Helpful Hints For HVAC Novices And Pros
Has the time come to replace your aging HVAC system? Do you want to upgrade the efficiency of your current set-up? Are you having issues with rooms which are uncomfortable to live in? Regardless of why you are here, this article has the tips and tricks you need to succeed.
When seeking a new contractor, ask loved ones for referrals. They'll often have already had someone in for similar work and will know who to trust and who to avoid. If your family hasn't used anyone, ask co-workers or other people you trust in your community for some references.
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.
Sometimes, it can be hard to figure out if your HVAC system needs to be fixed or needs to be replaced. If your system frequently breaks down, is always turning on or off on its own, or if your bills are too high, it may pay to have it replaced. Otherwise, little things can just be fixed.
Once it gets cold outside, you should turn off the outdoor condenser unit. To avoid damage, units should be turned off when temperatures are below 60 degrees. This helps your system remain in good working order.
To make sure your condenser fan works properly, keep the fan blades and the coils clean. Prior to working on or cleaning the unit, be sure to turn off the power. The outside condenser unit should be kept free of leaves and other debris.
As you compare new HVAC system, be sure to look at the energy ratings for each unit. The higher they are, the better they will be. Efficiency will not only get your home comfortable faster, but it will save you on your energy bills when you are running your new unit.
Consider all of your alternatives before installing a central air conditioner. You can only cool certain rooms, use whole-house fans, or even make use of a geothermal system. The more efficient the system you set up, the less you'll spend on utility bills over time as you use it.
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.
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.

The most important time for an inspection and service is just before it starts getting warm. You don't want to discover an AC breakdown when you need it working most.
Every month clean out the leaves and debris that may have settled into your outdoor HVAC unit. You'll be surprised at how much gets caught in your unit. Over time these leaves can build up and create issues for your system. Just this little check here clean up can save you a lot of money in maintenance bills.
Do you need a new HVAC system? There are a number of things to think about first. Systems have ratings according to the total area they effectively heat or cool. You should buy a little bigger than necessary unit over a little smaller than necessary unit.

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 don't provide regular maintenance, you could have costly fixes down the road. You should not want that, so remember these tips to help you keep your HVAC system running right for many years to come.
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.
