Here's Some Required Knowledge For Today's HVAC Novices
It is important to educate yourself on your HVAC system. You'll find some great information in the following article that will give you the basics. Take some time to read carefully and you will do just fine.
Know what you need before you hire a contractor. It's hard to get an estimate since they haven't look at your system. It can be harder if you don't know what's wrong. Know the right information ahead of time.
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.
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.
Clean your fan and coils when the weather begins to warm. Shut off power before working or cleaning your system. Also, be sure to clear leaves and debris from your condenser unit.
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.
In the winter, wearing layers can save you a ton of money on your utility bill. If you can install a digital thermostat that makes the house cooler when you're asleep and warmer just before you get up, you can see significant savings on your next bill when it arrives.
There are sizing calculators available to determine the proper sized system for your home. If the unit is too large, it won't cool more than a smaller unit, just less efficiently. Check your manual to learn what it is rated by the manufacturer if you want accurate information.
Do you want to make sure your HVAC unit works for you like it should? It is important to have your unit maintained on a regular basis. Any reputable technician will know exactly what you mean if you call them and ask for a maintenance service on your system.
If you have a window air conditioner, be sure to check and see if it has an Energy Saver button. If so, use it! This turns off the fan when the unit isn't actually cooling the air, which can save you as much as 30 kwh over the period of a month!
You should be sure to change the air filter of your HVAC system once every six months. Neglecting to do so can cause dust particles to clog the air ducts. In turn, your system will not work properly and you will find your bills going up. It's worth spending the time to clean the filters.
To run an efficient HVAC, you must ensure your house is fully insulated. First, check into your attic to find out if you have the right kind of insulation and enough of it. If not, investing in getting that up to grade is better than installing a strong HVAC system!
Every contractor out there is responsible for setting up their own fees, so get several quotes before hiring anyone. You can save a lot of cash simply by doing your homework. In an ideal situation, you can estimate a reasonable rate by getting quotes from up to a half-dozen individual contractors or check here businesses.
Make sure you wipe up any water that is close to the air intake of the vents of your HVAC system. Clean up any water that is standing around because water can cause mold to easily expand. Some water buildup is normal but if you're picking up water more than once every six months you might have a problem, so contact a HVAC technician.
A great way to reduce the stress on your HVAC unit is to install ceiling fans in your home. During the summer, you can have them blow downward to cool the air and make your home feel more comfortable. In the winter you can reverse the direction and circulate warm air trapped at the ceiling.
If your home gets hot in the summer and you'd like to use your air conditioner less often, consider a metal roof. It reflects the heat right back up into the sky, allowing your home to gain less heat on sunny days. Since metal roofs are permanent, you'll save on repair and replacement costs also.
The next time that you have an HVAC technician at your home or business, ask them to put in a thermostat that is programmable. This will help you to regulate the temperature at all times.
Seek references when hiring an HVAC contractor. You need to know if previous clients have gotten what they needed, like timely service within their budget. That is why it is vital that you check references, so you don't run into those shady contractors!
If you are buying a new HVAC unit, make sure that the one you choose fits your home. Your contractor should inspect your home and your duct work before they install a new unit. If the ductwork needs replacement or repair, this should be done before the new unit is installed.
With all of these great ideas fresh in your mind, go out and find the HVAC help you need. Whether you have to hire a contractor or do the work yourself, your knowledge will get you a long way. All you have to do today is get started on your project!
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.
