Great Advice About Hvac That Anyone Can Easily Follow
The HVAC system in any home is vital to maintaining a comfortable environment. Perhaps you are here because you have experienced problems with it in the past, or you just looking for information on how to properly maintain it. Either way, the article below is a great resource on the upkeep of HVAC systems.
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.

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.
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 have a window air conditioner, be sure to check and see if it has an Energy Saver button. If so, use it! This turns off the fan when the unit isn't actually cooling the air, which can save you as much as 30 kwh over the period of a month!
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.
There are sizing calculators available to determine the proper sized system for your home. If the unit is too large, it won't cool more than a smaller unit, just less efficiently. Check your manual to learn what it is rated by the manufacturer if you want accurate information.
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.
Do you need a new cooling system? There are a number of things to think about first. First, the rating a system has indicates how much area they can warm up or cool down. You want a unit which offers a little more than you need.
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 month clean out the leaves and debris that may have settled into your outdoor HVAC unit. You'll be surprised at how much gets caught in your unit. Over time these leaves can build up and create issues for your system. Just this little clean up can save you a lot of money in maintenance bills.
When you are looking to buy a new air conditioner, consider your climate. If you live in a hot, dry area, then an evaporative cooler will be your best bet. If you live in a humid area, opt for a compressor-style unit as it's the only one which will work.
When water condenses on your air conditioner, it drips into a pan and drains out. This drain should be inspected on a regular basis. If algae forms in the drain line or if the drain line freezes, you could be in for some expensive repairs. The drip pan could overflow causing extensive damage to your ceilings.
If you plan on having a service on your HVAC unit, ask the technician what he will be doing. Any thorough service should consist of several things. The technician should check temperature levels, pressures, amperage draw, and coolant levels. They should adjust any belts that need it and clean the coils.
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.
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.
When you hire a contractor to do a job, be sure to listen to what they tell you. For example, they can give you advice on how to keep your HVAC in working order. Ask about maintenance tips and how often you should be cleaning or servicing the unit.
If you are buying a new HVAC unit, make sure that the one you choose fits your home. Your contractor should inspect your home and your duct work before they install here a new unit. If the ductwork needs replacement or repair, this should be done before the new unit is installed.
After reading the above article, you now have a greater understanding on the importance of keeping your HVAC system in good working order. Remember the solid tips here as you know what to look out for, so no HVAC problems turn into major disasters. Study the tips and use them as you perform regular maintenance on 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.
