We highly recommend Hassler Heating and AC. Three years ago, we updated our system with a heat pump. The installers were professional, efficient and responsive. Hassler has been performing the annual maintenance. They always confirm appointments, arrive on time and have the nicest technicians.

My first experience with Hassler Heating and I am very happy with the service. Technician Steve arrived and promptly assessed the problem. He was able to resolve the multiple issues and have my system running. Thank you for taking care of me!

The consultation on HVAC installation was good. The representative answered all of our questions and we learned a lot. However, in comparison with other companies, Aarvaks failed to provide an itemized estimate claiming that they "have to follow (CA) State guidelines/rules". Not sure which guidelines/rules prevent a privately owned company from providing a detailed quote. I suspect there simply no such guidelines or rules. Regardless, we ultimately decided to hire another company who were much more transparent and cooperative (in fact out of 6 companies that we received estimates from, Aarvaks was the only one what provided us with only a lumpsum estimate). Giving them a 4 star review because the representative seemed knowledgeable, and over all scheduling of the visit was alright and we received an estimate pretty promptly. Cant's speak of their work obviously.

We had an issue with extreme excess condensation in our A/C unit. The technician arrived today and spent well over 4 hours resolving the issue and performing maintenance, he was professional, knowledgeable and courteous. When the time arrived for the invoice, this too was pleasant, a most fair price. This is a wonderful locally owned company, glad we called them.

These guys are an absolute joy to work with and I wouldn’t use anyone else. They are communicative, accommodating, knowledgeable, and professional. I have hired them for at least the last 15 years.
