Great HVAC Ideas From People Who Know All About It
Have you ever found yourself shivering during the winter, no matter how hard your furnace works? Does your air conditioner seem incapable of cooling you off in the summer? It may be time to have your old HVAC system replaced with a new one. For tips on finding the right system, keep reading.
Ask for referrals when hiring someone to install your HVAC system. Someone may seem like they know what they are doing, but you cannot simply take their word for it. You should be able to call past customers to get an idea of what to expect from this particular installer.
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.
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 the coils on the condenser fan from time to time. Before you do so, shut off the power to ensure that none of the parts will move while you work on it. Secondly, pop the grill off, take the blades off and clean them as well as the actual unit.
Manage the heat flow into your home with window coverings to help out your HVAC system. In the warmer months, use drapes, curtains and blinds to block out sunward facing windows to keep heat from building up through the greenhouse effect. Alternatively, make sure that sunlit windows are letting light and warmth in during the colder months.
Don't let your home get way too hot to where it's dangerous. Air conditioners can cool a home by just twenty degrees in a short time. This means that if the weather is above 100 degrees, then you'll still be baking in 80 degree weather at first! This can still be way too warm for you.
Whenever possible, try to shade the compressor unit outside. The air that's in a place that is shaded is usually five to six degrees cooler than the surrounding air. Your air conditioning unit will be up to ten percent more efficient if it is properly shaded during the summer months.
Make sure to make a well-informed decision on the size of your HVAC. If the unit is too large, it won't cool more than a smaller unit, just less efficiently. Always look through the manual as well.
Whether you have an air conditioner in a window or outside your home, be sure to keep it in the shade. The cooler the air around it, and the cooler the condenser itself, the easier a time it will have of keeping the air inside your home cool as well.
If you can, find a way to create shade over your outdoor HVAC unit. This can actually save you money as shaded air being pulled in by the HVAC unit is typically 5 to 6 degrees cooler than air that's heated by direct sunlight. It's a smart solution to lowering those energy bills.
Any contractor that gives you a quote over the phone shouldn't be trusted. To truly evaluate your needs, they must come into your home and check it out basement to attic. If they make promises without even seeing your house, there is no way they'll be able to keep them.
If the HVAC unit makes a clicking noise, look immediately to see if there is an obstruction. Most of the time such a here noise is created by an object striking the blades of the fan in the system. Simply clear away the debris or remove any foreign objects and your problem is solved. Before you call a technician, look at it yourself.
When buying an air conditioner, you want to find out with a SEER rating of 13 or higher. 13 is the minimum standard set by the government, so higher ratings, while not mandatory, are going to offer you better efficiency. SEER ratings can go as high as 19, so keep this in mind as you shop.
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.
Learn the rules and regulations regarding licenses and insurance before hiring an HVAC professional. This way you can check to make sure that any contractor you consider hiring meets any requirements. This can prevent a costly legal process, especially in case of an accident on site. Without insurance, you could be held liable for damages.
Consider how long a contractor has been in business before you hire them. The longer they've been in your community, the more likely they are to do a good job. Fly by night operations pop up wherever people haven't heard of them before, and they're just the firms you want to avoid.
To boost your home HVAC's efficiency, install solar screening. It reflects sunlight back outside, stopping it from heating up your home. Your air conditioner will be able to run less in the daytime, and your energy bill will plummet as a result. You can install this on any glass you have, doors or windows.
If you want to buy a new HVAC unit or system, ask a contractor to come up to size up your home and tell you what options you have. They'll have the best advice as they know what sort of systems work in your area or in a home like yours.
Use these tips to keep your HVAC system in tip-top condition. It's a dreadful feeling if you come home and realize your vents don't have air coming out. Repair costs are a nightmare. By using the above information, you can prevent this from happening. Remember these hints when taking care of your HVAC system.
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.
