"When my HVAC unit went out I called A n 1 at 12:30am, as I have gotten home from work not too long ago. He answer and said he be right there. He came through check it all out and let us know exactly what needed to be done. He quote us too on the price if we decide to stick with him. Since he is a smaller personally owned company he didn't have financial options. So we had to think if over. Anyways I offer to give him some cash for coming out here so late and he kindly refuse, which was very kind of him. Even though it was already 2am by the time he was done checking it all out. After a few calls to other companies we realize we rather pay a hard working, honest man and help smaller local business. Also his price was unbeatable and the quote he quoted us was what we pay no hidden cost or anything. Needless to say we were highly satisfy with his work and his honesty. He was upfront with what was needed and didn't not try to sell us on anything else. Highly recommend his service! And the price was very reasonable!!!"

"On April 30, 2025 we utilized the services of Duct Dusters, Springfield, IL to clean our ducts prior to an installation of a new HVAC system. We selected Duct Dusters because they are BBB Accredited, had a 5-Star rating, great reviews, & the owner, Jeff explained their cleaning processes in great detail. Our technicians, Max & Cody arrived on time; were friendly & professional; wore booties over their shoes; showed us before-during-after pictures of each duct; and left the premises tidy & free of debris. They deserve our 5-star rating."

"Dave contacted me by phone in response to my request for a quote. He told me what the cost would be, and that is what I was charged when the job was completed. The price was very reasonable. He was professional, courteous, and showed up on time. He did a great job getting out duct work cleaned out and communicated with me at the end about what he found. I'd recommend this company and will use their services again."

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

Heating and Air Conditioning FAQs, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.
