AC Cool has been my best and favorite company for home service for 15-20 years! Owner, Paul, installed my first furnace and air conditioner, maintained them and now replaced. A difficult installation in an attic was completed in a morning by competent and considerate workers. From Claudette Shaw.

AC Cool replaced my entire HVAC system last January. I received quotes from multiple companies, and AC Cool gave me multiple options and pricing based on my specific needs (sq ft, # of floors/bedrooms, etc). They were by far the best option and value. As an educator, they valued my budget, time and schedule and were great to work with for a full HVAC replacement.

We had a very antiquated HVAC system in the new home we recently bought. We knew we had to replace it, and we had wanted to move the system up into our attic. Another company that we interviewed said they could do it. However, when Paul from AC Cool came and took a good look at our attic and where all of our vents were, he told us that it would not be a smart decision to put our HVAC in the attic and he gave us solid, factual reasons why not.

Paul took the time to explain everything to us and we appreciated his knowledge and his looking out for what would work best for our home, rather than what would put more money into his pockets.

Paul and his team were very professional and friendly and clean with their work. We felt extremely lucky to have found AC Cool and to have had them do our HVAC system remodel. Paul suggested options to us that made our system more updated and quiet and he was able to move our condenser from where it was easily seen from our living room window to the side of our house where it is no longer visible.

Paul, Kate and other installers made our HVAC replacement effortless and we would highly recommend AC Cool to anyone needing their HVAC updated or replaced!

We just had our fourth AC unit installed by AC Cool. They are amazing! They are our official go to company ANYTHING AC/Furnace related.

This has been the best customer service I experienced in the last 5 years! Being older and a widow, I have been overcharged and paid for unneeded repairs many times from the big companies. The minute I spoke to Kate I knew I called the right AC company. She if direct, honest and very detailed. This family owned business has earned my respect. Bill Crews showed up on time, has excellent communication skills and never tried to sell me anything. He went up 2 stories in the heat and never complained once. I didn't have to replace anything, my AC is working properly, I just have Old windows and doors that don't hold in the air tightly so it has to work harder. He was honest and explained how the system works. Highly suggest you call them first before anyone else! Hats off the owner for having such an amazing crew.

Doreen R., Orange, CA Via Yelp Testimonial

Super quick response to my initial call. Specially when we were having the heatwave and no one wanted to work on the heat. They came replace a motherboard on my inside units and diagnose the outside conditioner. They advise several options which led us to make a decision to replace because the age of the air conditioner. The company owner worked with my husband and we got an amazing deal. Highly recommend this company.

We got a full new HVAC system from AC Cool 3yrs ago. Paul was great to work with and did a nice job. It's been a worry free 3yrs....until our system stopped pushing cool air yesterday afternoon on Labor Day weekend!!!

It was the hottest day of the year in a record breaking heatwave. It was 87 indoors. Needless to say it was a miserable sleepless night for my entire family. We called Paul in the morning and despite his full

schedule, he promised to try and squeeze us in the same day. Paul was at my house by early afternoon and brought the part along with to fix the issue. His calculated guess and experience was spot on!! He replaced the part that was under warranty and had the AC up and running in less than 10 minutes. I'm so grateful and relieved. System has been running for the past few hours now. Seems to be working fine and inside temps are dropping again. God willing we'll have a cool, comfortable and restful night of sleep.

My AC evaporator unit was leaking so I contacted 4 companies on Yelp for help. This was on a Sunday when everyone was closed, but Paul with AC Cool was the first to contact me and actually schedule an appointment for the next day. His technician Carlos showed up on time (even a little early which was awesome) and quickly diagnosed the problem (clogged pvc drain lines). I cannot say enough good things about Carlos. He was on time, courteous, explained everything that needed to be done, cleaned up after himself, and best of all, fixed the problem. We are now enjoying a cool house once again and the family is happy. Oh yeah, forgot to mention that the cost to fix was very reasonable! I'll be calling them back and asking for Carlos if anything else goes wrong with my AC in the future.

Chris F., Tustin, CA Via Yelp Testimonial

Our heater wasn't working properly and Jeff came out and quickly diagnosed it as the Nest thermostat not set up correctly. He was in and out in 20 minutes, extremely helpful and friendly. We will be using AC Cool for any of our future HVAC needs!

They came out to tune up my HVAC system heater and AC and the technician was knowledgeable and friendly and spent over an hour giving us a great yearly tune up! I will have them back again no question!

Jeff came by on very short notice and assessed the problem within seconds. He was able to fix it in under 30 minutes.

Thanks to Paul, Jeff, and Kate for saving us from melting in our office!

Toni Rodriguez Via Google Review

Our AC condenser suddenly went out on a Friday, of course during a hot stretch of days. I called a few places that couldn't come out for several days, but a highly rated company was able to come out that evening. After a long assessment they told me I needed to replace everything as there were several problems, and it would be $8000 (this is a 7 year old unit). After a good cry and a chat with my father-in-law, I called AC Cool at his recommendation. They were able to come out Monday, and upon inspection rats ran out of the unit. They had chewed up the wiring. We were also a little low on refrigerant. They did the repairs right away. Total cost: under 500!!

I will use and recommend AC Cool forever to everyone! Thank you for being honest and not taking advantage of people.

Sarah T., Yorba Linda, CA Via Yelp Testimonial

This is a few months overdue, but I did still want to write a review. A/C Cool is top rate in all respects. The office manager, Katie is SO nice and extremely competent! My family has used A/C Cool for maintenance service for many years and we are all very satisfied.

In November, I purchased a new home. It needed a new HVAC system and once again, A/C Cool provided the service and again all is well. I would recommend A/C Cool for ANY HVAC service. Thank you all for wonderful service and for a job well down on the new house!

Many thanks,

Kathy W., Irvine, CA Via Yelp Testimonial

We are very happy with our new system, we couldn't have picked a more reliable and knowledgeable company. When our old system started to fail a friend recommended ACcool. During the time we were dealing with our old system staff were very patient and helpful, before coming out for a repair they'd give us different advice over the phone, walked us through different steps in hopes we could fix the problem and save us money. They kept our old unit running for much longer than we expected thanks to their expertise. When we made the decision to invest in a new unit, Paul gave us different options and good advice based on our family's needs. We have been extremely happy and comfortable with our new unit and with the whole process. All technicians were always very clean, helpful and respectful, they had everything installed and running without hiccups, everything went really smooth. ACcool is the only company we will use for our hvac needs from now on.

AC Cool recently replaced my entire AC/Heating system including the ductwork and the job went perfectly. Their pricing is fair. I obtained five proposals overall and AC Cool provided the best equipment and installation for the price. Their workers were great to work with and cleaned up everyday without fail. I replaced a system that was more than 25 years old so this upgrade was way overdue. I now have a clean energy efficient system with more cooling that I could have hoped for. Thanks AC Cool.

Beyond Impressed With Their Service

The most professional crew I have experienced in a long time. Kate listened to my cry for cool air and was so helpful in every step of the process. Paul took his time to figure out the best solutions for our replacement of new HVAC system. The crew was on time, clean, courteous, professional, and they all worked very well as a team.

We are beyond impressed with their service and will recommend them to anyone I know that needs repair or replacement. All around a Great Job!!

Very Honest Company

Jeff Allen fixed the innside blower in just a few minutes. A blowen capacitor. A very honest company and if you want to reward this kind of honesty call AC Cool.

Another company told me I needed a new system, $20,000

A Company We Can Count On

Wow! I highly recommend AC Cool. I called and within 24 hours I had a technician at my house. He arrived on time! He took extra time to explain each step and the process. The quote was very reasonable for the work and was fully explained.

AC Cool is obviously highly motivated toward providing first class service.

I feel very thankful for the peace of mind that for any future issues, we now have a company we can count on. So wonderful to have found a honest, fair, knowledgeable and experience company. Thank you AC Cool team!

My New HVAC System Is So Much Better!

AC Cool is one of the most professional companies I have worked with. From setting up an appointment for a quote to replacing my HVAC and Furnace, to completing the job, I was met with nothin but the utmost professionalism. Their price was fair, the crew showed up on time, worked dilligently, was professional and cleaned up after they were done. My new HVAC system is so much better! It makes my old system seem like just a regular fan in comparison. I would highly recommend going with AC Cool.

They Get It Done Right the FIRST Time

This company is simply that honest and amazing. I want to take a little time out to thank Kate for taking my call 3 weeks ago, even though I did not fully need their service yet... she was very patient in listening to my neighbor's AC problem (making loud whistling noise) and was able to speak with their technician and call me back with some recommended solutions. I felt a lot of folks would have rushed you off the call the minute you start to ask more than 3 questions. Luckily they owned the responsibility and got that replaced, or else I would have paid half to get that fixed for them.

Till this day I appreciate the installation they did for us (3 yrs ago) and was super honest with their pricing and showed up on time getting the job done right and fast. This is what you call a true professional AC company when they get it done right the FIRST time and not have to start their sentence with "BUT, AHm, maybe or sorta... blah blah excuses".

Keep up the honest work (not a lot around anymore) and I always mention your name to the neighbors if they need some sort of AC service... trust me!

Jeff W., La Palma, CA Via Yelp Testimonial

Highly Recommend AC Cool

Long overdue review. I had been told by [another company] that I needed a new heating unit. AC Cool checked my unit, replaced a defective part, and I was on my way, with heat and comfort. Service was prompt, price was fair, and they were honest!!! I highly recommend AC Cool and will use the every time the need arises.

I’ll Be Trusting Them With My Future HVAC Needs

They performed routine service on my furnace several months ago and did a great job. The tech wore a mask, was very respectful of the property, and seemed very knowledgeable and trustworthy. I'll be trusting them with my future HVAC needs.

Very Honest, Very Thorough

I contacted AC Cool after reading reviews on Yelp, the customer service over the phone was excellent. The technician was on time, they only charged me an hour but probably did 1.5 hours of work. Very honest, very thorough and nice. I believe my technician was Bill.

Regardless... I highly recommend them. I referred a buddy of mine to them and he had similar feedback as well.

Great Repair Skills!

AC cool company is a reliable company. Bill crew at AC cool came to my client home and repaired the AC . He repaired leaking inside of the condensing unit. Also repaired the leak and pressured the system.

He is honest and great repair skills! He also did all other extra repairs . My client and I was pleased with his work.

Able to Quickly Troubleshoot My Heater Issue

Bill from AC Cool was really a nice guy, sounds pretty honest, and able to quickly troubleshoot my heater issue. Before calling AC Cool, I had another heater technician that came, took a look at my heater, made his diagnosis, and told me that it would've cost about $1600 to replace the system. I couldn't believe it. I don't use the heater much and felt like I was being scam for $1600. AC Cool took care of my heater and I didn't have to spend $1600 to replace a system. Also, I found Kate, the business owner, to be patient and helpful. I think in the future if I have issue with my heater or AC, I will contact AC Cool again.

I recently had AC Cool install an air conditioning unit in our home. It couldn't have been easier. They were terrific and thorough, and we couldn't be happier. They're an easy recommendation for anyone needing HVAC service.

Glad to Trust Them… To Keep My Equipment Operating Well

Bill was here and I was so glad I made the appointment with AC Cool first. I had 2 other appointments lined up, but was happily able to cancel them. My H/VAC is from Carrier. The company that installed it did not provide good customer service.

Bill adjusted the vent slats to the rooms so that the rooms would have broader air coverage. He also showed me how to operate the thermostat, which I was operating, but not really understanding how to set it. All in all, I was very satisfied with this company and will be glad to trust them to come on a regular schedule to keep my equipment operating well. : )

Did an Outstanding Job

Could not be happier. Thought I needed a new heater and AC as both units were very old. They fixed the AC by replacing the fuse and it's working great. The heater was close to 30 years old and did need to be replaced. These folks provided the most competitive quote we received. Arrived on time and did an outstanding job. Left the work area cleaner than when they arrived. Pleasure to work with.

AC Cool does it again!

Our AC was working intermittently over the weekend heat wave so I called them Saturday afternoon. They picked up the phone right away and we scheduled servicing for Monday between 10:30 and 11am. I was happy they gave us a 30 minute window and our technician, Bill, showed up right on time.

The fix went smoothly and was very reasonably priced.

I will definitely keep using AC Cool as my go to AC repair company!

I just got off the phone with Sally who was incredibly helpful and attentive. She spoke to the boss who went ahead and okayed the repair and I am more than pleased.


Answered Our Call With a Smile

Katie answered our call with a smile (you could tell) and was able to help us out during this heat wave. She said they were running a special emergency on call service and they could get us in! Paul arrived the next day was quick and got the job done! Paul was very informative and helpful. We would definitely use AC Cool again.. (hopefully we do t need them anytime soon , though). But if we did they would be the first company we call!

Thank you so much to AC cool! Our home is now "cool"

If I Could Give…10 Stars, I Would!

If I could give these guys 10 stars, I would! The owner and the staff and top notch in service and ability. During a heat wave, AC Cool didn't have a tech available on the same day, so I mistakenly tried another company. The other guy wanted to charge over $1,000 for a new blower, but I had AC Cool come anyway, just to get a 2nd opinion.

Thank goodness we did! AC Cool found a painters bootie/shoe cover that had been sucked up into the blower causing vibration and reduced airflow. The foreign object was removed and the unit is just fine. The vexing bootie was removed in just a few minutes and I saved a ton of money! I'm so grateful that AC Cool is honest and and trustworthy. They certainly have earned our business! Thank you Katie and the AC Cool team.

It Is Difficult To Find a Company That Cares This Much About Service

A C Cool installed our air conditioning/heating system over 4 years ago. They also have been doing maintenance checks on a regular basis. We have had some unusually hot weather recently and that is expected to continue for some time. Saturday evening our AC system failed, we left a message for A C Cool, they returned our call and scheduled an appointment for the next morning (Sunday). We had visions of having to wait for days/weeks to get service under the hot weather conditions. Paul, the owner, said because we were current customers and our system was down they wanted to take care of us immediately and they did. The complete service call was covered by warranty (parts & Labor), awesome! It is difficult to find a company that cares this much about service to their customers and shows it in their actions. We, of course, recommend A C Cool.

Honest Work and Helpful Service

AC Cool sent Paul out to help us today as we lost AC last night. He quickly found out it was a faulty trip switch by AquaGuard. He was able to rig our system safety to work over this weekend and he's coming back on Monday. Wonderful genuine guy we really appreciate the honest work and helpful service. He also fixed our bypass damper that was installed incorrectly by the builder. And he also checked all the levels on the condenser outside.

A Top Notch Company

Two years ago I posted a positive review for this company and after another round of great timely service here I am again. Hard to find a good mechanic, plumber, electrician, or a/c company. When you do, you have to give them props for running a business in a professional and honest manner. Most that I have encountered are in it for the short term quick buck. A/C Cool is a top notch company and a must go to for those in need of quality service at a fair price.

The best recommendation a person can give is to say that they would definitely use them again. That's where I am at now! They were quick adn thorough.

Saved Me $1,000s of Dollars

AC Cool gets 6 Stars but Yelp limits me to 5 and I am certain they have plenty of qualified installers but one stands out for me - Rob Timberman. He came on site and assessed my existing HVAC system from the existing equipment installed to the ducting in the garage and attic. He asked me what issues we had and I told him the biggest issue was our Master Bedroom was darn COLD in the winter and darn HOT in late summer.

The master is the furthest room from the furnace and on the east side of our house (no sun in late PM) and on the second story. Rob suggested a very efficient 17 seer, 4 ton, Carrier solution with his air flow balancing strategy and it worked. The two other HVAC contractors proposed higher capacity solutions and relocation from my existing garage location to my attic. Rob literally saved me $1,000's of dollars and I have a great result.

The owner Paul came onsite for our installation and personally installed the new Ecobee smart thermostat with Alexa integration and mobile phone app to control the system remotely if needed. Paul was very conscientious about informing me of the Carrier, SQAMD and So Cal Gas rebates and how to apply which netted me a credit over $1,000.

Do yourself a favor and ask AC Cool out for an onsite visit to assess your heating and AC needs.
