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.
