"Cory and Joe were fantastic. The installations went without a hitch. The overall cost was lower than three other quotes I had received for the job. At the beginning of the A/C install I noticed the water heater was leaking, and they were able to replace it the next day. I will definitely use them again."

"Sooo....first, Jim is a very nice guy.  However, Jim now works in Nashville during the week and is only home to the Huntsville area on the weekends.
My first impression of him was that he was awesome.  My computer system had crashed because I pulled the plug during a thunder storm before the computer fully shut down which resulted in the computer hanging up.  Jim took my call while in Tennessee and suggested how to fix the system.  For this I am very grateful.

What happened next was I had him come and check my computer to make sure everything was working properly.  He came to my house and spent an hour tweaking it (basically running various checks on the system), for which I paid him $50.  He suggested that my laptop would work much better if I had Windows 7 and increased my RAM up to 4 GB.  He said he could install it for me for (including the RAM) for about $160.  We met the following weekend for the handoff and he loaded Window 7.  When I received the call it was ready, the bill was $227.50.  I was surprised that is was $70 more than quoted, but paid it anyways.  When I asked about the RAM, he mentioned he did not upgrade the RAM and this would be another $60.  I was a little discouraged at that point since I felt like I was being taken advantage of, but the guy is relatively nice, so I said to go ahead and order the RAM.  He did so and the following weekend was supposed to install it.  Due to some personal things in his life, he wasn't able to install it, so I picked it up since I had to go out of town and could use the IT guy at my new location to install it for me.  When we went to install the RAM, the system wouldn't let us do it since my particular type of laptop can only take 2GB of RAM max.  If Jim had gone to the crucial.com website (where he bought my RAM) and entered my computer system on it, it would have told him the max amount of RAM that could be installed on that unit.  He did not do that.  He is supposed to refund my $60 this next weekend.

I think if Jim wasn't burning the candle at both ends by having a job in Tennessee during the week and trying to run this business on the weekends, it would've been a better experience.  Perhaps taking a few extra minutes to SLOW DOWN and write out an estimate of everything he would need for the job including the prices would ensure people know up front how much the repair would/should cost so they can budget accordingly.  I think if he had taken that approach, it might've been a better experience.  So now I am stuck with a laptop that runs slower because Windows 7 uses more memory and a laptop that can't be upgraded to more RAM.  Basically, the last step which cost me almost $300 was not necessary.  If you need something simple done like coming back from a system crash, he would be okay to use.  Otherwise, for the bigger jobs, I recommend he provide a written estimate with the items he plans to do.

UPDATE:  After posting this review, I received a number of text messages from Jim commenting on the bad review.  I understand he is upset, but harassing someone about a review is not a good way to go.  My review was honest and not meant to be mean, but to let those that use Angie's list get what they pay for...an honest review of someone's experience."

"One afternoon when leaving our local Costco we noticed a booth advertising Lennox air conditioning for the home. After the last 4 years of record summer heat, we decided to begin the process of investigating this solution. The appointment for the estimate went well with the entire process carefully explained and all of our questions answered. So, we decided to pull the trigger and buy the system. To our delight, company had an opening for the installation a week ahead of the original date and things only got better from there. On the day of the install, Isaac and his crew arrived on time and enforce. At one point there were 6 people and three trucks, all tightly coordinated. Everyone was courteous, professional, and fast. In a little over 6 hours the system was completely installed and thoroughly cleaned up. Overall, we could not be happier with this decision and highly recommend this company for anyone considering whole house A/C. Replacing 13 fans and 2 portable air conditioners is an elegant solution."
