Make Better Choices Thanks To This HVAC Advice
When properly maintained, your home's HVAC system isn't something you notice. You just walk in the door and enjoy an air temperature and quality you find comfortable. When your home HVAC isn't working right though, everyone knows. Keep reading this article for advice on ideas on proper installation and maintenance of your home's heating, ventilation and air conditioning.
Ask for referrals when hiring someone to install your HVAC system. Someone may seem like they know what they are doing, but you cannot simply take their word for it. You should be able to call past customers to get an idea of what to expect from this particular installer.
Be sure to get every quote or estimate in written form. You have no recourse on a verbal agreement, so a written contract is a must. This will allow you to follow up if something goes wrong or you don't get what you were promised, protecting you from shady contractors.
When you are no longer using your outdoor air conditioning unit, be sure to protect it with a tight cover. This will keep it free of debris, frost and snow so that you'll have a working unit when the spring comes and you are ready to uncover it and use it again.
If you want to seriously extend the life of your HVAC system, as well as cut down your overall power bill, install ceiling fans in commonly used warm season rooms. Energy-star certified ceiling fans can sometimes cut your HVAC use in half. However, you won't physically notice a difference in temperature.
Change your air conditioner filter quarterly, or four times a year. This not only keeps the air coming into your home easier and cleaner to breathe, it takes a lot of stress off of your AC unit itself. You get to enjoy health, money savings and reduced energy use altogether at once.
Use plants to increase your air conditioner's effectiveness. An AC unit fully shaded by trees and shrubbery can operate up to 10 percent more efficiently. However, do keep spacing in mind. Air flow must not be constricted, and technicians need room to work when they come out to service your unit.
Ask for references and be sure to call them as well. You are dealing with a high ticket item here, so you'll want to do your due diligence to make sure you are getting the best for your money. Ask for references, but don't stop there. Call each reference to check. A lot of people don't take that important last step.
To know how large of an air conditioner you need, look for a calculator online. If you get a unit that is too large, it will cost a lot in energy costs. Check your manual to learn what it is rated by the manufacturer if you want accurate information.
To run an efficient HVAC, you must ensure your house is fully insulated. First, check into your attic to find out if you have the right kind of insulation and enough of it. If not, investing in getting that up to grade is better than installing a strong HVAC system!
Every year hire someone to give your HVAC unit routine maintenance. This will ensure that it works properly throughout the entire year. It will also allow you to have lower heating and cooling bills. When your HVAC is running properly, it will use the least amount of energy and save you money.
If your HVAC system is clicking, look for blockages right away. Many times you will find debris hitting that knock up against the fans inside the cooling unit. Removing the debris solves the issue. Check it out yourself first before you call in the professionals.
A radiant barrier is an awesome device which will help improve the efficiency of your HVAC unit. It keeps heat blocked from inside to the outside, and that lowers how much energy it takes to keep your home cool. You might even be able to start living in your attic.
Your HVAC system will run more efficiently if your windows and doors are energy efficient. Make sure they are tightly sealed so air can't seep in. Have them inspected by a professional. This is often a free service.
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.
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.
If you feel like you are spending too much money on your heating and cooling, there is a simple way to reduce this cost. Raise or lower the temperature depending on the season. A single degree in temperature change can equate to almost a nine percent savings in cooling and heating costs.
When buying an air conditioner, you want to find out with a SEER rating of 13 or higher. 13 is the minimum standard set by the government, so higher ratings, while not mandatory, are going to offer you better efficiency. SEER ratings can go as high as 19, so keep this in mind as you shop.
Keep your evaporator coil clean. A dirty coil will cause the unit to strain when cooling air. You can clean the coil yourself easily. Simply remove the front panel to expose the coil and use a soft brush attached to a vacuum to remove any dust and debris that has accumulated on the coil.
Keeping your HVAC system in good working order is very important to your home's environment. When it goes bad, it can make living at your house a nightmare. Thanfully, the tips from above provided you with excellent tips to keep your HVAC system lasting a very long time. Refer back to them from time to time to ensure that it does not go bad more info on you.
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.
