After more than a decade of seeing the poor standard practices of some other heating and cooling companies, Mark Dickerson decided to do things differently. In 2012, he founded Mark’s Heating and Air, working evenings and weekends. By 2016, he took his company full time and is continuing to grow each year. He attributes this growth to the dedication of his employees of making sure each job is completed accurately and that the customer is fully satisfied. Mark has multiple crews working under his banner and they follow his lead of integrity.

“Prior to starting my own business, I saw so many customers treated unfairly and I just did not want to be a part of that,” Mark explained. “For example, many HVAC companies try to sell customers things that they just do not need, like a new and costly unit, when a simple and inexpensive fix is all that was needed.” Many companies are reputable but not all of them; people trust that they are being told the truth when sometimes they are being lied to. This bothers Mark so much that he offers a free second opinion, much like a medical second opinion, to anyone who requests it. If someone has received a service quote of what needs to be repaired or replaced and the cost of such, Mark is glad to have his team check the same issue. They will then let the customer know if the original diagnosis and estimate is along industry standards or if they may be in danger of working with a disreputable company. Mark does not charge for this service and hopes he can help people not find themselves in a precarious situation.

Mark’s Heating and Air is located in Sparta, but serves all the surrounding counties and occasionally beyond. They service all types of units and they do warranty work as well, even if the original unit was not purchased from them. They do residential and light commercial work, as well as new construction work. This includes new installs, change outs, and general repair work.

One big difference between Mark’s Heating and Air from their competitors is that they never charge an after-hours fee. When asked why he does not charge for late hours or weekend visits, Mark explains that when he first started and was only doing HVAC work part-time, in the evenings and on the weekends, he did not feel it was right to charge his customers extra since those were the only hours when he was available at the beginning. “Customers are in a difficult enough position if their air conditioning goes out on a Saturday morning in the middle of the summer without them having to worry about paying extra fees simply because it is the weekend,” Mark says. “The same goes if their heat stops in the winter. The lack of adequate heating or cooling can be a debilitating health risk and it can be critical to be able to reach a professional repair company during these times.” When Mark took his business full-time, he decided to keep the policy of no extra costs for after-hours calls.

Mark is also very much concerned with people’s health and he offers many services along to help keep every member of your family healthier, such as offering UV Light Treatments. “UV light kills mold, mildew, and many other harmful things,” he explained. It is especially good for people who have respiratory problems, allergies, and other issues, as it creates a cleaner environment and a healthier lifestyle for the whole family. “The quality of the air in your home is critical to your family’s overall health,” he added. In addition to UV Light Treatments, they also install humidifiers and dehumidifiers in people’s homes and offices because that can also make people feel better.

Mark is very proud of his team. “They are reliable, honest, and take pride in their work.” His personal reputation and that of his team and his company is very important to Mark. His business is growing swiftly. His team and fleet of service vehicles keeps expanding and they are able to respond to more and more of the demand for their services. He has more people in training as well, making sure they are proficient and prepared to offer the same level of skill and service.

When asked why he does this type of work, Mark immediately explained how much he loves being a service tech and that he enjoys meeting new people. “It’s really good to be able to help people.”
