Sinclair Air Systems installed a mini-split in our ADU last month. Crew showed up on time, did clean work, and finished in one day. They were honest, fair, and knowledgeable. Would use them again.

My family and I woke up to a broken AC system, which later became 87 degrees in our home. Our unit is probably 35 years old and Sinclair Air Systems could have easily tried to up sell us. Instead they replaced the condenser and added 1 pound of refrigerant and fixed it quickly. They will always have our business!!!

Had Sinclair install a new AC system at my place in La Verne and Im really happy either way how it turned out. The crew was on time, super helpful, and got everything done in a day. They helped me pick a system that made sense for my budget, and it cools way better than my old one. Everything was clean and professional definitely recon them if you need HVAC work around La Verne.

had a new HVAC system installed by Sinclair Air Systems and couldn’t be happier. From the initial estimate to the final installation, everything was smooth and professional. The crew explained my options clearly and helped me choose the right heating and air conditioning system for my home. They showed up on time, did quality work, and cleaned up after the job. If you need an AC replacement or full HVAC install, I highly recommend them.

Sinclair Air Systems has been our go-to for years. They are the absolute best! When we have temperatures in excess of 100° and no a/c, it’s a problem. Sinclair Air is incredibly responsive, professional and efficient from beginning to end. They are thorough in their evaluation, making sure to properly assess and diagnose the issue. They treat their customers like family and it truly makes all the difference.

Sinclair Air Systems did a great job installing our new HVAC system in Upland. Fast, professional, and reliable. Highly recommend for anyone needing heating and air in the Upland area!

Sinclair air is a great company. We actually bought an air conditioner 21 years ago from them, and it was still going, but we wanted to upgrade it. We had such a great experience back then, so we decided to go with Sinclair again. They have great customer service, we got a good deal, and the workers were great! Overall, we are so happy with our new air conditioner and furnace!

We were referred to Sinclair Air by our property manager and they were great! Rick and Susie were informative and helpful. They diagnosed the problem and took care of our AC issues in about 24 hours.

After years with an HVAC system we enjoyed, we decided, after 22 years it was time to replace the furnace and condenser. We called Sinclair Air System’s and spoke to the office manager, Susan. She was very professional and knowledgeable. She scheduled an appointment for us with the owner, Rick. He explained to us the unit that will fit exactly what we needed. Giving our approval, work started the next day, remove the old A/C and replaced with a new state of art unit. We are completely satisfied with the work done and pleased with our new Air Conditioner Unit. Thank you Rick and your crew at Sinclair Air Systems for your professional approach and assistance. Just know, when assistance is needed in the future you will be our first call.

We've been using Sinclair Air over at Monstrous Pizza for the past 11 years. Reliable. They do what they say they are going to do and their service is top notch.

Well let me start by thanking each and everyone of you(Rick, Susie, Miranda, Steve, Billy, Anibal, Dennis, Todd, & Darin) for making my experience with Sinclair Air systems clearly preeminent. They are 90% complete and I love what they have done. The pride & attention to detail Rick and all his crew put into their work is very hard to find when working with multiple craft. It is clear to me at Sinclair Air Systems Rick sets the bar for excellence, and his team easily surpasses that bar. I will continue using Sinclair and will recomend to eveyone I know.!!!!!! Update .3/26/17 Sinclair Air systems is now completed with the installation in my home. My wife and I could not be happier. This is a company that goes the extra mile to get things done correct.

If you use Sinclair Air systems you a guaranteed good prices, excellent work, & great customer service. DO NOT GO ANYWHERE ELSE! YOU WILL BE SORRY!

Sinclair AC is awesome and they are now my go to AC company. I contacted them when my AC when out during an awful heatwave and they were able to get a technician out to my home same day. The office staff was super friendly, professional and efficient. When the technician arrived he was also friendly, professional and knew what he was doing. He quickly identified the problem, had the part in his vehicle and repaired my AC in less than an hour. The price was great. Thank you Sinclair AC! I give you my highest recommendation!

Spoke with Susie, awesome lady there! Caitlin you as well. Tech showed up at 0800ish, even though my AC unit is a bit old, he was able to complete the routine maintenance and refilled the refrigerant . MANY MANY thanks to Sinclair Air for coming out. I know you guys are super busy, again, thank you!!

I had been putting off a new system for years and finally pulled the trigger. Through a friends recommendation I called Rick. Rick came to my house and explained all that I should be doing in an honest manner. He gave me a price for the complete system and never once had to change his price. I got top of the line service and products and my system runs so well my kids have to tell me to turn it off because I like it cold. Great relationship with the owner Rick and his crew that was clean and always on time. I give them a 10+ Thanks Rick

Outstanding Customer Service! Dealt with consummate professionals every step of the process. They were able to squeeze me in on short notice and kept me apprised of the technicians arrival time. The technicians were punctual, professional, polite, and fast! Excellent pricing as well. Thanks to Emily, Greg, Carlos and Susie for taking care of my ac issue. Would not hesitate to recommend them to anyone.

Even though it was a hot day with many calls before mine, Sinclair Air Systems made it out to my mother in-laws house same day and fixed problem. As my mother in-law is elderly having the air working was very important. They did a great job and a fair price.

Sinclair Air Systems did a great job putting a new heating/air conditioning system for our home. Rick, Suzzy and crew did a fantastic job.

My air conditioner was not cold. I asked them to repair it. I asked for a leave of absence and waited at home. They finally arrived. After two hours, I went to check it. People left early and didn't say anything. A few days later a bill for the inspection fee of $145 was sent. Called to ask and no reasonable explanation was given. I don't recommend getting them to fix it.

Rick and his team installed an AC in my condo. They were responsive each time I called, and they did a great job. Thank you, Rick, from Angela in Pasadena!

Excellence customer service Rep by the name of Susie. Very honest and helpful. I would only call this company in the future for any Air Condition issues or. concerns. Thank you very much City of Covina Angie B
