"When my desk top computer failed I called Mr Ferrell. His response time was excellent; arriving at my home the same day I called.
He called me back that evening to update me on what he found. He replaced the power supply and did a virus scan and returned the computer to my home within 48 hours. I found him to be computer savy and very friendly. If we have computer issues in the future I will contact Mr Ferrell.

"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."

My mother's air conditioning unit was about 20 years old and for the past 2 - 3 summers, she had had problems with the air going out. She used a warranty company but this time they wouldn't help saying she had had someone outside of the company work on her unit (which she hadn't). After many calls and conversations, she realized they would not help. She called me (my mother lives in St. Louis, but I live out of state) asking for assistance. I went online and called several companies, it was close to the holiday weekend and no one wanted to come out and to give a quote until the following week - after the 4th of July! My last call was to Manson's Heating & Cooling. They answered the call promptly - I didn't have to go through a series of prompts and button pushing to speak with someone, and they agreed to come out that same day. When the technician arrived (Kim), he checked everything out and stated her unit was basically worn out and did need to be replaced (which is what the two companies through the warranty company said also). At this point her air had been out for about two weeks with the temperatures in the 90's and she was desperate. He quoted her a very reasonable price, and she called to have me speak with the technician. He was very straight forward and explained to me what was going on with her unit, and why it needed to be replaced. I explained that I would be paying for the unit to be replaced, but that I lived out of state and could not get the funds to my mother's account until that Thursday or Friday. We were able to work out a deal over the phone that was comfortable for each of us and God Bless him, he put her unit in the next day!

I called her back that Tuesday and she was so happy to have them there putting in her new unit. She stated they were so nice and respectful. They arrived around 8 am that morning and everything was completed by early afternoon. She has had no further problems with her air and hopefully it will remain that way long into the future. But if something does happen, our first call will be to Manson's Heating & Cooling!

"Technician came to the house and analyzed the problem. It was determined that the cost of repair was over the allowable Choice Home Warranty limit and it should be replaced. Choice Home Warranty issued their replacement cost. This cost was unacceptable and I challenged their figure. After some negotiation I was offered an increased settlement amount. I still balked at their offer but I was told to take it or repair my old microwave. I finally accepted their amount, even though it is still well below what it will cost me to replace the unit. I might add that the existing microwave has the convection feature and I want to replace with same features. The cost that I will receive also does not include any removal, disposal or installation costs. At this time I am debating whether I will continue with Choice Home Warranty or consider other options."

"My experience with the Spengler Company was great.  Colby arrived at my house on time and then proceeded to perform the cleaning of my air conditioning unit.  He found that our refrigerant was low so he filled that up.  And he also changed our air filter for FREE!  He then gave me six options to replace the water heater in our home.  It was over 20 years old and had been leaking on the floor.  We selected the second option and he called it in and our water heater was changed out the same day!  WOW.  What service!  We couldn't be happier.

FAQs for central humidifier installation and replacement projects in Alton, IL

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.
