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

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

Ihor installed our new air conditioning unit, and everything went smoothly from start to finish. His work was neat and well done, and you can tell he really knows what he's doing. He's also very friendly and pleasant to deal with, which made the whole process easy. The price he offered was excellent and more affordable than others we checked. We're very satisfied and would definitely recommend him. read more

Absolutely incredible work. Thorough and honest. The price was the only honest and fair price I got, given I knew the scope of work and how much effort it was going to be. They arrived on time, worked hard and fast and left no mess. 10/10 would use them again. In fact, I will be calling them for a summer HVAC maintenance soon! read more

Truly one of the most professional home repair people I've had the joy to hire. Maksym and his team were awesome! After helping our 22 year old system squeeze 6 more month of cooling out, we finally needed a new system. Maksym charged a very fair price (I had quotes from places like the Costco HAVAC people and a few others that were crazy high prices and full upselling). I was shown a variety of options by Maksym and wasn't sold on anything but rather just given the differences and I made the choice that best fit our need. Maksym came back a few days after the new system was installed to double check the new system after being used for a few days to assure it was all working as promised. While we won't need any help in this area soon, we would 100% recommend you consider using Maksbuilder! I'm confident you will feel as satisfied as we feel! read more

See all

My A/C would not turn on suddenly so I went on Yelp and requested repair ASAP after 5pm. Maksbuilder was the only business who was willing to come same day. Igor showed up about an hour later and replaced the faulty capacitor flawlessly. Very friendly. Highly recommend. read more

We had an AC emergency in the weekend Igor was able to come out and begin diagnosing our issues, after some investigating he came to us with several solutions for short term and long term fixes. We went with a choice we felt comfortable with and the repair cost was actually lower than originally thought to be. Back to sitting In a nice chilly house during the summer. Thanks Igor! read more

Highly recommend Maksbuilder for HVAC installation. Maksym came out to estimate quickly and in his follow-ups identified issues with other contractor's specifications, such as mismatched air handler pairing. This attention to detail is what gave me confidence to go with him. He was kind enough to work around my schedule to get installation done quickly. read more

Maks is terrific - he is one of the rare people you find who is excellent at what he does, reasonable and fair in his business practice and just a really good human being. I wish I could find service people like him for everything we need (plumbing, roofing, housekeeping). The reviews I read were consistent with what I found - great communication, timely response and very professional He's a gem and we're happy to give him our highest recommendation. read more

Maksym came out to handle maintenance on our AC unit, and he did a truly professional job from start to finish. He was clean, efficient, and left everything spotless. Communication was excellent--he replied quickly, gave a clear timeline, showed up exactly when promised, and stuck to fair, straightforward pricing with no surprises. As someone who values no-nonsense service, I really appreciated his direct approach, reliability, and quality work. The AC is running great now, and he explained everything clearly along the way. We'll definitely be calling Maksym again for any future HVAC needs, and I recommend him to anyone in the area looking for dependable AC maintenance or cleaning. Thanks, Maksym! read more

I have not written a review in quite some time, but found compelled to lift my lazy fingers for MaksBuilder. Highly, highly, HIGHLY recommend. Maksym and Igor accommodated my broken heater the same day, with haste, and even stayed past what I would consider normal working hours to finish the job. They charge VERY reasonable prices and I ended up paying a fraction of what was quoted by their competitors. Maksym is responsive in his communication and coordinates his team effectively. Igor is simply a smooth operator and is very professional/pleasant to interact with. I will be honest - I do not think I've been this happy with a home improvement/maintenance company before. I hope my enthusiasm convinces you to give them a try...you won't regret it. read more

Yelp is starting to become my go to resource for various projects around the house. This project was no different. The AC unit wasn't working at my property in the OC and looking around Yelp, I came across Maksbuilder. With the limited number of reviews, I was a bit skeptical. I sent out multiple requests to various companies. With Maksbuilder, Maksym replied himself. We got on a call quickly and Maksym said that he could go out and assess that same day, but likely it would be down to two items of failure. Maksym arrived during the window and found the issue as he anticipated and repaired that unit. The AC works as it should now. I'll also mention that Maksym went into the property to do some general maintenance around the ducts, which I didn't expect. A few days later, Maksym checked in to see how the unit was holding up. The service, I'm quite happy with, to the point where I've scheduled him on an annual maintenance for the unit. read more

Rinat did a fantastic job cleaning our AC unit coils. And he was so friendly and considerate coming in and out of the house. 5 stars

Finally found someone we can trust who wasn't trying to up-charge us on multiple things that wasn't even needed to get our AC working again. Easy communication, came the same evening, works fast, straight to the point. We would recommend his service to anyone! read more

The most affordable furnace installer there is by far. They do great work and you will not be disappointed.

Thanks for HONEST and fair pricing! After I was price gouged by another big HVAC company, Maksym was able to quote a decent price to price match. Would use for future needs. read more

Maksym at Maksbuilder was quick to respond to my quote and was also flexible to support a next-day visit on a Sunday morning. He was able to address the contactor issue in my AC unit. Job was completed in a timely fashion and price was reasonable. I would use his services again should more needs arise. read more

Maksym was responsive by text, thorough in inspection, meticulous with his work, and just a fantastic, trustworthy person to deal with overall. There are a lot of people you can turn to on Yelp when issues with AC arise and admittedly Maksbuilder wasn't the first on the list that I reached out to, but Maksym offered a second opinion with no obligation or expectation, came after hours, and on time. Thankfully he did, because it saved me from replacing an AC blower that didn't need to be. The best way to describe this level of service is like you're taking care of your own home. Well worth inquiring with someone whose quality and experience shows. read more

Ihor came the same day repaired the unit in less than 30 minutes. He also checked all the components to ensure the unit was running properly. Very friendly and communicative. The assessment/Diagnostic was free/no charge to address the problem. everyone else called was anywhere from $75 to $100. Just to visit. Exceptional Value/Cost: $75. On a day that is HOT $75 is very reasonable and comparative to what is in the market. Friendly, informative and service requested was performed. read more

If you need someone reliable, trustworthy, and above all, ethical, stop searching and hire Maksym. That's truly all you need to know. But if you want more: Maksym came to my rescue at the last minute when my AC failed completely. Other companies left me reeling with sky-high quotes--some exceeding $20,000 to replace the entire unit without bothering to do a detailed check. Maksym arrived promptly, provided an exceptionally thorough diagnosis, and not only fixed the problem the very same day, but did so with a warmth and professionalism that's rare in this business. Beyond his skill, Maksym is simply a pleasure to work with. He operates with an integrity and honesty that is evident the moment you speak with him. He laid out exactly what repairs might be needed down the line, giving me peace of mind and confidence in future decisions. My AC unit is old and well past its prime, but Maksym managed to breathe new life into it, saving me thousands and buying me valuable time. It's rare for me to say this--I'm notoriously skeptical and picky when it comes to hiring help--but Maksym has earned my complete trust and loyalty. When the day finally comes to replace my unit, he will be the only person I call. Maksym and Maksbuilder, thank you for your incredible work. You turned what could have been an expensive nightmare into a smooth, fair, and surprisingly pleasant experience. You've gained a customer for life. read more

We had been dreading the whole process of getting our old A/C replaced, but Maksbuilder made it an absolute breeze! read more

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.

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

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

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

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 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

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

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

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

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.
