Hassler Heating and Air Conditioning, LLC

I recently was looking for some assistance with replacing and moving an exterior AS unit. After interviewing 3 AC specialist providers within my area, I finally selected Hassler Heating. This was based upon the general consultation experience, price and reputation. I selected Hassler Heating and worked with Bob Dickson as my lead. From start to finish the experience has been excellent. Bob is extremely professional and knowledgeable and he came out as scheduled with his colleague Derrick. They proceeded to remove, move and re-install and new exterior AC unit in about 4 hours. Their work was very clean and I couldn't be happier with the results. Their price was extremely competitive which when mixed with their quality will keep me as a Hassler customer for a long time to come. When reading about AC units and pros and cons, most folks seem to consider the installation professionals to be as important if not more important than the unit itself. I would certainly recommend Hassler to any of my close personal friends.

I love the mini-split they installed and have maintained over the years. We use it all the time for both AC and heat. And the repair technicians who come out are always knowledgable and professional.

Bruce was the best technician we've ever had. He was knowledgeable, professional and most importantly trustworthy! He repaired our heating/AC system when the day before another company told us we needed to replace our entire system at the cost of approx 15K! We signed up for their maintenance plan and will keep Hassler Heating and AC as our vendor of choice forever! Thank you.

I have used Hassler Heating for two of my Berkeley homes.
We had a complete heating system installed in one home. We met with many different local companies and decided on Hassler because they were the most professional, reasonably priced, and fit us in quickly. The installation crew was very proficient and pleasant. My tenets and I are very happy with the new system. The job went right on schedule and they even came to meet the inspector after the job was finished. I also used them for work on a broken water heater on my other home. The service technician came quickly and was able to diagnose my problem. They came back and replaced the part as soon as possible. I would highly recommend this company for both installation and service.

We chose Hassler to install our new furnace, because they offered the Carrier modulating furnace at a great price after the PG&E Energy Upgrade California Rebate. This was our first big expense as new homeowners and we were nervous about the process. Hassler did a great job, and we are very happy with our new furnace. Each person from Hassler we interacted with was courteous and professional, from Andrew who talked us through the process and helped us understand various trade-offs, to Keith who took thorough measurements and identified important considerations with our particular home. Manny and Caesar performed the installation, and this was a large and complex job including new boots for the registers. They did fine work, taking care not to damage the original wood in our old house. Manny came back the last day to put the final touches, and we are impressed with the result. Hassler has been a great company to work with.

Thanks to Joannie at the Hassler front desk, we got fast 2-day service for a dead heater on the coldest day of 2023.

Hassler was efficient and responsible in every way possible. The installation went smoothly and on time. The person who came to check the furnace did a good job. They did all the paperwork and I already have my refund from the energy credit. Pleasant straightforward pleasure to work with them.

The service technician was very professional. He provided excellent customer service.

Working with Hassler Heating couldn't have been a better experience. The were able to schedule an appointment promptly to repair my furnace. My tech Chris was prompt, courteous and very professional. He diagnosed the problem and made the repair quickly. I would happily use Hassler again for any heating or water heater need, and highly recommend this local business.

We bought a house built in 1948 with a heater that was installed when the house was built. We contracted Hassler to come in an completely overhaul our home, put in a new HVAC unit, remove asbestos, install new ducting, and finish everything off with a brand new Nest! Hassler was professional grade from beginning to end. When you work with Hassler you work with the best. They worked through a number of tricky issues with my install and were there for me every step of the way. They were always available day and night via phone and guided me through the entire process. The end result was amazing and we are loving our comfortable new home! Oh yeah, and I have a nice rebate check coming my way from PG&E due to my new energy efficient home. Thanks Hassler!!!
