Here's Some Required Knowledge For Today's HVAC Novices
In order to maintain a happy home, the last thing you want is for your HVAC system to go bad. Just thinking of it going bad on the hottest day of the year is enough to give your nightmares. It seems like this is when these systems decide to go bad. This can be prevented with good solid prevention tips that anyone can follow. Keep reading the article below.
When seeking a new contractor, ask loved ones for referrals. They'll often have already had someone in for similar work and will know who to trust and who to avoid. If your family hasn't used anyone, ask co-workers or other people you trust in your community for some references.
Clean the coils of your condenser fan each month. Turn off your power before doing any job like this. Leaves and debris can build up inside the unit and cause damage.
If you want to know more about efficiently heating or cooling your home, go online and download the ENERGY STAR Guide. It provides information for homeowners to learn more about how they can save money while still keeping their home comfortable all year round, so it is a worthy ready.
If you want to seriously extend the life of your HVAC system, as well as cut down your overall power bill, install ceiling fans in commonly used warm season rooms. Energy-star certified ceiling fans can sometimes cut your HVAC use in half. However, you won't physically notice a difference in temperature.
In order to cheaply cool your home, turn the temperature up. If you take a few showers a day or just drink a cold ice water, you'll find that you're saving a lot of money on your utility bills by keeping the thermostat a little higher than usual in your home.
Be sure you have the HVAC unit in your home checked about two times every year. The normally recommended time for HVAC system inspections is once before the peak cooling season when it gets hot and you'll be using your AC, and once before the peak heating season, during the cold months when you're likely to be using your heat. You should have it looked at even if no problems are occurring; there could still be a problem or potential problem.
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.
Installing a whole-house fan can either cool your home without the use of air conditioning or make your air conditioner more efficient. It blows out all of the hot air which collects in your attic, and this air flow draws in cool air from your basement and up into your home.

Make sure your HVAC is clear when working outside. You should try keeping any vegetation about two feet away from your outdoor units. Keep the get more info areas above it and on each side of it clear. Make sure you aim your grass clippings away from the unit when mowing. Keep leaves from getting inside your unit in the fall.
Inspect your HVAC unit quickly for blockage if you become away of any clicking sound. Often the issue is some sort of debris that's hitting the fans in the cooling system. Cleaning the debris will likely stop the noise. Check the fan and coil before you waste time contacting a professional.

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.
