    The installation team did a great job! They were punctual and the service provided was excellent! We reviewed the details of the job and answered any questions I had thoroughly and what to expect after installation was completed. Both gentlemen were respectful and kindly mannered. They cleaned up after themselves and left no mess at the end of the day. They were detailed in sharing any additional information necessary and photos of the new furnace since it was located in the attic. We reviewed instructions and use of the new thermostat and downloaded APP. My experience was positive from start to finish. My needs were met and the furnace seems to be functioning properly since installation. The entire team, from the owner to the installers, were on the same page, which made for a smooth experience. I confidently would recommend Associated Heating & Air. Thank you for your service!

    We were hearing noise whenever heater comes on before the hot air comes out through vents. My husband stopped by the office to report the noise. 1st Choice Heating & Air Conditioning sent a technician right away to our house. The technician tested few things and explained what might be causing the noise. After testing the air intake he decided to installed a muffler for air intake to stop the noise. He was very knowledgeable and was able to fix the source of noise. After installing a small muffler, the heater unit doesn't make noise. We are very impressed with the technician ability to fix the issue in a timely manner. Thank you for your customer care. We are very satisfied with their response.

    Heat Pump InstallationAC Repair & InstallationGas Furnace ServiceFree EstimatesLicensed Contractor

    Our old furnace had been giving us trouble for a while, constantly cycling on and off due to electrical issues, making it clear it was time for a replacement. As is wise move for any major home improvement, we sought bids from three different HVAC companies to ensure we made an informed decision. Air Blue HVAC truly stood out. Their initial inspection was the most thorough, and the options and alternatives they presented for replacing our system were comprehensive. Sergei, the representative who conducted the inspection, was incredibly professional and friendly. He patiently walked us through his findings, explaining everything from simply replacing our gas furnace to installing a brand new heat pump system. I appreciated that he explained the pros and cons of each alternative, breaking down the technology in clear, layman's terms. He spent a lot of time with us, never once making us feel rushed or pressured into a sale. After our discussion, Sergei left, giving us plenty of space to consider the information and make a decision that were in line with both our budget and needs. While Air Blue's pricing was competitively in the middle of the bids, they offered significantly more in terms of better equipment and additional work, making their proposal the best for our needs. After consideration, I called Sergei to schedule the installation. On the day of the installation, we were introduced to a second Sergei and Vadim, all part of the team. All three individuals were friendly, highly skilled, and worked together seamlessly. They each worked on specific tasks with efficiency, handling the installation of the outside air conditioning unit, the inside air handler, and the duct work. Their attention to detail was excellent; every step was executed cleanly and properly, reflecting great pride in their work. Despite working incredibly hard throughout the first day, they were happy to show us their progress from time to time and explain various aspects of the installation. By 7:30 PM, they had accomplished a tremendous amount, completing the air handler and outside condenser unit, and even a portion of the duct work. The following day, they finished the remaining duct work, started up the entire system, tested everything, and thoroughly cleaned all the work areas. Before leaving, Sergei reviewed all the completed work in detail and provided a clear explanation of how to operate our new system. Satisfied, I then paid for the project. I could not be more happy with my new system. Our home is now very cool and comfortable. Our previous main problem area; the upstairs master bedroom, once uncomfortably warm, with little airflow has been transformed to a nice cool area due to the new unit and the much improved duct work. I also like our new smart thermostat that enables me to control its features from a wall display as well as my smartphone. I highly recommend Air Blue HVAC for all your heating and cooling needs. Their work is competitively priced, and they operate with honesty and integrity, providing straightforward estimates without any phony discounts (unlike one company that included my credit card rewards and federal incentives as part of their "savings," which were entirely separate from their service). Sergei and his dedicated team deliver a high-quality, professional installation and truly stand by their work.

    I've relied on Fuse HVAC several times within the last 5 years and they have always done excellent work The latest project involved all new furnace, AC and duct work for the main house and a heat pump AC/heat unit for a studio sized space. Eric did a great job of provided multiple estimates/options as we evaluated different possible systems before honing in on our final choice. Andrey managed the install from start to finish, kept the crew working efficiently and made sure everything was done correctly (including coming back to fine-tune a few areas of the installation). Fuse handled everything including the city permits and meeting the inspector for the final sign off. All was done as planned and no surprises between the estimates and invoiced amount. They were very prompt, professional and maintained a high quality of workmanship. They also communicated often to keep us informed of the schedule and were flexible when certain days wouldn't work. As someone who helps with property management and repair I've deal with many different companies and contractors over the years. My usual experience tends to be less than satisfied but Fuse HVAC makes sure you are more than satisfied. Highly recommended!

    I vet companies that I deal with as thoroughly as possible. One Season Heating & Air-conditioning Are former SoCal Air Flow Pro's from Chad the Owner To Aubrey a lead Tech, Rebecca ( Office Manager) & Sydney (Customer Service) always exceeding my high expectations. Rebecca the office manager was super responsive to my requests/ questions. She never dismissed any of my extra concerns, and even made sure that they were addressed to my utmost satisfaction. Sydney in Customer Service possesses professionalism and a great interpersonal skill set which IMO - a true asset for the One Season Team Tysm Rebecca & Sydney ! Aubrey the lead technician is very experienced and skilled. He showed up during the time range provided to me, and called beforehand to provide me with an ETA. He even put on booties when entering my house! Also, I find the entire One Season Team to be trustworthy. They never tried to upsell or fear monger like Triton or Goettle who used their Acquisition of SoCal Air Flow Pro's to gain entry into my home to try and sell me plumbing and inspection services (Customer Beware!). I schedule for a HVAC check up and they send me a plumber who states the HVAC associate will call in a few days and bever did! One Season is a unicorn in today's service business: exceptional and skilled employees, honesty and fair pricing that does not prey on homeowners at their moment of vulnerability. Wholeheartedly recommend!!

    I recently replaced the entire HVAC system in my home and obtained three quotes from different vendors, including Costco. I did my best to compare apples to apples, even though each company carried different brands. After carefully reviewing all proposals, I chose Irvine Air Conditioning & Refrigeration Inc., and I’m very glad I did. Their proposal was exceptionally clear, detailed, and professional. Their pricing was fair and competitive. Communication throughout the process was prompt, courteous, and straightforward — no pressure, no sales gimmicks. Once I signed the agreement, they scheduled the installation right away. The crew, led by Stanley, did an outstanding job. The workmanship was clean, organized, and clearly done by people who take pride in their craft. I highly recommend Irvine Air Conditioning. They deliver excellent service at an honest price, and the entire experience was smooth from start to finish. Thank you, Irvine AC.

    We knew there was trouble when our furnace started pumping smoke out of the vents. I contacted Metz and they had someone out the next day. Jorge was amazing, showed me pictures of what things looked like in the attic where the furnace and a/c unit were. He was super knowledgeable and able to tell me exactly what year each part had been installed. The furnace was well over 25 years old, so it lived a good life. He broke things down as to what I could replace and what I should replace, along with different cost options. The system was ordered and installed within 3 business days. The main installers were Andrew and Mando and they were scheduled for 8am on Monday and they arrived a little before then, ready to work. Andrew was amazing with our dogs in the backyard and made friends with them in no time, making the install even easier. Jake and Josh came in soon after to help with the huge task of disassembling the old system and putting in the new one. It took all day, and our home and outside was left exactly like they found it. Andrew stayed late to show me the Smart Thermostat and walked me through the app so that I can now program our heat and a/c on my phone. I have used Metz numerous times before and they never disappoint. I highly recommend them for your heating and a/c needs.
