Thankful a neighboring business referred me to this family run HVAC business. We have been having Cool Time service our three units for more than four years. They always come out as soon as they can when we have an issue. We also have them come out annually just to check up on our units. They're honest, knowledgeable and always very fair in their pricing. Great service business. read more

Chris and Mike did a wonderful installation on our new A/C and heating unit. Professional, clean installation and the unit works great. Pricing was good and they completed the job in two days as promised. I highly recommend them. read more

Cannot say enough about this family-based team. All of them, Robin, Mike and Chris, are all great, skillful, professional and friendly. Very reasonably priced. They got down to business immediately upon arrival, did a great job, and, one of the most admirable things about them, weren't 'salesman-y' AT ALL. Love that! Highly reliable team that is communicative and honest. Will be calling them back for regular service from now on. Highly recommended with no reservations!!! read more

I call Cool-time during the worst heatwave after my own AC company told me it would be nearly a week until they could come out .. instead of an answering machine a very nice lady answered.. ( wish I had gotten her name ) anyway, she was really helpful and even though I didn't end up hiring her company ( because of her good advice .. ) I wanted to give them 5 stars for being so helpful and having 5 star customer service .. Thank you! read more

It is an absolute pleasure dealing with this knowledgeable family owned business. They educate their customers so we can make an informed decision about upcoming changes in technology and pricing. No high pressure sales tactics with good honest opinions. Thank you read more

Amazing customer service from the moment you call in. Robin was so sweet and accommodating with my ever so changing time schedule. Was told they would be at my house the next day between 8:30-9am and received a call a half hour before they came by Robin to inform me. Mike and Chris were extremely knowledgeable and explained everything they were doing and got my AC up and running again in no time. Thank you guys!! A+++ read more

It is with a heavy heart that I am writing this review. I have use Cool Time services in the past and have been happy with them. However, this recent time they have really gouge me. They came out to fix an issue with our AC. It turned out to be a bad capacitor. They charged me over $300 to change it out and spent less than 30 minutes doing so. The part alone should cost $25 so I'll let you do the calculation. I do understand that they need to do markup and charge a reasonable rate. Yes, I should have asked for an estimate before the work is done. Then again, I have used them in the past, and they have been fair. That's why I went with them again. I'm sorry to say that I now have to look for a new AC Company. So if you do decide to use them, I suggest getting an estimate up front. In conclusion, this is the worst I have felt since talking with a used-car salesman. read more

Family run operation that provides exceptional service from the moment you call them to the time they are onsite. Mike, Chris and Robin provide a service second to none! I highly recommend them. read more

Thank you! Thank you! Thank you! Your expertise and professionalism are so much appreciated. When my parents new air conditioning system stopped working after 8 months and that company's phone and address turned out to no longer exists (yes, address wasn't legit) I was feeling panicky. You came out, diagnosed and fixed it. You restored my faith in humanity. The "other" company may not have done things right, but you did. read more

Very grateful to this family business. They fixed our HVAC very fast and provided the best service possible. Thank you for saving us and our dogs from heat this summer. Lady on the reception was very nice and called me several times with updates on their arrival. Very professional. read more

Extremely professional and honest! Our air was running constantly and slowly getting less cold. They came out quickly and fixed it. All costs were mentioned up front and more than reasonable. Thank you guys so much...especially since it is 110 degrees here today!!! read more

Have used Cool Time for a few years now and have always received fantastic service! Last time we were in a heat wave and my air went out and I thought for sure the whole unit had died. Chris came out the next day and it was only a small part that needed replacing so of course I was ecstatic. Fair pricing and always happy to support this family owned business! read more

So as it turned out, we had a large leak in our ac unit. They tried to find a nice cheap solution for us, but recommended a new compressor. We opted for the new compressor and had it installed 2 days later in about an hours time. They were friendly and most importantly, honest. Thank you Chris and Mike! read more

Mike and Chris from Cool Time are the honest type of repairmen you luck out getting. They fixed my AC quickly and reasonably priced. I had the misfortune of dealing with Novell first who tried to hustle me in complete re-build of AC with the scam of "forgetting" tools for onsite repair but could return later for $120.00 flow check. No thanks. I HIGHLY RECOMEND COOL TIME AIR CONDITIONING AND HEATING! They now have a loyal customer for life. read more

Like I predicted in my previous post...we ended up needing a big AC/heating job so we turned to Cool Time. They installed a brand new AC/heater in one of our rental properties. The old one was just too old (30+ years?) and was beyond saving. Cool Time took care of everything on time and as scheduled all while being very accommodating with my schedule AND our tenants schedule. However, in the middle of completing the job--we had a significant family emergency and they were kind enough to come out to our house (in a totally different city than the job) to finish up the payment and deliver the permit paperwork. I'm not sure if they are a family business but they definitely run like one--family values not just for them but for their customers as well. read more

Fast, friendly courteous service. I highly recommend Cool Time for your a/c needs. Mike and Chris were fantastic and patiently explained what work was needed without the pressure of a salesman's pitch. They told me they will go anywhere so don't hesitate to call them for your repair needs. Thank you Cool Time. read more

I was referred to cool time by a friend. They are a family business and treated me very well. Good pricing and quick when I need them. I would definitely recommend them to my friends. read more

I highly recommend Cool Time. I've used them before and they are very honest and know what they are doing. It is a family run business with a reliable father and son who do the work. I am very impressed with them and will definitely recommend Cool Time to my family and friends. They were also very accommodating and scheduled me in at my convenience, even though they were extremely busy. Thanks Robin! read more

my air conditioning broke last night and looked here on yelp and decided to give them a call and the lady that answer the phone (robin) was so nice explaining everything to me . The guys (gentleman) came right on time and fix it . Very happy for this family company wish them the best ! San Dimas Ghaly family read more

Call these guys!!! Cool Time is hands down the best HVAC Repair Company I've ever done business with. Clayne has saved us multiple times in extremely hot and cold situations. He takes his time to do the job right, is extremely affordable and makes time to help customers. I give him the highest of reviews and highly reccomend him to my family and friends. So thankful we found Cool Time! read more

Thank you Cool Time Air Conditioning. I have been dealing without air since Friday. I thought no big deal, I can get the parts and install myself right? Not. I went and racked down a motor and capacitor. Brought it home and really looked at it. Ok, I can mess this up better not. I called Cool Time Air this morning knowing that every AC company right now is buried with work with the heat wave. Robin is a life saver. She said she would try to work some over since we are local. She followed up with updates and kept me up to speed. She was able to get a team over. Nicest guys. They offered to install the parts I picked up and the others that I needed. I told them no, I will return my parts. I would rather them be able to stand behind their own parts. The pricing was VERY reasonable and they were done quickly and cleanly. Very impressed and will tell everyone I know to use them. Great local business. read more

The Cool Time Air Family always does great work and provides great service at a competitive price. Needed some work done and servicing on our unit and they once again go above and beyond in their service and fixing the issue! Great Job! read more

Great and efficient service. Was able to get my issue fixed the day of me contacting them, as they were already going to be in the area. They had all the parts on board, and were able to resolve my a/c issue (electrical fire) in less than an hour. I recommend! read more

Cool Time Air serviced me, they are professional, know what they are doing and give advice to what it needs in repairing your AC. Prompt, courtesy and very honest team, father and son. I would highly recommend to all my family and friends. I am very happy of their services and will continue your maintenance services in the future. Thank you Cool Time Air for your excellent services. Robin who took care of me over the phone has assured me that they can fix my AC, and they did! Thank you Robin. Marie S. read more

This is a great father/son team that provides good, honest, reliable, service at a fair price. My wife and I took the bait on another AC/Heating company that was offering a complete service special at only $77. The company did provide a complete clean out/purification of our 14 year old AC/Heating unit. However, this turned out just to be a screen to sell us an entire new system, via their sales team with whom we needed an appointment, at a base price of 10 K. They told us that our existing 14 year old system was only worthy of being trashed. I went to the internet, read the reviews and found Cool Time. I looked for a small local owner/operator company that had good reviews. Cool Time came out the very next day and fixed our AC for a little more than $500 instead of the almost $1200 that the other company told us that we needed. They assured us that our system was meant to last 30, not 14, years. They installed a carbon monoxide detector in case it did start emitting CO. They would be there to check on everything in a year without charging us the $16 a month "club membership" that the other company had wanted. If we did need an entire new system it would cost us at most $5800, not ten grand plus. Thank you Cool Time. You have earned my trust, respect, and gratitude. I hope this review might help save a few elderly, retired people such as myself who don't know where to turn. Please do yourself a favor and read the reviews before jumping or panicking.

I used Cool Time years ago on a previous residence. Now, living in a condo, the HOA had set up an AC check-up for the residents the first week of May. The technician asked how my AC had been working. My answer was "fine". He was stunned as the unit took 3 pounds of refrigerant. Shortly after, my unit began to freeze up in the excessive heat. I decided to call Cool Time. I am so glad I did. They discovered that my unit had too much refrigerant. They had to release approximately 3#. Fortunately, my unit has safety gauges which were shutting it down when the pressure built up. The unit was very dirty, so they cleaned it. They checked my air intake system and observed that the reusable metal screen was worthless. They replaced it with a regular filter to give me time to order a new one. I will file a report with my HOA and property management company. Thank you, Cool Time! read more

If you want quality service call Cool Time. We have used them twice the latest being today. Family ran business, father and son are the techs. Reasonable prices, gave us a senior discount (didn't know it was available), and other considerations - definitely appreciated and unexpected. Called last Friday, but because of the extreme heat wave, they were very busy and could not make it until hopefully Monday. When they could not make it Monday Robin called extremely apologetic and said they would be here Tuesday. Best customer service I have experienced in a long time. I highly recommend Cool Time, you won't be disappointed! read more

omg!!!!!! thank you mike robin and chris for the most awesome professional service of repairing our ac and saving our sanity. we truly appreciate your fairness and honesty!!!! and for saving us lots of$$$$$$.. you guys are the best!!! we highly recommend your services!!!! read more

My air conditioning on a rental property in Diamond Bar broke during a heat wave. Cool Time was recommended to me by a business acquaintance. Of course everyone in the AC business was busy including Robin, Mike, and Chris. Robin was very friendly and understanding of my sense of urgency. She listened, made me feel cared for, and scheduled Mike and Chris out to the property quickly. Robin not only had to work with me long distance, she gladly made the phone calls to the tenants and kept the communication lines open to all. Mike and Chris confirmed what 2 other companies did, the unit had to be replaced. I choose Cool Time not for the price (which was competitive) but the above and beyond service and the sense of comfort they gave me about doing the job well and standing by their work. I checked the Contractors License Board and they were in very good standing which added to my comfort. Additionally, I like supporting local family owned business. Cool Time has been in business for over 30 years as a Family owned business, again that speaks volumes to me. Mike and Chris got the job completed timely and with quality work. I am grateful for their service and would recommend them to anyone needing repair or replacement. read more
