About Us

BAIR Necessities is a Maryland-based HVAC, Air Conditioning, Heating and Geothermal installation and repair company blending old-fashioned service with cutting-edge green technology. Owned and operated by husband and wife Terry and Karen Bair, BAIR Necessities provides sensible, cost-effective solutions to heating and cooling for both the private and commercial sectors. BAIR Necessities’ experienced, licensed technicians can handle all of your heat pump, gas, oil, hot water, air conditioning, heating and radiant HVAC system needs.

BAIR Necessities is one of the few companies that has been installing Geothermal HVAC systems for over a decade. Owner Terry Bair recognized that green technologies were the future of the industry, and he became one of the first technicians in this area to become certified in the installation and maintenance of Geothermal systems. After earning the rare Geopro certification, BAIR Necessities is truly the local expert on all things Geothermal.

BAIR Necessities has a commitment to environmentally sustainable practices, and will help you save money and save the environment at the same time. Using ENERGY STAR rated systems and the latest Geothermal technology, we have partnered with the top brands and industries to bring you both unparalleled green services and incredible value.

What BAIR Necessities’ customers appreciate most about Terry and Karen, however, is their genuine concern for their best interests. Simply put, the Bairs are good, spiritually-based people who let their actions bear witness to their core values of honesty and fair dealing. Terry lives his values by always being available to his customers. “You never know when a customer will have an emergency, and you would be surprised how often customers tell me that I’m the only HVAC guy that they can get a hold of,” he said. “It’s a lot of work, but it’s the way I would want to be treated."

“This is not what we do,” Karen said, glancing at Terry with a grin, “it’s who we are.”
