Oleg helped me install a Google Nest thermostat. I didn't have to wait long for an appointment, and when he realized I needed a wall plate, he went to the store to find one. He made sure the installation looked good and worked right. I would definitely use his services again.

Seeing that GoTech Air had such positive reviews, called them for my wife’s employers home. Troubleshot system and corrected problem. Thank you.

Oleg did great work. First, he did a diagnostic at no charge. He then followed up with a few different options for a replacement air-conditioning unit. His estimates were much less expensive than those I received from other vendors. He was back within two days to install the new system. Very friendly and knowledgeable. I highly recommend. 5 stars.
