We loved his professionalism, knowledge & the quote was very reasonable. It was Vadim we hired for our ac and heater repair service needs. As he started the repair, I could see how careful he was and how expert he was in checking up the parts to ensure the best quality. After the repair, he then had the testing process to see if it's working well or not. I was absolutely amazed. It was running back to normal and no more issues occurring. Perfect repair! Thanks for your best assistance.
