My Lennox furnace stopped producing heat and showed a pressure switch error. The technician from…read morethis company came out, looked at the system briefly, and the only solution they proposed was a full system replacement. There was no real diagnostic process -- no proper checks of the venting, pressure switch tubing, airflow, or basic furnace operation. They simply concluded that the furnace needed to be replaced, which would have cost thousands of dollars. I decided to get a second opinion and invited another HVAC company. They actually took the time to diagnose the problem and were able to fix it without replacing the entire system. This experience was extremely disappointing. Recommending a full replacement without proper troubleshooting is not acceptable. I would strongly suggest getting a second opinion before agreeing to major repairs.

Thank you for the fantastic work at my parents' house! The technician, Mando, was very…read moreknowledgeable, professional, and polite throughout the entire process. My dad had a very old furnace, and we had been spending a lot of money on constant repairs. After finally finding Badger Heating & Cooling, everything changed. Mando took the time to explain our options and suggested installing a new Mitsubishi heat pump. We decided to move forward with it, and we absolutely love it! The new unit is efficient, reliable, and has already made a big difference in comfort and energy savings. Most importantly, my dad is very happy with the service and the results. I highly recommend Badger Heating & Cooling to anyone looking for honest, knowledgeable, and high-quality HVAC service!

I had to replace a very old gas furnace in my home. I received a very high quote from another HVAC…read morebusiness based on the age. I like to stay local, so I contacted Golden Bear HVAC. The quote I received from them was much more reasonable. They did not try to add extra fees just because of the age. There was also no sales pitch or them trying to get me to enter into a service contract. The service techs from Golden Bear (Alberto and Daniel) showed up on time and were very respectful of my home. They always wore booties and completely covered my floor for protection. They worked diligently and completed the job in the time frame I was told. I received timely estimates and receipts from Bertha at the main office via email. She was very responsive to all of my requests and questions. I received text messages with updates and arrival times to include a picture of the technician. I am more than satisfied with the new system and I will continue to use Golden Bear in the future for all of my HVAC needs.

Angelo the tech who was in charge of the installation is completely incompetent. He outright lied to me about fixing something when he did not wire up a sensor. He installed things incorrectly. Angelo left the screens to the crawlspace open so rats could go inside. I would never use Golden Bear again. Tamim's advice was poor at best.

They were quick to identify several issues with our previous unit and went above and beyond to make sure everything was done right. Brayton was especially friendly, knowledgeable, and patient, taking the time to answer all of my questions and explain what they were doing. They even stayed late to finish the job so we could have our HVAC up and running the next day. The quality of their work was excellent, and their pricing was very competitive. I would highly recommend Hahn Mechanical to anyone in need of HVAC work!

He walked me through all the options clearly and provided multiple quotes at fair, reasonable prices. We ultimately decided on a full upgrade, installing a new heat pump system, replacing the gas furnace with an air handler, and redoing all the ductwork. Brayton and his team went above and beyond, delivering a clean, well-executed installation with great attention to detail. The end result is a quiet, highly efficient system with outstanding airflow. I wouldn't hesitate to work with Hahn Mechanical again and highly recommend them.

Come August 24, 2026 and a heatwave forced me to turn on the AC only to find out the system was not cooling down. I notified Stephan and he referred me to a third party AC maintenance company ( Vicente) . Vicente notified me that he was not going to come over for no money since according to him , Stephan owed him tons of money for clean up work on bad installations by Fadi and crew. I told Stephan and he then referred me to a different guy named Juan which took 2 days to come out and the only thing he did is confirm that there was a leak and charged the system back up with 2 pounds of Freon. A closed loop AC system correctly installed never leaks an ounce of Freon , let alone 2 pounds!! I asked Juan to tell me where the leak was coming from but he did not and simply left . I had to call another company to come out and diagnose that the the leak was at the flare fitting of the suction line of the outside heat pump. I repeatedly called and texted Stephan ( a week and a half now) to come over and fix the leak as there is a contractual warranty on labor of two years , but to no avail. Iam simply being ignored. Horrible service, and I decided to escalate this by reporting Alanis air to the state license board . I bet there are many other dissatisfied customers and I would urge them to do the same. Seems to me this is an unscrupulous business in it for a quick profit with disregard of customer well being and disregard of contractual obligations!
