Igor was friendly, knowledgeable and finished the work quickly, and had a great chat. Highly recommended.

Maksbuilder replaced our aging AC equipment. Maksym was on time for the estimate, was polite and knowledgeable about AC systems. He understood well what I was looking for. He provided an estimate with 3 options by the time he promised. The estimate was a reasonable price. We discussed some additional options and he was very responsive and flexible. The install was done promptly and completed within one day. His team were polite and friendly. I'm very happy with the results. The AC equipment is very quiet and the install looks clean and professional. read more

Maksym is so good at what he does and even better at explaining it to me, someone who doesn't know anything about why my AC stopped working. I really appreciated the time he took to inspect the unit, even going onto the roof to look at the condenser. He did a great job laying out what needed to be done and gave me my best options to get it handled. I highly recommend him and his company! read more

I highly recommend Maksym for any issues with your system. He arrived on time and got right to diagnosing the problem. He explained the issue and fixed it quickly. He didn't try to recommend any unnecessary work. I really appreciate an honest job well done! read more

I reached out to multiple AC service companies and Maksym was the quickest to reply while also offering extremely affordable pricing. He was able to come within 48 hours and provided exceptional service. He was thorough in everything he did and gave me a comprehensive diagnostic on my AC unit. I highly recommend reaching out to Maksbuilder for all your HVAC needs! I will definitely be reaching out when it's time to replace my AC unit. Thank you Maksym! read more

Maksbuilder - Replacing my old filter for the new one! - Heating & Air Conditioning/HVAC Near Me - Lake Forest, California

Maksym was great! Super friendly, on time, very responsive, and explained everything clearly. Made the process easy and stress-free!!

Maksym is a lifesaver. Literally my HVAC had to go out on the hottest day of the year today at 6pm. I have two toddlers that I have to try to get to bed in an 85 degree house which is impossible. Used the project tool on Yelp, he reached out quickly, and was available this evening. He came over, and luckily it wasn't a parts issue and got my system up and running. His pricing was more than fair for a late night service call. Definitely will use him again for my maintenance and HVAC needs. He was also very friendly and polite. Thanks again Maksym for saving the night and working late to keep my kids comfortable while they sleep. read more

Five stars for Maksbuilder! They fixed our flame sensor issue quickly and didn't even charge me for it since it was a simple cleaning. They were professional, punctual, and very knowledgeable. I will definitely be using them for all our future HVAC needs! read more

Maksym came by to inspect our furnace after it started making noise shortly after we reached out. He quickly identified the issue as a problem with the blower motor and gave us an honest assessment, especially considering the age of our HVAC system. He also provided detailed quotes for various replacement options in case we choose to upgrade in the future. Unlike many other companies that charge a diagnostic fee just to assess the problem, his inspection was completely free. I would definitely recommend his services to other homeowners in the area. read more

Maksym went above and beyond to not only troubleshoot the issue with our AC on a weekend but also help us get into a new system. Our system was over 25 years old and finally gave out. He and his team were here within a couple days the new system. He and his team were very polite, used drop cloths from the front door to the furnace and always wearing booties in the house. It's never a good time to have to buy a new airconditioning unit and but I felt fotunate working with Maksym as he was honest and seemed to have our best interest in mind. I would definitely recommend he and his team. THANK YOU for the great job!!! read more

I interviewed several HVAC companies, including Maksbuilder because of a recommendation from my nephew. Maksbuilder submitted three proposals to replace our HVAC system and repair existing duct work. The proposal was detailed and the price was fair. We asked for a specific brand of AC unit, and Maxim quickly amended his proposal to accommodate our wishes. We scheduled the start date and their team was right on time and worked tirelessly for two days to complete the job. We are very satisfied with the results. Maksbuilder has our strong recommendation! read more

I cannot say enough good things about Maksbuilder. Right before the long Labor Day weekend, I found myself in a tough spot with no AC. I called, and within 45 minutes Max came out, did a thorough assessment, and walked me through my options. He didn't try to upsell me, just gave me honest advice and a very fair deal. What impressed me most is that he and his team showed up the very next da on a Saturday of a holiday weekend because they knew how hot it was going to be and wanted to make sure I was taken care of. They worked tirelessly all day to get everything installed and running. Afterward, they took the time to explain how everything works step by step, answered all my questions, and made sure I felt comfortable with the system. They were professional, kind, and genuinely cared about helping me, which is rare to find in this type of business. I wasn't asked to write this review, but I truly want to because the level of service, honesty, and integrity they showed deserves recognition. Highly recommend Maksbuilder!! read more

I've had a great experience with Maksym--super easy to work with. No pressure or upselling, just honest service at a reasonable price. They took the time to explain what needed to be done and got it fixed quickly. read more

Great experience installing a new AC system with Maksbuilder. Maksym is professional, polite and easy to communicate with. Both the repairing and new installation quotes were competitive. Installation was done nicely and the work site was cleaned afterwards. We are very happy with the new AC system, and would recommend Maksbuilder to others! read more

Maksym came the same day, so polite and professional.... and honest! So glad he's the first one I called, anyone else would have charged me so much more. AC unit wasn't working at all, he fixed it so quickly and was honest about there not being a big problem. I will definitely call him again and would recommend him to anyone! Thank you!!! read more

Excellent and honest service and pricing, no upsell but recommended opinions for the future based on equipment over 20 years old! Made AM appointment, Igor came by and fixed the capacitor and motor on our ancient Lennox heat pump, will definitely use them again in the future! Highly recommended! read more

Igor was very professional in diagnosing our furnace issue and told us and showed us we didn't have leak. Said we didn't have sediment trap and installed one w new gas line. read more

They did a great job. They were on time. They were very knowledgeable. They were very thorough. I am very pleased with their work.

I have had 3 interactions with Maksym, 2 consultations and an A/C maintenance service. He is kind and honest and fair. He is always communicative and timely. I trust him and his team with my house and I hope to continue working with him in the future! Thank you! read more

Maksym came out (he told me he was the owner of this company). to evaluate the condition of my furnace and air conditioner. I will be the first to admit that he was not necessarily dressed in a professional-looking uniform or carried booties with him. (We take off our shoes in the house, so that gesture is appreciated.) He just had a very simple, mellow, no-nonsense vibe about him that I really appreciated. He fairly thoroughly tested both systems, but unlike others, did not charge anywhere from $69 to $89 "diagnostic" fee. Which I greatly liked. Also, when I asked other technicians, "So, how long do you think my furnace and the air conditioner will last given its current condition?" They would hem and haw and refuse to answer. Look, I get it, you don't want to say that it will last 2 years and have it fail in 6 months, nor be accused of trying to falsely drum up business by saying, "I don't think this furnace will last you this winter.", but Maksym, told me that he didn't think the air conditioner would fail this summer, but that it was a matter of time before it died. I appreciated his willingness to answer, and I am not a customer who would get angry at him if the AC happened to die this summer and leave a nasty review saying, "He said it would survive the summer!" To be clear, I did not have Maksbuilder install or repair anything, and my rating of this company is solely based on Maksym's demeanor and the work he did diagnosing my air conditioner and furnace. read more

Maksym is exceptional in his service. He delivers timely, at a fair price, and with professionalism. I recommend him to anyone looking to get a good diagnosis of his AC problems, and looking for a quick but effective solution. read more

Maks is a rare find. Prompt, professional, Free estimate & diagnostic. He's got a tool box to diagnose the problem with a vent attached thermometer to assess if the furnace or compressor is working. He gives a detail report of the problem, fans, thermostat, furnace, or compressor. Unfortunately my compressor died and can't be revived. I don't have the money now to replace. But I would recommend Maks for your HVAC. He's the perfect high end craftsman type for your project! read more

I called this HVAC tech late (after working hrs) when my AC quit. He showed up in under an hour and got straight to work. He explained what was wrong in plain English, fixed it on the spot, and didn't try to push anything extra. Fair price, quick service, and super easy to deal with--definitely my go-to from now on. read more

Maksym was very helpful. He came to check our AC and was honest about what was needed. Everything was straightforward and easy. Reliable and helpful service! read more

Our A/C was dripping out our overflow valve over our front door every time we ran our unit. Maksym was in the neighborhood so we stopped to ask for a quote. He stopped by and was able to diagnose the problem quickly and gave us a fair quote. We were able to schedule a technician for the next day. Igor arrived promptly and was very pleasant. He got to work right away, fixed the problem, and made sure everything was working before he left. I would definitely use them again, if we ever need anything. read more

Thank you Maksbuilder team for helping me servive the heatwave at the beginning of September. My AC stopped working on the worst possible day, and since I work from home, it was a total nightmare. I had two technicians come before who couldn't figure out the problem and tried to convince me to replace the whole unit. Thankfully, I was recommended Maksbuilder. They arrived the same day and fixed the issue quickly. I'm so relieved and happy with the service! read more

He is very professional and nice. He thoroughly inspected my place and gave recommendation. Excellent service and value!

Maksbuilder was exceptional, he came out on short notice when I contacted him on my air conditioner problem. He was prompt, courteous, and honest. After checking my unit out, instead of trying to make a repair he told me buy a new unit even though he didn't sell that type of system. Everyone else I contacted wanted to charge me just to come out. In today's world customer service and honestly is nonexistent. Maksbuilder is the best!!! read more

My A/C started blowing warm air so I started looking around for an honest HVAC company. Maksym responded promptly and even came out the next day to look at my unit. He accommodated my schedule and even worked quietly so as to not wake my kids. He gave me a reasonable quote and was able to fix the problem right away. More than that he fixed some things on my unit that might cause problems in the future. Really a great guy and a quality technician! read more

Slava from Maksbuilder installed a Lennox furnace in my Lake Forest home. Slava was punctual and professional, explaining every step of the installation process. The new furnace works beautifully, and I can already feel the difference in my home's comfort. Slava also helped me apply for rebates, which made the installation more affordable. I'm thrilled with the new system and the excellent service provided. read more
