Great Advice And Ideas About Hvac That Anyone Can Grasp
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.
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.
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.
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.
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.
When you're purchasing an HVAC system, make sure that you get a unit that is properly sized for your space. If you get a unit that is too large, it will cost a lot in energy costs. Look in the manual or on the manufacturer website for this information.
Keep your condensers free of nearby obstructions. Keep plants, fencing, even bushes back and away from the unit. Two feet is a good minimum distance it should have from anything, including walls, but the more space you give it to breathe, the better it will work and the less likely it will be to fail.
Whenever possible, try to shade the compressor unit outside. The air that's in a place that is shaded is usually five to six degrees cooler than the surrounding air. Your air conditioning unit will be up to ten percent more efficient if it is properly shaded during the summer months.
Always ask for references before you allow anyone to start doing work on your HVAC system. Call several of them to make sure that they are legitimate. Many people take the word of the contractor when it comes to customer satisfaction and that can prove to be a mistake in the end.
Before having someone install a new HVAC system or maintain or repair yours, make sure they are insured. Having someone who is insured work on your system will assure that if anything happens while they are working at your home, they are financially covered and you will not be responsible.
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.
Whether you have an air conditioner in a window or outside your home, be sure to keep it in the shade. The cooler the air around it, and the cooler the condenser itself, the easier a time it will have of keeping the air inside your home cool as well.
Make sure your HVAC is clear when working outside. You should try keeping any vegetation about two feet away from your outdoor units. Keep the areas above it and on each side of it clear. Make sure you aim your grass clippings away from the unit when mowing. Keep leaves from getting inside your unit in the fall.
Call in a contractor to find out if you can install an air conditioner on your current forced-air system without having to install new duct work. This can save you a ton of time and money, plus it takes up less space in your walls and rooms to boot.
Think about the air flow coming out of the air conditioner and where you want to place it for maximum comfort. If you're stuck with putting it in a corner, buy one that lets the air flow to be redirected so that it is not more info flowing towards the wall.
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.
Make sure to be specific about everything that is written in your contracts. It should detail the work that is being done, the materials being used and the amount of time it will take to complete the job. Leaving anything out can give the contractor an exit if something goes wrong.
Every season inspect the outdoor condenser unit of your HVAC system. Remove any weeds and leaves that may be obstructing air flow to the unit. Hose off the inside and outside of the unit to remove any dirt build up. Cover the motor with plastic bags prior to rinsing the unit so that you do not get it wet.
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 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.
