  • Miguel did an excellent job. He diagnosed the problem (two failed capacitors) very efficiently and solved it quickly. He's followed up to be sure the AC was blowing cold after fixing it. Excellent service!!!!

  • I highly recommend Miguel, he came out quickly during these extremely hot days and checked my mini-split without charging a service or inspection fee. They only added the amount of refrigerant it actually needed instead of trying to oversell me, which I really appreciated. Honest, professional, and fast service. I'll definitely use them again!
