Helpful Hints For HVAC Novices And Pros
It is important to educate yourself on your HVAC system. You'll find some great information in the following article that will give you the basics. Take some time to read carefully and you will do just fine.
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.
Clean the coils of your condenser fan each month. Turn off your power before doing any job like this. Leaves and debris can build up inside the unit and cause damage.
Don't let your outdoor HVAC units get smothered with clippings anytime you mow the yard. Direct the clippings away from the equipment. This is the same if you are using a leaf blower.
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.
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.
Don't let your home get way too hot to where it's dangerous. Air conditioners can cool a home by just twenty degrees in a short time. This means that if the weather is above 100 degrees, then you'll still be baking in 80 degree weather at first! This can still be way too warm for you.
Make sure the equipment you are buying is ENERGY STAR compliant. It may seem a small thing, but it isn't. Products that are ENERGY STAR compliant can save you a lot of money in energy costs over the year. It can be over $100 easily, sometimes a lot more.
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.
When you buy a new air conditioning unit, don't let the salesperson talk you into too large of a unit. This will be a waste of money and won't efficiently cool your home. The longer a system runs, the more efficient it will be when it's running, so look for one which runs 15 to 30 minutes.
Are you looking at purchasing a HVAC system? You should first think about several things. Those systems get rated by the area amount they are able to cool and heat effectively. You want a unit which offers a little more than you need.
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 here create issues for your system. Just this little clean up can save you a lot of money in maintenance bills.
Choose a good HVAC company. You need to find one that has a solid reputation. It's important that it has been around for several years and is backed by a good reputation in customer service. Find one that has trained professionals and qualified technicians to help with all kinds of customer needs. They should be able to handle any HVAC job no matter how simple or complex.
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.
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.
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.
Choose a contractor who knows how to work with your current system. If they work with that set-up frequently, they'll quickly diagnose any problems and know exactly how to maintain it. Choosing such a firm will save you time and money, and will also save you from unnecessary headaches.
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.
As you can see, finding the perfect HVAC system for your home can be tricky. There is a lot of information that you need to absorb before you can make the right decision. By keeping this advice in mind, you can find a great new system that will keep you comfortable all year 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.
