Easy-to-understand HVAC Advice For Anyone New To It
The system you use to heat or cool your home is probably the largest influences on how much energy you use, and how much it costs. If your HVAC system needs updating, make sure the technician you hire is knowledgeable. The following article provides the information you need to hire the right professional.
If you must hire someone to help you out with your HVAC system, be sure to learn about all of the requirements your state has legislated regarding licencing and insurance. You need to be able to ask anyone you plan to hire if they meet these requirements before you hire them.
Before you hire an HVAC contractor, have some sort of idea of the work that needs to be done. It is going to be hard to get a price estimate on the phone if the current system isn't something they've seen. If you don't have any idea, they will have trouble giving you any sort of quote. Know the right information ahead of time.
Make sure the equipment you are buying is ENERGY STAR compliant. It may seem a small thing, but it isn't. Products that are ENERGY STAR compliant can save you a lot of money in energy costs over the year. It can be over $100 easily, sometimes a lot more.
If you have a window air conditioner without a timer, use a regular outlet timer to control when it is on or off. These are the same ones you use for holiday lights, so all you have to do is plug your air conditioner into the timer and set it to cool you during the day.
When the leaves start to fall, the HVAC equipment can be harmed. Make sure the unit's fan grill is cleaned frequently when the leaves begin to fall. The fan should have a clear path for air to come in. If it is blocked, your system will suffer.
An investment in a smart thermostat is truly going to save you money. You can program it to turn on and off at certain temperatures or times, allowing you to ensure that your air conditioner or heater isn't running when it doesn't need to be, saving you a ton.
The correct HVAC system should have sealed air ducts to minimize heating or cooling loss as air travels to different rooms. The heating or cooling requirements of different rooms in the home should be taken into consideration. There is no reason to increase energy usage by controlling the temperature in rooms that are used very little.
Change your air conditioner filter quarterly, or four times a year. This not only keeps the air coming into your home easier and cleaner to breathe, it takes a lot of stress off of your AC unit itself. You get to enjoy health, money savings and reduced energy use altogether at once.
When you buy a new air conditioning unit, don't let the salesperson talk you into too large of a unit. This will be a waste of money and won't efficiently cool your home. The longer a system runs, the more efficient it will be when it's running, so look for one which runs 15 to 30 minutes.
The HVAC system in your home is very important and must be properly serviced. Failure to do certain things will result in costly fixes and a miserable time for you. Don't be a victim of a faulty HVAC system, take what you learned here and use it to ensure that it runs smooth for a long time.
Ancient 'air-conditioning' cools building sustainably
How did buildings keep cool before the invention of air conditioning? As architects consider how to reduce the energy demands of new builds, some are turning to the past for simple, low-tech solutions.
At the height of summer, in the sweltering industrial suburbs of Jaipur, Rajasthan in north-west India, the Pearl Academy of Fashion remains 20 degrees cooler inside than out -- by drawing on Rajasthan's ancient architecture.
While the exterior appears very much in keeping with the trends of contemporary design, at the base of the building is a vast pool of water -- a cooling concept taken directly from the stepwell structures developed locally over 1,500 years ago to provide refuge from the desert heat.
Award-winning architect Manit Rastogi, who designed the academy, explains that baoli -- the Hindi word for stepwell -- are bodies of water encased by a descending set of steps.
"When water evaporates in heat, it immediately brings down the temperature of the space around it," he says.
While traditional stepwells often go many stories below ground level, Rastogi's go down just four meters. However, the effect is the same and -- like the ancient Mughal palaces before it -- the academy enjoys its own microclimate.

Rastogi wonders: "How did they think up something so elaborate and yet so simple in its basic philosophy?
"How do you begin to think that you can dig into the ground and use the earth as a heat sink, have access to water, put a pavilion into it so that its comfortable through the year? It takes a lot of technology for us to think up something that simple now."
But it's not just the stepwells that are involved in this process of "passive cooling" -- the general term applied to technologies or design features that cool buildings without power consumption.
The whole building is raised above the ground on pillars, creating an airy and shaded pavilion that is used as a recreation and exhibition space. Here, according to Rastogi, the walls are made from a heat-absorbing material that creates a "thermal bank" -- so the warmth is slowly released at night when the temperature drops.
Centuries ago, latticed screens or "jaali" filtered direct sunlight into the palaces. The effect was decorative and helped reduce the heat. Likewise at The Pearl Academy, a latticed concrete screen runs the length of the building and provides a cooling outer skin.
"We've been able to demonstrate that good green building is not only cheaper to run; it's not only more comfortable to live in -- it's also cheaper to build," says Rastogi.
The success of the academy's eco-design has had an impact. Regulations -- based on these passive cooling techniques -- were introduced last year for all new Indian government buildings.
