"On estimate
Rich was prompt, friendly and professional. He was straight with me and honest. 

Another HVAC company told me I had to install pumps to each unit (I have 3) to help the flow of water (a total of $600). Rich explained to me that all that was needed were some "T" pvc for venting ($0.39 each) that he had on hand. Since it was a quick task, he put them in for free.

He gave me a price that was $1,200 LESS than another estimate.

On the work
He called the day before letting me know the weather looked bad on the day of the install - depending on the weather, he might have to do it the following day. I really appreciated that notice given I have tenants. It was very professional.

When the weather was better, he showed up- as promised - and he kept in communication with me.

A few hours after he left it wasn't cooling the apt. We chatted by text even though it was late. He came out the next day without complaint and fixed the problem. All the while keeping me informed.

Overall
Although the install was a bit bumpy, he never complained, was considerate, easy to work with and treated me very well.

He has earned a customer for life.

"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."

Heating and Air Conditioning FAQs, answered by experts

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
