Ariston Heating & Cooling - Orinda's Emergency HVAC Services

For refrigerant leaks, our licensed technicians perform precise diagnostics to locate the source and recommend a permanent repair or, if the system is older, discuss high-efficiency replacement options that use newer, more environmentally friendly refrigerants. To address indoor air quality, common in our area, we offer solutions like advanced air filtration systems, UV light purification, and humidity control integrated into your HVAC system. We focus on fixing the root cause to improve your home's health and comfort.

We treat every installation as a custom project for a neighbor. It begins with a free consultation to assess your home's specific needs and discuss options, including high-efficiency heat pumps or dual-fuel systems. As an authorized dealer for American Standard and Mitsubishi, we use premium equipment. Our schedule is flexible to ensure we never rush the job—we complete thorough testing and ensure you're fully satisfied with the performance before we consider the project finished.

Yes, we service and repair all makes and models. While we specialize in and are authorized dealers for American Standard and Mitsubishi, our technicians are trained to diagnose and fix issues on any system. For repairs, we always use high-quality parts and provide honest advice on whether a repair is the best solution or if an upgrade to a more reliable, efficient system would be more beneficial for your Orinda home in the long run.
