I was referred to Hayes Brothers HVAC LLC by my daughter, and after comparing 7 HVAC and furnace repair companies for price, reliability, experience, professionalism, and overall value, this team clearly stood out. They handled the furnace and HVAC installation smoothly, arrived on time, explained the repair and replacement process in simple terms, and kept the cost fair and reasonable. The owner was very knowledgeable about furnace repair, heating systems, airflow, and overall HVAC performance. Nolan and the crew were polite, professional, and easy to work with. They removed the old unit, completed the installation carefully, tested everything to make sure the system was running properly, and cleaned up the work area when they were done. What impressed me most was their attention to detail, honest communication, and the quality of their work. As a small business, they delivered excellent service from start to finish. I would gladly recommend them to any family member, friend, or coworker looking for dependable furnace repair or HVAC service. Great job!

I’ve never worked with a more responsive, professional, friendly, and genuinely caring HVAC team. Every time we’ve needed heating and air service, John has responded quickly and made the whole process easy. Most recently, we had to replace our second-zone HVAC unit, and he was able to locate the equipment fast and complete the installation right away. He always goes the extra mile, explains the system clearly, and makes sure everything is running the way it should before leaving. If you’ve ever struggled to get an HVAC contractor to respond on time, schedule service, or follow through, that has not been the case here at all. Their communication is excellent, the workmanship is solid, and the service feels dependable from start to finish. What could have been a stressful HVAC replacement turned into a smooth and painless experience. John is highly skilled, easy to work with, and clearly knows his craft. He helped us feel confident about the new unit, airflow, and overall system performance. This company has absolutely earned our long-term business.

I can hardly express how pleased we are with Hayes Brothers HVAC LLC. Nolan and Robert were friendly, respectful, tidy, and very professional throughout the whole AC installation. They made the process easy, kept the work area clean, and had such a positive attitude that our whole family felt comfortable having them at our home. The new air conditioning system was installed in just two days, and everything was explained clearly from start to finish. We compared around 10 estimates before moving forward, and the pricing was very fair for the quality of the equipment and workmanship. The install looks clean, the system runs great, and our home feels much more comfortable in the warm Corona Del Mar weather. From the estimate to the final setup and testing, the overall experience felt first class. If you need AC service, a new unit, or any HVAC help, this is the team to call. We feel very lucky to have found them.

When my furnace stopped working, I first called an HVAC company thinking they were the original installer and that my warranty was through them. During the service visit, I found out a different heating and air company had actually installed the system and held the warranty. By then, I had already learned from the first technician that the problem was the pressure switch and that it needed to be replaced. After contacting the warranty provider, the repair process took three visits before the furnace issue was fully handled. There was also a lot of discussion about a maintenance plan and changes to the venting, which made the appointment feel longer than expected. The warranty covered the replacement part, and labor was billed separately. In the end, I was much more impressed with the first HVAC company because their technician quickly diagnosed the heating problem, explained the pressure switch issue clearly, and made the whole furnace service call feel simple and straightforward. What stood out most was how courteous and professional Nolan was in my home. He was respectful, careful, and even removed his shoes, which I really appreciated. The office staff was also friendly, helpful, and professional, and they went out of their way to offer extra savings. Overall, the best part of this experience was finding an HVAC team that felt honest, knowledgeable, and easy to work with. If I need furnace repair, heating service, or any HVAC help again in Corona Del Mar, they will be the first company I call.

My old furnace and AC unit were really starting to show their age, so I decided to have them replaced with a high efficiency HVAC system. Robert, the installer, has a lot of experience in the HVAC field. He gave me a call before coming over and was always punctual. His professionalism and attention to detail were impressive. The old furnace was taken out and the new one was up and running the same day, and Robert made sure we had heat before he left. He came back the next morning to install the new outdoor AC unit, tested the whole system, and walked me through how to use and maintain everything. I was so pleased with their service that I also had them upgrade my old water heater to a high efficiency tankless model. Robert handled everything, from draining and removing the old water heater to setting up the new one with all the proper plumbing, venting, and electrical work. He arrived on time and finished the job in just one day, making sure we had hot water before leaving. The whole process was smooth and stress-free thanks to their excellent communication and quality workmanship. I usually don’t write reviews, but this team really made the whole HVAC upgrade easy and hassle-free.
