Ken Kloster is the owner and founder of Five Star Power Systems Heating and Air Conditioning (AC). Ken began his career in heating and AC as a student at Rets Technical Training Center (Rets). After graduating in 1999, Ken began working as a certified heating and air conditioning technician. Ken spent ten years in the field doing service and installation work before embarking on his own venture.

In 2007 Ken founded Five Star Power Systems Heating and Air Conditioning. He kept moving the business forward by remaining focused on providing a service that was reliable and consistent above all else. By focusing on delivering the same high quality service day in and day out, Ken established himself as being efficient, trustworthy, and exceptionally dependable.

A solid foundation of trust formed and became the foundation of the business. By earning respect and making clients a top priority, Ken has been able to take Five Star Power Systems from a one man business to a highly respected commercial and residential HVAC company.

From the company headquarters in Millersville, MD, Five Star Power Systems Heating and Air Conditioning has quickly become one of the most respected businesses to operate in Anne Arundel County, Howard County, Baltimore County, and Baltimore City. The company now runs several crews throughout the region. All of which adhere to Ken's business philosophy and customer focused mindset.

Under Mr. Kloster's guidance the company is set to continue establishing great client relationships and achieve continuous growth.

Water Heating

They make everyday tasks like washing our hands and our dishes pleasant. They aren't thought of often. We are all busy and grow accustomed to them working for us without hassle.
