Great HVAC Ideas From People Who Know All About It
HVAC, or heating, ventilation and air conditioning, is how your home stays warm in the winter and cool in the summer. When properly installed and maintained, you and your family get to enjoy reasonable indoor temperatures all year long. Keep reading this article for advice on installation, upgrades, maintenance and repairs of your home HVAC system.
If you want to keep your air conditioning unit running efficiently, make sure you replace or clean the air filter once a month. Check the owner's manual on the a/c for instructions on how to clean the filter. Never run the unit when the filter is removed and let the filter dry before reinstallling it.
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.
Get any agreement with an HVAC contractor in writing. Some contractors try to skip over this step and charge customers a fortune. If you have a certain price and warranty in writing, they cannot go back and change this information. If they do, they could have a lawsuit on their hands.
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.
If you want to know more about efficiently heating or cooling your home, go online and download the ENERGY STAR Guide. It provides information for homeowners to learn more about how they can save money while still keeping their home comfortable all year round, so it is a worthy ready.
In order to cheaply cool your home, turn the temperature up. If you take a few showers a day or just drink a cold ice water, you'll find that you're saving a lot of money on your utility bills by keeping the thermostat a little higher than usual in your home.
When you are looking for a service provider to perform service on your HVAC system, look for a company that stands behind their work. This is especially important if your compressor or condenser is being repaired. Repairs to these two things are extremely expensive, so you want to ensure that the service provider warranties their work.
Make sure that your contractor provides a home assessment. Not every HVAC solution is for everyone. Your home could have special needs for heating and cooling. Your contractor should do a walk around of your space to judge what is best. If they aren't be sure to here request one.
You can get ice in your air conditioner. In addition, the drain line sometimes freezes, and people often think that there is a plumbing leak. If this happens, turn the thermostat so it is on fan only mode, which will disable the compressor. Once you know the problem, contact a local HVAC professional and let them know what's going on in your system.
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.
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.
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 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.
Want to save the most you can with your HVAC unit? Consider increasing your room temperature by a single degree or two. Each degree means money that stays in your pocket. In fact some estimate that each degree you move up can work out to be around 9% in overall energy savings.
The biggest step to preventing problems in your air conditioner is getting a professional tune-up once a year. This is especially important before the summer. This is when your air conditioning system will be working its hardest. Getting regular tune-ups reduces the risk of malfunctions and will keep you cool all summer long.
Is your home's electrical set-up ready to handle a new air conditioning unit? Most homes have 115-volt circuits in place, but larger air conditioners need 230-volts to be used. Some smaller units may need their own dedicated circuit as well to ensure your home doesn't go dark when you turn them on.
The biggest step to preventing problems in your air conditioner is getting a professional tune-up once a year. This is especially important before the summer. This is when your air conditioning system will be working its hardest. Getting regular tune-ups reduces the risk of malfunctions and will keep you cool all summer long.
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 stated in the introduction, it is your home's HVAC system that lets you enjoy a consistent indoor temperature range all year long. Regardless of the season, your properly maintained home heating, ventilation and air conditioning means you rest comfortably inside. Use the advice from this article to make sure that your home stays the temperature you want.
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.
