They performed an inspection, found the problem, and fixed it right away. What I really appreciated was that they also checked the ventilation system and honestly told me that it was clean and didn't need to be serviced. My original request was about the heating not working, but they actually did a bit more by checking everything and even replacing the filters. It was refreshing to see that they didn't try to upsell unnecessary services, which I truly appreciated. I will definitely be using their services again in the future.

He quickly diagnosed and fixed two heaters that others had failed to repair, after wasting both my time and theirs. What had become an ongoing frustration was resolved in under an hour, and he handled it all effortlessly and with a smile. Vardan truly knows what he's doing. Professional, efficient, and a genuinely great guy. Great value too. Highly recommend HVAC Control.

5 Stars - Sean at Fusion Star Sets the Gold Standard for Professionalism…read more I recently got multiple bids for a full central HVAC replacement and complete duct redesign on my home in the valley. While I held off on my project for now, I have to give Sean at Fusion Star an enthusiastic and well-deserved 5-star review. Sean delivered the most comprehensive, professional, and detailed proposal among all -- a full 15-page document that spelled out every single detail with exact equipment models, clear scope of work, diagrams, attic prep requirements, and thoughtful exclusions. In a field where many contractors cut corners, give vague estimates, or try to low-ball with minimal information, Fusion Star's proposal stood head and shoulders above everyone else in quality, transparency, and legitimacy. Even after I let Sean know I was pausing my project, he continued offering thoughtful advice on what to double-check and which key items I should make sure were included if I went with anyone else in the future -- all with zero benefit to him. That level of genuine care and integrity is rare and extremely commendable. If you're looking for a legitimate, high-quality HVAC contractor who truly puts the customer and craftsmanship first, I highly recommend Sean at Fusion Star. They earned my business in every way and I won't hesitate to call them first when resuming my project or any related future work. Thank you, Sean -- you run a class-act operation.

In the middle of a California heat wave, I was frantically searching for someone to repair our AC…read moreunit. In the past, I had always used Conejo Heating and Plumbing, but unfortunately I had a really dishonest experience with their plumber last week and no longer felt comfortable supporting that company. So I turned to Yelp and found this company. I reached out and received a very quick response from Sean. He was able to come out just a few hours later, successfully diagnose the problem, and replace a part for a very reasonable price. He was honest and transparent, and I really appreciated that he tried a few different solutions before getting the unit up and running. I'm happy to say I've found a new go-to AC company. It's a smaller business, which I always like to support whenever possible. Highly recommend!

Called on Sunday 4/19. Call was answered by the company's answering service. She took down all my…read moreinformation and told me Keith would be giving me a call to discuss my situation and schedule service. Keith never called. I waited until around noon on Monday to call back and spoke to the same woman who answered my previous call. She remembered my call after hearing my first name and double checked that all the information she recorded the day before was correct. It was. She apologized and stated the Keith would give me a call. I have still not received a call back to schedule service. My A/C stopped blowing cold and my unit is 14 years old. I guess if KeithHAC is too busy to schedule service on a system that likely needs or will need to be replaced soon for thousands of dollars, I will find a different HVAC company that is better with customer service, communication, and wants to add new clientele to their business. AVOID KEITH HEATING AND AIR CONDITIONING!

I wouldn't hesitate to call them again for any heating or AC service in the future.

Friendly & Relatable Company!…read more I called three companies about my AC, and Unity was the only one that actually got it right. The first two either gave me the wrong diagnosis or tried to push parts I didn't need, which ended up wasting my time and money. Unity's team came in, figured out the real problem right away, explained it in plain terms, and fixed it quickly. The tech was friendly, professional, and honest--no upselling, no nonsense. After all the runaround, I'm so glad I found a company I can trust. Highly recommend Unity!

Have you ever found yourself calling around, comparing prices, and scrolling through Yelp reviews…read moretrying to find the best deal and service? Look no further because Shay with United Construction is the only call you need to make. He's responsive, punctual, fairly priced, and the quality of his work is outstanding.

Within 30 minutes, Shay had it fixed by installing a new capacitor and even recommended a hard-start kit to keep my unit in great shape. If you find yourself in the same predicament, call Shay. He'll pick up on the first ring and take excellent care of you. Thanks again, Shay, I look forward to working with you and your company in the future!

Working with Brandon on getting several estimates for different options was extremely smooth. He was friendly and responsive as I asked for either clarifications or new wrinkles to the plan and a pleasure to work with from start to end. The estimates were all very competitive, even generous considering the amount, quality, and extra detail of the work. On that note, the installers, Richard and Sergio, were true rockstars and deserve special mention for their meticulous attention to detail and all the little extra touches! Our attic looks MUCH nicer than how they first found it. Due to unforeseen circumstances, they had to quickly pivot and somewhat change the plan on the first day of install and you'd never know it from how smoothly they operated. Shout out to Susan on the admin side to boot! The system runs great and is a huge upgrade from what we had before. Bring on the summertime!

Also added a new water heater and, my favorite addition will be the split installed in a back room add on with a cathedral ceiling that's difficult to heat/cool on its own. Each installation came with its own specialist, and each team was amazing. They took such good care in ensuring the carpets were covered, and their cleanup was fantastic - including one of the guys who walked the driveway and area in front for nails that may have been dropped!! Anyway, I'm happy to recommend these guys to anyone needing similar work. Oh and btw their financing program is good too with zero % interest making it good value for me.
