The Most Trusted Heating & Air Experts in Northern Virginia

SSI is a Full-Service Mechanical Contractor in Virginia (VA)

We specialize in creating comfort through indoor heating and air conditioning. Founded in 1979, SSI remains committed to the values that have helped us grow from a small family-owned service business to a leading Northern Virginia residential and commercial HVAC contractor.

Still family owned and operated, SSI is now the trusted mechanical contractor for significant commercial enterprises, including Dulles Airport, and we bring indoor comfort to a large number of loyal residential customers. We do it all with an unwavering commitment to quality, timeliness, and value that have been part of our mission from the beginning.

VA Residential Heating & Air Conditioning Service & Repair

Your indoor comfort is paramount to us. When you’re at home, the last thing you should worry about is your heating and air conditioning system failing. Whether it’s a cold winter or hot summer, your home should be exactly the temperature you desire.

When you choose SSI to handle the installation and maintenance of your home’s heating (furnace) and cooling system, you can take confidence in our work. How are we different? Our highly trained air conditioning and heating service professionals conduct periodic check-ups on your home’s systems so that we can catch potential failure before it happens. And if you’re ever in need of emergency services, you can be assured that we’ll have a technician at your home, any time of day.

Our residential technicians provide full-service to all brands of HVAC equipment for air conditioners, heat pumps, air handlers, furnaces, thermostats, furnace repair and accessories such as filters, air cleaners, humidifiers and air treatment products.

Contact us today and experience the SSI difference for yourself. Whether you have a commercial operation and need a system for a multi-million dollar project, or are looking for service on the air conditioner in your home, our team is here to make you comfortable indoors.

Commercial HVAC Service & Maintenance

Our commercial customers choose us for the same reasons our residential customers do: quality and service. We understand the importance of keeping valuable equipment at a constant temperature -- and we know how to do it. Likewise, we know that if an HVAC system fails (or doesn’t perform well enough), a business risks facing unhappy employees and customers.

Our professional team provides full-service to all brands of HVAC equipment, including piping, pumps, ventilation, boilers, IAQ, BAS, controls, mission-critical systems, CRAC units, emergency service and repairs, maintenance programs, replacements, retrofits, tenant fit-outs, supplemental systems, design, and engineered projects.

No matter the size of your commercial HVAC project, you can have confidence that we’ll handle it with professional expertise and in a timely manner.
