"They were clean and considerate and understood our health concerns. They removed all infected material and mold, fogged the room for airborne spores, and fixed the outside gutter problem which caused the mold. You should hire them."

I am a jack of trades independent contractor/ handyman with 10+ years experience. I am not a licensed plumber, licensed electrician, or licensed roofer. With that said it's easier to just tell you the things that I don't do. I do not do drain work, I do not replace electrical lines or panel boxes, I do not replace plumbing lines which includes water and gas, and I do not replace roofs. Aside from that I can do everything else, and have the tools to do so.

"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."

Heating and Air Conditioning questions, answered by experts

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
