What You Need To Learn Before Calling An HVAC Tech For Help
One of the most important things in a home can be its HVAC system, and it is vital that any homeowner understand how it works. If you would like good tips on how to maintain your HVAC system, then the following article is for you. Read on and learn and get beneficial information that can help you better understand your HVAC system.
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.
When seeking a new contractor, ask loved ones for referrals. They'll often have already had someone in for similar work and will know who to trust and who to avoid. If your family hasn't used anyone, ask co-workers or other people you trust in your community for some references.
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.
Clean the coils on the condenser fan from time to time. Before you do so, shut off the power to ensure that none of the parts will move while you work on it. Secondly, pop the grill off, take the blades off and clean them as well as the actual unit.
Look to your neighbors and family to get recommendations of good HVAC specialists. Likely there's someone you know who's already done a ton of research. Use this knowledge to help get you the best specialist you can. This can save you many hours of research time and money too.
Your system should be checked twice a 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. Even if you do not detect a problem, you can identify and fix any potential problems when you have it checked.
Go to people that you know and ask for recommendations when it is time for you to hire an HVAC contractor. People usually love to boast about the wonderful work they have had done, so you should be given great leads to follow. This will also help you to avoid undesirable companies.
Clean your filters! If you have a window unit air conditioner, there will be a filter right under the grill you can vacuum. If you have a furnace or outdoor units, they will also have filters to be cleaned or replace. A dirty filter can make your unit inefficient or even let it overheat.
The energy efficiency of a unit should be taken into consideration when purchasing a new heating and cooling system. Although you should be concerned about the price of a unit, the efficiency of the unit will save you thousands over the lifetime of the heating and cooling system and should weigh heavily on your buying decision.
If you can, find a way to create shade over your outdoor HVAC unit. This can actually save you money as shaded air being pulled in by the HVAC unit is typically 5 to 6 degrees cooler than air that's heated by direct sunlight. It's a smart solution to lowering those energy bills.
If you live in a hot climate, don't use duct tape on your HVAC. It just dries out and falls off, leaving you with leaks all over the place. Instead, use mastic sealant to cover any holes or gaps in duct work and you'll keep your home comfortable all year long.
Have your HVAC inspected every year to ensure that it is working properly. The technician will check your filters, drain lines, air flow and Freon levels. This will have your HVAC working at peak performance saving you money all season long. It will also alert you to any repairs that need to be address before they become big problems.
Never hire anyone to work on your HVAC system unless they read more are licensed and bonded. This industry is one where mistakes happen often and you want to make sure that you are protected. You do not want to be stuck paying for medical bills that are more expensive than the work you were having done.
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.
If your home gets hot in the summer and you'd like to use your air conditioner less often, consider a metal roof. It reflects the heat right back up into the sky, allowing your home to gain less heat on sunny days. Since metal roofs are permanent, you'll save on repair and replacement costs also.
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 you hire a contractor, always ask for references. Talk to those references to find out if they were pleased with the service they received. Make certain to follow through and contact the references provided.
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.
Use these tips to keep your HVAC system in tip-top condition. It's a dreadful feeling if you come home and realize your vents don't have air coming out. Repair costs are a nightmare. By using the above information, you can prevent this from happening. Remember these hints when taking care of your HVAC system.
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.
