Best nest installation pros near Upland, CA

"100% recommend very professional, after installation they clean up everything too highly recommended"

"Danny is awesome to work with and will get you the best deal he can find for your job. The guys are professional and prompt. They do A+ work and I would highly recommend them for any kind of work you may need completed under their profession. They installed our ac unit , perform routine maintenance and we are now getting attic insulation installed next week."

"Monty does excellent work. I needed a window AC installed which involved some custom fitting and mounting. I have a sliding window from left to right instead of up and down so to do a clean install was more involved than a traditional up down sliding window. I believe Monty went above and beyond to make sure the work was quality and addressed all my concerns. He made sure the whole installation was well sealed off using generous amounts of silicone.I highly recommend him for any handyman work you might need accomplished."

"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."

"Pedro was cordial and professional and gave me options on replacement thermostats that was easy for me to operate."
