DO NOT TRUST THIS GUY!!! I hired David in March 2022 to check my HVAC for a loud noise. He came and checked the system and stated my motor was bad and my unit was old and need to be replaced. I trusted him and went ahead and replaced the unit. The next morning the noise came back. I was very upset after paying him thousands of dollars for him to replace my HVAC. It took a few days but I figured out the noise was a wood pecker. I sent a video of the wood pecker on my roof to David and asked him why he said it was a bad motor. He never responded to my phone calls or text messages after that. He knows he did wrong to me. DO NOT HIRE DAVID!! - Sung Lewe in Fairfax ([email protected])
