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.

They did an absolutely fantastic job installing a new furnace and a/c unit in my house. They far exceeded my expectations and did a more than complete job, replacing everything inside and outside including new electrical, sheet metal, pad , humidifier, electrostatic filter, flue, thermostat and even provided a new condensate pump. I did not expect all that I got and could not ask for more! All this and completed the same day we made the agreement!

Communication lapses do happen,that would have taken 1 star off the review if that was it. But quoting 3x the price for as far as I can see a very similar unit is still mind boggling. My quoting agent sold the known higher costs in general as the value of the 100% satisfaction guarantee, but from what I've read in other reviews, people are having a hard time getting covered repairs or replacements done at all. Again the person contacting me to try to resolve my concerns seemed very sincere, but I still would NOT consider using Precision Today as my HVAC hardware or service provider. Precision Today purchased Miller's Area Heating, which was highly recommended by two different friends. I requested a quote from Precision re: a replacement boiler for the radiant baseboard system in my house. After a good phone response the first day, I had no confirmation to set up the actual quote visit. After a mid-day call to them, they gave me a 3;30-5:00 window that day. At 5:55 I got a call saying the agent was on my doorstep. After reviewing my system, I was quoted $22,000, AFTER DISCOUNTS. My research indicated it should be about $4.000- $9,000 for a new boiler and install. I then read many Yelp reviews and saw reports similar to my experience; bad communication and very very high quotes and charges for relatively simple repairs/replacements. Also bad reports on following through with their lofty guarantees, which I mention because those are the reported reasoning behind their admittedly high prices. Very unfortunate.

This morning,…read morewhile leaving Grayslake, I was cut off in traffic after making a left-hand turn onto rte 120 from hwy 45. As I was getting up to full speed + at least 10pmh over the speed limit on this stretch of road, I was passed by a van doing at least 70 in a 35-40, then the van slammed on the brakes so that I would have to as well and all of my belongings flew into the front seat; I admit, I wasn't on my best behavior either as I sped up when I noticed what he was obviously & illegally trying to do. This act was followed by continued bullying as we both drove west on 120, with the right lane being closed a short distance ahead due to road construction. The van (picture attached) then drove about 45, riding shotgun next to a construction vehicle, knowing that this vehicle would have to move to the right; he was hoping I would be cut off a second time. When I called the number on the van to report the driver, he laughed at me and called me a "F**king C**t" (when I came into full view of him as he merged onto 94E he was on older gentleman with gray hair & a moustache so I can only assume he was Tom Sr.). I would NOT want this person in my home--NOT ever. He doesn't respect or have regard for others, esp. women or Veterans (I am both--my car is clearly marked with both). We use Advantage Heating & Cooling for all our service needs, and they have always been extremely professional. Maybe that's why they have quite a few 1-star reviews on Google citing erratic driving & rudeness.

They said they could come out on Tuesday for service. They asked morning or afternoon. I said afternoon please because I have a doctors appointment in the morning. She said it'll be between one and five. At 4:30 PM on Tuesday. I hadn't received a call so I called to check on the status of the service. I was told at that time that I didn't have an actual appointment, I was on standby. Standby? What the heck is standby? Standby means that if they have a cancellation, they would work through their standby list. After some discussion I found out I was 10th on the list. That probably means I would have Service sometime in July or August. I can't believe that they run a company that wouldn't tell me about standby when I booked the appointment. Why would they ask morning or afternoon if they weren't even sure whether they were going to be here. I am a very dissatisfied customer and found another heating and air conditioning service that will be out here tomorrow.
