Van T. says, "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!!"See more
