My experience with this company was nothing short of AMAZING!! I’m literally In shock right now at how much integrity and professionalism they demonstrated.
I had a bit of a touchy situation where a rodent got into my AC condenser outside and I had no clue how to manage it. I used Thumbtack to find a couple of contractors, and the first company came out and quoted me over $3K to clean my condenser and cleanup my air ducts, and tried to scare me into a $10K revamp of the entire system in my attic saying that the air quality was harmful to our health. I was a bit weary and decided to get a second opinion...
Sydney contacted me from One Season, and assured me that they would be able to take a look and take care of the situation. She was extremely kind and understanding given my concerns.
Aubrey was my technician and as I mentioned above, was just amazing. Helped me with disposal of the critter, cleaned out my entire AC condenser and told me he would include it with diagnostic fee, which technically he didn’t have to do since the system was still working, so he applied that fee to the clean up. He still took everything apart and did an inspection and checked everything out for me to make sure it was running properly. Was very informative and educational and told me signs to watch out for as my system is approaching 20 years old. Did a full inspection of my attic system and did point out some things that I might want to take a look at in the future, but never once tried to push a sale, install, or upsell anything.
As is normal with any maintenance company, he did introduce their maintenance plan to me which I welcomed since I know my system is aging. And upon signing up for the annual maintenance plan, he actually waived my diagnostic fee… so he didn’t even charge me for my service call! I mean my mind was just BLOWN! Rodent gone… Check! AC condenser clean… Check! AC in good working order… Check! Things to watch for… Check! Peace of mind… CHECK!!
I went from a $3000 scare tactic quote saying the air quality in my home being harmful to my family’s health to an honest assessment of my home’s system, and what I could expect in the next few years given the age of the system. I feel so much better now, and can also prepare myself!
Thank you, Aubrey and One Season, so much for the amazing service and the integrity and honesty that you brought to this job. I am so very grateful to have found you. You’ve got a lifelong customer in me!!
100/10 HIGHLY RECOMMEND!!

Aubrey came promptly. Let me just say he is one of the most professional, honest, friendly and competent individual I have dealt with. He diagnosed issues in a transparent logical manner, explaining every step clearly. He gave some valuable pointers and my AC works fine now. All of it for the simple visit fee. This company was actually my second opinion, and ended up saving me thousands of dollars from false estimate by a previous company. If you are looking, do not hesitate. Believe all the great reviews because they are absolutely true. This is the company with integrity, skills, and professionalism. Aubrey and One Season have a customer for life in me!

I genuinely had a wonderful experience working with Aubrey. I appreciated how he took his time to explain every aspect of the inspection and tune-up process. As a new homeowner, learning everything I possibly can about different systems and such in the home are so important and Aubrey made that process seamless for our HVAC. He truly went above and beyond, and I appreciated the price transparency (given how easy it is to get scammed nowadays). Even the customer service was unparalleled, so shoutout to Sydney for being great to work with. I would highly recommend this company and would easily work with them again.

We recently had HVAC work done at our home and had a great experience from start to finish. The team was professional, on time, and very knowledgeable.
What really stood out was their customer service. From the first call to the final walkthrough, they were responsive, courteous, and easy to work with. They took the time to answer all of our questions, explain the process clearly, and made sure we felt comfortable every step of the way.
The work itself was completed efficiently and cleanly, and everything has been running perfectly since.
It’s not always easy to find a company that delivers both quality work and great customer service, but they definitely do. I would absolutely recommend them to anyone needing reliable HVAC service.
FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We believe in 100% transparency. All pricing is provided upfront with clear, all-in options tailored to your needs, so there are no surprises. The price we quote is the price you pay, even if unexpected challenges arise during the job. We never add hidden fees or adjust pricing after work begins. We also offer seasonal promotions and maintenance discounts when available, and we’ll always explain them clearly before you decide.
What is your typical process for working with a new customer?
Our process is thorough, professional, and educational. Your technician will introduce themselves and perform a comprehensive, start-to-finish evaluation of your entire system, not just the immediate issue. We focus on identifying root causes so your comfort isn’t temporary, because comfort only has one season. After the evaluation, we provide a clear system status report and multiple options, allowing you to make an informed decision that fits your needs and budget.
What education and/or training do you have that relates to your work?
Our team is NCI (National Comfort Institute) trained and certified, which means we specialize in airflow and air balancing, one of the most critical, yet often overlooked, parts of HVAC performance. Proper airflow is what allows your system to heat and cool evenly, operate efficiently, and avoid unnecessary strain that leads to breakdowns. Without correct airflow, even the best equipment cannot perform as intended.
In addition, we are one of the few contractors in Southern California that participates in ACCA’s Quality Assured (QA) program. ACCA QA ensures systems are designed, installed, and verified to meet nationally recognized comfort and efficiency standards, not just manufacturer minimums. Together, NCI certification and ACCA QA training allow us to look beyond the equipment itself and ensure your entire system works as a complete, properly balanced system for long-term comfort and reliability
