Common Air Conditioning Installation Violations and How to Avoid Them

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.

10 Questions to Prepare for During an HVAC Job Interview

10 Questions to Prepare for During an HVAC Job Interview

When you’re looking for employment as a certified HVAC technician, it’s important to prepare yourself for job interviews. 

To fully show your skills to potential employers, you need to be able to communicate about them. 

HVAC companies want to make sure that they are hiring the right people for the kinds of jobs and customers they have. They’re looking for technical training as well as “soft skills” like customer service, time management, clear communication, and more. 

That’s why it’s important to prepare yourself to be able to confidently answer questions about yourself, potential clients, your work process, and the company you’re interviewing for.

It can be a lot to keep track of, but we don’t want you to overthink it. 

Here are 10 baseline questions you should prepare for during an HVAC job interview to set you up for success in your new job. 

 

General Questions

Most job interviews begin with general questions, becoming more specific and technical as the process moves forward. 

There might not necessarily be any right or wrong answers to the more general questions, but the way you answer them could make or break the interview. Essentially, they want to know if your personality and work ethic are a good fit for their organization.

Some general questions you should be ready to answer are: 

  1. Why do you want to work in HVAC?
  2. What do you know/how did you hear about our company? 
  3. What types of repair and maintenance projects have you worked on?
  4. What are some skills you’ve gained from other jobs that have helped prepare you for this position?
  5. How do you define success at work and in general?

The way you answer these questions shows your interest and attitude towards your career. 

Employers often care more about your willingness to learn and develop as a professional rather than the experience you might have. 

This is especially important to keep in mind if you recently graduated from HVAC school. Make sure your employer knows how passionate you are about what you do and how much growth you will bring to the company. 

 

In-Depth and Technical Questions

Even though your personality and professionalism help set you apart, you still need to communicate your mastery over what you do. 

It’s important to be honest about what you know, what you’re capable of, and what you feel confident to execute. 

Remember, you can always learn more on the job. If you show you’re a good fit for the team and that you’re committed to learning, companies will invest in you even if you have less experience. 

Keeping that in mind, here are some technical questions you’ll likely be asked: 

1. How do you stay informed regarding the latest developments in the HVAC field?

Employers want to know if you’re ready to take care of customers and provide them with expert service.

Being able to answer questions like this demonstrates you’re committed to learning and shows how you’re going to help bring new ideas and perspectives to the team. 

Once again, honesty takes precedence over everything else. If you could do more to further your education, ask them for some good resources they’ve heard of. This will show even more of your desire to learn and grow.  

2. Can you tell me how the acronyms BTU/CAV/AHU apply to HVAC work? 

In the HVAC field, there are lots of acronyms. During your training and education, you’ll learn about these and know them like the back of your hand.

Employers will ask about technical terms like these to see if you’re able to talk about HVAC as someone who’s committed to the industry knowledge, not just someone who does the work. 

3. Tell me about a dispute between you and another employee/supervisor in a previous job. How did you handle it and keep the job moving forward?

These questions may make you feel a bit on edge, but it’s important that you demonstrate your commitment to professionalism. 

Employers don’t ask about disputes to put you on the spot; they just want to know how you can address team issues while still getting the work done and maintaining good levels of service.  

So, be honest and show that you can do just that. 

4. Tell me about a challenging technical situation you had during HVAC work or training. How did you overcome it?

Employers ask questions like these to learn more about your technical knowledge, but also about your process for solving problems. 

They want to know if how you operate will make you a good fit for the team. Employers are looking for teamwork and leadership skills, on-the-spot thinking, resourcefulness, and other traits that go beyond your job description. 

5. Customer scenario questions: what would you do if________?

There’s no definitive way to prepare for all scenario questions. The most important thing you can do is answer how you would on the job site—as a professional. 

Employers are looking for how you’ll react when customers ask about environmental concerns, repair times, pricing, safety, and many other things. 

They want to see how you can provide information, address problems, and communicate with team members to keep things moving forward safely and professionally.

There is a demand for HVAC professionals

A combination of a long-standing labor shortage in the skilled trades workforce along with the labor shortage created in part by the coronavirus pandemic means there is a need for HVAC professionals across the United States now more than ever. 

That demand is particularly being felt right here in Texas especially as we hit the peak of summer. Folks in Texas need their cooling equipment cared for, but there is a lack of skilled labor to serve them.

Coupled with the large amounts of job opportunities, the demand for labor in Texas means that once you complete your necessary training you have a good chance of securing a good-paying job right out of the gate. There are jobs available in Texas, and heating and cooling companies are willing to pay. Enough said!

Cooling is particularly valuable in Texas

Don’t get us wrong: properly working cooling systems are greatly appreciated all across the country. However, no one appreciates them quite as much as Texans. During summers in Texas, we can average highs in the upper 90’s every single day for months at a time. It gets so hot in Texas that the design temperature of HVAC systems has to be set for the 100’s in many of our state’s counties.

In some parts of the country, HVAC companies are at the mercy of the weather. Mild summers mean people can get by with what they have, which can affect their bottom lines significantly. Not here in Texas. Even a mild Texas summer can be brutally hot, meaning there will be plenty of work available each year.

We love Texas, but boy can it get hot! However, that means that Texans are especially appreciative of their HVAC service professionals. When it gets really, really hot lives are literally at stake. People won’t overlook the value of the service you provide to them.

Expert training available

Because of how important HVAC professionals are here in Texas, getting the proper training is of the utmost importance. This is why here at The Training Center of Air Conditioning and Heating we are proud to provide the best HVAC training in Texas to best prepare students for the demands they will face.

Our school’s founder, Chris Walters, has been in the heating and cooling industry right here in Texas for over 30 years.

Should HVAC Trainees Be Worried About the Material Shortage?

Should HVAC Trainees Be Worried About the Material Shortage?

Even though the COVID-19 pandemic is slowly going away as more folks receive their vaccines, the world is currently dealing with another crisis in the form of the material shortage that is greatly impacting many businesses and industries. The HVAC industry is one that has been particularly affected.

Dealing with this material shortage has put a lot of pressure on the HVAC industry and HVAC professionals. The shortage has created significant difficulties in producing and acquiring important heating and cooling equipment, delaying installations and projects. 

These pressures have frustrated both professionals and customers alike, making the landscape for incoming HVAC professionals uncertain. With a material shortage affecting the job they do and the services provided, should incoming HVAC professionals and those just beginning their education and training be concerned about the heating and cooling material shortage?

While this shortage is definitely something that heating and cooling professionals need to educate themselves on, fully understand, and account for, it should certainly not be something that should dissuade individuals from a rewarding and important career.

Why is there a material shortage?

First things first, why is there a material shortage to begin with? It is the result of a domino effect tipped off by the coronavirus pandemic. When the pandemic first hit and lockdowns were ordered across the world, manufacturers had to adjust. Many severely scaled back production, some had to lay off a large portion of their workforce, others had to shut their doors entirely.

During this time, the production of materials was limited which meant available inventory was quickly used up without being able to be replaced. That brings us to today. As the world continues to return more and more to normal, demand has ramped back up but that demand is not able to be kept up with due to still-limited labor forces and an almost non-existing inventory.

For HVAC, construction materials, as well as microchips used in smart heating and cooling systems like programmable thermostats, have been the items most drastically affected. Hardships obtaining these materials means HVAC manufacturers have been producing them at a slower rate.

This material shortage WILL end

All indicators are that this material shortage is something that will loom over manufacturers and affect businesses and industries for an extended period of time. However, as difficult of a crisis to navigate as this material shortage is, experts also continue to indicate that it isn’t permanent and it will eventually even out.

Microchip shortages, of particular relevance to the HVAC industry, are predicted to start slowly dwindling over the next two years. While this may still seem like a bit of time, considering the severity of the crisis, the fact that an endpoint is already in sight is a great indicator.

Other materials will follow the same trajectory, some sooner than others, and sooner or later things will return back to normal for the HVAC industry. Until then, your customer service skills as an HVAC professional will be of great importance as you help your customers understand and plan to work around the material shortage.

Set realistic expectations

Some of your customers may be so far removed from the material shortages impacting different businesses and not completely understand why their orders are taking so long to be fulfilled. As a heating and cooling expert, it will be up to you to help educate your customers.

Delays in new equipment installation will undoubtedly cause some frustration with your customers, so the best thing you can do to prepare them is to be transparent about the crisis and set realistic expectations for their projects.

Communication skills are an undervalued soft skill for heating and cooling installers and technicians and navigating the material shortage crisis will require everyone to be at their best. 

Customers will still be counting on you

One of the biggest reasons why incoming HVAC professionals shouldn’t be discouraged by the material shortage is one simple fact: despite issues producing HVAC products, homeowners and business owners are going to continue to depend on the valuable service that those in the industry provide.

The summers aren’t going to suddenly stop being hot and the winters are not going to suddenly stop being cold. Across the country, the demand for HVAC maintenance, service, and new installation is not going to stop just because equipment is harder to come by. The world still needs hardworking and skilled professionals to put their skill set to work protecting their homes and businesses. 

In fact, in addition to the material shortage, there is a similar labor shortage happening across many industries. This is of course nothing new to the skilled trades, which have been experiencing a need for labor for many years leading up to the pandemic. 

Don’t be intimidated by the material shortage. There is still a need for services and there is a need for professionals like you!
