So far two fantastic experiences. First one they spent a couple hours trying to diagnose my…read morefurnace acting up. Turns out it was my air filter being too restrictive. 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!

I read the Yelp reviews for Astera before I reached out to them, and the 5-star reviews are spot…read moreon! 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.

My furnace stopped working in the early morning of the first snow/cold snap and they were able to have a technician in my home that afternoon.

I also recommend Arlington Heights Heating very highly.

I have been their customer for over 15 years. They used to be excellent in providing services…read more Looks like the business has been sold and the new owners are not honest. In February, they told me that the cost to replace a board in the furnace was $850.00 in one of my rental properties . In the past if they quoted me a price of $850.00 the bill would be $850.00. This time in February billed me $1125.14 after quoting $850.00. When I asked to talk to the owner's daughter, the lady on the phone said that the owners daughter was on vacation and she would call me back in a week. I called again in March and asked to talk to Carrie, the owner's daughter. The same lady again said that Carrie is on vacation and she will call me back the following week. I still have not heard from Carrie. The crazy part is the February bill had a traveling charge! They have never charged me anything called traveling charge. On February 11th no one in the service industry had a traveling charge! Since I was a customer for over 15 years and Carrie and her family has provided excellent service, when I have been asking them to call me back for over 2 months, I am of the opinion that the business was sold and the new owners are not honorable. Their words don't mean a thing to them , examples: 1) Quoting me a price of $850 and charging me $1125.14 2) Telling me twice that Carrie or her father would call me back and have not. 3) Telling me Carrie is on vacation 3 times in l than two months!

The tech was courteous and explained what went wrong and how he fixed it. He also noted our unit is on its last legs but did not go into any hard sell.
