My AC went out late Sunday afternoon. Contacted ACKing and set up an appointment for that Tuesday morning. Blown blower motor was replaced within an hour or so of their arrival and cold air was flowing again. Fred was very professional as was the apprentice accompanying him. Would use again and recommend AC King if you need fast and professional service. read more

We just bought a new house with 35-year-old HVAC systems that needed a complete replacement -- ducts, units, relocation, everything. As anyone who's gone through this knows, the HVAC industry can feel like a black hole of information where it's hard to know who to trust. Freddy (the owner of AC King) was highly recommended, and that referral ended up being a game-changer. Within minutes of talking to Freddy, it was clear he had the patience to educate us. He took the time to explain the systems, the differences, and his honest opinion like a true advisor. That conversation alone earned our trust. From that point on, Freddy's responsiveness, expertise, and customer-first approach stood out at every step. This was a big project -- we installed a 4-ton Carrier Infinity heat pump and air handler, redid all of our ducting, and even had asbestos abatement completed beforehand. Freddy guided us through each stage, setting clear expectations and putting us completely at ease. (The abatement team he brought in was also excellent -- clean, professional, and efficient.) On installation day, his crew showed up bright and early and got right to work. They operated like a true team -- focused, coordinated, and clearly proud of their craft. With Freddy's hands-on leadership and attention to detail, they finished this massive job by around 2 p.m. -- we had expected it to take two full days! That saved us valuable time as we were trying to move in on a tight schedule. After getting multiple estimates, we can confidently say AC King offered a great mix of expertise, communication, and fair pricing. Freddy genuinely looks out for your best interests and treats your home as if it were his own. If you're looking for an HVAC company that combines honesty, skill, and true customer care, AC King and Freddy's crew are the real deal. We couldn't recommend them more highly. read more

AC Kings, These guys are Awesome. They were here when they said they would be here. Fixed my air conditioner. Very Happy with the Service.

The AC condensate drain to my house has been heavily leaking. My husband and I thought it might have been a clogged drain. So we hired AC King for a tuneup and inspection. Reynen and Kendrick were the HVAC technicians that came to my house. I'm very particular about having people in my house. I've had contractors come, who I just do not feel comfortable with. They were very nice and polite. The checked out and assessed everything. They replaced the filter and the AC is blowing ice cold. They provided us a quote for when we eventually have to replace our AC unit which we plan on doing next year. I don't think we can find a better deal. I was very happy with the work, and how they listened to our concerns. It felt like we had very respectable friends over when they were here. We will definitely be using AC King for the foreseeable future. Thank you guys so much! read more

I needed to replace our HVAC system. After calling several highly Yelp rated companies I called AC KING for an estimate for a Bryant system. What I liked about Freddy is how quickly he responded and how friendly and informative he was. His quote was competitive without any pressure and after accepting he and his crew were out within three days. They arrived at 7am and all went smoothly with no problems or obstacles. They worked as a team and cleaned up by 2:30pm. I highly recommend AC King for any heating or ac issues read more

AC unit repaired in no time. Same day scheduled service! Professional, courteous and on time! Excellent service, highly recommended.

I started having water leaks from the AC furnace in the attic and found AC King on Yelp, and I'm glad I did. The owner Freddy was able to set up an appointment promptly and explained to me what to expect. Omar was the tech who came, and he did a great job getting the clogged drain pipes cleaned up and double checked everything else to make sure the job was done completely. He was professional and friendly with patience and answered every question I had. Plus, cost was more than reasonable for the service rendered. I may sign up for their regular service plan going forward and I believe regular HVAC maintenance service is important (I'm guilty of that and that's the reason their service was needed to begin with), and I feel I can trust AC King to get the job done right. I highly recommend AC King for your HVAC maintenance and repair needs. Thank you, Freddy & Omar. I appreciate it! read more

Very helpful and responded in a timely fashion. I would use him again. The price was reasonable.

I am very impressed with the service that Freddy and his group provided . He is a very friendly individual and was also punctual today . He came out to give us a quote and him as his team conducted a thorough inspection . He was able to beat another quote and also amazingly install a new wall heater the same day. I recommend reaching out . I also want to add that he gave us a free quote which we appreciate because not a lot of companies offer that and we had paid for other quotes before. read more

They responded the same day and scheduled and the tech for the next day. The tech was on time, did a thorough assessment to target the specific issue, and fixed the fairly inexpensive issue without attempting to upcharge me on other services and products as other HVAC companies have done. The tech included before and after pictures of the work as part of the invoice. They were quick and efficient. I highly recommend AC King. read more

Ac was only blowing out air not cooling house. Sent message via yelp replied instantly and a tech was out to my home in less than an hour. I appreciate it especially with this heat. Will definitely recommend! read more

Freddy was responsive, punctual, true to his estimate and best of all the mini-split looks great and works. Freddy was the first one to respond to me when I did the Yelp quotes for a mini-split installation and he was the quickest to come give an estimate. He also helped me find an electrician for the electrical line. I never had done a project like this before and I did things out of order but Freddy helped me to the finish line and I am truly appreciative. He could have easily overcharged me but he didn't. All-in-all... Highly recommend Freddy, you'll get quality service and someone willing to talk you through the process and assist with anything. read more

I bought my house in July 2021. Since my purchase there have been many HVAC issues that I've needed help with. This last one was the replacement of the entire heating and air unit along with the blower. Our home is 27 years old and still had the original units so we knew they were going out at some point. Fast forward to our first cold day and when we turned the heater on, we found out the heating unit went out. I texted Freddy and he was here the next morning with a diagnosis and plan. 2 days later the entire system was replaced and we're happy campers again! Highly recommend them! Thanks guys! read more

The company I work for used AC King after we tried our usual repair guy and they couldn't make it out for a week. With 110+ degree weather we needed help and fast. Lexie responded almost immediately to our request and even had an opening the same afternoon. Freddy came out and was quick to diagnose the issue, locate a replacement part and do the repair. All before 5pm on a Friday! Thank you AC King. We will absolutely call you in the future and recommend you to anyone needing AC work done. read more

FRED IS AMAZING!! we are having issues with our AC, I called Fred at noon and he was at my home with in hours with an Estimate. And let me tell you I went to ALL PRO for service on my AC. They quoted me over 25,000 on a new system for small house. Fred OMG almost cut that in half. I haven't even gotten my new AC yet but looking at all the wonderful reviews I am very confident that Fred is our Guy. I am so looking forward to working with him. May God Bless Fred and his company. read more

Worked on my unit, made sure that all my levels were up to par. Checked for leaks and anything that needed adjustments. Very good and reasonable pricing. I'll definitely be doing business with him in the future. Thanks AC King read more

I have personally used Freddy on three different properties and our commercial building. He is without a doubt one of the most knowledgeable HVAC techs I have ever worked with. I definitely recommend using them for service and parts replacement. Where others have told us we need a full condenser replacement, he was able to figure out it was just minor parts we needed. He understands electrical and refrigeration which includes all the details of why things work. Truly a mechanically minded HVAC tech. read more

Excellent and prompt service. My AC was out on one of those 100 degree days and they were out within an hour after finding them on Yelp. Thank you!! read more

We called AC King to schedule an AC unit tune-up and diagnostic to fix any cooling issues we were having. They gave us an appointment the next day. Freddie was right on time and went to work on checking over every component of the system. He realized it was a lack of freon in our old unit. He added then Freon and minutes later we began to feel the difference in the temperature in the house. He didn't try to sell us on any thing alse. I would easily recomemd freddie and AC king foe and HVAC needs. read more

Thank you Freddy for helping us on short notice. He fixed my AC and helped me set up my Nest on my phone.

I reached out to AC King on Yelp for a quick quote and got connected with the owner, Freddy. Freddy is extremely honest and trustworthy and I genuinely appreciate that about him. I have needed someone to take a look at one of our AC vents since it has always had weaker air flow causing our guest room to remain warmer than the rest of our home. I got an immediate response and we scheduled a date/time for him to stop by for a consultation. He went up to our attic to inspect our duct work and was transparent about how certain repairs were not necessary. Even though he did notice that our guest room is a bit warmer, he said he didn't believe it was advisable to spend X amount of money for repairs and to install dampers to help divert our air flow since the temperature in our guest room is not unbearable. I am very thankful for Freddy's help and honest, professional opinion. I highly recommend him to others. I know that in the future when/if I do need any HVAC work done I will reach out to Freddy 100%! Thank you so much, Freddy! read more

Fast response after hours. Quick schedule of service. Identified and fixed AC issue in less than 30 minutes and no up charge. Freddy and Greg were extremely professional and just pleasant people. Will definitely add them to my go to list of service providers. read more

When I called right away I got great customer service after the call within 15 mins Fred arrived to check out the ac unit he knows what he's talking about and he is so friendly and helpful this was the best customer service experience! Thank you Fred! read more

AC King was very responsive and fast with maintenance on a very old unit and eventual replacement. He did not push for the most expensive unit and simply explained the options, prices, and what differences there were. When his supplier didn't have the unit I ordered, he fought with them to provide a more expensive unit at the cost for the one I ordered. read more

Very professional very likable great work came in and did it. I will call them again if I have problems.

I got in contact with other HVAC companies, he was very prompt at answering calls. Family owned and Fontana local. Very helpful and polite, had no problem with explaining the issues concerning my Heater. Price for parts and work is fair. read more

Our AC system started to have problems during the hottest week of the year...We called Freddy in the evening when we encountered the problem and he came out the next morning. Freddy was quick to come out and inspect our equipment, diagnose the problem, and provide a reasonable quote for the work. The following day there was a team to replace the AC condenser unit outside and the coils in the attic. They came out first thing in morning and completed the job in about 6 hours. Everything was installed and verified professionally. The team also laid out floor covering inside the house and took their time cleaning up afterwards. I highly recommend AC King! read more

Freddy responded super quick to my message, listened to my issues and my youtube education about A/C, was right on time and got my a/c going again. So impressed with his transparency about what he was doing that I will have AC King back to quote updating my antiquated A/C system. Nice to work with an owner/operator. read more

Our AC stopped working in the middle of august, which was awful. I reached out on Yelp at 0100 and got a response from Freddy early in am. He was able to call me and get me scheduled same day within a couple of hours. He informed me prior to his arrival and was prompt on his arrival. Very professional. Explained to me the issue and gave me a quote right away. Had the AC up and running instantly and without breaking my bank account. Amazing work and was very satisfied customer! HIGHLY RECOMMEND! read more

Quick & professional. I called on a Thursday at 3:55pm expecting to not be able to get anyone out for a few weeks (it's been hot, so I'm sure he's been busy). Freddy answered right away and was able to be out to my house within 20 minutes (I'm in the same city). Came out, diagnosed the problem, and came back early the next morning (we had to wait for the pipes to unfreeze) and fixed everything. Air is now blowing full and cold . Would def. recommend. Thank you Freddy!!! read more
