5 Stars 100% I…read morecannot recommend United Heating and Air highly enough! Last year, United Heating and Air installed two new air conditioning units and one furnace at my home in Stevenson Ranch, California. From start to finish, the experience was outstanding. Their pricing was the most competitive I found, and the quality of the installation exceeded my expectations. Because of that experience, I hired them again to replace the HVAC system at my condo in Wood Ranch, Simi Valley--and once again, they absolutely delivered. One of the biggest challenges was that my condo has no backyard access. Rather than trying to force the unit through or risk damage, United Heating and Air came up with the perfect solution: they brought in a crane and safely lifted the new AC unit directly into my backyard. The entire process was handled professionally, efficiently, and with great care. I also want to recognize the owner, Peri, who was incredibly responsive and made sure every question and concern was addressed. It's clear that customer satisfaction is a top priority for him and his team. If you're looking for honest pricing, exceptional workmanship, and outstanding customer service, I highly recommend United Heating and Air. Whether you need an AC repair, a complete HVAC replacement, or a new furnace, this is the company to call. United Heating and Air has earned my trust, and they will be my go-to company for all of my heating and air conditioning needs. Thank you, Peri and the entire United Heating and Air team, for another job well done! Thanks! Jerome

What crooks!!! I had an air conditioning issue at my house with water leaking inside the house when…read morethe ac would be turned on. They came over the next morning. Joseph seemed like a pleasant enough guy. However, he quoted me a repair price of $6,500 to replace the coil box inside the house and the outside unit! He told me the tray inside the coil box was probably cracked. Eventually, his boss talks to me on the phone and says he can lower it to $6,250. I tell him I need to think about it. I end up getting two other estimates. Both said the problem was clogged pvc pipes. I end up having it completely resolved for $365. Can't trust them. Get at least two other estimates or at the very least don't bother calling them.

From the very beginning, this company was incredibly responsive and easy to work with. I started a…read moreproject through Yelp, and through the messages in the app, Andrea C. was able to help get us scheduled for a same-day appointment--which we truly appreciated, especially in 90+° weather! I'm sure they had many other clients dealing with similar HVAC issues, so it was such a relief not to have to suffer through the heat all day. Andrea was always quick to respond, easy to communicate with, and made the scheduling process seamless. They were also able to provide a diagnostic quote upfront, while many other companies would not give any estimate until they came out and saw the issue. I really appreciated that transparency. Even better, the diagnostic fee was applied toward the repair that was needed, which was another huge plus! Shortly before arrival, we received a text letting us know Marcelo was en route, including his photo, followed by a direct phone call with an estimated arrival time. Lemme start off by saying Marcelo was such an amazing technician! So now let's get into the meat our of experience. We were having an issue with our AC not blowing cold air, and after some quick troubleshooting, he already had a pretty good idea of what the problem was. Of course, he then followed up with his handy-dandy tools to confirm his suspicions! What really took the experience from good to exceptional was how helpful and thorough Marcelo was throughout the visit. While working, he shared lots of great tips with my husband about maintaining our AC unit, helping prevent future issues, and even reducing allergies in the home--which truly made a difference. He was also incredibly patient with all the questions my husband and I had, not only about the issue at hand but also about our other HVAC-related questions. We also really appreciated how respectful Marcelo was of our home. As an Asian household, we really value that extra consideration, and when he came back inside to check that the cold air was coming out after the repair, he immediately put on his own shoe covers without us even having to ask. That was a huge plus for us, because so many technicians forget or just don't care which was definitely not the case here! If possible, I definitely recommend requesting Marcelo to come out and assist. He is so nice, genuine, knowledgeable, well-articulated, and well-spoken. Marcelo, thank you sooo much again for all of your help--and Andrea, thank you for helping us get everything scheduled so quickly!

When my AC completely failed to start on one of the most brutal, scorching days of the year, I was…read moreat my wit's end and had no idea why my HVAC system had given up. I called Southwest Heating & Air Conditioning, and Stephane--the owner himself--stepped up immediately and showed up personally to help. He gave me an arrival window of 11:00 AM to 2:00 PM, but recognizing how miserable the heat was, he went out of his way to arrive extra early just to make sure I was taken care of. That level of hands-on, prompt care was just the beginning. When Stephane inspected the system, he uncovered a nightmare: a completely botched, unpermitted, and code-violating installation left behind by my previous contractor. To say I was overwhelmed is an understatement. Fortunately, Stephane's expertise, honesty, and incredible attention to detail completely changed the game. He didn't just diagnose the technical failures, hidden structural damage, and airflow disasters--he stood by me and guided me patiently through every single step needed to hold my previous contractor fully accountable. I honestly would have been completely lost without his guidance and genuine support through this whole ordeal. It is rare to find a business owner who rolls up his sleeves, shows up personally, and combines this level of technical mastery with such profound integrity and care. Because of everything he did for me, Stephane and his team have earned my absolute trust and loyalty for life. They are my go-to HVAC company moving forward, and I am proudly handing out his name to every friend and family member I know. If you want honest, elite-level work done right, look no further than Southwest.

Fixed our AC on short notice during a busy summer rush for them. I inquired in the evening on a…read moreThursday and the technician was on site on Friday afternoon to do the diagnostics and perform the repair. He was running behind and missed the window they had said we should expect him in, but honestly I understand that with these kinds of jobs, it's tough to estimate accurately how long it would take from one site to the next. Everything went smoothly and the repair was performed in under an hour. Priced fairly and Juan seemed like an honest guy. Didn't push to upsell on unnecessary services, but did point out other pain points in case we wanted a more thorough service. Was understanding when I declined. He was also knowledgeable about the craft, which is what I cared most about (not every company sends someone qualified to fix your appliance/ hardware - this one did). AC works and our dogs are happy. Thanks again, Southwest H&AC.

Scott, the owner of 20th Century Air, installed my HVAC system in 2015. He and his team did an…read moreexcellent job and it has performed well for the past 11 years. Today his team, Juan and Adrian, came out to diagnose an issue with the air conditioner. They arrived on time, they were efficient, and they were friendly. They identified the problem, replaced the condenser pump and added one pound of refrigerant and the system is back up and running. They were so quick to respond when I reported the problem yesterday evening (coming out first thing this morning). They were good about wearing protective booties (without even being asked) when they came in the house, and they worked cleanly. I feel the charges were fair and reasonable. I would highly recommend 20th Century Air. They stand the test of time and they are an honest company.

[UPDATE AFTER BUSINESS RESPONSE]…read more The owner's response is completely misleading and ignores the core issue. 1. Unauthorized Charge: They failed to address why they charged my credit card an ADDITIONAL $450 without my consent instead of issuing the agreed $150 refund. That is fraudulent billing, not a "pricing misunderstanding." 2. Shady Pricing & Diagnoses: They claim I had "unreasonable expectations," yet their technician initially quoted $1,562 for a TXV replacement, dropped it to $1,000 on the spot, and then admitted it wasn't even broken once I showed proof of warranty. Charging $200/lb for refrigerant and $100 for a $35 part speaks for itself. 3. "Threatening" Claim: Demanding a legal refund and stating I would file credit card disputes, CSLB, and BBB complaints for unauthorized charges is NOT a threat--it is my legal right as a consumer. I have uploaded actual bank screenshots and invoices above as proof. The credit card disputes and state complaints are actively underway.

The reason why I'm reviewing this now is because I waited for one year to see if the mini-split…read moresystems is in good working condition and I'm pleased to say that how amazing the system is running now even though we didn't run often. Last year we did a lot of research to get a mini-split ac unit for 3 bedrooms and a living room that would save money, good quality system and reliable installation from the professionals. We got quotes from 6 vendors and Temp Air Systems was the best of all. Jason was excellent and he explained in details the mini-spits ac which was the best option for us. They are licensed installer for Mitsubishi ac systems and when you go with them, the warranty guarantee goes up from 7 years to 12 years with of course there's a catch which you must maintain your systems annually with Temp Air to qualify to 12 years system warranty. I'm very pleased and happy with Jason and his expertise in the ac systems to help us guide in making the right decision and Angel as well who was leading the crew was excellent and extremely knowledgeable and experienced professional installer. His crew was great as well. We got a rebate for removing the heat furnace and a tax credit for heat pump. Amazing company for providing excellent workmanship and customer service in the front office. I would highly recommend this place if you're looking for mini-split systems. Look no further , Temp Air Systems is very good with mini- splits ac systems. Call them up and get a quote. You won't be disappointed. Happy journey!

We were able to negotiate with the seller because of this discovery, and Matt's work helped us secure enough in credits to get a new electric smart HVAC system, ecobee. During install, they discovered a vent was missing and promptly added it. Their crew was courteous and helpful, and took great care to leave my property in excellent condition. They went above and beyond in their work and their customer service. They were so great that my neighbor across the street hired them immediately after. Furthermore, I just had my HERS test, and it passed with flying colors, so the work was done exceptionally well. The inspector told me this system increases my property value - something I am relieved to hear, after so many other unexpected new home expenses! I actually look forward to having them help me maintain my exceptional new system throughout its (what I presume to be) long life. I highly recommend them!
