These guys are amazing. After having other firms try to fix my antique (70-year-old) furnace, I…read morecalled Comfort Air. I should have called them six months earlier. It took them a day to fix the problem and all the problems the other contractors had created by not understanding how old furnaces work. Comfort Air was very professional, called when they said they would, delivered estimates well within reason and market value, and delivered on their promises on time the first time. If you have an old furnace, call these guys. As a testament to how well they did fixing my old furnace, when I upgrade to a brand-new system with duct work (which my house currently doesn't have), I'll be using Comfort Air.

I live in Wonder Lake and called with an AC problem mostly because they were so close. I think it…read morewas the owner Tom who came out and he did a great job. Nothing special per say but friendly, reasonable and while I was skeptical about the service agreement, It turned out to be a God send. Since that day, I have had multiple problems and every time they send somebody out the same day and always get it fixed. If you have the service agreement, you save a ton of money and trust me, if you live in the area, you will not find a better company. They don't make the prices up, they have listings of what things cost so it's the same price for everyone. This is my HVAC company for as long as I own my house and live in Wonder Lake.

They do provide the service requested and gave me a link to make an appointment. We'll see how things go in a couple of days. The repair man, Alex, was prompt and identified the problem - two problems, actually. He was able to get the dryer running again, better than it had been. Reasonable price

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.

This company is GREAT! After another company replaced my furnace and messed it up by miss matching…read morethe plenum size and furnace I got McHenry to do it. The other furnace was crap and only lasted a year before the blower failed (because of the pressure miss match caused by the plenum mismatch). They replaced the furnace with a good one, AND got it up off the floor like it SHOULD have been. In addition to correcting the plenum, they put a NEW and correct filter housing on it. That doesn't seem like a big thing except the prior company had some dummy install a filter housing with the screws facing IN to the slot where the filter sits making it a real pain to replace. So ya, I definitely recommend them.

Come Spring or Fall I'm planning to renew my maintenance contract. They come out twice a year to check HVAC and clean everything up. Again outstanding Customer Service every one works with you.
