How To Make HVAC Equipment Purchases Easier
There are some people who are fortunate enough to live in temperate climates where the weather is always perfect. For the rest of us, we need good HVAC systems that keep us cool in the summer and warm in the winter. For help finding such a system, read the following article.
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.
If you want to keep your air conditioning unit running efficiently, make sure you replace or clean the air filter once a month. Check the owner's manual on the a/c for instructions on how to clean the filter. Never run the unit when the filter is removed and let the filter dry before reinstallling it.
Look to your neighbors and family to get recommendations of good HVAC specialists. Likely there's someone you know who's already done a ton of research. Use this knowledge to help get you the best specialist you can. This can save you many hours of research time and money too.
When your contractor comes to fix your unit or install a new one, he should walk around your home and investigate what's going on with your current set-up. They should be looking for how much insulation you have, where your windows are and what quality they are and more.
Do not allow grass clippings to cover the outdoor unit of your HVAC system. Make certain the debris goes away from it. This also applies when you blow leaves, so be very careful near your exterior HVAC units when you move debris.
Consumers are usually advised to have their HVAC systems inspected twice a year. The best times to have the system checked is spring and fall, so you are sure everything is running at peak performance before the heating and cooling seasons. Even if you don't notice anything wrong, you can check it out to figure out what the potential issues are.
Cover your unit when you are mowing the lawn. Shoot grass the other way. The same goes for blowing leaves, so always be careful if you are moving debris near your HVAC devices.
When the weather cools down, turn your outdoor condenser off. This should be done when the temperature drops below 60u00c2u00baF to avoid damage. This helps the system last much longer and will have to be repaired less often.
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.
Finding the right HVAC unit is important, and a good one can give your entire home that nice comfortable feeling. If you need to make repairs or replace your unit, remember what you've just read. You'll quickly find that the info will help you make a much more easy decision next time with your HVAC unit.
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.
