The Best Advice For Buying HVAC Equipment
If your furnace stops working on a cold winter's day, you need to have it repaired right away. The same is true if your air conditioner gives out during a heat wave. In some cases, you may need a whole new HVAC system. This article has some useful information for dealing with these issues.
Although most people are thinking of their heating systems during the winter months, air conditioning is also important. When installing a new furnace or heating system, make sure the air ducts are also set up to work with your air condition system. Using the ducts for both heating and cooling is the most economical choice.
Understand what you want before talking to a contractor. Providing you with an accurate estimate over the telephone may be difficult to impossible is they can't see the system you have. In addition, you need to be able to tell the contractor what you have already tried. Understand this information beforehand.
Clean your permanent air filters or replace disposable ones every single month. If you have the choice, an electrostatic is the best option on the market today. Be sure to turn off your unit before you change the filter as it should never be run without a filter in place.
When you're trying to cut your grass, don't cover a unit outside with the clippings. Direct the clippings away from the equipment. Do the same when blowing snow or leaves.
Ask for references and be sure to call them as well. You are dealing with a high ticket item here, so you'll want to do your due diligence to make sure you are getting the best for your money. Ask for references, but don't stop there. Call each reference to check. A lot of people don't take that important last step.
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.

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.
Ask for helpful information when you are looking for a HVAC contractor. People usually love to boast read more about the wonderful work they have had done, so you should be given great leads to follow. This is also a great way to get names of companies that should be avoided.
The preceding information should have been easy to follow. If you use the tips above, it's pretty easy to get into HVAC. Use the tips and you might be able to make money soon.
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.
