The future of the HVAC industry is looking bright. We expect to see new developments in the years ahead that will improve our quality of life and make life easier for everyone. This post will look at where the industry is headed. We will also mention some new technologies being developed to help us meet future challenges.

HVAC Industry Trends

The HVAC industry has come a long way in recent years. We have seen a dramatic increase in the use of renewable energy sources, which will only continue in the future. Solar power, wind power, and geothermal energy are all becoming increasingly popular and necessary, In addition, we see a move away from traditional fossil fuels such as coal and oil. This is good news for the environment, but it also presents some challenges for the HVAC industry and pushes us toward more energy-efficient systems.

The Latest Technology

Finding new, more efficient ways to heat and cool homes and businesses is essential. This is the driver for the latest developments in HVAC technologies and improvements. Newer HVAC systems are much more efficient than older models and can help customers save money on consumer energy bills. In addition, newer HVAC systems are much better for the environment and put less demand on our overburdened power infrastructure.

Technologies and Innovations

Here are a few technologies and innovations that are shaping the future of HVAC:

  • Solar-powered HVAC systems are becoming more popular as people look for ways to reduce their carbon footprint. Solar-powered HVAC systems use the sun’s energy to heat and cool buildings.
  • Variable speed compressors are a type of compressor that can save energy by running at different speeds. Variable speed compressors can adjust their speed to match the demand for heating or cooling.
  • Inverter air conditioners are a type of air conditioner that uses less energy than traditional air conditioners. An inverter-driven compressor keeps the motor turned on continuously and adjusts the speed to vary the temperature. This means the power used can vary between 0 and 100 percent. This is more energy-efficient than turning the motor on and off repeatedly.
  • Smart thermostats are a type of thermostat that can be controlled remotely and turn the heating or cooling off when you are not home— all controlled by your smartphone.
  • Geothermal heat pumps are a heating and cooling system that uses the earth’s energy to heat and cool buildings. Geothermal heat pumps are an efficient way to heat and cool the home and save energy.
  • Sensor-enhanced vents are a type of vent that uses sensors to monitor the air quality in a room. Sensor-enhanced vents are an efficient way to improve the air quality in the home and can save on energy.
  • Motion-activated A/C utilizes ceiling sensors to detect movement and will turn on when it senses motion.
  • Thermally driven A/C will utilize solar energy and supplement with natural gas.
  • Ice-powered A/C uses water that is frozen in a tank overnight to help cool the next day. Conventional cooling takes over when the ice has thawed but can last for around 6 hours.

Additional innovations include:

  • Energy data analysis software
  • Dual fuel heat pumps
  • Dual-stage compressors
  • Efficient scroll compressors

Common Air Conditioning Installation Violations and How to Avoid Them

Common Air Conditioning Installation Violations and How to Avoid Them

HVAC installers provide an extremely valuable service: keeping them safe from the extreme heat and extreme cold of the seasons and helping them feel comfortable in their home or office. This job is especially important to the good people here in Texas who face indescribably hot conditions during the summer.

Not many people have the skills that heating and air conditioning installers have, making them a valuable member of the community they work in. As an HVAC professional, people will depend on you and the skills and expertise you possess to get them through the season. 

It is for this reason that knowing 90% of air conditioning installations are done incorrectly is such a disheartening statistic. Even with all respect and expectations customers hold for the profession, almost every installation is not completed to the high standards that HVAC professionals were trained for and should hold themselves accountable to. To be frank, it is shameful.

However, it doesn’t have to be that way. As an incoming HVAC student, a recent graduate of The Training Center of Air Conditioning and Heating, or just someone who is interested in the profession, you have the power to buck this trend and learn from the mistakes of those that have come before you. 

Here are six of the most common air conditioning violations that occur in the field so you can learn to avoid them. 

No Installation Permit

Acquiring the proper permits prior to air conditioning should be one of the very first steps in the process, yet it is often overlooked by both parties involved in the installation: the customer and the contractor. Most homeowners will know they need permits for major home renovations, but many don’t realize that they need one for air conditioning installation as well.

Permits are important for a number of reasons. They not only ensure the safety of those working on the equipment, but they also ensure that the equipment being installed is up to energy and environmental standards. Contractors can obtain the necessary permits on behalf of the homeowner and they can also be obtained by the homeowner themselves.

Installing without permits is often overlooked by homeowners who don’t know and contractors who don’t care – but both should concern themselves about it. Installing an air conditioner without the proper permits isn’t just dangerous but can result in serious fines. As a HVAC contractor, never take an air conditioning installation job without the proper documentation first.

Failure to Perform Manual J, Manual S, or Manual D

No two air conditioning system installations are the same. Each and every system requires very precise calculations and adjustments to ensure they are working properly and efficiently for the environment they are being installed in. Three calculations of particular importance that need to be done with every single installation are Manual J, Manual S, and Manual D calculations. However, these calculations are not consistently done, or done correctly, during many air conditioner installations.

Manual J is a calculation that needs to be done to properly size the system to provide optimal cooling based on the size of the home it is being installed in along with other factors. An air conditioner installed in a larger home will need to be adjusted differently than one in a smaller house in order to keep every room and every person cool. 

Manual S then considers the geographical location of the system and the average temperature highs it will have to perform in. Also known as design temperature, an air conditioner needs to be calibrated to effectively and efficiently work under the conditions it will experience 99% of the season. 

Manual D builds off the previous calculations by determining the proper sizing of the ducts needed to properly distribute air without underworking or overperforming.

Not performing these calculations causes air conditioners to not perform efficiently. If the system is oversized it distributes too much air during each cycle which can spike energy usage and inflate monthly energy bills for the customer in addition to ineffectively controlling humidity. Undersized air conditioners will not be able to keep the customer cool. Both instances make for unhappy customers and the need for unnecessary service calls to correct the system’s settings.

Furnace flue pipe touching combustibles

It is a shame that this needs to be said time and again, but because this is one of the most common air conditioning installation violations done here it goes: never put something very hot in contact with something flammable or combustible!

Every HVAC system has a flue pipe that vents hot exhaust air outside of the home it is installed in. Not only is this air warm, it can also contain carbon monoxide, an odorless and tasteless gas that can be deadly if it is allowed to circulate into a home’s air supply. Proper ventilation of the flue is an important part of HVAC installation, but so is the proper installation and accounting for the surrounding area.

When installed in homes, flues are often installed around wood from the subfloor or the home’s frame, which can be inflamed by the warm air and hot metal duct if the proper clearances are not accounted for. Suficit to say this isn’t just a mistake that costs money to fix, it is a potentially deadly one.

Heating equipment is the number one cause of house fires in the U.S and accounted for 19% of house fire deaths from 2014 to 2018. When installing a flue pipe or servicing a piece of equipment that may cause you to move or adjust the pipe, make sure the proper safety measures are taken before you leave.

Service access to equipment not accessible

Air conditioners need regular care, attention, and servicing to ensure they run properly for as long as possible. However, servicing the system properly can be made much more difficult (both for you and anyone else who might work on it in the future) if it has not been installed with the proper accessibility. 

Here is the long and short of the situation: if it is hard to get to the system it is going to be hard to service it. This means that minor, easy-to-fix issues can get overlooked and become serious ones, cleaning is harder to do thoroughly, and the healthy lifespan of the system can be drastically shortened.

When you are installing an air conditioning system, make sure you are following the proper NEC guidelines for working space of three feet on each side of the equipment. This will allow that yourself and anyone else who needs to work on it has proper access.

Air conditioning installation isn’t always done right. But it doesn’t have to be that way! Understanding where other installers fall short is the first step in training a new generation of air conditioning installers who are hard working, thorough, and masters of the trade. 

That is our mission here at the Training Center of Heating and Air Conditioning. We are based in Houston, Texas and our founder Chris Walters spent his HVAC career practicing in Texas. Through our experiences working in this industry in this state, we know exactly what our students need to know in order to have a successful career upon graduation.

What You and Your Customers Need to Know About R22 Refrigerant

What You and Your Customers Need to Know About R22 Refrigerant

For years, R22 refrigerant was used in the majority of in-home air conditioning systems and considered the king of refrigeration. Well, the times have certainly changed.

Since January 2020, the production and importation of R22 has been banned, allowing only for continuing use of R22 from recycled or stockpiled reserves because of its negative impact on the environment. By January 2030, the EPA’s goal is to phase out the use of R22 almost entirely

Considering that the majority of air conditioning and other cooling systems manufactured and installed before 2010, when heavy R22 regulations began, utilize R22 refrigerant, these mandates have changed much about the education and practices of HVAC technicians when it comes to refrigerants. 

It has spurred us in the HVAC industry to explore and understand more environmentally and efficient refrigerant alternatives as well as inspired technicians to educate their customers on the matter. After all, the phasing out of R22 refrigerant is also going to put customers in the position to make some important decisions regarding their systems as well. 

When those questions and decisions do come up, as an HVAC technician or a technician in training it’ll be your responsibility to help your customers make the best and most informed decisions for understanding and replacing their R22 refrigerant systems.

Here are some of the most important things for you and your customers to understand about R22 refrigerant.

Why R22 refrigerant is banned

The reason refrigerant has fallen under so much scrutiny over the past few decades is the negative impact it has been found to have on the environment. Refrigerants can produce emissions that are destructive to the Earth’s ozone layer and contribute to global warming. 

This revelation spurred the EPA and governments across the world to begin enforcing stricter regulations on the use of refrigerants and creating new required certifications for HVAC technicians on the handling and disposal of refrigerant, such as the EPA 608 Certification.

So, while 2020 was a year that ramped up restrictions on production and importing of R22 refrigerant, regulations on environmentally harmful refrigerant has been ongoing for decades, with 2010 being a major turning point. 

Your customers can continue to use their equipment

The most common question you are likely to encounter from your customers regarding their R22 refrigerant units is “am I still allowed to use it?” The answer is, of course, yes. While the ban exists to cease the production and import of R22, it doesn’t ban the ongoing use of it. So, it is important to put your customer’s mind at ease on this fact.

However, while the ongoing use of their current system is fine, it will present some serious issues for them going forward. As their HVAC technician, someone they should value and trust as an expert in your field, you do have an obligation to inform your customers of what they will be dealing with long term with these systems.

Maintaining their R22 refrigerant system is going to cost them

Because of the ban in production and import, ongoing repairs and replacements on R22 refrigerant systems will have to come from the remaining stockpile of reserves – a stockpile that will continue to rapidly dwindle over the next few years.

As supply diminishes and repair and maintenance demand for these systems (many of which installed before 2010) increases, it will create a landscape in which the cost of these repairs will rise and rise and rise. In the next few years, a refrigerant replacement job that would normally be fairly straightforward and relatively inexpensive will cost your customers a great deal more because of the limited supply.

As you encounter customers with cooling systems that utilize R22, it is a good idea to make this situation known to them and help them understand their options going forward. They may be stubborn and OK with paying more for the sake of living with their system until it finally kicks the bucket. However, you should make them at least understand the value of upgrading and replacing their cooling systems with more efficient and environmentally friendly modern systems.

R22 alternatives

As HVAC technicians continue to work in a post-R22 world, knowing the available R22 alternatives will help you be a better and more well-rounded HVAC technician, as well as become a more valuable resource for your customers when they are searching for replacements for their outdated cooling systems.

While no refrigerant is perfect and each has their own pluses and minuses, our preferred R22 alternative is R421a. R421a has 0 ODP, is non-flammable, is useful in a number of different applications, can in many cases can be used as a direct R22 replacement, and most importantly is one of the more environmentally friendly refrigerants available. 

R32, R407c, and other greener refrigerant alternatives are also available and preferred by some. Like we said, there is no end-all be-all refrigerant choice. Good HVAC technicians will familiarize themselves with as many as they can and come to their own conclusions as to which they prefer and recommend to their customers.

The Training Center of Heating and Air Conditioning takes the health of the beautiful world around us very seriously, so refrigerant education is something we take very seriously and even make EPA 608 certification a part of the requirements for graduation from our school.

Common Electrical Terms You Need to Know

Common Electrical Terms You Need to Know

The beautiful thing about beginning your career as an HVAC technician is that you don’t need any previous experience or knowledge. At the Training Center for Heating and Air Conditioning, our classes cover the absolute basics, so students of all knowledge levels can be on equal footing. All you need is a good work ethic and a willingness to learn.

That being said, for anybody considering education and training in heating and cooling can certainly benefit from familiarizing themselves with some important elements of working in HVAC. 

One of the most important things to understand during your HVAC training is the language and terminology. HVAC installation and repair incorporates many common electrical terms that you may have heard before or run into during previous science classes in school. Understanding these terms is crucial for HVAC technicians and beginning your education with knowledge of them can get you started off on the right foot.

Here are some common electrical terms HVAC technicians need to be familiar with and what they mean. Each of these terms relates to different materials and parts of a heating or cooling system that relate to the transfer of electricity. 

Conductor

An electrical conductor is any kind of material that allows electricity to flow easily through it with little to no resistance. Certain metals like copper, aluminum, silver, and gold are all terrific conductors of electricity. This is why many of the wires used in HVAC equipment are made of these materials. This is also a great reason why practicing extreme safety precautions when working with live wires.

Resistor

An electrical resistor is any material or component in the electrical circuit that resists the flow of electricity, limiting the amount of electricity that passes through them at any given time. Resistors are important because without them limiting electrical flow to motors, coils, lights, and heat elements, these components would become overloaded with electricity and more quickly burn out or overload causing a loss of efficiency and creating potential hazards.

Capacitor

An electrical capacitor stores electricity for short periods. Many HVAC systems have dual capacitors, a start capacitor and a run capacitor. The start capacitor provides the electrical power needed to get the compressor or fan motor of the heating and cooling system started up. The run capacitor, on the other hand, in turn, supplies the compressor or motor the energy it requires to keep them running.

Insulator

An electrical insulator is a material or component of a heating and cooling system that does not allow electricity to flow through it. Wires and thermal pipes in an HVAC system are equipped with insulating coverings to prevent the loss of energy and heat so the unit can run more efficiently.

Now don’t think that knowing the meaning of these common electrical terms makes you an expert. There are still plenty of other important terms you’ll need to know as you continue your HVAC education. However, for folks looking to start their journey without much past experience, understanding these terms can get you off to a good start.

4 Things HVAC Technicians Get Wrong During AC Installation

4 Things HVAC Technicians Get Wrong During AC Installation

Being an HVAC technician involves a lot of very technical and precise work, particularly when it comes to AC installation. This is why a proper education and training is so important for a long and successful career in the industry. 

Unfortunately, not all technicians get things right during AC installations. In fact, there are a few practices that HVAC technicians actually get wrong more often than not. Why is that? It could be many things from displacency to simply not receiving proper education.

So, why is it important to talk about the shortcomings of AC technicians? In such a precise field that so many people rely on for their important service, these shortcomings are unacceptable. For those that are considering pursuing a career as a certified HVAC technician it is just as important to know the wrong way as the right way. 

As an HVAC professional, you want to strive to provide the best care and service to your customers that depend on you to stay safe and cool. Knowing where others in the industry fall short can help you know where you can avoid the same pitfalls and become a more successful AC technician. 

Keep in mind these common mistakes that HVAC technicians make during AC installation. You’ll notice the biggest pattern that emerges from these improper installation missteps is that they each can have serious negative impacts on the performance, efficiency, and lifespan of the air conditioning unit.

70% of technicians don’t follow proper vacuum procedures

One of the most important things technicians ignore not following proper AC vacuum procedures during installation. Vacuuming is important because it helps remove any excess moisture left within the system. Over time, moisture build up can cause long term damage from poor performance, corrosion, and even freezing with the AC system. Never skip this important step in the post-installation process. 

70% of technicians don’t adjust for proper air flow

Ensuring an air conditioner has been adjusted for proper air flow ensures that it can efficiently and easily keep in-home air cool and comfortable for the customer. Proper air flow lets air more easily reach all the nooks and crannies, ensuring no random hot spots. When not adjusted properly, the system has a harder time performing and has to put in extra effort to keep the home cool, which not only can shoot up a customer’s utility bill but also causes AC’s to burn out faster than they should.

70% of technicians don’t charge unit per manufacturer recommendations

Correctly charging your customer’s AC system will ensure there is proper refrigeration to pull out hot air and keep their home cool. However, despite the fact that most manufacturers provide step-by-step instructions and offer their best practice recommendations, this correctly charging units often gets overlooked. The result is either an undercharged unit that can’t keep up with the heat and overwork itself or an overcharged unit that is loud and draws far more energy than it needs to.

90% of air conditioning installations are incorrect

Since these three steps during AC installations are so important, it may not be surprising to hear that more installations are done incorrectly than not. But, for an industry that prides itself on hard workers and providing a necessary service to its customers, this is a number that simply cannot continue to last.

Here at the Training Center for Air Conditioning and Heating, we are attempting to lower the statistics through a comprehensive training and education program for the next generation of HVAC technicians. The course is designed to teach students the skills and techniques required for entry-level employment into the residential and light commercial heating ventilating and air conditioning so that they can not just install and repair heating and cooling systems, but do it the right way to better serve their customers and help make them a more successful professional.
