    We had a great experience with Chill Heating and Cooling. First off, I had a total of four…read moredifferent companies give me a quote to replace our existing Furnace & A/C units. Chill was the second to arrive and give us an estimate. At first glance when comparing the numbers they gave me to that of the first company, they seemed way off and too cheap to be real. After getting more quotes, Chill remained the lowest price; however, the cost for some of the other companies came in somewhat close. Upon closer review of the contracts, the type of units offered by Chill were much better. A clear difference and made the price look even better! So we signed up and set our appointment up for the next week. We had to move the date since we felt the timing was terrible (expecting 90° weather when the following week was going to be 60°). They moved the appt with ease, even setting it for the following Monday -- on Memorial Day! This was something they offered and I jumped on it, since I was planning to work from home anyway that day. The day of the install went as expected. No issues arose; although, for the guys in the attic I think they would say they had to make some unplanned adjustments -- no complaints to myself or family. All three workers were extremely kind and respectful. They arrived at 9:20 AM and were out before 6:30 PM. Before starting work, they laid down tarps along the hallway (where the entrance to the attic is). They placed all of the old furnace/AC equipment out in front of the house, but cleaned it all up and packed it into their vehicles. They swept up most all of the leftover debris that fell from the attic space and gathered all of their tools. Upon exiting, one of the installers walked me through how to setup the Google Nest Thermostat. He was very patient and waited to ensure the system was fully functional before leaving (used a thermostat gun to read the temperature on one of the vents).

    Great service from Chill Heating and Air. The technicians arrived on time, diagnosed the issue…read morequickly, and provided recommendations on how to proceed. We ended up with a new HVAC install as our previous unit was at the end of its life. They were professional, clean, and honest about what needed to be done. Will use again.

    My AC was not turning on. I had already tried several troubleshooting steps myself but could not…read morefigure out the problem. I saw the great reviews for AIS and noticed a $58 service call special advertised on Yelp, so I reached out. Making an appointment was incredibly easy. Brenham arrived in just a few hours. He was pleasant to work with and clearly knew his stuff. He quickly diagnosed the issue and fixed it; it turned out to be a disconnected wire, so it was a pretty simple fix. While he was there, he also looked at another issue I was having with my heater short-cycling. It turned out the motherboard needed to be replaced, and he luckily had one with him. The price was on the higher side for a relatively simple swap, but I understand I am paying for his expertise, and since he fixed my AC on the spot, it seemed fair. He offered various other upgrades and maintenance plans, but all of that felt unnecessary for a 34-year-old system that is on borrowed time, so I declined. I would definitely use this company again and was very satisfied with the service.

    My furnace fan/blower would not turn on and with being two days away from mid-to-high 90 degree…read moreweather arriving, I was dreading how to live through the heat without air conditioning. I called around and AIS came to the rescue. They were able to send a technician, Brenham, out the same day! My window was between noon and 3pm. I got a text from the office at 12:30 that the technician would arrive close to 2:30. Even though that arrival was within the window they had already communicated, they still thoughtfully reached out to give me a more precise time. This was much appreciated as it allowed me to run out and do a couple of errands before the technician arrived. Brenham texted me about 20 min before his arrival saying he was on the way. He arrived right on time and was very respectful and had a nice, easy going demeanor. He got right to work troubleshooting the furnace, explaining to me how he was approaching the task, which I appreciated. I even learned a couple of things about furnaces! The issue ended up being the furnace's mother board and the "universal" board he had was not compatible. I feared this meant he would have to order one and it would be more days without AC. Brenham said he would check his van to see what he had and thankfully had the exact board for my furnace. He replaced the board and the furnace blower turned on! Even though my issues was resolved, he took the extra time to check on my outdoor AC unit and did some diagnostics including checking the refrigerant levels. It was a nice "extra comfort" to know the AC unit checked out fine. I was in a jam and AIS came through for me. Brenham was extremely knowledgeable and did great work. HIGHLY recommend AIS for all your HVAC needs.

The scheduling was effortless, with clear and consistent communication via email and text every step of the way. Messages like scheduling, notifying they were on their way, and text reminders for the appointment. Next level professionals. On installation day, Cody and his partner were professional and efficient. They promptly set up the work area, protected the surroundings, wore shoe covers, and clearly explained where the inlet would be placed to ensure we were happy with the aesthetic. They unpacked everything and went straight to work By the time I was done with chores in the backyard, they finished the job super duper fast, and when I returned inside, the fan was fully installed and working perfectly, exactly as I wanted. The fan quality is excellent with a brushless motor. Such a good value for efficiency and long life. The airflow throughout the house is awesome, cooling every room with fresh air while saving on electricity--a great value. I highly recommend QC Guys for their outstanding service and quality. True professionals.

Juan came with the sales pitch (i:e: if you agree to go with us now, we'll give you a discount...but only if you decide RIGHT now). I had to sit through a binder presentation and he told me I needed a new furnace to go with my air conditioner unit because the A/C condenser and furnace have to pair up for operational purposes and they won't replace one unit only if they are both more than 8 yrs old. He showed me some scary pictures of his furnace "inspection" and said my furnace was a fire risk, had evidence of decomposition and potential CO exposure and in the "interest of safety", he recommended a full system upgrade. The pictures were legit bad and concerning, but the funny thing is, the pictures he showed me were not the inside of my furnace. I had 4 other local vendors come after him and all of them showed me photos of inside my unit. Guess what? Their pics all matched each others and none matched Juan's pictures. Weird right? The other 4 local vendors inspected my furnace and all of them noticed the refurb of all the major components I had done 5 years ago. All said that no furnace replacement was indicated and my furnace was in great shape with many high functioning years left. Weird right? I intentionally never offered that info up to any vendor before the inspection as a secret test to see who would be an honest tradesman and who would not. See a pattern here folks? Juan's quotes came in at $17,500 for an electrical system (a/c and furnace) and $18,046 for a gas system (a/c and furnace), because you know...can't just replace the AC unit in his world. All other vendors (who have higher/better reviews on Yelp btw) came in between $8-10k for a new a/c unit. Again, all said no need for a new furnace. So, i'm counting my lucky stars I wasn't duped. Going with someone else and getting my new A/C unit installed tommorow
