We had our A/C go out in our office a week before a 90-degree, week-long heatwave. Controlled Air Systems came out, ordered everything we needed and had our system replaced by the beginning of that heatwave. Very knowledgeable, and scheduling is very timely. System is working great and everything was at a great price. Thank you, Controlled Air Systems!

Highly Recommended! We recently used this team to replace our existing HVAC system with a new heat pump, and I cannot recommend them enough. From the start, their expertise with heat pump technology was incredibly impressive. They took the time to explain the entire system and how it works in a way that was clear and easy to understand, which made us feel completely confident making the switch. The team also went totally above and beyond for us. Not only did they notice and notify us about a necessary repair in the attic, but they also took on the additional work of installing a vent hood for our new microwave. They were fantastic about working around our tight timeline, and their customer service was friendly, helpful, and direct throughout the entire process. The crew was efficient, respectful, and left the workspace perfectly clean. I would absolutely use them again for future projects!

Josh Kurmel has been very responsive, forthcoming, and helpful as we explored the possibility of replacing our gas furnace with a heat pump for cooling as well as heating. His team installed the indoor and outdoor units in a couple of days and tied them into our solar-electric system to keep it ON if there’s a grid outage. It came online just as our first heatwave hit and we’re very glad of it. Josh also helped us navigate the rebate application & permitting processes, which will give us a 16% discount when all is said and done. We’re very satisfied with Controlled Air Systems and recommend them highly.

I have been a customer for almost 20 years. I value their talent in fixing my very old furnace…it is still running! And their honesty regarding how to proceed. I have spoken to other services who “sell” rebates by increasing their rates. When we buy a new furnace, it will be with Josh.

The draft inducer motor on our Bryant furnace went bad, so the furnace would not come on at all. We appreciate the professionalism and quick response that we received from Controlled Air Systems. Repair tech Justin was able to acquire and install a new motor in short order. All good now. The cost of the repair was not cheap, but considering Justin had to make two trips to our house and also handle the logistics of acquiring a new motor, I would say that the price was fair.

Josh and his team did a wonderful job installing new air pump in my house. It was a great service from the very beginning to the end of the project. High quality advice on what kind of air conditioning I need in my house expaining all possible options. The process of installation went very smoothly with the attention to every detail. It was also a very good support and help on how is better to use the system installed. We went through the very hot summer, and it was a very comfortable feeling in the house. I am very happy with everything.

I’m so glad I chose to have my AC repaired by Controlled Air Systems Inc. From start to finish, they were true professionals who knew exactly what they were doing. Initially, I reached out about an electrical issue and spoke with Josh, who referred me to one of his contacts—also incredibly helpful. I hadn’t planned on fixing my AC since it had been broken for years, but since I was already on the phone, I figured it was worth getting it checked out. Justin came by to inspect the system and quickly discovered a massive leak in the AC coil—a manufacturing defect. After researching my options, he walked me through them without any pressure, helping me weigh the pros and cons of repair versus replacement. The pricing was fair, and I chose the best option for my budget. A few weeks later, the part arrived, and Justin took care of everything, ensuring the system was properly fixed and refueled with refrigerant. With the hot Gilroy summer ahead, I’m looking forward to finally having a working AC again! If you're in need of HVAC services, I highly recommend Controlled Air Systems Inc. They serve the entire South Bay and are based in San Jose and Gilroy.

I am delighted with the mini-split system I bought from Controlled Air Systems. Josh gave me excellent advice as to the size and placement of the unit and Jose and the rest of the crew did an expert job of installation, going over and above expectations in leaving the site pristine.

We had an exhaust duct with an abnormal amount of condensation dripping. After multiple calls with no response to the company that installed our HVAC system, we were referred to Controlled Air Systems by our general contractor. Justin, one of Josh’s employees at Controlled Air, responded to my call the same day, set up an appointment, showed up on time (actually, early), determined the reason for the condensation, and resolved the issue on the same trip. We will not hesitate to contact Controlled Air Systems for any future hearing or air conditioning issues. GREAT experience!!

Josh came recommended by a neighbor. We asked for an onsite visit to discuss the possibility to replace our central AC’s outside unit and install a separate AC for one room that’s not part of the central AC system. Josh did an extensive onsite review, discussed different options, he spent a lot of time trying to decide where to run wires and install the outside units for the balance between aesthetics and costs. The process from initial review and final installation took only two weeks, all the jobs were done within 2 days. We are very happy with our decision to go with Josh and his crew, the new systems are so quiet and energy efficient.

Controlled air systems came out to our home and provided us what we believe to be a fair estimate to install an AC system and whole house fan. The job was completed In a timely manner. The installation team was professional and friendly. They were very thorough and clean.. I would highly recommend controlled air systems!

I would recommend Controlled Air Systems to all. I was in need of a HVAC company to take care of an extreme issue immediately. Justin was out the next day. Justin resolved the issue right there. I have now signed a contract for all 16 of my commercial buildings. This is how much faith I have in this company. Highly recommended.

I think I was grossly overcharged. All what was done is specialist checked the level of freon in my AC which was good. And told me to change air filter because it was dirty, which I did myself. For that I was charged $220. For about of 10 min work.

My experience was beyond all I could of ask for! The company as a whole from Josh to all the employees on my job were great in every facet of their responsibilities. People great, work done great (dialed in), I'll hire them again with my next property. This company has "old school values" they do the job right! They take pride in their trade. Thank you Josh and crew! Ed

I am thrilled with my new HVAC system installed by Josh and his team. My old system was a nightmare - uneven heating and cooling, and just overall uncomfortable. I knew I needed a complete overhaul, including new ducts, registers, and replacing the A/C and gas heater with a heat pump. After researching, I had my heart set on a Mitsubishi heat pump and found Josh, a Mitsubishi Diamond Contractor. From the start, Josh stood out from the other contractors I got bids from. He took the time to patiently explain exactly how he would install the system, answering all my questions thoroughly. A lot of places will send out a sales guy that knows the product but not how it's installed but Josh knows exactly what he's talking about. He even worked with me to choose adjustable registers and grills that perfectly complemented my home's aesthetic. Now, after several months and experiencing both winter and summer weather, I can confidently say my house has never been more comfortable. The even temperature distribution and efficiency of the new system is incredible. Josh's expertise, patience, and dedication to customer satisfaction are unmatched. I highly recommend him to anyone looking for top-quality HVAC work.
