"The entire process from beginning to end was seamless. Lisa and her team provide excellent communication on the project throughout the entire process. I couldn’t be happier. Originally, I just wanted the house painted, but it turned out we needed to replace some wood siding and Pablo did an excellent job. Pablo is phenomenal and is a perfectionist. I am so thrilled and happy every time I go outside to look at my home. We even had new windows installed- Lisa facilitated the process for the new windows and it was an excellent experience overall. I would hire them again and actually I plan too this fall when I need some additional help on the outside of my home. Excellent pricing,excellent communication, top-notch service. They cleaned up everything which was a huge plus! We recently got a new puppy that was walking around the backyard and in the house and they treated her like family :) they went out of their way to ensure nothing was on the ground and everything was cleaned up, so there was no stress for us or the puppy."

"I had a great experience with Prestige AC in Feb. 2025 when they replaced my entire AC compressor (outside) and variable speed air handler (attic). They were very knowledgeable about current SEER II standards and took time to explain quality vs. value. With inflation raising the cost everything, they worked with me on selecting the right unit for my house at an affordable price without the high pressure sales. Their extra customer care made the whole experience shockingly pleasant. For instance, they performed scuttle hole remediation after they went into the attic. They even updated my service disconnect, added a surge protector, and switched the fuse. Lastly, they installed a ecobee thermostat which I can now use to control the unit remotely through wifi. This has already saved me time and money. The unit works great so far and just in time for the AZ summer heat! Ask for Travis."
