Carlito performed an outstanding job accurately diagnosing my heat pump AC issue and repairing it quickly. My AC unit was hissing and was no longer cooling effectively. I received a $2,500 repair quote from a different company just a few days earlier and I contacted Carlito for a second opinion. The other company said I had a leaking TXV valve and that it would take two technicians 8 hours to complete. I am no expert, but that seemed high. When Carlito came he performed a thorough diagnostic and determined that the leak was just from a tiny valve in the outside unit - not the TXV valve. He made the quick fix and recharged the refrigerant. Now the AC is working like new and I got the issue repaired for a fraction of what the other company would have charged. I am glad he was completely honest about my AC issue and gave me a very fair price. He also arrived exactly on time and was professional. I am recommending him to my friends and neighbors. I will also call him for future AC maintenance and cleaning jobs.
