the trust of his customers, who began requesting heating and air conditioning repairs. Recognizing this demand, Dale joined forces with his older brother Lee DeBoer to establish Dale & Lee’s Service in 1966.
The brothers formed a harmonious partnership: Dale overseeing sales and installations, Lee managing the service side, and Dale’s wife Marilee handling the office and bookkeeping. Their joint effort, driven by passion, quality, and customer-centric principles, flourished over 40 years, setting a strong foundation for the business.

The History

In 2009, the torch was passed to the second generation of Dale & Lee’s Service’s owners. Dale & Marilee’s youngest son, Brent, took over the company. Brent now manages sales and installations, while his older brother, Brian, oversees the service side of the business. 
Brent and Brian, who have grown up working in the company and boast over 30 years of experience each, carry forward the values and principles instilled by their parents. Currently, Brent’s sons are being groomed to carry the legacy of Dale & Lee’s Service into the third generation, ensuring the continuous provision of quality service and installation for commercial and residential heating, air conditioning, and plumbing needs.
The entire DeBoer family is committed to earning the right to fulfill your Heating, Air Conditioning, and Plumbing sales and service needs. With Dale & Lee’s Service, you’re not just getting a service provider; you’re becoming part of a tradition of excellence.
