"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."

"Used Angie to find a local (handyman) and within minutes was contacted by Tim. He arrived at my house within hours and was able to find the issue with a light fixture, that I could not resolve. Very satisfied with the work and Tim was great to work with. Will be recommending him to any neighbors that need help."

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 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

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.
