I sent a message via Yelp on a Sunday night and they immediately scheduled our oven troubleshooting for Monday afternoon. Their front office staff is incredibly responsive! George (technician) arrived timely and was very thorough. He explained things to me every step of the way. He is approaching this very methodically - ok, so it's not the igniter, let's look at the next link in the chain... I saw George called out by name in other Yelp reviews, and I understand why he comes so highly recommended! He called the manufacturer to discuss his findings, but the manufacturer tech team wasn't available. He let me know he would be calling them again in the morning and that he would reach out to me with an update. I've had plenty of negative or so-so experiences with other service technicians from other companies. This experience with George / Astera is so positive that I'm posting my review even before the service is completed. Astera will be getting first crack at all of my appliance and HVAC service calls going forward.

This past summer another company came to fix our broken down air conditioning unit and offered a new unit as the solution. Good shield team cleaned up the unit, identified what needed fixing, did that and it's been working all summer. So even if it eventually dies, I know whom to trust. Can't beat 300 over 5k. Today Jon was extremely detailed in his analysis of the issue. Shared with us the problem plus the solution sand have us realistic expectation of the furnace through this winter. They'll be back next week to repair but he jigged it to work until he can return.. Love em

From the moment I submitted a request to talk with someone, I received prompt and clear communication from everyone I worked with at Leith. They stopped by my home to learn more about my home, family, and needs. Jake provided me with clear options, answers to my questions, and recommendations that matched what I was looking for with the project. They gave me options and quotes that let me feel in control of a big purchase. I never once felt pressured into spending more than what I was looking for and they were flexible to my needs instead of the other way around. They completed the project quick and the new unit worked great. Jake, Brian, and the team checked in from start to finish and I won't use any company but them for any future projects!

He also explained how the humidifier worked and made suggestions regarding settings. Great experience and we know who to call in the future for servicing. Thank you, LEA!!!
