A commercial air conditioning unit is very different than any unit you have at home; a commercial unit will need to be stronger and more powerful to support the needs of a large commercial building, which means it often suffers more wear and tear. Renovations can also affect the commercial air conditioning system, even if those renovations are located on the other side of a very large commercial facility. Note a few answers to commonly asked questions about commercial air conditioning and then discuss your needs and concerns with a contractor if you still have questions.
1. Which is a better choice for new ductwork, steel, aluminum, or sheet metal?
Each material has their own advantage, but note that steel may be more prone to rusting or corrosion, while aluminum doesn't rust or corrode. However, aluminum is also more lightweight than steel so it may pull away from its connectors faster, as the force of air through the ducts puts pressure on those ducts. Sheet metal is a very popular choice because it's both lightweight and sturdy.
While considering all these factors, you might also note if you can find any of the materials from a recycler. If you want to make an eco-friendly choice for new ductwork, use material that has been salvaged or recycled so you cut down on the need for harvesting virgin materials.
2. Why is there debris all over the building when renovating just one part?
One thing to remember is that renovation involves a lot of dust and debris, even if contractors use vacuum bags and filters on their tools. If you turn on the air conditioning unit to your building, this will circulate the air across the entire building, no matter its overall size. This is why renovating on one end can mean dust and debris on the other end. It's better to leave the air conditioning unit off until work is completed or close and seal the vents in the part being renovated.
3. Why is there noise in a part of the building that isn't anywhere near the air conditioner?
It may not be the air conditioner itself that is creating this noise but the sound of the ductwork behind the walls and in the ceiling. Some ducts may have come away from connectors, or it may be that ducts in one part of the building were insulated whereas other ductwork was not. There may have also been damage to building materials such as drywall and wood, and these pieces are now banging or rubbing against the ductwork, causing noise.Share
