Your HVAC Should Be Working For You, Here's How
HVAC, or heating, ventilation and air conditioning, is how your home stays warm in the winter and cool in the summer. When properly installed and maintained, you and your family get to enjoy reasonable indoor temperatures all year long. Keep reading this article for advice on installation, upgrades, maintenance and repairs of your home HVAC system.
Do not be surprised if the HVAC contractor you choose does an evaluation on your home. Any good contractor will spend time looking at the system you currently have and what the needs are for your home. They will also take a look at your duct system and look for air leaks.
If you must hire someone to help you out with your HVAC system, be sure to learn about all of the requirements your state has legislated regarding licencing and insurance. You need to be able to ask anyone you plan to hire if they meet these requirements before you hire them.
Make sure you ask for an estimate in writing before choosing a specific HVAC vendor. There are a lot of moving pieces when it comes to purchasing these big items. You'll want to compare not only the cost of the equipment, but also the set up and the overall energy costs.
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.
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!
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.
When you are looking for a service provider to perform service on your HVAC system, look for a company that stands behind their work. This is especially important if your compressor or condenser is being repaired. Repairs to these two things are extremely expensive, so you want to ensure that the service provider warranties their work.
Installing a whole-house fan can either cool your home without the use of air conditioning or make your air conditioner more efficient. It blows out all of the hot air which collects in your attic, and this air flow draws in cool air from your basement and up into your home.
You can get ice in your air conditioner. In addition, the drain line sometimes freezes, and people often think that there is a plumbing leak. If this happens, turn the thermostat so it is on fan only mode, which will disable the compressor. Once you know the problem, contact a local HVAC professional and let them know what's going on in your system.
Every year hire someone to give your HVAC unit routine maintenance. This will ensure that it works properly throughout the entire year. It will also allow you to have lower heating and cooling bills. When your HVAC is running properly, it will use the least amount of energy and save you money.
Before you get into the hot summer months, make sure to schedule a tune up for your current HVAC system. This is very important to keep issues from popping up with your system. It's a small cost to pay compared to the large bills to fix issues that could arise.
Improve the efficiency of your air conditioning by installing ceiling fans. Change the airflow direction of the ceiling fans. During the summer, the blades should move in a counter-clockwise direction. During the winter, the blades should move clockwise to help move the hot air in the ceiling down into the room.
Never hire an HVAC contractor that does not hold a valid license from your state. There are people out there that will offer to do less expensive work since they have no license. While it may seem like a bargain, you will have lots of issues in the event that something goes wrong.
There is a lot to think about when you install an air conditioner unit. For example, a big unit won't remove humidity while a small unit won't cool enough. Placing it in the wrong place can make it less efficient, and not insulating your home adequately could render it almost useless.
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 posted all over the Web. There is a chance that the contractor is posting their own reviews or paying others to do so.
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.
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.
Is your home's electrical set-up ready to handle a new air conditioning unit? Most homes have 115-volt circuits in place, but larger air conditioners need 230-volts to be used. Some smaller units may need their own dedicated circuit as well to ensure your home doesn't go dark when you turn them on.
As the beginning of this article discussed, you need to have a great HVAC system in order to feel comfortable in your own home. read more The best way to get this kind of system is when you are educated on the topic. The above article gave you the important information you needed.
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.
