Great Tips About Hvac That Anyone Can Use
Learning about HVAC may seem daunting, but if you have the right information, it doesn't have to be a difficult task. This article can be a big help to those that are looking to familiarize yourself with the subject. Check out this article and learn more.
Before you hire anyone to do any work on your HVAC, be sure to get a written estimate which has itemized costs listed on it. This will ensure that comparing one contractor to another will be simple as you can see what one offers that another doesn't, or what price they're charging for the same items.
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.
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 the spring comes and the days begin to warm up, call in a pro to give your HVAC a once over. This will ensure that your air conditioner works as expected all summer long, stopping you from sweating it out when you least expect the system to fail.
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.
Keep your condensers free of nearby obstructions. Keep plants, fencing, even bushes back and away from the unit. Two feet is a good minimum distance it should have from anything, including walls, but the more space you give it to breathe, the better it will work and the less likely it will be to fail.
If your evaporator coil, found inside your home, becomes dirty, your unit will lose efficiency. Just pop off the front panel of the furnace and check to see that the coil is dry. Using a brush attachment on a vacuum, gently clean the coil of any dust or other debris.
If you are looking to save money with your HVAC system, consider turning down the air conditioner in the summer and turning the heat down in the winter. Putting on a sweater on a cold day can save you a ton of money on your utility bill, as can enjoying a cold drink instead of heavy air conditioning use.
If you are going to use the Internet as a source for good HVAC contractors, you need to be very careful. You never know who is behind the glowing reviews that are more info posted all over the Web. There is a chance that the contractor is posting their own reviews or paying others to do so.
After reading the above article, you should now know that your HVAC system should be properly maintained. If you let it go, you will only end up with major problems in the future. The last thing you want is to come home one day and realize you have no air coming through your vents. To prevent this from happening, study the tips that you just read to ensure the HVAC in your home lasts a very 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.
