The Best Advice For Buying HVAC Equipment
Dealing with HVAC trouble can be a frightening scenario for anyone who is unfamiliar with the best ways to identify reputable, qualified contractors. The most important thing a homeowner can do is to educate themselves thoroughly on the process before any needs arise. The article below can help everyone do just that.
Before selecting a HVAC repairman, know what you need done. If you can't describe the problem, you may not get an accurate quote. If you are unable to explain the work that needs to be taken care of, the conversation will be even less fruitful. You need to know this before you begin.
Look for deals and rebates on the HVAC system you are having installed. Many ENERGY STAR units come with huge rebates either from your local utility company or the government itself. Investigate your options as it could save you hundreds or even thousands of dollars on the installation costs.
Clean the condenser coils and fan at the beginning of the year to help the unit run efficiently. Always turn the unit off before you do anything to it, including leaning. Also, be sure to clear leaves and debris from your condenser unit.
Think about what improvements you want made before picking an HVAC contractor. It's hard to get an estimate since they haven't look at your system. They need to come look at the unit. So, know this information in advance.
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.
It is a good idea to replace single-paned windows with ones that have double panes. Having a double pane window helps limit your need for air conditioning during the summer months. This same effect also keeps warm air in during the winter months.
If you have a window air conditioner without a timer, use a regular outlet timer to control when it is on or off. These are the same ones you use for holiday lights, so all you have to do is plug your air conditioner into the timer and set it to cool you during the day.
Problems with an air conditioning unit happen when it ices up. There are sometimes also freezes that happen in a drain line, and this can be confused for a plumbing leak. If this happens, put your thermostat over to fan. The ice will melt. You will likely need professional help to stop the here problem.
There is no denying the fact that confronting issues with a HVAC system can be scary for those not in the know. Finding a great local contractor to install new equipment or repair the old can be a challenge without great tips and advice. Luckily, the information presented above can serve as an easy reference anyone can use.
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.
