Hassler Heating and Air Conditioning, LLC

Replacing my gas furnace with a new heat pump system. It's a lot of effort and time to research and expensive to convert. But the furnace is 50 years old and tired. Got several estimates. Asked a lot of questions and finally hired Hassler HVAC for the job. Shout out to Matthew Mays who did the initial review and prepared the bid, Berkeley Choate who did the pre-install inspection, and the front office staff who kept things going. They patiently answered all my questions and kept me in the loop every step of the way. It gives me confidence that the installation will go well. Stay tuned. Update: The Install is complete and we couldn't be happier! It wasn't easy fitting new tech into a 100+ year old house but they did it with graciousness, expertise, and humor. From the estimator Matthew, to pre-install inspection and project management by Berkeley; the installation team of Soa, Jose, Lee, & Brian; the electricians Brandon and Diego; the follow up by Tony and then Jesus; and Adela and others in the front office who kept things moving -- a big thank you! I would not hesitate to recommend Hassler to others who are converting from a gas furnace to a heat pump system. Five Star service and execution!

We had an excellent experience working with Hassler Heating & Air, especially Rich Flores. Even though we ultimately decided not to move forward with the project this year, I still felt strongly that they deserved a review because the experience was that positive. Rich was incredibly professional, patient, thorough, and honest throughout the entire process. He came to our home multiple times, spent significant time walking us through the issues, answered every question we had, and never once made us feel pressured. He took a very thoughtful approach and helped us understand not just what was wrong, but why. What really stood out to me was how detailed and methodical their process was. They approached the project in phases, explained tradeoffs clearly, discussed long-term planning, and helped us think through comfort, efficiency, future HVAC replacement considerations, construction impact, and budgeting. It felt much more like working with a consultant than just getting a sales quote. Even though we chose to wait another year before making this investment, Hassler will absolutely be the first company we contact when we are ready to move forward. That says a lot. I would highly recommend Hassler to anyone looking for a professional, knowledgeable, and trustworthy HVAC company. And if possible, ask to work with Rich Flores. He was fantastic.

Hassler has been providing annual maintenance for many years. My home of 25+ years was built before the SF earthquake of 1906. I have had two contacts in the past week, one for maintenance and one for a new installation. They were both comfortable to work with, took many photos (and even audio!) of my unit in the crawlspace, explained the issues clearly, taught me a lot, and I trust them.

All my interactions with Hassler, its staff, and its employees have been excellent. Today’s visit by technician Robert Coates—to check the health of the heat pump system Hassler installed in 2024 at my home—was no exception. He arrived on time, quickly understood my concerns, and was undaunted by the challenges of the site. Robert was smart, personable, thorough and efficient. He took videos of each component of the system and showed me that everything was working properly and “looking good,” which was reassuring. As the system is still under warranty I wasn’t charged for this inspection. I’m happy to recommend Hassler for their superior customer service, integrity, and quality. As Robert said, “it’s a good company.”

Hassler was fantastic to work with, from get-go when we made our initial inquiry. Our house was built in the 1960’s and had no central air so we needed to have a mini-split system installed from scratch. Hassler explained the entire process, provided timely and accurate estimates and a walk-through where our sales person Kenneth came to our home, performed a detailed inspection, really listened to what we wanted and provided options and solutions. Once we agreed to the project, Hassler quickly had a project manager/team leader do a second, more technical inspection plan onsite. He was also great. Then they sent the install team out days later for the three day project. The install team members (and there were many over the three days, depending on which aspect of the project—electrical, wiring, etc—was happening were all polite, on time, a pleasure to work with and very friendly. Our project turned out great, and we couldn’t be happier. Thanks Hassler
