Emerging Answers For Fundamental Concepts For HVAC contractor
A Basic Guide To All Your HVAC Questions And Needs
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.
If your HVAC system is acting up, take a tour of the house prior to calling a professional. While you are walking through the house, gauge which rooms are the coolest and which are the warmest. This can help the contractor determine the problem areas quickly and fix the problem easily.
If your HVAC is running into problems, check out each room in your house before calling for assistance. Make note of which rooms are cold and which are hot. This can help the contractor determine the problem areas quickly and fix the problem easily.
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 trees are losing leaves around your home, this can impact your HVAC unit. Frequently clean the fan grill when trees are shedding leaves. You can head off future problems that can be caused by blockages by making sure there is a free flow of air to your fan.
If the fan condenser on your unit has ports for oil, make sure you lubricate it once a year. Most of these ports have some sort of protective cap covering them. Your oil should be an SAE 20. This particular oil is very lightweight and it only requires about 10 drops per port.
When choosing the area for placing an outdoor compressor device, place it in a shady area. The cooler air entering the unit will require less work to get to the proper temperature.
Do not allow your home to reach excessive levels of heat during the summer. Your average AC unit can only reduce the temperature in your home by about 20 degrees in a normal span of time. So, if your home temp reaches 100 degrees, your air conditioning will only bring that temp down to about 80 degrees. While it depends on the humidity, this is not safe for a human to sleep in to recover from the heat of the summer.
In the winter, wearing layers can save you a ton of money on your utility bill. If you can install a digital thermostat that makes the house cooler when you're asleep and warmer just before you get up, you can see significant savings on your next bill when it arrives.
If you want to pay for less power use, consider installing an HVAC-specific solar panel system. Such an installation harnesses the power of the sun directly for your heating and air conditioning. Don't worry though; you can have a switch put in that automatically connects to the power grid the days there isn't enough sun.
Properly functioning home HVAC means room temperatures indoors in seasons both cold and hot. Improperly functioning home HVAC means variable humidity levels indoors, uncomfortable temperatures and air check here that is possibly even dirty to breathe. Keep your family comfortable, healthy and happy with the ideas within this article about your home's HVAC.
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.
