After a late night message, Erin called me first thing the next morning and they were on my doorstep before 10a. They diagnosed the problem right quick. Greg has been at this for a bit and clearly knows his stuff. Over the next few days they worked hard to find us a backordered part (getting lucky on EXACTLY the right day) and had us up and running again as soon as humanly possible. Price was right, too. Next time I have a problem, I will without a doubt be calling them again.

The technician (Pat) was to arrive between 12 - 5pm. I called the office and verified the time. I was told they would be arriving after 2pm. At 4:45pm, I had to call the office again to verify that my appointment was still on. Finally, at 4:50pm I received a call from Pat. He advised he was at another job site and that he would be late and couldn't verify his estimated arrival time. I completely understand that things happen. However, it is unacceptable that someone with the company or Pat himself could have not called to advised that there was an issue with my appointment. If they can't make a simple appointment on time or make a phone call, will they be available when you really need them?

I contacted Lake County Air Conditioning after having another company come out and look at my…read moresystem since my Nest Thermostats stopped working and I could not turn on the A/C. The company that came out wanted to charge me $1600 to replace the zone control board and change the Nest thermostats back to regular thermostats. He stated the Nest thermostats were not designed to work with a zone system. Being highly skeptical, since he only looked at the room where the zone control board was and he did not put a meter to the board, I told them I would think about it. After calling Nest and the manufacturer of my control board it was determined that the Nest thermostats do work with a zone system and the manufacturer of the zone board walked me through some troubleshooting techniques that I could do however, since I did not have a volt meter, I would have to call someone. I contacted Mike at Lake County and explained my problem to him. He immediately knew what my problem could be in that he would have to troubleshoot the system from the control board back. He said it could be something as simple as a clogged line that shut the system down. Mike came out and check the power to the control board and there was no power so it was not the control board. He then traced it back to the transformer which was getting power and then further traced the problem back to the float valve which was tripped because of water in the line. He drained the line and put the float valve back on and checked the zone control board and there was again power to the board as the lights were on the board. Problem Solved!!!!! The cost for the repair: $90.00 plus a small trip charge. What a big difference in price and quality of work. Mike was extremely honest and did not try and sell me on equipment and parts I did not need. He used basic troubleshooting skills to diagnose the problem and resolve the problem. He has earned my business from this day forward. My impression of Mike is that he is very conscious and knowledable about his craft and believes in treating his customers in and honest and fair manner. He will not upsell you just for the sake of making an extra buck or make the job seem bigger than what it is. I am extremely happy and pleased that I was able to connect with Mike at Lake County Air Condition. If you contact him, I'm sure you will be pleased too and become a customer.

We usually get bi-annual maintenance; however, this year was a big letdown. I scheduled with the office for service on Thursday, April 2, 2026. I paid in advance for both services, but when I asked to schedule the 2nd service, I was told that she did not want to pull up that calendar yet. Any way my April 2nd appt. was to be between 12PM - 2PM. When it came to 12PM and past 2PM, I called to inquire when we may expect out mechanic. At that time, I was informed that the mechanic was probably not going to make it out that day!!! I was told that one employee called in sick, the other was working on a new install and the third was too busy. Mind you no one bothered to contact me earlier to let me know there was going a delay, much less a no show. when asked if I wanted to reschedule, I said yes, thinking it would be the next day or at the least the next week. She offered me an appointment for the end of the month, not acceptable!!! Poor service, communication and a lack of trying to accommodate a long-time loyal customer cost this company my business!!! with the attitudes I encountered, I don't see this company lasting very much longer. This is sad to say, because St. Louis has been here as long as I can remember. I used them for different business' where I worked and always enjoyed my interactions with the "old" staff.

I am writing to formally express my serious concern and disappointment regarding the HVAC system…read moreinstalled at my property by Roosters. At the time of purchase and installation, I was verbally assured that I would be receiving a Tier 1 Carrier HVAC system. Based on that representation, I agreed to proceed and paid the full amount requested. I relied entirely on the verbal description provided, as no written documentation specifying brand or model tier was given to me at the time of sale. It has now come to my attention--while reviewing documentation during tax preparation nearly a year later--that the unit installed is a Bryant system, not a Tier 1 Carrier unit as promised. While I understand that Bryant is manufactured by Carrier, it is widely recognized in the industry as a Tier 2 product line. This is not what was represented to me when I made my purchasing decision. Had I been clearly informed that the installed unit would be Bryant rather than a Tier 1 Carrier system, I would have reconsidered the purchase, negotiated the price accordingly, or explored other contractors. I feel misled and taken advantage of, especially given the significant financial investment involved. This situation has caused me to question the transparency and integrity of the sales process. As a customer, I expect clear, accurate, and documented representations when making major home improvement decisions. Instead, I received only a total amount due and a verbal description that did not match the product ultimately installed.
