About Us

Larry (Owner)


I started Wilson Service Company on April 1st, 2013 and I've been lucky enough to learn a thing or two over the years. I have worked hard to make sure that my customers know, that I have the most up-to-date information and knowledge of their home comfort systems and I always have their best interests at heart. Keeping them comfortable is my goal! 

My story began as a child... 

For as long as I can remember, I have always had a craving for taking mechanical things apart just to figure out what made them tick and just to see if I could put them back together. My Granny had often told a story of me as a child taking her broken toaster apart, fixing it and giving it back to her. While I do not remember doing this, it never came as a surprise as it sounded just like me. Growing up, it was toys, bicycles, then cars, trucks and later on computers... I just had to take things apart just to see how they worked and if I could improve their performance. As an adult, I still do these things just with much bigger appliances and it ranges in everything from motorcycles to iPhones. (no, not mine... family & friends bring me their iPhones for repairs, usually shattered screens. lol)

My background in the Heating and Cooling Industry began in 1991 as I was employed by a local Manufacturing Company that produced commercial kitchen heating and refrigeration equipment.     

My education in HVAC began in 1995 when the fore mentioned company put me through a two week course were I acquired my EPA Refrigerant Certification. In July 1997 I started Classes at Johnson County Community College (JCCC) in HVAC technology. To present day, I have taken numerous (too many to mention) HVAC related Credit Courses, Training Courses, Continuing Eduction Courses, seasonal refresher classes, product training classes, Seminars and Webinars (most of which at JCCC) that eventually lead up to the Master Mechanical Certification (License) that I hold. This is an industry that demands continuing education and as such there will never be an end date for my education.  

My employment history as mentioned before started in 1991 building commercial kitchen equipment. From 1997 to 1999 I worked in the Franklin, Douglas and Miami County areas as a HVAC Service and Installation mechanic. From 1999 to 2013 I worked in the Johnson County and Kansas City Metro areas at first as a Service and Installation Mechanic, then Dispatcher, Customer Service Representitive, Sales Representative, and Service and Installation Manager. (Most of these were all at the same time). 

With each company I was employed over the past 27+ years, I have always been that one guy that wore many hats, that "Go to Guy"  that can do and did just about every job within that company, so consequently I have always been that one person that everyone leaned on and counted on to get things done and make things happen. 

To be continued....

Sandy (Technician)


When Larry started Wilson Service Company he only envisioned being a one-man show. However, as business grew so did the need for a second person. As a family ran business many people don’t know that Sandy is actually Larry’s son-in-law. What started as Sandy helping out every now and again turned into a couple days a week, and now he works full-time for WSC.

Sandy grew up in Newton, Kansas in a large family of 5 children. After graduating high school he moved to Franklin County. It took a couple moves back and forth before he decided to permanently stay in Ottawa. Sandy has 3 children (Larry’s grandchildren) – 2 boys, and just welcomed a baby girl in June of 2017.

Sandy started off working in the medical field as a firefighter and EMT. Then he transferred into working in long-term care. In fact, he actually still works there on the weekends passing medications because he enjoys the residents he takes care of. That being said, like many people, he grew tired of doing the same tasks day after day and was looking for a change. HVAC has given him that new passion to accept a new challenge daily.

Sandy received his fire fighting training through the University of Kansas, and his EMT training at Hutchison Community College. Then he moved on to do his CMA/CNA training through Hutchison Community College and Neosho County Community College. Although Sandy is still interested in volunteer fire fighting, with the needs of his young family he doesn’t feel like he has the time to provide the commitment needed. Sandy also has a passion for meteorology and storm chasing and is part of the storm spotter network. Sandy also enjoys taking many pictures and videos.

Sandy has been with WSC since August of 2016 and has become a huge asset to our company. With continued training and as a certified EPA technician Sandy takes on many of the day-to-day tasks such as service, repairs, and installations. Sandy is known for taking his time, double-checking, and making sure the HVAC system is operating properly and safely before leaving. Sandy takes great pride in his workmanship.

Charity (Administrative Assistant)


Charity takes care of Wilson Service Company behind the scenes with customer service, scheduling, social media accounts, marketing, as well as our website, blogs and a few other odds and ends that need done to keep the business running smoothly and growing Wilson Service Company.

Charity grew up in the Ottawa area and graduated from Ottawa High School. She went on to Johnson County Community College studying healthcare. She spent several years working in healthcare and is presently works part-time nights/weekends in healthcare as a phlebotomist in Lawrence.

Switching from full-time nights to working from home with Wilson Service Company has allowed Charity the opportunity to be home with her and Sandy’s children. However, Charity knew she wasn’t ready to give up healthcare all together and enjoys the nights she spends in the laboratory. 


As Wilson Service Company is a family business, Charity is also Larry’s daughter (and future caregiver). When she’s not working these two jobs, she is the mother to 3 wonderful children: Colton 10, Connor 4 and Savannah is 1.  

Charity enjoys spending her free time with her kids, baking goodies, and craft projects. She has been the co-president of the PTA at her kids school the past couple years as well as volunteer room mother and huge supporter for her kids sports and other activities.
