Johnny from Iwai did an excellent job of trouble shooting both a multiple wire issues both inside and outside. He replaced the circuit board as well. We plan on using them again. Lisa did a great job of getting information out to me such as parts, warranties and follow up appointments. My next door neighbor recommended IWAI and I would as well! read more

Complete honest company Johnny was excellent. I highly recommend him. I work on honesty when I hire people for work that needs to be done.

The tech that came out was Johnny. I was having a problem with my AC not being able to cool as well in the evening, as it did in the morning. I thought it might be the AC itself. I am very happy they sent Johnny to check it out because he is super sharp, and he figured out that the AC unit was fine, and he reconfigured the controller to better match my house. He spent some time explaining what he did, to me, and I also came away with a better understanding of how my AC works. read more

I've been working with Iwai Cooling & Heating for several years now and have always had a great experience. The team is consistently prompt and keeps me informed about their arrival times, which I really appreciate. When they're working in my home, they're always courteous, professional, and respectful of the space. Craig, Lissa, and Jacob are fantastic to work with -- knowledgeable, friendly, and reliable every time. It's clear they take pride in their work and in building long-term relationships with their customers. I'll continue working with them and highly recommend Iwai Cooling & Heating to anyone looking for quality, dependable service. read more

So we just had our HVAC system serviced from Iwai Cooling & Heating. We pay a yearly service fee and they'll come out before summer and before winter. Shoutout to Lissa for reaching out to us and reminding us that it was time for the service. Anyway, Jacob showed up to work on the system. As soon as he walked through the door, he immediately put on those shoe booties on. Love that! I told him about one of the vents not producing enough air. Before he left, that vent was pushing out nice cold air! My wife had a question about the filter. Jacob answered her question AND told us about the system that we have. Very impressed! I would definitely recommend Iwai's Cooling & Heating for all your HVAC needs. Mahalo Iwai's read more

Iwai fixed my furnace's ignitor switch last year in January. No issues, good service. Heater broke again 13 months later. The exact same part broke. Warranty is 12months. Ok, got it, need a new one. Went around and around with Craig, the owner, about getting a discount. He did end up giving $35 off but my total bill was $329. This is a $30-$50 part that should last min 3 years..,most last a lot longer but life does happen. Not like it gets a lot of use here in SoCal. I wasn't asking Craig to loose money, but to cover his costs for parts and labor and not add additional margin. Pay your tech, pay the cost of the part and add a little for admin and take care of a customer. Tech was fantastic. Craig not so much. Lost customer for life read more

Service tech arrived on early and returned back on time due to office scheduling error. Courteous and professional. Was able to locate damaged, shorted HVAC control wiring in attic and repaired it along with blown fuse. Labor charge per hour seemed fair for work performed. read more

I am always impressed by Lissa, Jacob and the Iwai team. Their customer service is excellent and they are always very responsive and knowledgeable. I highly recommend them. read more

As a long time Realtor in Los Angeles, I have a roster of heating and cooling companies in my database. But Iwai cooling and heating is my preferred referral, so much so that I use them on my own properties! They're knowledgeable, experienced, dependable! And Lisa who runs the front office and scheduling couldn't be more accommodating and responsive, anytime one of my clients ask for an HVAC company, my go-to is always Iwai cooling and heating. Thanks guys! Dan Ortega Sothebys International Realty read more

Jacob is a great professional. He is courteous, knowledgeable, and cleans up after completing the job. Last year, they changed out a pump and just had a quick tune up before summer comes. The hardest thing is remembering to schedule those maintenance visits! read more

We were very pleased with our technician Jacob. Very polite, professional and thorough. He wore bottles every time he came into our house and took them off when he left. Our unit is a condo and he went up on the roof to check the unit and checked the main mechanism and the intake in the condo brought a new filter. We had recently replaced it so he left it with us. Very impressed will use them again. read more

This company has been our go to for years. They are always responsive and this last service call they honored the warranty. We have used them to complete duct work and a few years ago they replaced our old unit. Their response to our calls are quick and they are professional. read more

Cannot give higher at this time only because they have not serviced my air yet. I wil give this business my final review after they come out on July 2 to fix my air. I called them on Friday, after my past air conditioning man retired and referred me to Iwai. They had an opening on Monday afternoon but I am leaving town until Wednesday night and they had no openings until July 2. So, I will sweat it out until then because I only like to take referrals from companies I have used in the past. read more

I've used Iwai Cooling & Heatng for several years. Customer support, on-site service, experience and integrity have made them our preferred -- and only -- HVAC contractor. read more

I found them via a friend's referral, and they did not disappoint. Pricing was competitive for a full central HVAC system replacement during our remodel of our 1-story house. We didn't want to waste resources heating and cooling the whole house all the time so their solve was to separate into zones using dampers. The crew works fast and got done in a couple days. When it came time to move in, they came back to do some fine tuning with very short notice, and nights in the 40s aren't so bad anymore. Thanks guys! read more

Jacob was awesome! Professional, friendly, and helpful. I admire their honesty and transparency with their service/pricing.

I have been a customer with Iwai Heating and cooling for many years. I am a firm believer in preventative maintenance for my essential home appliances. I have contracted with Iwai to check and service my heating HVAC unit every year. I have had my HVAC unit for over 20 years and it is in excellent condition. They are very professional, knowledgeable and trustworthy. I highly recommend them. read more

I wanted to update my previous comments with another five start review from Iwai. Since they relocated my AC condenser unit five years ago they have been out a few more times for maintenance and misc repairs and things have always going smoothly. The most recent visit was yesterday and they replaced the small condenser pump that was on the verge of failing (as evidenced by the awful noises). Brandon was prepared, fast, and pleasant. Thanks for the great service...again! read more

Our AC went out this last weekend in Saturday. Sunday, I went on to Iwai's website and booked an appt online and was called Monday and they were actually able to fit us in that same day! AMAZING!!! Brandon came and totally saved us. AC is back working. Learned some valuable maintenance protocol and will definitely be setting up yearly maintenance to help keep our AC and Heating operating at optimal performance. read more

Installed my system 7 years ago, fixed my furnace over the Christmas holidays with some issues, eventually honored the warranty. I called for them to do an air conditioning checkup (everything is working just fine) and I was told they no longer come out to my area and to find someone local. read more

I called Iwai Cooling and Heatin, after getting estimates from 3 other companies. I liked Craig, the owner of Iwai C and H, because of his straightforward and honest manner. I liked what he noticed about my old system, being a good brand, but also noticed that the rotors on the air conditioner were going the wrong way, making the heat come out of the side of the unit instead of the top. I liked the plans for my new furnace, coil, air conditioner and ducts. He also suggested getting an attic fan to blow away hot air from the attic. Craig also gave me a fair, competitive price for the C and H unit. He came out to remove my old unit and install my new Lenox elite system. He was very meticulous, securing loose wires and hoses and filled a wall hole with sheet metal. The work done was immaculate, with his son Josh doing all the ductwork and installing new vents which he caulked very neatly. Every step of the way, Craig gave me different options on the installation of the furnace and air conditioner and where the tubing housing the coolant would be placed. I chose Craig's company, because I felt that in the future if I needed the unit repaired, he would take care of it. I highly recommend Iwai C and H. read more

I have been a long time customer. I have a maintenance contract for my HVAC system and the technician, Jacob, was assigned to perform the check up and maintenance . Jacob arrived as scheduled, put on shoes covers and went to work. He was thorough and completed all needed checks. In all the years of business with Iwai Heating and Cooling, I have never had a serious problem with my AC /heating system. Thank you Iwai Heating and Cooling. read more

I have been using Iwai cooling and heating for years. They maintained my old heat pump and then I trusted them to replace it. They gave the best price out of all the estimates I got. Their work is top notch and it is so good that I recommended them to everyone in my building, and my building has made them our official A/C vendor of record. read more

They are Awesome. They installers were very efficient, professional and friendly. They installed a new Central air Conditioner and changed the filter in the heater. Showed me the work they completed and took the time to reply to all my questions. I Will Definitely recommend Iwai Cooling & Heating for all your air conditioning & Heating foe services and installations. Thank you so much Richard P Colleen M read more

Great guys. Brandon is a wonderful lead. Efficient and hardworking. Would highly recommend

I would highly recommend Iwai. They were able to solve an issue with our air conditioning and avoid having to replace our whole system. They wore masks and were neat and courteous. read more

Truly excellent service. Brandon is the best! He and his crew replaced our old heater and duct work then they installed a freestanding AC unit to add central air to our house. The whole crew was great and you can tell they take pride in their work. read more

Iwai is awesome! Very trustworthy and efficient! We have used them a few times over the last 5 plus years and always get our old system up and going! Brandon is the best! Very knowledgeable and thorough! I know I can trust him and he always looks for the best solution without high costs! Very lucky to have them! read more

I have been a loyal customer since I chose Iwai to install the HVAC unit in my condo in 2011. However, due to my recent experiences with Iwai, in which I have had to endure slow service, poor communication, billing errors and insults, I will be looking elsewhere for my HVAC needs in the future. I called Iwai when my AC unit stopped working in late September 2022. My tenants had to wait 3 days without AC for them to get to me. We were not happy with the delay, but accepted it given that it was a heat wave, and they were busy. When he got there, he called me saying there was a leak and recommended refilling it and adding stop leak with a dye to show where the leak was if the stop leak didn't work. He said he would call me back with any other recommendations, but never did. After he left, the AC worked fine until the next day when it failed again. I called immediately but they did not come back until 5 days later, which I saw as an unacceptable delay, given that he knew there was a strong likelihood of the need to return. When he returned 5 days later, he made the repairs, and the unit works fine, but once again he never called me back as he had promised, and I never heard from the office about setting up an annual maintenance service plan as he had promised would happen. In addition to the service delays, and poor communication, I was subjected to billing errors that led to an unfortunate conversation with the office person in which she accused me of trying for "a freebie." The details: When I received the bill via email for the first visit, she called and requested that I mail a check, rather than pay by credit card over the phone. I immediately mailed a check and on the day of the second visit I received an email receipt for my payment. I waited for the bill for the second visit, but it never came. 3 weeks later I got 2 bills and a phone call accusing me of not paying my bills. It turned out that the office person had misapplied my payment to the larger bill for the second visit creating the appearance that I hadn't paid the first bill and only partially paid the second. When I told her I had been waiting for the bill for the second visit, she accused me - a good customer, who had always paid his bills promptly since 2011 - of trying for a "freebie." Afterward, I saw that the email she'd sent me, titled "Receipt" and showing the amount I'd paid in big bold letters, also had in small type the amount due for the 2nd visit. I had not received an Invoice like the one she'd sent me for the first visit. When I asked her what I owed, she couldn't answer, so I asked her to correct her records and send me corrected invoices and receipts. She did and I promptly paid my bill by check sent by mail which included a written complaint detailing these incidents. I have since received a receipt for my payment, but no response to my complaint. Iwai has lost my business and earned this poor rating. read more

If you are looking for affordable, reliable, and amazing service, I highly recommend Iwai cooking and heating. They provided great quality of work, flexible with my schedule and were very responsive to my needs. I will definitely go through them again for cooling and heating. My family can't thank them enough for keeping my house cool again for my family during this heat wave. read more

As I'm writing this we are in a long heatwave and of course my AC went out. Tepid, room temperature air. No one could get out because of course everyone was calling with their own break down. Somehow! Iwai made it work. Brandon arrived with an assistant and solved the issue in about half an hour. It seemed something he assessed pretty easily, had the part, put it in, and was on his way. Honestly, he was just chill, knew what he was doing, and "Easy Like Sunday Morning" on a sweltering Tuesday afternoon. Beyond grateful. Will be their devoted customer going forward. read more

I have used Iwai for all levels of AC services. From total AC installation, general repairs and preventative maintenance. 3 houses have been serviced recently and today Brandon installed a attic and garage fan. Very clean install and Brandon recommended the fans to lighten the load on my AC u No matter who has come to work at my houses I have always been satisfied with the results. The explanations of what the problem was and the solution has been clear. Thank you!! Had another great service experience! Some future things to think of as far as possible issues but was not pressured to perform till problem comes up, Prompt and quick service! 5 Star service as usual. read more

Great service and professional. Our tech Brandon came out he was on time which is a great start. He took care our our AC and had us back up and running in no time. I will definitely recommend Iwai Cooling to anyone who has AC or heating issues. read more

Iwai Cooling & Heating - New AC Unit - Heating & Air Conditioning/HVAC Near Me - Monrovia, California

Is it possible to give zero stars? We had an HVAC installed about five years ago and I'd have to say it was the very worst customer service and installation I've ever experienced. And this is from someone who had an almost 8-month kitchen renovation. We had two issues: The first was that the unit needed to be placed on the roof -- fine -- however, it leaked EVERY SINGLE TIME IT RAINED. The company claimed that they came out and "fixed" it about three times while nobody was home. We finally called another company who fixed it in one try and it hasn't leaked since. Not even during this rainy December. The second issue has not been resolved. The unit makes parts of the house vibrate. I asked about this early on and the owner said he would come and place more pads under the unit. He claimed he did this, but it didn't seem any different. The company that fixed the leak said that they couldn't put any pads under it because that had to be done BEFORE installation. This means, again, that the original installer lied. We eventually had to move our bedroom because the rattling would make it hard to fall asleep. I don't know how this guy sleeps at night. Update on 3/29/2011... I just wanted to clarify that the roof did NOT leak before the air conditioner was installed. The roof leaked AFTER it was installed. The contractor, Iwai, kept telling me that it was corrected, but it never was. Another air conditioning guy fixed it because it had to do with how Iwai sealed it. Even if I needed a roofer, like someone suggests, Iwai should have provided that service instead of lying to me. read more

The one star is for - Iwai has done good work for me before, and he respects households by taking off his shoes and I'm shallow and he's good looking but man... even if my old school parents love him, what good is a company if you can never get in touch with them? I mean, like other reviews say, you have to try for MONTHS. Yelpers - sort by low star ratings...please. You'll learn a lot. Anyway... Seriously - no one EVER returns calls. EVER. The answering machine is always on. Not good if you're trying to reach someone about service they warrantied. AVOID. read more

We had a full havoc system installed in out house by iwai one year ago. The job is subpar. Every room in our house is a different temperature with our bedroom being the hottest room. So we cannot sleep comfortably. Because the airflow is so inconsistent we tried to turn off the vents in rooms we don't use. But the vents that they installed are just terrible. They are made if chap plastic and the knob broke when I tried to shut it off. So you cannot shut off a vent or even change the direction of the air flow. Welcome to our fund house. Make sure you bring your north face jacket when we hang out in the living room and your birthday suit for our bedroom. Which sounds sexy, but I'm too sweaty and hot for any extracurricular activities. read more

We had a leak under our house from the furnace. We called home warranty and they sent someone out who said we need a new furnace and AC. I called Craig for a second opinion. He came out to assess the damage and Brandon was able to fix the problem, costing only a fraction of the estimate I had received. read more

We have a six year old AC system. A few days ago, on the first really hot day of the year, the system came on, provided cold air for about an hour and then quit. The first AC company that examined the system said we needed a new condenser/compressor. I called Iwai for a second opinion. When the Iwai rep arrived, I explained to him that the fan at the top of the condenser/compressor turns slowly and the system just kind-of whines. The Iwai rep replied, "it sounds like a capacitor." Sure enough, within 10 minutes Brandon had the capacitor replaced and we had cold air. Given their quick response, diagnosis and repair, Iwai rates five stars with us. read more

Iwai Cooling & Heating is the epitome of great service. Like many others, our A/C suddenly started blowing out warm air. We called another company first and we were quoted $9k-$12k for a full system change to fix, which I was told was our ONLY option. I then called Iwai on a Friday morning, after a friend had recommended them (they worked on his house 7 years earlier) to me. Lisa, from their office, worked diligently to get her crew to inspect my system asap. Although they were too busy to come the same day, she was able to squeeze me in the following Monday. I even received helpful text reminders about when they would arrive, and Brandon and Josh came by on time as scheduled Monday morning. They were courtesy and even brought removable booties for their shoes to not dirty our carpet. Upon 15 minutes after inspecting, Brandon stated that although my system is ancient, he felt that was the only impeding problem was a blown fuse. After replacing with a $20 new fuse, the guys ran diagnostics on the whole system, stated all else is working fine and went on their way. I was blown away by how quickly they diagnosed the problem and the honesty of their team. In summary, I would recommend Iwai Cooling & Heating to anyone. They represent the type of service that every homeowner seeks...responsive, efficient, courteous and honest. read more

Brandon, Craig, Keanu, Lissa are all awesome, excellent service, fast and efficient. Very knowledgeable and professional, I would trust them with all of my AC/heating needs. During the hottest and busiest time of the year, they came out and diagnosed my A/C unit problem quickly and fixed it on the spot. They are fast, friendly, and affordable. Learned a lot from Brandon today as he also explained what he was doing and why. Very thankful for Iwai Cooling and Heating. Keep up the great work!! read more
