"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"Fantastic!! We had never had our ducts cleaned or sanitized. To my knowledge it was the first time ever and our house is 24yrs old. I can breathe again and the dust that is normally there 3 days after cleaning is gone. Nothing like before! The man explained all of my options clearly and did an amazing job. It was alot of work since we had just about everything done except the dryer vent because it is brand new. Kevin was on his own for the day as his helper was sick and he still had a good attitude and did a spectacular job. Didn't leave a mess either and cleaned up great before he was finished!"

"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."

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"Scott is a great guy and skilled technician. I attempted to repair my ac unit myself. I called him on Saturday morning because I needed a fan puller to get the old one off and Scott brilliantly called a place that offered one and allowed me to pick it up and use it then buy it after the job was complete! How awesome is that? In the process of replacing the condenser fan I must’ve displaced a wire or something and informed Scott. Who then called me and came out on his afternoon off to fix the issue! Do yourself a favor and call Scott the first time. He does a great job and won’t jerk you around like some of his competitors."

FAQs for central humidifier installation and replacement projects in Herculaneum, MO

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
