Anyone Can Become Knowledgeable About Hvac With These Easy Tips
If you've been wondering if you can learn a little bit about HVAC, then this article is something you should try reading over. It's going to teach you the basics when it comes to this type of thing. This will allow you to get to know what needs to be known about this under your belt.
Prior to putting in a service call on your HVAC, be able to identify it. It is important to understand what model it is and which brand it is. Also, if it has been serviced before, you should have that information handy. This will help make sure that the contractor you hire has all the necessary information.
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.
Do you hear a clicking sound when your fan is turning? This may mean that there is something in the way of the blades of the fan. If it gets so bad that the blade bends, you must replace it, just unbending it will leave the fan unbalanced and can cause further issues.
Think about what improvements you want made before picking an HVAC contractor. It will be hard for a contractor to give you a price estimate over the phone if they have not seen your current system. It will be way more hard if you can't figure out what they need to do. Understand this information beforehand.

Be sure you have the HVAC unit in your home checked about two times every year. The normally recommended time for HVAC system inspections is once before the peak cooling season when it gets hot and you'll be using your AC, and once before the peak heating season, during the cold months when you're likely to be using your heat. You should have it looked at even if no problems are occurring; there could still be a problem or potential problem.

If you currently have a manual thermostat, consider installing a programmable one. You can set your system for different temperatures depending on time of day and if anyone is home. Also, you can set upper and lower temperature settings to allow for a comfortable range of temperatures so that heating and cooling don't kick in when not needed.
Consider window air conditioners for your home if you are thinking about installing a central unit. Do you really need to cool your kitchen overnight? Do you have multiple floors with only one housing bedrooms? To efficiently and cheaply cool only where people are actually staying, window units are a great choice.
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.
Do you want to make sure your HVAC unit works for you like it should? It is important to have your unit maintained on a regular basis. Any reputable technician will know exactly what you mean if you call them and ask for a maintenance service on your system.
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 click here 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.
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.
Learn the rules and regulations regarding licenses and insurance before hiring an HVAC professional. This way you can check to make sure that any contractor you consider hiring meets any requirements. This can prevent a costly legal process, especially in case of an accident on site. Without insurance, you could be held liable for damages.
Think about installing a digital programmable thermostat to keep your heating and cooling bills low. These digital thermostats have timers that allow you to completely control your HVAC use. You can set the heat and cooling to only turn on when you are home and to turn off when you are at work.
Always get some references before hiring any contractor. This will show you their overall experience. If you check references carefully, you can avoid being scammed.
Do not let the heat build up inside your home. Lighting, electronic devices and appliances are all common sources of heat inside the home. To prevent this excessive heat, do not put televisions or lamps close to your a/c's thermostat. These appliances make the a/c think that the house is hotter than it really is, causing the system to run longer than needed and wasting energy.
It is tough to deny the fact that a failed HVAC system can wreak havoc in the life of any homeowner, particularly during times of extreme weather. Fortunately, there are things that can be done to mitigate the frustration experienced during such events. Using the advice presented above is a great way to stay prepared.
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.
