"Victor showed up on time, and was pleasant. He removed the old fan and then assembled and installed the new fan. Even overcoming a problem with a part supplied being the wrong size. Great job."

"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."

"Guil's assistants installed the air conditioner in the window on Monday, June 6th, and did a good job, cleaning the window and removing the old AC. Guil came the next day and took away the old AC and caulked up the gaps in the seal on the new AC with his caulking gun. Guil was very courteous and upbeat about the install. We hope to use him again on a future project."

"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."
