"II rarely write reviews and I thought writing about 1HARO1 LLC is very important, as it is hard to find knowledgeable, hard working and genuinely honest companies dealing with HVAC systems is very hard to find. during the last 12 years of so, I contracted 1HARO1 LLC on three Single Family Home Projects (built brand-new single Family Homes) and a few remodels in South Bay. They consistently delivered top-notch workmanship and service. Always done a very high-quality work (installing Central Heating and Air Conditioning systems, Duct work, Proper zoning, etc). Ernesto Haro (owner) is very knowledgeable and quality conscious. Their pricing is reasonable and justified. Most sensitive (and very important) character of any services comp-any is not just getting the installation done, but providing services after that. Ernesto is always reachable, very responsive and jumps-in to address any issue (irrespective of the work involved- big or small) right-away. I don't think any other company or firm comes closer to 1HARO1 LLC. I recommended him to my colleagues and family friends, and always got an excellent feedback from all of them (no exceptions). I can confidently say I will engage him/1HARO1 LLC for any future projects, without any second thoughts."

"John Alanis and the Alanis Air crew were a pleasure to work with. Our 40 year old furnace needed replacement. We called John at Alanis Air and he responded immediately. He came to the house, diagnosed the situation and recommended a heat pump to take advantage of our solar panels. John and his crew showed up the next Monday and completed the job in two days. John and his crew were very knowledgeable and efficient. They covered all furniture and floors and cleaned up after completion of the job. We were very satisfied with the price and the work was exceptional. I would recommend Alanis Air to anyone that needed HVAC work."
