To start off, I only post reviews when a service or product really sucks or when it's excellent, and I have to say 3HAC exceeded my expectations. I spent almost a whole month researching AC systems, brands, technologies, reputations and getting over a dozen visits and quotes. I had a budget of $13K for a new system and had narrowed the options down to exactly what I thought I wanted. After meeting with multiple AC dealers, I quickly realized that they were either eager to upsell expensive systems, didn't seem knowledgeable about the product they sold, seemed likely to "half ass" the installation and make a quick buck or simply didn't seem upfront and honest. After comparing multiple quotes, I finally met with Dan at 3HAC. He was punctual, polite, professional, knowledgeable and just an overall really nice guy. He didn't pressure me and didn't push expensive systems (he actually discouraged me from overspending on a very high SEER system because I wouldn't really recoup the difference in energy savings). He checked out my best previous quote and put together a system that BEAT it in specs AND price. I purchased from him a Trane system that was WAY better than the Carrier, Rheem and Goodman systems all the other guys were selling. He showed up right on time, did a great job with the installation and followed up after the job was done. Dan's wasn't the cheapest quote I had, but for the price I paid, he offered the best value, product brand reputation and had one of the best installer reputations and reviews. There is more to an AC system than Tons and SEERs, so don't focus on the "highest numbers for the lowest price" (salesmen can make anything look good on paper). A good installation is just as important too. The 3HAC website says they have a "long history of helping others honestly", and they certainly showed me that. As the saying goes, "you get what you pay for". But I think they gave me a little bit more for my money. If you're looking for a new system, a repair or simply maintenance, I HIGHLY RECOMMEND 3HAC.
