Our Customer Reviews

"Just had a replacement system put in yesterday. It is a big investment and no one wants AC unit problems. This company was professional. Our AC unit quit; it was a 14-year-old unit. It took them half a day to install a complete system and it works great. They call you back right away, they stay connected with their arrival times, they are prompt with their quotes. A very clean operation, fast, quality product. I recommend them."

"Thank you, Koontz for professional services rendered over the past 12 years. I have met many of the technicians and my experience has always been positive. The tech is cordial, open to answer questions and explains anything relevant to the functioning of the unit. This was my experience with Anthony today, who arrived on time and went about inspecting the unit in a systematic manner. I felt very confident about his ability to do the job. Thank you Anthony "

"I just had my 1st visit after our new A/C and heating system had been installed. The guys were thorough and explained items on the Nest 3 thermostat. I would highly recommend Koontz Heating and Air Conditioning."
