Designing Heating and Cooling Systems in Large Buildings

Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.

Ready To Use The Fireplace In Your New Home? 3 Signs Your Chimney Should Be Repaired First

Nicole Jacobs

If you've recently moved into an older home, and you want to use the fireplace, the first thing you should do is schedule an inspection. You don't want to use your fireplace until you're sure it's in good condition and free from any hazards that could lead to problems for you and your family. While you're waiting for the inspection, you can do your own mini inspection to check for signs of damage that you'll need to be concerned about. Here are three signs that will point to problems with your fireplace.

1. Salt Marks on Your Bricks

If you've got a brick or natural stone chimney, take a look at the stonework. It's okay for it to be dirty since it's exposed to the elements. However, it shouldn't have salt marks on it. If the exterior of your brick or natural stone chimney has salt marks on it, you've probably got a water problem that will need ot be taken care of. When the brick and natural stone is securely attached, water can't get to your chimney. Unfortunately, when the brick and natural stone begin to lift away, water can get to the chimney, which will cause the salt markings to occur.

2. Particles of Flue Liner in the Fireplace

If you've got piles of flue liner tiles inside your fireplace, you've got a serious problem. The inside of your chimney is lined with flue tiles. The purpose of the tiles is to prevent chimney fires. Over time, the flue tiles can wear out and begin to decay. When that happens, they'll start to break away and fall into your fireplace. If your tiles are falling of the inside of the chimney, you're going to need extensive repairs before you can use your fireplace.

3. Cracks in the Fireplace Refractory Panels

If you haven't looked at the refractory panels in your fireplace yet, now's a good time to do that. The refractory panels are those cement panels that line the inside of your fireplace. The refractory panels are made of a special concrete formula that's designed to stop the excess heat from causing chimney fires. Under usual conditions, your refractory panels will last for many years. However, they do wear out over time. When they do, they can develop cracks, which will increase your risk of a house fire. If you've got cracks in the refractory panels, they'll need to be replaced before you can safely use your fireplace.
