Looking For Tips About Hvac? You've Come To The Right Place!
Are there times when you wonder if your air conditioner or furnace is working properly? Is it hard to keep your home at a comfortable temperature? If so, it may be time to look for a new HVAC system. This article has a great deal of useful advice about doing so.
Be aware of the type of system that is installed in your home prior to calling a contractor to fix it. Write down what brand your system is along with the model number and, if they're available, maintenance records. The contractor will likely need all of this information.
When you have an outdoor unit, be sure to keep all plants, flowers, shrubs and trees at least two feet from it. Anything that grows inside it, either above the ground or even roots beneath the soil, can block it up and cause it to break. Give it some breathing room.
When your contractor comes to fix your unit or install a new one, he should walk around your home and investigate what's going on with your current set-up. They should be looking for how much insulation you have, where your windows are and what quality they are and more.
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.
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.
Looking for an efficient way to cool your home? Consider installing a whole-house evaporative cooler. They use water to cool air instead of traditional chemical coolants, using a ton less energy to cool your home than those other units. That said, they do work best in dry climates and not at all in humid ones.
Do not let your house get dangerously hot. Air conditioners cannot sufficiently cool down unreasonably high temps. If your home become 100F or more, it will only cool off to about 80F. If humidity is high, this temp is still unsafe for people.
If you want to pay for less power use, consider installing an HVAC-specific solar panel system. Such an installation harnesses the power of the sun directly for your heating and air conditioning. Don't worry though; you can have a switch put in that automatically connects to the power grid the days there isn't enough sun.
It can be confusing to figure out what the correct HVAC system size is for your home, but you can solve this with the help of a sizing calculator. If the unit is too large, it won't cool more than a smaller unit, just less efficiently. Check the manufacturer's handbook to see what amount of space the unit can effectively cool.
Make sure things don't get too hot or cold where your thermostat is. Any electronics or heat sources like lamps or televisions nearby can trick the thermostat into thinking the home is warmer than it actually is. This just means it runs your air conditioning longer than necessary, wasting energy and money.
Consider an annual service agreement for technicians to regularly inspect your AC unit. Schedule brief inspections for the winter to make sure nothing is obviously wrong. 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.
Now that you know so much about HVAC units, you're ready to take control of your own. Use these tips as you ensure yours is in tip top condition at all times. Continue to learn more about these systems so that your family can rely on you to keep them cool in the summer and warm all winter long.
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.
