Jason and his crew were all great! Jason came out within a day of our contacting him, gave us a very complete overview of what was needed, caught that we would need a new zone board which the other two companies hadn't caught, and he included that in his bid. He gave us three different bids, allowing us to choose to just do a heat pump, to do a dual fuel with our gas furnace that still works well and to do a new gas furnace with heat pump. He pointed out all the pros and cons allowing us to make a decision that worked best for us. He was super responsive when we had questions and was able to schedule us the following week finishing the work in just two days. He has years of experience and we felt very confident that he knows what he is doing. We already have given his name out to a friend and they just finished today! His bid was by far the best, and we are happy to recommend him to anyone! read more

Aarvaks removed my existing 25 year old gas furnace from an extremely tight crawl space. They replaced it with 45MUHA electric heat pump with Merv 13 filter. They also descaled an existing on demand hot water system. Every staff person was very knowledgeable and a delight to engage. Staff, onsite and in office, answered every question quickly and completely. Their price was 60% of the average of other quotes. No hidden or extra fees. I trust Aarvaks and totally recommend. read more

Had issues with my heat pum. Got set up at a great price and fast service! Thanks again!

Our 25 year old whole house heater was making loud noises and was not worth repairing. Aarvaks provided timely, helpful diagnosis of the problem and offered a range of replacement choices. Jason, the new owner was incredibly knowledgeable and tailored a split whole house heat pump system that would meet our needs. Because of the short time frame before the tax credit would for heat pump systems would expire, they were able to install the system quickly. Aarvaks' pricing was competitive, and the Bosch system they installed has greatly improved our comfort and been highly efficient. I highly recommend Aarvaks. read more

Look no further--make this HVAC company your first and last stop. The work and service they provide are truly amazing. The entire team was phenomenal, starting with the office staff who promptly booked my appointment when we were without heat . Other companies were pushing us out until after Christmas or New Year's, which was completely unacceptable since our house was freezing cold. The new owner, Jason, was fantastic. He personally came out, designed the system, and took the time to explain everything in a way that made me feel completely confident in choosing Aarvaks. His knowledge, honesty, and attention to detail truly set the tone for the entire experience. The installers did an immaculate job, and I couldn't be happier. They designed a two-zone system separating the upper and lower floors--something I never even considered--which has made our home significantly more comfortable and energy-efficient since we no longer have to condition the entire house at once. On top of that, we now have cooling as well, which I absolutely love. I have to say it again--the installers were stellar. They were kind, clean, professional, and even communicated when they were taking lunch and what the next steps would be throughout the process. All in all, I am truly thankful that I called Aarvaks. They were efficient, clean, responsive, and completed my project within the year, which was a bonus for tax credit eligibility. I honestly couldn't be happier--coming home to a cozy, comfortable, and efficient house has been a game changer. Thank you all so much. I highly recommend Aarvaks. There aren't many family-owned local businesses left, and Aarvaks is one of the few. I feel truly blessed to support a local company that delivers such amazing service. read more

First off I would like to say thank you! We had some issues with our system and another company gave us nothing but false information and tried to price gauge us. Aarvaks came to the rescue, they provided us a solution which was to go with a heat pump unit and gave us a competitive price. We also had 2 other quotes just to be sure. They nailed the timeline and gave us step by step installation process. Great company! The new owner Jason also called us to thank us for the business after install. He claimed he took over the company and his goal is to put the customer first. read more

My heat pump went out in our new home. I called around to see about pricing Matt came out to take a look and confirmed it needed to be replaced. I told them I was really tight on money, the owner Jason called and worked out a great price, he told me he just took over the business and his goal is to be fair and honest. I was more than happy the install was perfect. Thank you fellas!! read more

My central furnace wasn't working so I called Aarvaks since they installed it with the previous owner. They responded quickly and the technician was a pleasant person. But he did not seem every knowledgeable and after an hour (despite the error code being clear) could offer nothing beyond that he needed to talk to his supervisor. Several days passed and it was cold so I called my former general contract and he fixed it in jiffy. Finally I got a call from Aarvaks that they wanted to come out again to figure it out and possibly suggest replacing the whole furnace. Well, by this point the furnace was fixed but I had to pay Aarvaks their visit fee. This bothered me, but they ended up refunding my fee. So maybe this just a one off experience. read more

No words. These guys were great. They not only did the job but went above and beyond to help resolve a separate but related issue. All the guys were great but Jose gets a special shout out for extra effort!!! The job was just completed a couple hours ago so so far so good. Highly recommended! read more

Aarvaks team brings quality and value. Great customer service exceeded my expectations I would definitely use them again.

I got numerous quotes from different company's and Jason was able to beat the prices and got my new unit installed same week. Was very professional and can tell he knew what he was talking about. Will definitely come back for any and all hvac needs. read more

Jason was amazing! He installed a AC Unit a few months ago! He was honest and very helpful! May I add he was cheaper than 2 local companies.

I had a appraisal for 29,880.00 for a heater. I'm a single senior on a fix income i called Costco and for a better heater I got appraisal for 14,690.00 not sure why the big difference. But please ve careful and get a second appraisal. I'm going with the Costco. This is totally to much read more

Aarvaks was great. We had to do a major update to the heating on our 100 year-old, three-story house. The plan they developed was to replace the gas furnaces that were heating the bottom two floors with a single gas furnace, and installing a heat pump for the top floor (the ducts to the top floor had been blocked off because of seismic work). The Aarvaks team came in the first week in December 2025, during the cold weather in the East Bay, and completed the work in the week we had scheduled. They have a high-quality team, including someone who specializes in the ancillary work of repairing the walls they needed to cut through. We moved back in on Saturday, and have had a fully and comfortably heated house for the first time in 25 years. We are looking forward to te summer, where we will be able to use the heat pump to provide AC for the top floor. read more

I was in need of a new HVAC system and duct work. I reached out Aarvaks and found out they were transitioning to new ownership. The new owner, Jason, came out and did my quote. He was thorough while here and took time to understand my needs. A few days later I recieved a very reasonable quote which included a rebate. When it came time to install, the installers were so nice, hard working, and very knowledgeable. They were respectful and delicate while inside the house and cleaned up very well. They completed the install within the projected time frame and reviewed the new thermostat with me at length. I strongly recommend Aarvaks for good priced, high quality product and work. read more

this was the best service I ever got on my heating and air conditioning. best job very honest rate

Furnace wasn't working, price for Aarvak coming out to diagnose was $169. A bit high, Bear charges $75 but Aarvak could come in 2 days and was faster responding to my voicemail so not a dealbreaker. Aarvaks technician came early for appointment which was ok since they called first. Correctly diagnosed broken inducer. Took off broken part and showed me the wheel inside wasn't spinning anymore. Put part back in before leaving. I appreciated the clear explanation and demonstration, so still all good. Emailed estimate a few days later, $1,200 to install a new inducer. Seemed a bit high since I had noticed the job took about 15 minutes. Found the part at Reliable Appliance Parts in Berkeley, available for pickup next day for $400. Picked it up myself, took about 30 minutes to install since I'm not an expert. My total cost $400 (the part) + $169 (Aarvak) = $569, Aarvak was $1200. Saved $600+. Would have been ok paying Aarvak but I think $1200 for diagnosis, part and 15 minute repair seemed way too high, even considering they're making 2 trips, having to pick up the part, and their overhead . I believe it was a bit greedy on their part, wouldn't a $400 markup been sufficient, for a total of $800 instead of $1200? read more

Great service and nice to work with! Thanks for getting us back on track! :) It's also nice to work with a local business.

I asked Aarvaks to service my furnace. They replaced the filter. Afterward, my furnace kept turning off and on. I called them and they returned to say I needed a new sensor and said they would order it for me. Then they called to say my furnace was so old the sensor was no longer available and I should get a new furnace which they would install: $13,000. I called another company and the owner came out. He noticed the filter was improperly installed and then that it was the wrong one and was causing my furnace to overheat and shut off. He installed the correct filter and my furnace has performed perfectly since. He also confirmed there was nothing wrong with the sensor. read more

The technician who did the heater repair did a great job diagnosing and repairing my furnace. The problem is with management and the pricing markups. The technician at the beginning of the appointment quoted me $180 for a furnace module. But then when it came time for the bill, his boss marked up the part to over $1,000. The technician was embarrassed and tried to call the boss while in my garage. I also tried to talk to him, but he wouldn't pick up. It was very awkward and unprofessional. I don't mind paying a parts markup. Even paying double the going rate on Amazon would be acceptable to me. But this markup was ridiculous. I was planning to hire them to replace my furnace later this year, but now will look elsewhere. read more

Aarvaks saved our office's broken heater! They were responsive and quick despite the high demand for HVAC services in the winter pushing back most appointments to at least one month for other local companies. The technician arrived well within their estimated arrival window and looked extensively at both the furnace and the thermostat, determining that the wiring of our thermostat was at fault. When he finished replacing it, he took the time to explain how the new thermostat works and was set up to run automatically for us during working hours too. We're so happy to not have to rely on space heaters anymore and will definitely be scheduling all future HVAC issues with Aarvak! read more

I had such a positive experience getting my heating issue diagnosed and repaired quickly and reasonably. I called a few other places before Aarvaks and then remembered they had done previous work for me. My heat stopped working completely and every other place told me the earliest they could look at it was a week. Aarvaks gave me an appointment a few days later and then called the next day when their schedule opened up. The owner Jeff was so friendly and quickly got to the root of the problem and had my heat working in no time! I will definitely use Aarvaks again! read more

I have been having an issue with my Business's A/C system and contacted multiple HVAC companies. They either would not respond or would respond and simply state that they were not interested in taking in any new clients. I called Aarvaks and a human being answered the phone and I was put on the schedule. The day of the appointment I was prepared for a no show because that seems to be how people operate these days but nope, Chris showed up completely professional. He went about his business and was extremely thorough. When he was done, he took the time to explain to me the issue that I had and even let me know that Bag Quality Construction had installed it wrong in the first place. They were fantastic and I would recommend them to anyone. read more

Glen was very honest and helpful in leading the diagnostics, and then doing the install, for the draft inducer motor for our 23 year-old furnace. Phil, who came out and did the initial diagnostic visit, was also very friendly and helpful. Recommended. For whoever may need to hear this: Diagnostics and repairs for mechanical issues of all kinds, but especially older stuff, can be tricky business. Be nice and try to be a good communicator, and it might help bring some good luck when it comes to your repair needs. read more

I never (never) write reviews, and it's taking me a good long time to do this one, but if you need assistance with your furnace - THESE are the people to call. Last winter, (told you it's been a while), my furnace went out and these guys came to the rescue, immediately. In no time, we were back on track, warm and cozy, and with a much lower out of pocket expenditure than we had anticipate. Thank you, Aarvaks. I still can't spell your name, but if we ever need this type of work again - you're the first call. read more

I used Aarvaks to install a whole house air conditioner and a high efficiency furnace. The initial installs seemed OK, but later on the furnace began dripping water inside the unit causing extensive rust. Had to have a repair person come out and tighten up a gasket to fix. The A/C condenser stopped working and Aarvaks charged me $218 to diagnose and replace a blown fuse. Two days later a 2nd sister fuse blew. I decided to replace that one myself. I plan on using Atlas from now on. read more

I called and spoke with Jeff, the owner. My need was to install a new Ecobee3 smart thermostat in a 1930's house. The wiring needed to be replaced to get the unit to function. He had done excellent work in the past servicing my heater so I knew they were the right ones to call. Due to the busy time of year, he was not able to send anyone out right away. Jeff spent a good amount of time with me on the phone explaining what was necessary and coached me though the process. I went to Pastime ACE Hardware with confidence, knowing what I needed to complete the project. My son and I completed the job in good time and we are now enjoying our new thermostat. Thanks Jeff! read more

Aarvaks Heating & Air Conditioning - Ecobee3 Smart Thermostat- compatible with Apple HomeKit - Heating & Air Conditioning/HVAC Near Me - Berkeley, California

Totally positive experience. The person setting up our appointment was knowledgeable, and as a result the serviceman arrived at our house with the necessary replacement part. Our furnace was quickly fixed. Aarvaks clearly operates with integrity and I wouldn't hesitate to work with them again. read more

When we moved into our house, there was a faint buzzing from our gas heater, and I someone check it out. He said we'd need to get a new heater, and at the tune of ~10k while we had a million other projects, we deferred. Also the heat worked so it didn't seem too urgent. Well, after a couple years in COVID, the buzzing got way worse! I called Aarvaks thinking we'd be in the hole another 10k. Long story short, they were extremely responsive and courteous, sent out someone super quick, and the guy identified that it was an easy fix that he was able to go to the Home Depot to get a part and complete the same day, all for around $300. I wouldn't hesitate to recommend them for their work and their integrity. Thank you Aarvaks!! read more

Great experience with Aarvaks who fixed my furnace. They came highly recommended from a family member that has worked with them for many years, and they lived up to the expectations. Jeff diagnosed and found a new circuit board for our old furnace and Chris installed it. Chris was very thorough in testing/ensuring it worked, and he even went out of his way to help us with a few other issues. He took the time to do everything the right way. He was very pleasant and knowledgeable and explained things very well. Both of them wore masks and booties and practiced social distancing protocols. Also Lisa the scheduler was very helpful and a pleasure to deal with. Will be using Aarvaks again! read more

I had a great experience with Aarvaks Heating & Air Conditioning. They installed both heat and air for me, and I am thrilled with the results. They listened to my needs, and provided me with exactly what I wanted. The installers were very considerate. I recommend them highly! read more

These guys are the best. When I told Jeff what I'd done to my furnace, he told me right off what the problem was and how to fix it. His advice saved me the cost of a service call and enabled me to get the furnace (now a furnace and air cleaner, very valuable just now) the same day. I wish I could have made some billable hours for them, but when the furnace goes for good they'll be my first call. read more

My pilot light went out on my stove last night, called PG&E and was informed the gas was fine. This morning my thermostat had an error message and our water heater was not working. I looked up recommended services for our thermostat and saw Aarvaks. I spoke with Glen about the issue, explaining as best as I could (which was probably very confusing) he stated he would be getting back to me so I would be seen same day to get the issue taken care of. He called back with an appointment window. Jeff arrived around 13:10-13:15 for my 13:00-15:00 window. I explained the situation and Jeff knew immediately that something was awry with the earthquake valve. He reset the earthquake valve and showed me how to fix it if the problem arose again, helped relight the water heater, checked our furnace and showed me how to use the thermostat more effectively. He was super helpful, informative and patient. For any and all needs related to heating and cooling I will only be calling Aarvaks. Thanks Aarvaks for a job well done! read more

hi, my heater went south and i couldn't remember what heating company had put it in. i called aarvaks and they were very helpful and reasonably priced. i eventually found the company that did the work with their help and since the heater was still under warranty i went with the original company. if i had to have heater work done again i would definitely go to aarvaks. read more

Great experience with this Berkeley-based, family-owned company. Our furnace died the weekend after Thanksgiving. I left an old-school voicemail that Saturday, thinking I might not even hear back, and got a call from one of the owners that Monday morning at 9am. He spent almost an hour on the phone with me, patient the whole time, having me flip switches on and off, looking at the photos I was emailing him, etc. -- basically spending lots of his time trying save me money by not having to make a housecall. We were unsuccessful, so I was scheduled for a service call. It was three weeks' wait, a minor bummer due no doubt to the time of year, etc. The tech who showed up this morning (ahead of schedule!) was just awesome: smart, competent, easygoing, happy to take my questions, wore a mask in the house, didn't try to sell me an entire new furnace when the problem was only with one part, etc. He had the problem sorted in a few minutes, and fixed in an hour or so. We are customers for life now, so glad to find a trustworthy company. Thanks again Aarvak's! read more

I'm not accustomed to give poor reviews but this one is definitely warranted given my recent experience with Aarvaks HVAC. I called to set up an appointment for service to my HVAC unit, all went well with scheduling the date/time, and the actual diagnostic appointment itself...until I get an invoice for the necessary repairs with a total cost only. I followed up with owner Jeff Geier and requested a line item invoice so that I could provide a copy to my landlord, as well as the size for the recommended replacement of the air filter on 8/16, and I have not received a response from him to date. I honestly thought that everything was handled so professionally up to that point (the invoice), that the radio silence completely shocked me. Customer service and professionalism go a long way. read more

Arrived home in Berkeley yesterday afternoon to no heat. Called Aarvaks at 3:15 pm and was given a 10-12 am window for today. Delighted at the prospect of a fix before the weekend! Chris arrived at 9:55 and did a masterful job of diagnosing and fixing the problem. Jeff the owner came over to consult and we were delighted with the whole experience. I love that the company name is Finnish for "guess who?" read more

My new heater was so noisy that I couldn't hear the phone or TV when it came on. The installer and the contractor shrugged and said there was nothing they could do. Aarvaks came out, looked at it and gave me a quote to insulate the intake box and other parts. It really helped!! They are creative problem solver, and also very professional and knowledgeable. Now I have a normal heater.Just a great company! read more

If I could give it NO stars I WOULD! Here is the letter I wrote to the owner/service person- basically they are crooks, dishonest and NO ONE should ever use them!!!!!!!!! To: Jeff Geier Aarvaks Heating I am writing you because of the inspection you preformed at my residence. You arrived on Monday 1/17/2011 for a service call. I stated to you that the heater is only blowing cold air. You stated you had to "see what's going on" and began working. Upon further inspection YOU stipulated that the furnace was "no good", "too large for the home", "wont fire up at all"- (though it was firing up prior to your arrival), "and that basically it's no good and you need a new furnace". I repeatedly asked you "are you sure it is NOT just something simple like an igniter switch?!" You insisted that NO, it is not; YOU cannot even get power to the furnace, which again was not the case prior to your arrival. We had power, just no hot air. Having been a Realtor for 6 years and also going through some remodels in my day, I felt that the information you were giving me seemed a little peculiar. I felt the way in which you were speaking to me seemed condescending and at times untrustworthy. So I decided to get a second opinion. I called Harry Clark, an extremely reliable and reputable company. They arrived on Wednesday. The first issue they came up with was that YOU had taken ALL the wires off the control panel, disconnected everything and basically left it in that capacity. THERE was NO reason for you to do this OTHER than trying to support your own diagnosis that there is no power. YES no power since YOU disconnected the wires. The second finding, ONCE ALL THE WIRES HAD TO RECONNECT WHICH TOOK OVER AN HOUR TO DO, was that the furnace WAS firing up, up until the point that the furnace needed to ignite, and then would not, causing the furnace to shut down. Harry Clark diagnosed this as a "broken igniter switch", ran ALL safety diagnostics and ordered the part. Harry Clark arrived yesterday, changed the igniter switch and the furnace is now WORKING again. They also went through every duct, every wire, and every switch to ensure everything was safe, running properly and it was. They even explained things we could do to help the life of our only 10 year old high end, Trane furnace. YOU on the other hand I guess saw a mom, living in the hills, who was upset she had no heat and decided to take me for a 12,000 dollar ride to get a new furnace rather than actually taking time to help the simple problem of the igniter switch. YOU decided to try to use words you felt may scare me into giving up and buying a new furnace like "safety, fire, problem etc," rather than being an honest person and stating that maybe you weren't familiar with this type of furnace. YOU also left everything in utter chaos to only further support your bogus diagnosis which caused me more money in labor from another company. Shame on you for treating customers this way; I will make sure I share my experience with other colleagues and friends to ensure that you never set foot in a home of a person I know or work with. JEFF- I see your comment However its even more sad that I was referred to you by a colleague- You did not preform like an honest respectable way. We can go back and forth ALL day. I NEVER agreed with you for the record, my statements were one worded, "okay", as you went down all of the items you thought were wrong and justified me needing a new furnace. The most interesting to me is that Harry Clark found NOTHING you speak of- "no leaks, no safety issues" nothing- but they did find the 68 dollar igniter. That's a big difference from 12,000 dollars don't you think? I understand you have been in business that long- and frankly that's what scares me. read more

Aarvaks recently replaced an original Aarvaks furnace which had been installed in my house in the 1930's. The new installation went smoothly. I found Jeff and his crew to be knowlegeable, honest and easy to work with. The cost, including asbestos removal, was reasonable and I look forward to lower energy bills this winter and for more winters to come. We are happy with our new unit and are happy to have relied on Jeff to keep our family warm with the new furnace. I also love supporting a local, family business! read more
