We just purchased a home in Crystal Lake earlier this Spring, so when the AC started sporadically…read morequitting on us, we were crossing our fingers that we weren't going to have to spend thousands of dollars (and at least a few sweaty days in August) on a new AC unit. When the AC stopped working on a Saturday when the temps were in the 90s, I decided to call Wally's hoping they would be able to send someone out on Monday. To my pleasant surprise, Rick Novak was at my house in less than an hour. In addition to being able to quickly diagnose and fix the issue with the AC, he was a genuinely friendly guy that was a pleasure to deal with. He had the AC working in no time, and reassured us that the unit was in overall good shape and wasn't in danger of needing replaced in the near future. Thanks, Rick!!

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.

AMAZING SERVICE! DUSTIN IS AWESOME!!! Called a few HVAC…read moreplaces late in the day last week after our A/C unit wasn't blowing cold anymore. Dustin called me back and was able to schedule me in for the morning. Dustin was prompt, on time, and worked fast to troubleshoot the issue. The system was low on Freon so that's where we started. After filling up the system the A/C seemed to blow a little colder, but not much. Dustin was off to another appointment and wanted me to keep him updated once the system ran for a little while. The A/C wasn't getting any better so i made another call to Dustin who was able to come back the same day after his last appointment and take a look. Dustin worked very late into the day (on a weekend) and ultimately found that the A/C condenser in the furnace was completely blocked by lint and dirt, 100% blocked and not letting any air through. After cleaning it up, the A/C system is running better than it ever has. Ice cold A/C, keep the house at 75 in 95 degree heat, and the air is flowing strong out of the vents. Thank you Dustin! Not only is his service top notch, he couldnt be a nicer guy to talk to. He was very friendly and has a huge pride of ownership in his business, which is hard to find. Dustin and Absolute Comfort will be the ONLY call I ever make for all my HVAC needs.

I discovered Compass through a referral from another HVAC company. Think about that for a minute! Mike and his crew were excellent in every way, every step of the way. Usually after large purchases I tend to second guess if I could have done better or gotten a cheaper price...not this time. Mike's knowledge and expertise is obvious once you meet with him and that's all I needed to know I was in good hands. It was a no pressure sale also. Thanks Compass!

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.

Mid Oct 2024 they moved my 3ton A/C unit over and further from house making it easier for me to keep clean. It's taken me some time to write this review as I'm still recovering from surgery. 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.

No pressure at all. They provided multiple options and didn't pressure me when I wanted time to compare prices and products. After I chose Northern Continental, I received excellent work, at a competitive price, for better products. This shows how they service customers for both big and small needs. Different options for my replacement were offered at different price points, all reasonable and well explained. They took the time to answer questions, make a competitive quote, and completed a professional and clean installation on my timeline. I will continue to work with them for routine maintenance, and highly recommend their services. Another very happy local customer.

My Carrier a/c is making a really bad rattling noise. I called Carrier who referred me this…read morecompany and told me the unit has a 10 year enhanced warranty. I called and they came the next day to give me a diagnostic but were 45 minutes late. I had to reschedule another appointment because they were late. Five minutes of the diagnostic and $90.00 later the tech tells what he thought was wrong and that he would order the part. I said well what are your rates since the part is covered under warranty, he tells me it will be some administrative charges for the girls doing paperwork around $100.00 and 2 hours of labor for a 20 minute job. I understand labor charges but not 2 hours for a 20 minute job, and I don't understand the administrative fee of $100.00. so basically I'm paying for the part that is supposed to be under warranty. This will run about $400 to $450 for a part under warranty. Run, run, run from this company.
