All Four Seasons AC & Heating was responsive, fast, and fixed our dire problem in their first visit. Worst case scenario for us: in the midst of one of the hottest longest heat waves in LA history, over a holiday weekend, one of our outdoor fans broke down. We requested four bids on Angi and submitted to American Home Shield. ONLY All Four Seasons responded, on a Sunday no less, and we scheduled a visit, on the Wednesday after the Labor Day weekend. They showed up on time, in 105 degree weather, ran some tests, diagnosed the problem, and were able to fix the problem within an hour. American Home Shield won't even send someone for at least two weeks, and then they add another two weeks to order parts. I would recommend All 4 Seasons to anyone in a fix.

I called in to the office and spoke with Catarina. She was very helpful and informative. Since I was a first time caller, Catarina gave me a detailed quote and broke down everything from A to Z. After calling around different companies and speaking with a few very rude and unwelcoming people, Catarina was definitely a breath of fresh air, I am absolutely moving forward with my services from All Four Seasons.

My Carrier unit was due for it's maintenance so I called All Four Season's A/C and Heating. My wife and I were a bit concerned about having someone come and work on our unit during Covid but we were EXTREMELY happy with the precautions and service we were provided. The technician (Jesse) came on time, he was dressed in protective gear and was thorough and knowledgeable about our unit. He had asked us several times if we had any questions he could answer and was happy to explain to us how he serviced our unit (Carrier with Zones). I highly recommend for All Four Seasons if you are looking for an honest and reliable company.

All Four Seasons is our go-to company for our heating and cooling problems. This was the third time we've used them in six years, and couldn't be happier. Our AC stopped cooling on July 4, and by Monday, we were melting! I called first thing Monday morning (Kaitlin was very helpful) and we had a technician out by the afternoon (15 minutes into the two-hour window given). Jessie checked out our system, made suggestions, and gave us the best-case-scenario/worst-case-scenario. We followed his suggestion to start with a full-system pressure check (which would have been a few hundred dollars and taken several days) before jumping to a system replacement, in case the problem wasn't fixable. We scheduled the test for the following day (today) and was given a 1.5 hour window. Jessie again showed up 15 minutes into the window, and began the process of the test. He was able to see right away what the actual problem was, and was able to fix it immediately, instead of having to run the entire test. We were anticipating spending several thousand dollars on a new system, or at least a few thousand to do the test and fix, but we ended up spending a fraction of that with a much more minor fix, and we have cool air again. I have always trusted the technicians from this company and have never felt they were trying to up-sell me on fixes that weren't necessary. I would highly recommend them!

Response from All Four Seasons AC & Heating

"Dear [Member Name Removed], Thank you for your review, customer satisfaction is very important to us. We apologize that you feel your experience with our company was unsatisfactory & our technician was unpleasant, we were unaware you felt this way, our goal is to always help our customers at the best of our ability. We initially recommended to repair your Furnace and unfortunately due to the age of your equipment multiple suppliers advised us that the recommended replacement part was no longer manufactured, after providing you with this information, we offered to send you an estimate to replace your Furnace and include a discount for the installation due to the circumstance, which you agreed to receive. We did try to Follow-up with you regarding the estimate but never received your response. Once again we apologize, if there is anything we can do to make you feel better about your experience with our company in hopes to earn your business in the future, please let us know, Thank you."

Pricing was competitive with two other bids. Owner was available for contract and product questions and adjustments. Installation was on time, quick, and professional. The system is performing as promised and is a big improvement over our previous 20-year-old system.

I just had my entire HVAC system replaced. I've used All Four Seasons for repairs, and to replace my duct work, in the past. They are always professional, knowledgeable, trustworthy and fair priced. So when it was time to replace my HVAC system I went right to him. They were, of course, all of what I described. They came at 8:30 AM and worked very hard, and finished by 4:30 PM. Ethan is always great, and hires quality people. They laid down clothes to protect my house, and completely cleaned up, including vacuuming, when they were finished. I love my new Carrier HVAC system. I totally recommend Ethan and All Four Seasons Air Conditioning and Heating.

The service guy came on time and identified the problem promptly. He charged me $500 for parts that were available in my local Home Depot store for $30. Poor technician showed me the rates in the company charge sheet and he had already quoted me lower rates than the charge sheet. I feel cheated by All Four seasons A/C and heating
Response from All Four Seasons AC & Heating

"Thank you for taking time to write the review. We at All Four Seasons A/C and Heating would like to take this opportunity to respond to the previous post. We pride ourselves on the highest levels of professionalism, dedication and integrity. Our reputation and track record speaks for itself. We take every review very seriously and felt compelled to respond accordingly. Upon receiving the above review, we shared and spoke to our technician and office staff about the incident. You had called the office on Sunday morning on Labor Day weekend (heat wave) requesting a same day service. You had mentioned to the office staff your wife is pregnant so to us that is an emergency call and we had to help you since you could not find another company to come the same day. Upon arriving on time our certified technician could diagnostic the issue with your ac. The technician went over with you what repairs needs to be done and what will be the cost. You agreed to have the technician start the repair. All four seasons ac and heating is a licensed company and all our technicians are certified and receives top of the line training. We at all four seasons have a price book we use to all customer no matter how big or small your house is. The price book was created to be fair to our customer and for us to be able to keep our business going. Every one of our customers will pay the same price. We don't make up prices. Yes, sometimes the prices charged for a repair may seem higher than customers expect. The total price for any repair not only covers the cost for the part, but also the expert diagnosis from a qualified technician to determine which part needs to be replaced. In addition, our service vehicles usually keep these parts in their truck stock, which allows our NATE Certified Service Technicians to repair the system and get the customers cooling system operating as soon as possible. I think that anyone who were to calculate the time that it requires to diagnose the problem, then have to acquire the part, and then install it would agree that not only are our prices fair, but are also comparable to most other reputable contractors. Keep in mind we are not a wholesaler we do not sale parts we provide you with great honest service. I am sorry that we were not able to meet your needs at your price point but in all fairness the technician never pressured you do the repair nor you declined the repair. We always require a signature by home owner to ok any repair. Our office did attempt to reach you via phone to discuss this issue but we were unsuccessful. We thank you for taking time to write the review and hope you will return our phone call. Thank you for choosing Al Four Seasons AC and Heating"

It was a Sunday afternoon and 105 deg, outside when I noticed that the interior house temperature had risen to 81 degrees. The compressor wasn't working. I had used All Four Seasons A/C before and was very happy. I called hoping that there might be someone there on a Sunday afternoon. There was! Carlos was working and said he'd be at the house in 25 min. He was there as promised and fixed my A/C in no time at all. I am so grateful. The A/C unit has served me well for many, many years and Carlos found that the electrical units inside the compressor were fried. He replaced them in no time at all and gave me the Angie's list discounts as well. Great service once again.

The quality of their work was outstanding. The areas they worked in were just as clean as they were when they arrived. I would recommend them to anyone, and am happy I have found a new A/C & Heating company that is local, reliable, and reasonably priced for the area I live in.
