2. What Is An HVAC?
AN HVAC SYSTEM IS DESIGNED TO CONTROL THE ENVIRONMENT IN
WHICH IT WORKS.
IT ACHIEVES THIS BY CONTROLLING THE TEMPERATURE OF A ROOM
THROUGH HEATING AND COOLING. IT ALSO CONTROLS THE HUMIDITY
LEVEL IN THAT ENVIRONMENT BY CONTROLLING THE MOVEMENT AND
DISTRIBUTION OF AIR INSIDE THE ROOM.
THE SYSTEM ALSO ENSURES CLEANLINESS OF AIR INSIDE THE SAID
ENVIRONMENT.

3. Types of HVAC Systems Available
 The three main types of HVAC systems available today are:
 Split and Window AC
 Packaged Heating & Air Conditioning System
 Central AC System

 Aeroseal Duct Sealing
 Zoning Systems
 Ductless Systems
 Geothermal Heating and Cooling
 Movement-Activated Air Conditioning
 Thermally Driven Air Conditioning
 Ice-Powered Air Conditioning

12. Improved Energy Efficiency
 Energy-efficient heating and cooling systems have come a long way
during the past two decades. If your current HVAC system isn’t
Energy Star certified, you could be wasting substantial energy and
money every time you heat or cool your home.
 HVAC systems that have Energy Star certification have met or
exceeded national efficiency standards. They can help you go green
while lowering your utility bills.

13. High-Tech Cooling Features
 Keeping your Lockhart home cool doesn’t have to be complicated,
especially when you invest in an air conditioner that boasts the latest
high-tech cooling features. For example, variable-speed air
conditioners have the power to adjust the airflow in your home
automatically. They can keep your family comfortable without
wasting energy.
 Scroll compressors can give refrigerant extra pressure and use less
energy. They provide air conditioners with more power to cool your
home in less time.

14. Smart Thermostats
 If you haven’t replaced your old manual thermostat with a Wi-Fi-
enabled model yet, this is a great time to take the plunge. The smart
thermostats of today can connect to your home’s central hub and
become a key part of your smart home.
 When our team installs a Nest thermostat for your HVAC system,
we can connect it to your home’s Wi-Fi network. We can show you
how to program it, and make sure you can log in and adjust it from
your smartphone. Not only can a smart thermostat add convenience
but it can also help with energy savings.

15. Aeroseal Duct Sealing
 Most ductwork systems develop cracks, leaks, and general wear and
tear as they age. Over time, this wear and tear can cause HVAC
efficiency and performance issues. But duct repair and sealing can
help.
 In recent years, Aeroseal has taken duct sealing to new heights,
thanks to its innovative process and great results. This process
involves spraying a liquid substance into ductwork, applying
pressure to force the material to adhere to cracks and seal leaks.

16. Zoning Systems
 If your home is on the large side, a standard HVAC system can’t
always keep your family comfortable. That’s especially true if your
home has more than one floor or areas that receive much more sun
exposure.
 Zoning can effectively turn one heating and cooling system into a
multifaceted system with two or more areas that have separate
climate control settings. Introducing zoning systems is as easy as
installing a series of dampers in the ductwork and adding
thermostats for each zone. They can help take your comfort and
energy savings to the next level.

17. Ductless Systems
 If you don’t want to deal with ductwork, consider a ductless heat
pump or air conditioning system. These mini-split systems connect
indoor units directly to outdoor units, and a single unit is designed to
cool one room or an isolated part of your home.
 They can be smart additions to parts of your home that can be
challenging to heat or cool, such as sunrooms, new additions and
newly finished rooms. They’re a great option if you don’t want the
hassle or added expense of new ducts.

18. Geothermal Heating and Cooling
 If you really want to go green, geothermal heating and
cooling could be a great investment. This type of system
draws energy from the ground under your home, helping
you reduce your carbon footprint substantially.
 A geothermal heat pump can be a major investment. But
these durable, low-maintenance systems can be great
choices if you’re seeking a long-term HVAC investment.

19. Movement-Activated Air Conditioning
 Engineers at MIT have come up with a new air conditioning design that
utilizes sensors along aluminum rods hung from the ceiling. Movement then
activates these sensors. In other words, the air conditioner only kicks on when
people are present.
 A motion-activated system seems like such a simple, ingenious idea that it’s
almost baffling it hasn’t been tried before now. However, this kind of
prototype is just one example of how future HVAC systems are going to be
more compact and portable, helping to reduce both energy and utility costs.

20. Thermally Driven Air Conditioning
 Another design that’s recently been implemented is thermally driven air
conditioning. An Australian company named Chromasun has produced a
low-cost alternative to traditional A/C units. It isn’t a widespread technology
yet, and it will likely be several years before this kind of design becomes
widely available in the United States. However, thermally driven air
conditioning is a system that uses solar energy and is supplemented by
natural gas, making it a highly efficient and effective system.
 In fact, the double-chiller design provides more cooling capabilities than any
other system so far, and it eliminates electricity costs altogether.

21. Ice-Powered Air Conditioning
 Air conditioners seem to be prime systems for tweaking and making better.
That’s why a California-based company has created an ice-powered A/C
system called the Ice Bear. The Ice Bear essentially works by freezing water in
a tank overnight, so the ice can help cool a building the next day. So far, the
design has been able to provide enough cooling for a building for up to six
hours, after which, a conventional commercial air conditioner takes over.
 Although this type of technology has quite a way to go before it can be the
sole cooling system for a home, six straight hours of cooling a commercial
building is a solid step in the right direction.

22. Fully Automated Homes
 As if owning a smart home wasn’t convenient enough, fully automated homes
will soon become a reality. There are already technological solutions on the
market that are allowing companies to experiment with automated appliances
and other products. Therefore, it’s only natural that HVAC systems will one
day be directly tied into other systems in your home, making adjustments
according to the status of the rest of the house.

23. Harnessing Heat from a Computer
 If you own a laptop and have ever used it for several hours in one setting, you
know how much heat it begins to generate. One innovator named Lawrence
Orsini, founder of Project Exergy, has seen how efficient computers are at
generating heat. This is why he’s theorized they can be used for powering
heating systems.
