John and Adan came out to our house to check our AC. They were respectful and pleasant. I highly recommend Sims for your AC needs. Both guys were knowledgeable and took time to exlpain whats happening with my system. They answered all of my questions. But my biggest take away was that John was honest. Will recommend you guys to family and friends. read more

I just had one of the best experiences with an HVAC professional ever. Dave from Sims Comfort Solutions helped me over the phone and text, walked me through what to do step by step, and saved me from paying a diagnostic fee for something that turned out to be simple. He was completely honest about the cost of me DIYing it versus what he would charge, and that kind of integrity is rare. Dave was patient, kind, and had amazing interpersonal skills. He could have easily come out, billed me, and called it a day, but instead he helped me troubleshoot everything without rushing me. Because of that, he earned my future business and all my referrals. I'm even sending him a thank you through Venmo because he truly deserves it. I wish him nothing but good karma. If you need someone trustworthy and genuine for HVAC work, call Sims Comfort Solutions and ask for Dave. read more

Great job at a great price. John was recommended to us by a friend and we will recommend him as well. This was a big project and he did a fantastic job. A true craftsman. Thanks John. read more

reached out to Sims Comfort Solutions during a stressful situation - I had a refrigerant leak at my rental property and needed an authorized Trane/RunTru dealer willing to do warranty work. After being turned away by multiple other dealers who refused to take the job because they weren't the original installer, Jon was the only one who said yes without hesitation. He was patient, professional, and genuinely willing to help even though I ultimately didn't end up needing the appointment. That kind of integrity is rare and exactly what you want in a contractor. Sims will be my first call for any HVAC needs going forward. read more

I have been using Sims for about 5 years. These guys are the best. They are honest and fair. Everyone that comes out to do work on my unit is knowledgable and courteous. John has always gone out of his way to get me taken care of during a couple emergency situations that came up during a heat wave. i have used several other companies and they have all been salesmen type personalities or shady looking guys. These guys are genuine old school technicians. Totally good people. read more

Jon and Dave went above and beyond with my installation. I had a new Trane A/C and Heater unit installed along with new Ductwork. From the fair quote to the quality insulation they were on time and kept me informed. I highly recommend! read more

Honest, professional, and a breath of fresh air, highly recommend! After a frustrating experience with All City Plumbing and Air Conditioning, who quoted me over $3,000 for repairs that did not make sense, I called SIMS Heating and Air for a second opinion, and I am so glad I did. From the moment he arrived, Dave was professional, knowledgeable, and incredibly thorough. He took the time to inspect my AC system carefully, explained everything clearly, and confirmed that most of the "urgent" issues I had been told about simply did not exist. My system was in good shape and only needed a basic service, which Dave completed on the spot for just $365. It is rare these days to find a company that prioritizes honesty and customer trust over upselling. SIMS Heating and Air not only saved me thousands of dollars, but also restored my peace of mind. I will be calling them for all future HVAC needs, and recommending them to everyone I know. If you are feeling unsure after a high-pressure quote, do what I did and call SIMS. You will not regret it. read more

Fast response and appointments. Professional and friendly service providers. Everything was covered under my warranty, so great value!

They came on Sunday morning after the A/C stopped working. Quickly identified and solved the problem. Very fair price and I trust them implicitly. Our technician was Jon, who was great. Definitely a very strong recommend from my wife and I. read more

AMAZING JOB!!! It is so refreshing to have a team who is respectful, responsive and reliable. We were having issues with our heater and needed some maintenance done on our AC as well. Upon my first interaction with scheduling and Bob who came to do the estimate, I was impressed. We are clean freaks at home and Bob was really thoughtful with wearing a mask, booties and bringing a blanket for his ladder, I really appreciated that. His quote was fair and I didn't feel like I needed to shop around. Jon and Freddy came to do the work on our home and they were equally as respectful and reliable. Give them a call for any of your AC & heating needs! read more

Every six months, we have our SIMS HVAC system serviced. Jon of SIMS is designated to do the servicing. He's puntual, courteous, and trustworthy. As my husband and I are elderly, Jon even offered to replace the filter in the ceiling. This was a great help to us! read more

The AC at our home went out in the middle of this crazy heat wave and the SIMS team came to the rescue. Their diagnosis was spot on, estimate fair and accurate, and the installation was flawless. They took the time to answer all of our questions and get us set up and educated on our new smart thermostat. Well done SIMS read more

Sims is a great company.They came when they said they were going to come. The tech was very nice easy to get along with and explained everything. He address the problem immediately. Also gave us some good advice about maintaining our air-conditioning unit. I was so pleased with the service. I highly recommend this company you won't be disappointed. read more

Have been using them since 2013. They have replaced the capacitor and provided other services. They are an open book about their service and parts and they don't try to pull a fast one which is why when my AC needs some work I call them. It's hard to get reliable service so it's nice when you get it. read more

Great experience! Dave was extremely helpful from the moment he picked up my phone call and scheduled me for same day service. Jon was sent out to fix my heater and he was just so helpful and informative. I would highly recommend this business to anyone! I have used their services over the course of several years and they never disappoint!!! read more

What can I say...I've Never Given any yelp review 5 Stars...but Freddy and Kory Got 5 stars because they Deserve it...... read more

Amid of social media boom, it is actually getting harder to figure out if a company is really good or a fake. I am glad that we picked SIMS for our new HVAC system installation. The team is professional, courteous, timely, honest, and price competitive in what they do - what more can I ask for? The positive feeling starts with the proposal process all the way through post installation. We had some weird p-trap issue, but the team is more than willing to be accommodating to address those. A good company is not defined when things go well but rather when things turn south. SIMS certainly checked off this box for us as well. We are still waiting for city permit, for which we don't anticipate issues (and frankly I have the confidence that even if there is any, SIMS will take care of them for me). Now that is a priceless feeling (and I am glad there are still plenty of honest and quality people exist after all the craziness of the pandemic and all the other sagas in the last couple years). Two thumbs up! read more

They installed a new system in my old house and did a fantastic job. I have them do an annual service on my new Glendora house, and again they are clean, well-organized, and fair. read more

The service guy that came out was very friendly and helpful with our problem. I would recommend this company.

Recently had two ACs and furnaces replaced by SIMS. Our units were 20+ and 15+ years old. We received 3 quotes before deciding on this company. They were straightforward, reasonably priced, and professional. In addition to the new units they recommended some upgraded duct work that greatly reduced the noise from the upstairs unit's intake vent. They were so patient in providing additional quotes as we explored a 2 speed and variable speed units as well as answered questions about different thermostat options. In the end we went with the Trane XR 14 they originally quoted us. It was the choice that made the most economical sense. On the install date they arrived promptly at 8am. Installation and clean up was completed by 5pm. Everything looks great and best of all, runs great. The new Trane condensers are so incredibly quiet! We are very happy with our products and the services received. read more

Sims Heating and Air is a wonderful company. I would recommend them to anyone who needs a new A/C system. When I first spoke to the company Dave, he was extremely patient and answered all of my questions. They were able to look at my unit the same day. The whole team are great people. They installed our new system in one day and their prices were reasonable. They guarantee their work/labor for 10 years. The crew goes above and beyond to make the system look nice. They install systems as if they were installing it at their house. Jon and Bob were always there to answer my questions and explained everything in detail. I would highly recommend their business or give them a shot to earn yours if you are in the market. read more

I've been using SIMS for over 5 years now. Initially, I was having issues with my airflow and wanted to know what the route cause was. SIMS came and discovered that not only did I have several tears in my existing ducting but also had a carbon monoxide leakage. They redid my ducting and fixed the carbon monoxide issue. Thank God my attic had enough ventilation for the carbon monoxide and did not harm my family in anyway. Most recently, SIMS installed a new 5-Ton AC unit with heater. The price was more than fair and quality of work was exceptional. Dave with SIMS answered any questions and concerns I had and was extremely professional. If your looking for a local family owned and operated company that provides quality work I recommend SIMS. FYI they didn't ask me for a review, I've just never been so cold in my house during a summer heat wave. read more

My AC unit broke over the weekend. I saw SIMS had good reviews, and I decided to give them a call, and I am glad I did. John was very honest with his assessment of my problem and very fair with the price. They definitely got a customer for life with me. Thank you so much! read more

Sims is truly honest and an excellent company to use for your HVAC system. Jon arrived on time was very friendly and explained everything that was necessary in order to fix my problem. He did not try to sell me anything extra or try to over charge me for the work that was done. I will recommend Sims heating &air to all my neighbors, friends and family. read more

Sims came highly recommended from a work colleague and now I see why. We called them because our heater was acting up. John came out the next day and he couldn't have been any nicer. The system is up and running without costing us a fortune. Call them. As someone else said, they are professional, courteous, timely, and honest. Thanks guys. read more

This company is just MARVELOUS! I have my 2 AC units moved from the back of the house to the sides, back in January of 2017. I have one of the "Super Homes" by Lennar in Rosena Ranch and it was a challenge to get those units moved from the backyard where the builder set it, to the side of the house which was suitable to get to maximize the area in your backyard. I have researched a lot of HVAC around my area, most especially in Yelp. SIMS had a great rating, so I called them up. They did not disappoint! Spoke to Dan, the owner of the the company, and he had tremendously worked with me very professionally, and also in a very personal level. He understood the project I was about to do, with one of the concrete company that I also yelped, and knew the timeline I was trying to hit. Price was very reasonable! His son, also partner, John, and Isaiah have came to the house and did a very thorough job. They moved the copper tubings, and electrical from the back to the sides; recharged my lines; test and ran the system multiple times. and Viola! Such professional work! Definitely, my "go-to" HVAC company. I have recommended them to my neighbors around that wanted to do their AC Units moved as well. Thanks Dan, John and Isiah!! May God continue to Bless your company! read more

These guys always come through. As I have stated in previous reviews I have never dealt with a company so reliable and customer oriented. I would give them ten stars if I could. read more

If I could give them 6 stars, I would. Our air went out today in 100 degree heat, and we called another company who told us we needed an entirely new HVAC system. It didn't sound right, so I asked my office who we use there and they referred me to SIMS. Bob came out the same day we called, and determined that we just needed a repair. It was very reasonable, and within an hour of his arrival we were back in business. They are courteous, professional, and most importantly, honest. Quit thinking about it and hire them already! read more

After 30 years with our original AC unit and furnace it was time for an upgrade. After looking on yelp for a HVAC company we saw SIMS had the best reviews. They did not disappoint. Bob came in and did a diagnostic check which was very informative. The same day Dan sent me a detailed estimate with options ranging from low, mid, to high. We went with the XR14 for our 1400 square foot house. The following week they're team came in and did and absolutely fantastic job. From the cleanliness to information and politeness. They are the type of company you would want to deal with for years to come. Freddy was very respectful in asking permission to do his work. I did not get the name of the guy working on the furnace but he was great as well. I just can't thank them enough. read more

We had SIMS heating and air replace both of our aging heat and AC units. Short story - We could not be happier with SIMS. Fair, honest, and friendly group. What more could you ask for? When we were looking for a company to replace our systems I did what you are probably doing - spending an entire day or more pouring over reviews and websites trying to find the best systems and installers. From my experience with them in January of 2021, you can stop looking and researching and just call these fine folks at SIMS. I left a much more detailed (and book-length) review on Google. Go read that if you have 30 minutes to read all I wrote over there. :) read more

I can only give this guys 5 stars, even though they sure are a 10 star caliber! SIMS Heating and Air is beyond incredible. They were part of a three different companies that showed up to my rental property, however, SIMS were the first and only ones that were on time, they were the only ones that did not try to up sell me with new installs and were very competitive with pricing. On top of that SIMS listened and did exactly what I've asked of them, to me honesty goes further than service. Jon showed up three times to make sure my install was done properly and considerate of my time If you're reading this don't waste your time contacting other HVAC people, trust me, you'd be glad you did. read more

7/2017 I had ac repair by the same group, I left a message for them on their phone service and the boss stopped by my house and diagnosed he problem quickly. Then they came the next day and John did and excellent job. John and this company are highly trained professional and I recommend them to and home owner with a/c problems Excellent work. I'm a middle class income worker and I trust this team. They have respect for your house, they wear shoe covers and are well prepped. Jon came in very respectful, and immediately got down to diagnosing my furnace problem. Isaiah(sp?) finished up the job by getting the replacement part and finished the job. The company threw in a replacement air filter which I am thankful for. Total job was $431. Part replaced was circuit board. Thank you. read more

By far the best company I have ever worked with. I had a chance to engage with Dan, Jon and Bobby. Some of the nicest, professional, fairest and knowledge folks based on my search for a AC company. Dan was very responsive and willing to work based on my needs. Bobby, Jon and their team came out and covered our carpets to avoid getting them dirty. They were in and out and installed two ac units in less than a day. I had a small issue a few months later and Bobby came out to resolve the issue no questions asked. They are so confident in their work that they offered me a 10 yr labor warranty. If your looking for a HVAC installer, stop looking and contact them. You will be glad you did. Thanks Sims heating and air. You saved us during the brutal summer heat. read more

Sims Heating and air simply the best, fast response I called them bc my unit outside wasn't working I thought maybe it was the fan , I called Sims left a message and the next day received a call asking me what the problem was I described what was going on they said ok will be by tomorrow 10 am they were hell yeah they mean business Bob came to my house performed diagnostics found the problem my Capisatator was bad fixed it in no time tested it checked my coolant added some then checked the temperature to make sure everything was working properly and it was so greatful good job guys I've been a customer of Sims now you know why keep up the great job !

It was the online reviews that led me to SIMS and they were right. Five star service from the entire team. The heat this summer is ridiculous but I'm turning on my A/C with confidence. Thanks to SIMS, hot girl summer is a good thing. Happy to have found this local, family business. read more

SIMS installed 2 HVAC systems at my house in 2017 and 2020. It was a great experience. A couple weeks ago, the heater stopped working on one of them. They were out the next day and fixed the problem - no charge as it was still under warranty. Yesterday they came out to do routine maintenance on both units. Once again, the staff are very pleasant and professional - John, Freddy, and Dave. They also use a texting system for appointment reminders, plus they text you when the technician is on the way. Those little things make a difference. It's always such a pleasure working with SIMS. read more

Dave responded to my request for A/C repair lightening fast! He kept me updated on what time his service technicians would be able to come. Freddy and Eric were both professional and respectful and stayed until they were sure the A/C was working properly. They even changed my air filters! I would definitely hire Sims Heating and air for all of my HVAC needs read more

I originally called SIMS in late 2015 to get an estimate for a split system - for the house I had just purchased. Dan showed up at the house and was very friendly and professional. The estimate was very good in comparison to a few others I had received during that time. I decided not to have the new install done at that time due to many other projects that were requiring my attention and $$. Fast forward 4+ years and I once again called Dan out to the house for an estimate. Again, he was very professional, friendly, and provided a very reasonable price for the system. It was finally go time to replace the 40 year old system! Dan was very informative on how the process would go, when exactly it would be done, who would show up to the house to perform the work, etc. Last Friday was the system removal, this past Monday they installed the condenser unit and today (Thursday) was the coil and furnace. It was typically a one day job but they were flexible and came back a second day because I wasn't ready with the work I needed to complete first. And Dan was nice enough to offer to bring me a few space heaters to assist in keeping the family warm while the system was down. Bob and Freddy teamed up to complete the job, with Bob doing most of the furnace install. I hung around like a helicopter because I'm always eager to learn something new about the trade. And Bob is a cool guy who went the extra mile to make sure that all of my questions were answered and explained every detail about the system. The end result was great! In summary, if you need a new system, call SIMS. I'm glad I did. The price was on point, the customer service was exceptional, and the new system looks and works perfectly. Thanks Dan, Bob, Freddy, and Jon. read more

After getting 4 quotes, I decided to go with SIMS to replace our 31 year old AC, furnace, and ducts. After Bob came to assess our HVAC system, I received an estimate from Dan, the owner, the next day. Dan answered all my questions via email. He was quick to respond unlike one of the HVAC guys that gave me an estimate. His pricing was reasonable. We had to wait 2 1/2 weeks for installation, but it was worth the wait. The team worked from 8am-3pm non-stop and got the job done in one day. They were all friendly and professional. My husband and I are very pleased with the results. I can't thank the SIMS team enough for all their hard work. I highly recommend them if you're in need of an HVAC system replacement. read more

SIMS saved us from having a really hot day! This is the second time we've used this company and I can tell you that they are reliable, and very prompt. We called Dan and told him that our A/C didn't work, and in less than an hour he sent his technician Jon to fix the problem! Two hours later the A/C worked perfectly. I'm not familiar with the terms of what they did and how they fixed it, but it felt really good to know that it works! We will continue to use this company and we will refer customers their way! Great people that provide excellent service! Thank you Jon, and than you Dan! read more
