“Rapid response, the technician gave us all the details and fixed everything promptly.“

“Needed a plumber on a Sunday after my hot water stopped working and my natural gas detector went off. Called and Mniska was at my house in 30 minutes. He came back the following day to replace my hot water heater and did some other fixes as well.
Personable yet professional and was very clear in all communication. He was patient and kind as well. 5 stars!“

“3rdGen installed a VRF heat recovery system in our 5000 square ft office. They are experts in design build and have done a great job in our Mitsubishi installation. They also installed Lauren Cook ventilators for our office kitchen and bathrooms.“

“Jerod was very experienced and had a good attitude. He overcame a few issues and kept us well informed. He was respectful and a great representative of Kruse.“

“We had a ductless mini-split system and heat pump hot water heater installed. During the whole process, they were helpful, friendly, and easy to work with. Super happy with the results!“

“Sergio was very knowledgable & polite. He was able to clearly explain the status of our current system & help us understand what we needed to do next. We have contracted with Aarvaks to have a new system installed. We've paid a $1000 down payment to start the process.“

“These guys do a great job, especially on older systems. They’ve been maintaining several properties for me for over six years now. I recommend them to all my clients.“

“I had high hopes with Cooper & Hawkins given their long history, but my experience was frustrating. While they offer HVAC and refrigeration services, their communication was poor and scheduling felt disorganized. I waited longer than promised for a technician, and when they finally arrived it seemed like they weren’t fully prepared to diagnose the issue. Prices also felt high compared to the actual work done. Some staff were polite, but overall I left feeling under‑informed and let down by the process. It didn’t match the level of professionalism I expected from a longtime contractor.“

“The blower motor broke on my Carrier Infinity furnace and they were able to get the motor the next day in Concord and changed the unit for me in Oakland. It was also covered under warranty even though they did not do the initial installation. When it comes time to change the unit I would use them.“
