Get matched with top thermostat installers and replacers in Simi Valley, CA

"Mr. Avery called me and knew what I needed. He came out and was here in 15 Minutes. Mr. Avery was happy to give a free estimate, when everyone else that contacted me was not. Most others wanted a minimum of $80. to $90. Mr. Avery made a call to his Business and made sure they had the Part in stock that I needed. When he returned, the part was installed within an hour. He stayed to make sure that everything was safe and worked as intended. He was very professional and had a good sense of humor. I recommend 'Just Be Cool Supply' to anyone who needs Furnace repair. Mr. Avery is a Licensed Professional and the price was very fair. I will call them again if needed. Thank you Mr. Avery."

"⭐️⭐️⭐️⭐️⭐️ Integrity truly lives up to their name. We had them replace our entire HVAC system and also install a split system in our guest house, and the experience was excellent from start to finish. The team was professional, knowledgeable, and very easy to work with. They showed up on time, explained the process clearly, and made sure everything was done right. Replacing a full HVAC system can feel like a big job, but they handled it smoothly and kept everything organized and clean throughout the process. The split system they installed in the guest house works perfectly and was a great solution for the space. What really stood out was their honesty, attention to detail, and the pride they take in their work. It’s refreshing to work with a company you can truly trust. I highly recommend Integrity to anyone needing HVAC work and will absolutely call them again for future needs."

The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."
