HVAC reviews in Hayward, California

I just replaced a 50+ year old furnace by The Clean Sky. The new furnace is quieter, more efficient, and much better looking than I had before; there is no more exposed glass fiber, and they replaced it with dust-free bubble wrap. Very, very, very competitive pricing. In general, we had a pleasant, stress-free experience.

We had a problem with our AC, which wasn't cold enough. It was working, but the temperature wasn't comfortable. We had 3 companies try to fix it, we paid three times, and nobody could fix it. After we attempted to explain to those companies that the issue was still here, they returned and said that the air was cold enough and there was no problem. Michael, with the clean sky, was the only person who explained the basics of the AC and the only person who told me what a delta T. He also found the problem and fixed in at the first attempt.

Our system was installed in the attic, and suddenly, it was leaking; we were afraid of water damage, so we immediately shut it off. Due to the heat wave, we needed to have someone quickly. The Clean Sky was available, and we booked an appointment. They found a bad part; it was some rubber connection; they did not have the original in stock but were able to fix it temporarily so we would have the AC. 2 days later, they came back and installed the original part—very client-oriented service.

The only company that could find and fix the issue while three other companies were useless. We had a leak in our line, and all previous companies recharged the refrigerant, which lasted around 3-4 months. Michael from The Clean Sky offered a good deal on the complete repair, and we finally have a properly working system

It was some exceptional heating service! The Clean Sky was punctual and professional. They installed a new furnace the next day. They are professional and fast, and they give us the best price, much lower than we had before, which was why we accepted their services; previous quotes were outrageous, with a wait time of around 2-4 weeks. They are professionals.

My AC wasn't working, and the outdoor unit was making clicking sounds. The tech arrived fast in the evening, so I did not need to leave my office. He identified that the compressor was jammed and offered me two options: replace the whole unit or just a compressor. I asked him to check my entire system as it is over 20 years old. He checked, and it was in good condition. I agree to replace the whole unit as the warranty is extended. Excellent service, hones, as they didn't try to sell the parts that are in good condition.

Michael responded to an emergency call in the evening. Our AC stopped working yesterday and we are currently under a heat wave. This guy came with in an hour, gave us fair estimate, bought the part from Home Depot and fixed the problem within 30 minutes. Very honest work I would say. Do not hesitate to call this company. They have all five star reviews for a solid reason. Keep up the good work and thank you so much!!

The only company that takes care about the customers! Our AC was repaired by another company, and it lasted only one day. We tried to call them, and the firs time, they answered and scheduled an appointment. Nobody showed up. We were completely ghosted after that. Giving up on that company, we called The Clean Sky, and they were able to resolve our issue quickly. We never had any problem with AC afterward.

We had an estimate from a famous company and were completely silenced by the total price. I decided to have a second opinion with the clean sky and they offered a more efficient system with a lower price. We could decline this deal, and we felt nothing but gratitude for this company.
If you need a new AC, consider them.

Very pleasant experience as a commercial customer. We were replacing the rooftop AC and this company handled everything from permits and crane work to post-inspection they even noticed some minor nonrelated electric issues and recommended a licensed electrician to fix them. Very professional and well-trained staff.

In preparation for summer, we decided to service our AC. The Clean Sky was punctual, gave us a reasonable price, and was respectful and knowledgeable about their topic. They performed all the necessary maintenance and now we sure we will have a reliable AC for hot days.

Had guests over on Saturday night and suddenly our Furnace stopped working, it was a disaster and my evening was almost ruined. Even though there a lot of companies offer emergency calls when we tried to call them they either did not pick up the phone or demanded extremely high emergency call fees (charging nonrefundable $500 without any guarantees is just ridiculous). Fortunately one of the guest recommended this company. They were able to arrive within 1 hour and fix the furnace.

I was collecting the estimates for the furnace replacement, and The Clean Sky was the most transparent in the explanation and the most responsive. After the contract was signed, they completed a single day installation clean after themself, and as a bonus, installed a filter grill for free.

Our furnace was humming and did not start. We called The Clean Sky they found a problem with the capacitor and were able to replace it the same day with very nice pricing. Efficient and without any dramas and sales.

Our AC was very weak and was not able to cool down the house. The Clean Sky tech was able to find the freon leak and as our AC was pretty old we decided to replace it. This company gave us a reasonable price and installed it was, they cleaned after themself and tested it antill they very confident that everything was working as it should be. Thanks.
