Sergei is the best. He told me exactly what was wrong with my 21 year old air conditioner, and recommended several options for replacement. I chose the single cycle because it was the most affordable. Installation of the new AC and heater was great. The workmen cleaned up, and Sergei was there to make sure everything went ok. Would recommend them. read more

Our excellent customer service began when discussing our project with Sergei, who was not pushy on sales or services, just gave us honest thoughts about our particular system needs for our very old, inefficient and broken HVAC. We ended up with an all new heat pump system that is quiet and really efficient (17.5 SEER2). We already anticipated need for a new system since every tech that came in last 5 years said it was on its last leg, before it finally died during an extreme heat warning. The installation crew arrived on time, were very respectful of our garage items (helped move bikes to backyard and even used cloths to cover from the sun!), never complained about the working conditions (hot garage and tight garden area for fan unit), and were informative about the process. They also left our property very clean and tidy upon job completion after a single (and very hot) day of installation. As a bonus, I was not expecting the excellent craftsmanship of the lovely stainless platform cover over the new plywood they cut-to-fit for the removal of the old/damaged platform/box deck, and they used duct-board and sealant to finally make the interior of the intake under the unit sealed from all the walls and dust generation that has been blown throughout the home since the 1970s. Could not be happier with the end product as well as the process from inspection/quote to system startup. I would recommend Air Blue HVAC to my mom, friends/family, and to you! Give them an opportunity to earn your business as they offered us the best price on the best system. Thank you, Air Blue HVAC team! read more

After getting quotes from over 10 of the highest rated HVAC companies on Yelp and Google within my area, I decided to go with Air Blue HVAC for my AC installation. Prior to the installation Sergei took the time to inspect everything, explain my options, and answer my questions instead of just doing a quick walkaround and sending me a quote. On top of that, their price was one of the best I received. They quoted me a premium system for about the same price several other companies were charging for basic entry-level equipment. Sergei and Vadim showed up early and worked tirelessly through a 90+ degree day. They even cleaned up and fully restored my furnace closet, which hadn't been touched in decades. Their workmanship and attention to detail were outstanding. Even after the installation was finished, they stayed past sunset to properly test the new heat pump. Since a new system needs time to run before you can verify temperatures, pressures, and check for refrigerant leaks, they didn't rush the job. Watching the care they put into testing and fine-tuning the system reinforced something I learned during this process: even the best HVAC equipment is only as good as the installation, and they made sure everything was done right before they left. What really impressed me was the attention to detail. Sergei took the time to perform a Manual J calculation to make sure the system was sized for my home instead of just replacing my old unit with the same size, which most of the other contractors wanted to do. They also completely air-sealed the return, built an elevated platform with river rock underneath so I can add pavers later if I decide to, and were very respectful of my property throughout the installation. They also backed their work with a 3-year labor warranty, while most of the other companies I considered only offered two years. Overall, I couldn't be happier with my experience. From the initial consultation to the final installation, Air Blue HVAC consistently went above and beyond. I'm confident I made the right choice, and I wouldn't hesitate to recommend Sergei and his team. read more

They were so consultative and helpful throughout the entire process! Highly recommend this team! read more

I was in need of replacing my old ac system and ended up choosing to go with a heat pump. I appreciate Sergei taking the time to explain the process and different units with me. I felt very comfortable with my decision to hire his business and the units he recommended. Everything went very smoothly and professionally. The installation went flawlessly, very impressed with their workmanship. Everyone was very courteous. They showed me pictures of the installation in the attic and walked me through what they were doing. The work area was cleaned up afterwards and I am very happy with my new system. It's quiet and efficient. And holding up well with the heat wave. I want to thank Sergei and his team for a fantastic job and peace of mind I did the right thing. Thank you so much! read more

*Update* Had my system installed by these pros exactly 3 years ago and unfortunately during the heat wave the AC stopped working. So i gave the team at Air Blue a call and they offered to come check it out that day but i was unable so they said ok we'll be there first thing next day. Sergei showed up early in the time frame and fixed the issue in minutes. This was not an install problem or a hard part issue just a fluke wiring thing. I learned that they prioritize loyal customers that have purchased their products during these extremely busy times Thank you all again for the amazing service!! I will sleep well tonight. read more

We recently bought a house with no air conditioning and a furnace from 1964. We had a couple companies come give us bids on for a new system. Air Blue came in as the most cost efficient, but more than that, Sergei at Air Blue was the only one who took the time do explain why his quote was what it was. He explained why each step of the process was necessary. His team did a super clean install, even putting the furnace near the back of the attic so we could still use the spot near the access point for storage. Definitely recommend! read more

After getting four estimates, I decided on Air Blue for my elderly parents second upstairs system to replace. They were timely, neat, and double checked their cleaning up before they left and had the new system in in 17/18 hours over two days. Vadim and Sergei #2 were great. In the future my parents will need a larger Hvac system to replace their main one and I'll be definitely contacting Sergei #1 and his team again. Thank you Air Blue. read more

The crew/team from Air Blue HVAC is very professional, hard working, efficient, knowledgeable, courteous, and friendly. Every step of the way, they explained what was being done and what would be needed for any future maintenance. Our old A/C unit was removed and disposed. Our new A/C that was installed works great and efficiently. The location of our furnace air filters was changed to more accessible return cavities, we no longer have to reach for them in the attic. We are so pleased!! Steve & Bobette work completed, 10/07/26 read more

Great communication before appointment and on time. Sergei is very friendly and explains every step. Get attention to detail.

After 35 years, my old Gaffers & Sattler A/C finally gave out, so I reached out for several referrals and bids. After meeting with Sergei at Air Blue, I really appreciated the time he took to explain my options, especially for my condo, and to walk me through what they offered compared with the other bids I received. I decided to go with Air Blue, and I couldn't be happier with that decision. They showed up on time, were extremely professional, clean, and took the time to explain the process and answer all my questions. We did have a small glitch with the thermostat placement, but they didn't hesitate to come back and make it right. I really appreciated their professionalism, responsiveness, and commitment to getting the job done right. They were referred to me by my boss & I would highly recommend Sergei and the Air Blue team to anyone in need of a new HVAC or furnace system! read more

We had a great experience with Air Blue HVAC! Sergei and his crew installed an AC Pro Series Z heat pump system for us, and they were terrific. They're a small, family-owned business, and we really appreciated the personal attention and care they gave us. Everyone was conscientious, polite, pleasant, and very efficient. They showed up when they said they would, kept everything clean, and somehow managed to get the entire installation done in one day! Their pricing was competitive, but one of the things that really helped us decide to go with Air Blue was that they offered to sound-insulate our intake, which is located in the closet where our air handler is. That extra attention to detail really stood out to us. The whole experience was easy and stress-free, and we're very happy with the new system and the work they did. It's nice to find a small local company that takes pride in their work and treats your home with respect. Highly recommend Sergei and the Air Blue HVAC team! read more

Quick update... We've had our Air Blue A/C for over two years. We love it. It is efficient and keeps our house super cool. This summer I noticed a slight vibration coming from our condenser outside. I called the office and Sergei came out the next day for a free check! He diagnosed it immediately. A plastic ring inside was vibrating. It was an easy fix, and he was on his way. These guys are the best and continue to impress. read more

Sergei and his team are top-notch. They offered competitive pricing, great service and great warranty as well. They worked hard to install a brand-new AC and furnace and even included some extras that would normally be charged as extra work by other companies. From the initial quote to clean up they were very professional and did a very clean job. I would recommend this team to everyone to be honest. read more

Experience with this company was awesome. We were notified when Sergei was in route. He arrived very timely at the start of the appointment interval. He was very gracious about me "hanging over his shoulder" and watching him work. He not only did not mind; but welcomed it. He identified the issue quickly and explained each step he was taking and why. He did not try to "upsell" us on a bunch of ridiculous stuff we didn't need as many other companies do. But he did make a few pointed suggestions and explained exactly why he was suggesting those things. He made the repair quickly and efficiently and had us back up and running in short order. Great experience! We highly recommend this company. read more

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. read more

We recently had to replace our old gas furnace and AC system. Sergie clearly explanded the pros and cons of the options and we made our decision. Several of our neighbors have had great experience with Air Blue so we we're hopeful for a good experience. I'm happy to say that Sergie and his team Vadim and Sergei were top notch and enjoyable to work with. We have a 99 year old house that deserves quality craftmanship and attention to detail and that is what it received. We're fortunate to have been referred to Air Blue HVAC. They are knowledgable, happy to explain and detail oriented. The whole process of installing our new electric heat pump and basement airhandler was seamless from start to finish.

Our AC stopped working, and we knew it was time to upgrade our entire HVAC system and replace the ductwork--plus we wanted to get it done in time to qualify for the federal rebate. We interviewed five different companies, and Sergei from Air Blue really stood out. He was incredibly knowledgeable, patient, and thorough in explaining all our options and how the system works. Sergei was always available to answer our many questions, and on the day of installation, the crew was professional, efficient, and did excellent-quality work. They took the time to explain everything and left our home neat and tidy afterward. Sergei even came back later to educate us about asbestos remediation, which we had questions about from another company--he went above and beyond. When the city inspector came for the final check, he was very impressed with their workmanship. We highly recommend Air Blue for any HVAC needs--great service, great people, top-notch results and good value! read more

It was time to replace our 40 year old central AC and Furnace. We obtained 3 quotes for a variable speed heat pump and it seems all the HVAC companies we got quotes from are offering the ACPro Brand which allowed us to compare apples to apples. Air Blue was the most reasonable of the 3 quotes for a 3 ton system. Sergei the owner was very responsive to my many questions before we decided to go with them and they were able to scheduled the install on the dates we requested. Turns out Air Blue had done an installation a few houses away a while back. I went to talk to the neighbor and he told me he had a really good experience with Air Blue and highly recommended them, and that helped us make the decision to go with them. The 2 Techs, Vlad and Sergei (different Sergei) who came to do the installation were professional and very efficient. Vlad made sure to explain to us how the system works in detail, and answered all our technical questions. Drop cloth was laid down everyday and cleaned up at the end of each day. It took 2 days for the installation because they also replaced all my old ducts in the attic riddled with holes and tears, and every air vent grill in the house. The other Sergie installed the new ducts. A new nest thermostat was also installed. We now enjoy really good flow of air into all the rooms in the house. Another thing that make Air Blue stand out from the other HVAC companies is that Sergei never tried to sell me an annual maintenance plan. When asked, he said we would save money by just buying and changing out the air filter once a year ourselves, and the warranty is will not be affected. We have used many contractors for a number of large home improvement projects, and we had a really smooth and good experience with Air Blue, which is not always the case with home improvement projects. I highly recommend them for any HVAC work. read more

As new parents with an infant at home, we are extremely cautious about the quality of work being done in our house. After comparing five different companies, we chose to go with Sergei from Air Blue--and it was an easy decision. We couldn't be happier with the outcome. On installation day, Sergei, Vadim, and another Sergei arrived right on time and took the time to walk me through every detail. It was immediately clear that they are passionate about their work and genuinely care about their customers. Not only did they meet our expectations--they exceeded them. Throughout the entire process, the team was friendly, respectful, and happy to explain everything in detail. What really stood out was their openness to questions. Rather than brushing them off, they welcomed my curiosity and took the time and extra efforts to address every concern thoughtfully and thoroughly. I observed the work closely, and it was clear they took a professional approach--no shortcuts, no sloppy fixes. Everything was done the right way, with quality and safety in mind. I highly recommend Air Blue to all my neighbors and friends in the SoCal area. Thank you, Sergei, Sergei, and Vadim, for your excellent service--keep up the great work! read more

Update: Two years after install, one of the parts in the system stopped working due to a rare malfunction. Sergei came out to inspect the system even earlier than scheduled, fitting us in between appointments. They got the part and came out two days later to do the replacement. The whole thing took less than three hours, and the guys were extremely efficient, respectful, and professional. Plus, the parts and labor were completely covered by the warranty, so we paid nothing.

Sergi came and educated me about the newer ac units available nowadays, how they work, and what options were available. He was very patient, knowledgeable, and detail oriented. He was not pushy and was willing to answer all my questions and trust me i have a lot of questions. Vladim and Sergi#2 worked very hard to install the system and make sure everything was functioning properly. They were all courteous, polite, and kind. Especially with my son following them around. They worked close to 12 hours to get the system completely installed. Sergi was also there both at the beginning and end of the install to make sure everything was completed correctly. The details that i really appreciated: 1. Relocated and shortened the existing outdoor copper line and power cable, so that the least amount of it is exposed to the elements. 2. Moved the oil filter to the inside unit so that it is protected from the elements as well. 3. Opened the fins on my air intake gate for maximum airflow and also sealed the air intake box. 4. The neatness and organization of how everything was installed. I appreciate their hard work and dedication to service. Thank you AIR BLUE HVAC read more

Last summer we made the decision to scrap our 60 year old furnace and add AC to our home by switching to a heat pump and adding solar panels. We read all the Yelp reviews, everything Reddit had to say and watched all the youtube videos. We were particularly impressed by the straight forward videos by Sergei from Air Blue and called him for an estimate. Sergei spent 2 hours with us detailing what could be done and all the options that were available. Over the next months we called several times and asked questions or sent pictures of what we were thinking of doing; Sergei was always helpful, never pushy. In November we asked him back for a quote on what we wanted and got one that was quite reasonable. We mentioned that we were going to add solar and needed to upgrade our electrical panel; his suggestion was that we should wait until that was done and then call him. Electrical panel finished and we were able to hide the heat pump wiring in the wall rather than have another ugly conduit on the house (Thanks, Sergei). We called and said we were finally ready and Sergei and his team of yet another Sergei and Vadim arrived a few days later. He scheduled the asbestos removal team on Monday so he knew he would be able to finish the job without leaving us with a heatless weekend. These guys are PROS, know exactly what they are doing and worked 10 hours each day (and I mean worked). We're a bit on the picky side and they satisfied our every want. They were polite, considerate, worked cleanly and quietly; a pleasure to have in our home. All three inspectors remarked about how professionally the work was done and everyone who has seen Air Blue's work here hasA remarked about how nice it looks, how quiet it is, and how great it works. Thank you Sergei, Sergei and Vadim. read more

Sergei and his team were great! Sergei went over my existing system in detail to diagnose the problem, and explained everything that was going on. We settled on a new system, and discussed options. There was none of that upsell pressure you sometimes get in these situations, just a discussion of options. Installation came about a week later, they were here for a long day and it was all done. No need left behind either! New unit, some ducting and a couple of new vents to improve airflow. Price was good too, better than the first guy I called. I would definitely use Air Blue again. read more

Amazing HVAC company! Sergei came to my home after I started having issues with my AC. He spent so much time inspecting and explaining in detail what was going on with my unit. It unfortunately had to be replaced. Sergei gave me multiple options, and did not pressure me at all into placing an order. In fact he offered to credit the service call toward the purchase of a new AC, if I decided to go with his company. Two months later, when I had the same problem, I called him back and placed an order for a new unit. He still honored the credit for the service call after two months. The crew of Sergei and Vadim were so professional and efficient. I was so impressed with their work and detail to cleanliness. The installation, testing and clean-up was impeccable. I recommend them to anyone looking to replace their AC Unit! read more

Absolutely recommend! I had read through the reviews prior and after meeting and working with Sergei and his team, I'm very happy that we decided to go with Air Blue. When Sergei first came to do the estimate, he was very thorough in explaining exactly what needed to get done for our HVAC to be functioning properly. He was honest and gave us all of our options, provided the pros and cons based on the needs of our home, and left it us to decide. His team - Vadzim and another gentleman named Sergei - were very respectful of our home and cleaned up at the end of each day, which I really appreciate. They did a fabulous job putting the unit together, it's very quiet, and working well. You won't regret working with Sergei and his team! read more
