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.

Our technician quickly identified the issue and rather than try and sell us a new furnace, they made adjustments that they said would get us back in shape. It worked. This is the second time Ibbotson has been out and both times, Ibbotson addressed the issue for far less than we feared we'd have to pay. We're not kidding ourselves. We understand we are on borrowed time with this furnace but rather than exploit the situation we had a good, educational talk with our technician about ultimately replacing our system and given honest answers and solid options. I appreciate Ibbotson's integrity, professionalism and confidence. No high pressure sell. They know we'll be back when we're ready to take the next step.

I have to say, I'll probably go with JML when we do decide to replace it just off of the professionalism they demonstrated.

Tried to tune the furnace anyway to accommodate it, which was actually kind of fun to watch all the different ways it could be done. No other HVAC technician I've ever worked with before has done that. A/C maintenance went great too. First company I've ever hired that didn't try to sell me an entirely new unit just due to a faulty capacitor. Even gave me the model number of the capacitor to replace if I want to save money and do it myself (I'm reasonably handy so it's something I'd probably do). I'll be using them for as long as they give great service!
