Don't Go On Without Reading This Article About HVAC
Your HVAC system at home is probably the most vital piece of equipment that you have. Unfortunately, many people fail to realize this, and they end up having major problems with it. Don't let your HVAC system go bad on you, read the tips below for solid information that will help you out.
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.
One of the most important things to consider when purchasing a new heating and cooling system is the manufacturer's warranty. Units come with a variety of warranties. Choose one with a long warranty for maximum long term savings. Generally, it is advised that homeowners should purchase the extended warranty if one is offered.
If you do have a good experience with a HVAC product or contractor, let others know. Go online and post a review so that people can easily find out who and what brands to trust. At the same time, you can check reviews online to learn more yourself about what's available.
If you want to turn off your air conditioning at night to save money, consider putting a standing fan next to your bed. You can set it to oscillate from your toes to your head, blowing cool air over your body and letting you sleep comfortably all night long.
Do you hear a clicking sound when your fan is turning? This may mean that there is something in the way of the blades of the fan. If it gets so bad that the blade bends, you must replace it, just unbending it will leave the fan unbalanced and can cause further issues.
To save money on your HVAC system, turn the air conditioning down at night and let your home warm up a bit. To keep yourself cool, use a chilling water-filled pillow to cool down your head and your whole body as a result. This combined with a fan will keep you from overheating while saving on your utility bills.
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.
To know how large of an air conditioner you need, look for a calculator online. If you get a unit that is too large, it will cost a lot in energy costs. Check your manual to learn what it is rated by the manufacturer if you want accurate information.
The energy efficiency of a unit should be taken into consideration when purchasing a new heating and cooling system. Although you should be concerned about the price of a unit, the efficiency of the unit will save you thousands over the lifetime of the heating and cooling system and should weigh heavily on your buying decision.
Use plants to increase your air conditioner's effectiveness. An AC unit fully shaded by trees and shrubbery can operate up to 10 percent more efficiently. However, do keep spacing in mind. Air flow must not be constricted, and technicians need room to check here work when they come out to service your unit.
Be careful of sounds in your HVAC. If the condenser fan begins to make a grating or clicking sound, the blades could be hitting an obstruction. If blades get bent, don't try straightening them. You could unbalance them and cause them to hit the condenser coil. This could loosen the motor in the fan. Try replacing the bent blades with new ones. Make sure the new blades can freely rotate without wobbling.
To block out the sun on hot summer days, allowing your air conditioner to run less frequently, invest in heat blocking drapes. These textiles come in beautiful patterns and colors today, looking just like their designer counterparts. They will keep the heat out so that your home stays cooler without costing you an arm and a leg on utility bills.
Check the licensing of any HVAC company that you plan to hire. Start by making sure they are fully licensed. They should be in compliance with your state's business laws. Good HVAC companies should be fully insured. This is to protect their company, their employees, and their customers should anything happen when they are performing a service at the home of a customer.
You should focus on finding an HVAC contractor that can offer you a warranty on the work they are doing. This is a sign that they are confident in their ability to get the job done well. This will protect you in the event that is not done right and needs to be fixed.
Make sure your HVAC is clear when working outside. You should try keeping any vegetation about two feet away from your outdoor units. Keep the areas above it and on each side of it clear. Make sure you aim your grass clippings away from the unit when mowing. Keep leaves from getting inside your unit in the fall.
If you feel like you are spending too much money on your heating and cooling, there is a simple way to reduce this cost. Raise or lower the temperature depending on the season. A single degree in temperature change can equate to almost a nine percent savings in cooling and heating costs.
Hire contractors who offer guarantees of at least 5 year on all labor and parts. This will ensure that you can go back to them to fix anything that goes wrong shortly after your system is installed or repaired. Anyone who doesn't offer a guarantee won't come back unless you pay them again.
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.
After reading the above article, you now have a greater understanding on the importance of keeping your HVAC system in good working order. Remember the solid tips here as you know what to look out for, so no HVAC problems turn into major disasters. Study the tips and use them as you perform regular maintenance on 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.
