"There is no other way to describe my experience except outstanding and even enjoyable! Friendly honest realistic and so dang fast! I even threw another project at them as they were walking in the door. that was no problem they completed both projects I wanna say within two hours after leaving to go get parts. I never once felt intimidated or afraid that I was being cheated. There was something very reassuring; when your handyman tells you, that there is very little in my home they can’t fix. It is only fitting that Air Duct Man appears at the top of my contact list! Hire these guys! You will wind up feeling as good as I do!"

"Sam did a major overhaul on an outbuilding at our new shop in Union, MO to turn it into and office. New roof, flooring, repaired lots of water damage, paint, and cleanup. The work was done in a timely manner. Pricing was reasonable. They stayed within budget and let me add on a couple things. 😁"

Heating and Air Conditioning questions, answered by experts

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
