Report
Called at 4:00 in the afternoon, not expecting them to arrive until the following day. My air conditioner was not working and it was very hot in my house... They showed up within an hour and fixed my air conditioner quickly. Everyone from the office and repair person were friendly. They also do our bi yearly maintenance. They go beyond my expectations and I highly recommend this company.

My A/C went out and I wasted 4 days with an unreliable AC company out of SA. I then called a local dealer, 4 Winds AC And Heating in Castroville. They even loaned me a room AC to use until my system was installed! Mason came immediately and determined I need new a new unit. He had knowledge of the products and was helpful in making my decisions. I found them to be fair on pricing. They installed when they said. Cindy from the office even came to my home afterwards to bring the paper work, say thanks for the business and for me to call if I had any questions or needed anything.

My AC broke in the TX heat our regular AC compliant came out and said it couldn't be fixed wanted me to buy a whole new system. I called 4 Winds fora second opinion. They made me a top priority and came right over. Cindy works the phone was sort helpful and went over everything before anyone came over. When Lewis got here he was professional and quick he gave me several options and contingencies plans. He had me back up and running in about 30 mins and saved me a ton on money. I'm dumping my other company. Give them a call 4 Winds has your back!

We hired 4 Winds AC & Heating and got on the Primo they have to come out twice a year, summer & fall for maintenance. They are very professional and informative. They went over everything with us. Thankfully we did not have any issues. But when I did mention that our filter is so difficult to find they offered to sell us filters. They sell them too all sizes. They team up with a local vendor that makes and sells them. Even better! I highly recommend 4 winds AC & Heating. They also service emergency situations, commercial buildings, mini splits etc.
