Meet the Team
Johnson & Johnson Heating, Air Conditioning, and Plumbing has been a trusted family-run business in the Eastern Panhandle of West Virginia for over 27 years. Founded in 1988 by Michael and Susan Johnson alongside their son Jason, the company started from their home, initially providing HVAC services to help with family finances and Jason's college tuition. As the community's reliance on their dependable work grew, Jason found his calling to work full-time with his father and serve the area he's called home for decades. After his parents began transitioning to retirement in 2012, Jason took the helm with a clear vision: to elevate industry standards by combining advanced technical skill with genuine, reliable customer service. Today, the company remains locally operated, licensed to work in West Virginia, Pennsylvania, Maryland, and Virginia, and is committed to solving the heating, cooling, and plumbing needs of Martinsburg area homes and businesses with a neighborly, expert approach.
Frequently Asked Questions
My home in Martinsburg has uneven cooling, with some rooms much warmer than others. What could be the cause?
Uneven cooling is a common issue in our area, often stemming from improper HVAC system sizing or ductwork design installed by previous contractors. Our certified technicians start with a comprehensive inspection of your entire system. We assess ductwork for leaks or poor design, check refrigerant levels, and evaluate if your current unit is correctly sized for your home's layout. For Martinsburg residents, we often find that correcting these underlying installation issues resolves the temperature imbalance and improves overall efficiency.
Do you offer maintenance plans for both HVAC and plumbing systems?
Yes, we provide scheduled maintenance for both heating/cooling and plumbing systems. Our HVAC maintenance helps prevent breakdowns, maintains efficiency, and can extend the life of your equipment—especially important with our local temperature swings. For plumbing, our inspections can identify small issues like minor leaks or wear on water heaters before they become major problems. As a locally-owned company serving the Eastern Panhandle for over 27 years, we design our maintenance plans to provide peace of mind and long-term reliability for your home.
I need a new water heater installed. Are your technicians certified for that work?
Absolutely. Our team includes certified technicians specifically trained and experienced in water heater installation and repair, whether you need a traditional tank model or a tankless system. We handle all aspects of the job, from safe removal of your old unit and proper disposal, to precise installation, gas line or electrical connections, and thorough testing. Our long history in the community means we understand the water conditions in Martinsburg and can recommend the right model for your household's needs and budget.
