How Does a Heating, Ventilating and Air Conditioning System Work?

Central heating, ventilation, and air-conditioning systems (HVAC) are designed to maintain air quality and comfort in the home. The ventilation system initiates air flow so it can be ventilated, heated, and cooled. The air-conditioning, furnace and heat pump control air temperature and help filter the air so fewer pollutants are circulating throughout the home.

There are three major types of ventilation systems: exhaust, supply and balanced. Exhaust ventilation uses exhaust fans to pull air out of the home and reduce the air pressure inside so air flows in naturally from the outside. Supply ventilation does the opposite, pumping air into the building so the old, stale air leaks out. A balanced system uses both exhaust and supply fans so old air is pushed out, but fresh air can still come in.

Most central air-conditioning is composed of two units: a condenser and evaporator. The condenser is the outside unit, and the evaporator is in the inside unit. The condenser unit transforms a refrigerant, such as Freon, into a high pressure gas. As the gas flows through the tubing towards the inside unit, it looses heat and transforms back into a liquid, until it reaches the evaporator which transforms it into a low-pressure, low-temperature gas. As air circulates through the evaporator unit, the gas form of the refrigerant absorbs heat so cool air can be recirculated through the ventilation system. As the refrigerant heats up, it returns to the condenser unit to start the cycle again.

The furnace is connected to the ductwork, which usually has a heat exchange or fan to pull the heat generated by the furnace into the ventilation system so it can be circulated throughout the home. HVAC systems may also use a heat pump to supplement the furnace. A heat pump essentially works in reverse from the central air system. It draws heat from the outside air and moves it through the system to the evaporator which pumps the warm air into the ventilation system.

There are a number of problems that can occur with an HVAC system. If the duct work is not installed properly, the system can't maintain enough pressure to circulate the air. This will not only cause poor ventilation, but the furnace and air-conditioner will also need to work harder and will cost more money to run. Filters on the air-conditioner and furnace should be changed regularly. When the filter gets clogged with dirt, mold spores and other debris, these pollutants get circulated throughout the home and reduce overall air quality. Another common problem with an HVAC system is coolant leakage, which will cause the system to run inefficiently or not work at all. If you're having problems with your system, you can hire an HVAC contractor to make sure everything is installed correctly and make repairs if necessary.

How to Lay Concrete Roof Tiles

Concrete roof tiles are about three times as heavy as traditional asphalt tiles, but most houses can support their weight without any problems. Concrete roof tiles have some advantages over asphalt: They are incredibly sturdy and hold up better under extreme weather conditions; they can also be walked on without cracking, which makes it easy to put up Christmas lights or do roof maintenance. With properly installed concrete roof tiles, your roof can hold strong for more than 50 years.

Cover the roof with roof underlayment. Use asphalt-saturated felt, which is the traditional roofing underlayment, or synthetic underlayment, which is more expensive but longer-lasting. If you live in a wet or snowy climate, use a self-adhering underlayment, which has an ice and water barrier. To apply underlayment, start at the bottom of the roof. Unroll 5 to 6 feet of underlayment, line it up with the edge of the roof and then nail it into place with a nail gun. Repeat the process until you reach the end of the roof. The next row of underlayment will overlap the first row by 2 inches. Lay the entire roof this way. When you reach the peak of the roof, leave it uncovered and work from the eave up on the other side of the roof. When you reach the peak, lay one piece of underlayment over the peak so that it overlaps the underlay on both sides. Nail the underlayment into place.

Attach the tiles. If the tiles do not have anchor hardware on the back, use the nail gun to nail them into place. If they do have anchors, use battens, which are simply pieces of wood that lay horizontally on the roof and are spaced at equal intervals. Cut enough 1-by-4 battens to place one 10 inches up from the eave on both sides and then one batten every 6 inches after that. Attach the battens to the roof with 3-inch roofing nails. Specific instructions for attaching the anchor to the batten will be included in your tile package; the anchor will either screw into your batten or lock onto it in some other way.

Begin laying your tiles at the eave with 2 inches overhanging the bottom of your roof. Concrete roofing tiles have a side-by-side locking system to prevent water from getting through. Instructions on how to lock them will be included with the tiles but is as simple as sliding the side of one tile into the side of another.

Overlap each row by 6 inches. If you have placed your battens at 6-inch intervals, your tiles will already be set up to overlap that way. To make your nonanchored tiles overlap by 6 inches, move up the roof and make chalk lines every 6 inches. Line the top of your tiles up with these lines.

Top your roof with a metal ridge cap. Metal ridge caps can be purchased in sections or you can bend some yourself if you have extra sheet metal. The ridge cap should fit snugly against the roof and overlap the tiles below by at least 4 inches. Attach the ridge cap with a drill and 3-inch screws. Caulk between ridge cap pieces where they overlap to create a waterproof barrier.

How Are Carbon Credits Created?

To understand how carbon credits are created it is important to first understand the framework in which they exist and why emissions trading developed. Carbon credits are one tenet within a voluntary pledge made by over 180 countries and multitudes of corporations and individuals to reduce greenhouse gas (GHG) emissions.

Coal, natural gas and oil are fossil fuels, and burning these releases GHGs. These gasses include: carbon dioxide, methane, nitrous oxide and hydro-fluorocarbons. When GHGs are released into the environment they enhance the atmosphere’s ability to trap infrared energy, which may directly impact our climate.

The Intergovernmental Panel on Climate Change sounded the alarm that GHGs were reaching dangerous levels and should be moderated for the health, and ultimately the habitability, of our planet.

In response, a diplomatic core came together in Kyoto, Japan, in 1997 and determined that greenhouse gasses should be reduced to 6 to 8 percent below 1990 levels and developed a reduction plan known as the Kyoto Protocol.

The creators of the Kyoto Protocol recognized some of the pledging countries would meet and exceed their GHG reduction goals, while others would struggle. They built flexibility into the plan, allowing countries to create excess GHG reductions and sell them to countries not meeting goals. For trading purposes, one carbon credit is equal to one metric ton of GHG reductions.

These credits had to be measured, certified and brokered, and offset providers were developed to do just that. Hundreds of providers exist throughout the world, and they are regulated by the United Nations Framework Convention on Climate Change (UNFCCC) and the Financial Industry Regulating Authority (FINRA).

Buying carbon credits is easy. Anyone with a debit card who wants to reduce his carbon footprint may buy credits online.

Offset providers expanded membership beyond countries to include corporations and individuals. Like countries, these provider members make a pledge to GHG reduction and are eligible to create and sell carbon credits.

Several types of programs are eligible to receive carbon credits. Examples include: planting trees; disposing of waste organically; capturing and converting methane gasses produced by landfills, coal mines and agriculture.

The owner of the project submits it to an offset provider to determine eligibility. If eligible, the owner contracts with an accredited verifier. That person confirms and measures the GHG reduction, and submits a report to the offset provider and FINRA.

If approved, the provider issues carbon credits to the project owner. They are serialized documents which may be sold only once and then are canceled.

Carbon credits are big business. After the project owner receives carbon credits, she may sell them at the prevailing market rate, which ranges from $1 to $30. By the end of 2009, hundreds of billions of carbon credits had been issued and sold on the open market.

How to Repair the Radiant Heating Element in a Frigidaire Stove

The location of the Radiant Heaters element will depend on which model you own. Most Frigidaire ovens have the element in the base. The ranges and some have it at the back of the oven. Locate the element before you start work. Check it for damage. If it is cracked, order a new one. If it shows no sign of damage, the element is probably not the problem.

Unplug the oven from the wall.

Take out all the baking racks from inside the appliance. Remove the screws that hold the element in place. The screws will be attached to brackets on the sides of the element.

Tilt the element so you can see where the wires meet the element. Grip the wires with your pliers and remove them one at a time. They slide off. Take the element out of the oven and dispose of it.

Put the new element inside the oven. Attach the wires onto the new unit. Give them a squeeze to ensure they are tight. Replace the screws.

Put the baking racks back inside the oven, and turn the power on. Your Frigidaire appliance should now be working as normal.

How to Troubleshoot a Central Heating System

Once upon a time, heat came from baseboard or wall heaters that produced uneven heat. Things improved with contemporary homes that come with central heating systems. Central heating systems allow you to control the temperature through a thermostat on the wall. However, just like cars, sometimes central heating systems need maintenance or a repair.

Meet your Commercial heating system. If you have a heat pump or furnace, you likely have a ducted air system, which is the most common type of central heating. In a forced air duct system, a blower pushes warm air through the system and out the vents to warm rooms in your house. A gravity furnace doesn't use blowers; instead, convection currents move air throughout your home.

Change furnace filters annually or more frequently if you have pets or use air conditioning in the summertime. If you notice that the central heating system doesn't work as well as it once did, it could be because it's having trouble pushing warm air through a dirty filter.

Clear obstructions away from inside and outside vents for optimal air flow. Inside the house, that means furniture. Outside, look for leaves and debris blocking the outside vent. Remember to keep cold-air return vents, which are not connected to the ducts, unobstructed as well.

Check the pilot light if you have a natural gas heating system. You want to see a clear blue flame. A yellow or orange flame can mean a problem that requires a call for a repair from a service technician.

Consider contacting a central heating service technician to schedule a tune-up for your central heating system. Keeping your system properly maintained now could ward off a costly repair later.

How to Build Roof Trusses over a Flat Roof

Flat roofs are not really flat. All have some slight slope to allow water to drain. But all flat or very-low-slope roofs are subject to water problems. Heavy rain, snow and ice will not drain off them as quickly as from a pitched or sloped roof. Some flat-roof materials also are more prone to degeneration than pitched-roof shingles. Some homeowners also want or need more attic space than a flat roof provides. It is not uncommon to have a flat roof waterproofing replaced with a pitched roof, and that requires roof trusses.

Measure the roof with a tape measure and decide where the peak of the new roof should be and which sides should slope. Generally make the pitched roof run the direction of the longest dimension, but check the drainage on the sides so the roof does not dump water into a depression or some area that might impact the house foundation.

Decide on a pitch or slope for the roof and a style of truss. Pitch is expressed in inches of rise per foot, as in 5/12 (a common house roof pitch), which slopes up from the wall at 5 inches per foot. There are many styles of truss, depending on the width of the roof and the amount of space needed inside the truss. A basic type is called the fink, with two sloping rafters, a bottom beam or chord between them and diagonal braces in the center in a sort of W shape.

Start building trusses with a bottom chord, to go from wall to wall. Each end of the chord should be flush with the edge of the wall. Mark rafters at a 5/12 pitch. Put a framing square at the bottom of an end of a rafter board with the point at the bottom of the board, the 5-inch mark on the thin tongue and the 12-inch mark on the wide blade at the top of the board. Mark that angle, for a top or plumb cut, on the end of the board.

Use the "length of common rafter per foot of run" to determine the length from the plumb cut to the end of the bottom chord, where it will rest on the top of the wall. Multiply that differential by the rafter span, half the width of the roof, to calculate that bearing point. Add a foot to provide an overhang or eave and mark an end or tail cut, like the plumb cut but with the point of the square at the top of the board. Go back to the plumb cut and take off another 3/4 inch so two plumb cuts will have a gap for a ridge board.

Cut one pair of rafters with a circular saw at those angles and lay them on a flat surface with the bottom chord between them. Set the plumb cuts together with a 2-inch (actually 1 1/2 inches thick) spacer board between them to duplicate a ridge board, with the bottom chord level between the rafters. Mark the angle the rafters form across the bottom chord and cut it to fit. Remove the spacer and secure the peak and the two side bearing points with metal gussets, which have spikes on them. Drive the spikes in with a hammer to secure the gussets to both rafters, then add nails in all the nailing holes in the gusset plates. The gussets fit across the rafters just below the ridge board slot (some gussets are made with a ridge board slot).

Measure to the center of the bottom chord, directly under the peak, then measure half that distance on each side. Mark those quarter points and make four braces, two to fit from the peak to the quarter point on the bottom chord and two to go from that point to the rafter halfway between the bearing point and the peak. Cut those braces and fasten them with gussets. Turn the truss over and add gussets on all connections on the other side. The finished truss should have two slopes, a flat bottom and braces that make a W shape.

Remove the covering and decking from the old flat roof. Use a pry bar or roofing scraper to peel off any roof paper/gravel or membrane covering, then pry off the plywood or oriented strand board (OSB) decking. Remove the roof joists from wall to wall; the bottom chord of the truss will replace those. (Brace the walls temporarily if removing the joists weakens them). Use a level to make certain the wall tops are level so the bearing points of the trusses will be the same on both sides. Adjust the wall caps if needed to level them.

Build the number of trusses needed to span the roof from end to end, spaced 24 inches apart. Mark the walls for the trusses. Start at one end of the roof and mark 1 1/2 inches in for the first truss. Measure 23 1/4 inches in from the end of the wall to mark the outside edge of the second truss, then mark it 1 1/2 inches wide (use the 1 1/2-inch wide tongue of the framing square to mark that space). Mark truss points 24 inches apart to the other end of the roof. Use the blade of the square, which is 24 inches long. The last space may be slightly less than 24 inches

Lift the trusses to the roof, one at a time. Use at least three people for this -- one on each side of the roof with a 2-by-4 board with a notch on top to hold the truss and one (or preferably two) on the roof to set the truss upright and fasten it. Lift the truss upside down and let the roof workers set it upright. Use a level to get it vertically plumb and fasten it to the walls through the truss bearing point with framing nails and a hammer.

Raise other trusses to the opposite end of the roof. Set a ridge board in the tops of the trusses to connect them from end to end. Nail the trusses to the ridge board; use a level to keep the ridge board level the length of the roof. Remove any temporary braces. Add "hurricane clips," metal brackets that fasten the truss ends to the wall caps, on both sides of all trusses.
