D.B. - Douglaston, NY


"The entire experience was effortless and worry-free. Brendan was extremely knowledgeable about the ductless heat and A/C systems and helped me choose the unit that would work best in my 3-Car garage. The installation crew arrived on time and completed the install in a neat and professional manner. The unit is very easy to use and it worked wonderfully to keep the garage cool this summer, turning a former "hot box" into a pleasurable space to complete projects. I will definitely use T.F. O'Brien again and highly recommend them to anyone in need of HVAC services. "
