Different Types of HVAC Units

You might not have given the types of HVAC units available much thought when installing one in your home. However, each unit has its own benefits and drawbacks. If you plan on installing an HVAC unit, it is worth taking a second look at the four basic types of HVAC units available. 

Heating and Cooling Split Systems

Heating and Cooling Split Systems are the most common types of HVAC systems. The system is split between two main units, one for heating and one for cooling. Hence the name “split system.”

These units contain both an indoor and outdoor component. Do you know that large box you see blowing out air on the side of homes? That is the outdoor piece, also known as the condensing unit. This cooling system outside using refrigerant, compressors, and coils to cool air, and a fan to blow out hot air.

This system uses a traditional thermostat to manage the temperature. Because of this, the system is able to keep most houses at a desirable temperature. These systems are most widely used because they are most generally applicable. These units do not require any specific needs or environmental factors. This makes them perfect for most homes.

Hybrid Split System

A hybrid system is similar to the split system, but with some key differences. These systems are on the rise due to their ability to mitigate energy costs through their electric hybrid heating system. This differentiates them from other types of HVAC systems.

The ability to switch between gas power to electric power allows homeowners to decide how they want to heat their homes. Gas power is much quicker and more complete than electric, but electric power is more efficient and quieter. This system uses traditional ducts, as well as thermostats, and provides all the benefits of a split system, but with the added option to conserve energy. Plus, these units can lessen utility bills.

Duct Free

A duct-free system, also known as a mini-split system, provides big benefits for certain needs. However, these systems typically have large upfront costs. These HVAC units are individual units in each room. These units are perfect for new additions to homes, such as garages, additions, or additional buildings, because it is easier to install. Plus, this system allows independent control over each unit. These types of HVAC units are also beneficial for service businesses such as hotels or venues, allowing tenants to control individual temperatures. 

Another benefit is energy conservation since individual rooms that are being used are being heated, it keeps exterior or unused rooms from wasting energy. The small size of a ductless cooling system and its zoning capabilities allows for greater energy efficiency.

Despite the benefits, these systems require regular and intensive cleaning and maintenance. This is important to keep up with as the cost of total repairs and replacements are quite expensive. 

Packaged Heating and Air

Packaged heating and air is the most niche unit. This system is typically stored within the house and is usually kept in an attic or top storage place. It serves to both cool and heat a home.

Its compact size makes it useful for smaller spaces or houses. Its size allows it to be placed within the home if the exterior is not an option. Despite its size, this type of unit is able to be very efficient and easily maintained. These units are typically used in warmer climates since the heating element is not as strong as other systems. 

There are many types of heating and cooling systems, but now we hope you are a little more prepared to make a decision. These types of systems are just a fraction of the things you will learn about during your time here at the Training Center of Air Conditioning & Heating in Houston, Texas.

How to Interview for an HVAC Job

How to Interview for an HVAC Job

Now that you’ve graduated from an accredited school, it is time to begin the HVAC interview process for a job in the industry. When interviewing for a job in the industry, there are few things you can do to increase your chances of landing a job. Use these tips to prepare for your interview, impress your potential employer, and land the job.

Bring Your Resume

Never assume your interviewer has already seen your credentials. Always bring a hard copy of your resume with you to HVAC interviews even if you already submitted your resume or filled one out online. It is good practice to have your resume on hand when you walk into an interview. This shows that you are fully prepared and capable of thinking ahead.

If you are wondering how to impress your interviewer with your resume, consider making some changes to it. A good resume should include the following:

  • Employment history
  • Education history
  • A list of EPA and other certifications
  • Related skills
  • References
  • Contact information

Learn About the Company

Not only will learning about the company impress your potential employer but researching the company will also help you prepare for the HVAC interview. Begin with the actual job description. This will provide you with an understanding of what the company is looking for in an employee. 

Be sure to visit the company’s website to learn more about their mission statement and values. Plus, check out the services the company offers. When speaking to the interviewer, make sure you mentioned your experience and expertise as it relates to these services. 

Be Prepared to Demonstrate Your Knowledge

In addition to generic interview questions, you will be asked specific questions about the HVAC industry. Be ready to answer questions about different kinds of equipment and challenges you may face as an HVAC technician. Even during a first interview, many HVAC employers will ask a few questions about the kinds of equipment and challenges you might encounter. Being as detailed as possible can help you demonstrate your knowledge of a particular piece of equipment or challenge. 

Before the interview, have someone ask you sample questions so you can prepare in advance. Learning the possible questions before the interview and preparing an answer beforehand will help you appear knowledgeable. Plus, you will feel much more comfortable during the HVAC interview.

After the HVAC Interview

Once the interview is over, be sure to send the interviewer a thank-you note, even if you do not land the job. Whether you think you aced the interview or bombed it, always follow up with a friendly message expressing your continued interest in the position and the company. This gesture will make you stand out from the other applicants which will help you secure a position in the future. 

Before beginning the HVAC interview process, the first step in securing a job in the HVAC industry is a quality education. When you are ready, do not hesitate to contact us at the Training Center of Air Conditioning & Heating here in Houston, Texas.

HVAC Technicians Can’t Rely On “Beer Can Cold”

HVAC Technicians Can’t Rely On “Beer Can Cold”

If you have spent any time around HVAC, either in a classroom or just chatting up an HVAC technician, there is a decent chance you’ve heard the expression “beer can cold.” “Beer can cold” is an expression that originated in the early days of air conditioning, back in the ‘50s and ‘60s. It was created to describe the temperature at which an air conditioning system has been properly charged with refrigerant. 

The idea is if you were to grab a properly charged suction line it would be as cold as a cold beer can. It is also a completely irrelevant, incorrect, and outdated expression that shouldn’t be applied anywhere near modern-day HVAC. In fact, if you ever hear a fellow HVAC technician using that term earnestly turn the other direction and run away.

“Beer can cold” is an expression that no longer holds any relevance for HVAC technicians and should be left in the past. If you are an HVAC technician or in training to become one, here are three reasons to forget everything you may know about “beer can cold.”  

What is “beer can cold” anyway?

One of the biggest arguments against “beer can cold” is that in a very precise industry this kind of measurement is not even remotely precise. What is the exact temperature of “beer can cold?” You can technically drink beer at any range of cold temperatures and different folks may have a different take on what the ideal temperature of a cold beer is. 

Also, a beer out of a cooler full of ice maybe 32 degrees and one out of the fridge maybe 35 to 38 degrees, but they feel relatively the same to the touch. Air conditioners today are manufactured with distinct specifications on charging temperatures, and the tools HVAC technicians have at our disposal today make taking accurate temperatures much simpler than relying on getting a relative temperature by hand.    

“Beer can cold” is misleading

Extremely hot working conditions are very common for HVAC technicians, especially here in Houston. If you were to grab a suction line that is about 50 degrees on a 100-degree day outside, that suction line is going to feel extraordinarily cold even though it is only 50 degrees. Now, if you grab that same suction line when it is only 60 degrees outside, it is not going to feel anywhere near as cold. Also, if there is a lot of moisture in the air, the suction line will be wet and feel colder than a dry line at the same temperature.

Aside from not having an exact reading for “beer can cold,” taking a temperature by hand can lead to horribly inaccurate and misleading readings that can lead to serious errors during installation and repair. Using this method on the job will likely cause you to make serious mistakes.

It’s not the ‘50s anymore

The truth about “Beer can cold” is that even though it is an expression that began in the ‘50s, it was an outdated expression even back then. So much about air conditioning in the past 60 years. Back then, compressors were oversized, coils had a lot of extra space, and fan motors were higher in horsepower. Flexibility in the charging of refrigerants was not a significant issue since a pound over or under would not cause any drastic changes.

Today’s air conditioning units are built much differently. Units are built to be just big enough, their coils are not oversized and their compressors are barely large enough. This all makes the efficiency rating of units higher, but also means the charge of refrigerant has to be within 2 ounces of the correct amount. Unlike the old days, air conditioners require a much higher level of precision. 

The mantra of “beer can cold” is not only outdated, it was truthfully never a helpful or accurate reading to begin with. Here at the Training Center of Heating and Air Conditioning, we teach our students how to use the advanced techniques and tools at their disposal to do the job and charge the air conditioners they work on the right way, leaving “beer can cool” where it belongs: In your hands after a hard day’s work and you are relaxing at home in your hammock.

The World Needs HVAC Technicians More Than Ever

The World Needs HVAC Technicians More Than Ever

The coronavirus pandemic has put our country in an unprecedented position and put us all face-to-face with many hardships. It has been a tough time for all of us, but it has also been an opportunity for people across the country to rally together to prove that we are all in it together.

As the country continues to work towards going back to normal, everyone is doing their part to stay safe and keep others safe. Heroes of all shapes and sizes have stepped up to provide extraordinarily important services. It has also shown that now, more than ever, the world needs capable and talented individuals as HVAC technicians.

People are spending more time at home

The unfortunate truth with the coronavirus is that in order to beat it we will all need to do our part practicing safe social distancing. And while we all want things to go back to normal, this will mean more time spent at home for the foreseeable future, unfortunate as it may be. 

As we adjust to a future with increased time spent at home, people won’t have the luxury of giving their air conditioning and heating a rest from time to time. During the dog days of summer, folks will need to keep their AC running full blast in order to keep their family comfortable. With less going out, folks will also be at home breathing the same old air.

Now, more than ever, people will need the help of qualified HVAC technicians to keep their homes comfortable, safe, and their heating and cooling equipment running strong. The extra running of cooling and heating equipment can cause them to wear out and require additional maintenance and checkups. Staying indoors will require folks to take advantage of duct cleaning services as well to ensure their in-home air stays clean and allergen-free.

Without trained HVAC technicians ready to lend their services to those in need, folks doing their part to maintain social distancing and protect themselves and others will be looking at a very uncomfortable summer, fall, and winter to come. 

The shortage of skilled workers continues

On top of the need for HVAC technicians to take care of those at home, the country is still experiencing a great shortage of skilled workers in the HVAC industry that has been ongoing for the past several years. 

This shortage has been created in part to the gap between professionals leaving the business and new technicians joining the industry. There has also been a significant applicant pool shrinkage as school budget cuts eliminate programs like shop class and many students have chosen to more aggressively pursue traditional, 4-year educational programs.

For those with an interest and aptitude for HVAC training, however, there has never been a better time to begin one’s career and education in this extremely rewarding industry. There is not only a wealth of positions available for HVAC technicians, there is an equally large need for professionals to fill those positions and eagerly awaiting customers. 

Heroes are appearing in all shapes and sizes through the COVID-19 pandemic, and there is a great need for heroes in the HVAC industry. If you live in the Houston area and are considering a rewarding career as an HVAC technician, there really and truly has never been a better time to start your education.

The Training Center of Air Conditioning and Heating offers three new training classes each year with flexible morning and evening training sessions. Learn more about our training program and enroll in our upcoming fall and winter classes today.

But, as the demand for HVAC technicians during this time has increased, so has demand for our training courses. Availability is limited, so register today and save your spot!

 

How HVAC Pros Should Deal with Difficult Customers

How HVAC Pros Should Deal with Difficult Customers

Over the course of doing their job, HVAC technicians, like other professionals in the home service industry, have the unfortunate task of dealing with difficult customers. While that isn’t unusual for professionals in other fields of work, there are a few reasons why it can happen so frequently for home service professionals.

Perhaps the most relevant reason why is that HVAC technicians rarely interact with a customer when they are having a wonderful day. The entire reason you are there is that they are in a difficult situation, either something is wrong with their heating or cooling system and they are super hot, cold, or uncomfortable making them agitated or unhappy before you even arrive. 

In addition, because of your service, they are likely looking at a somewhat sizable bill. While HVAC technicians provide an important service, they aren’t always the bearers of great news. Unhappy customers may feel more inclined to voice their displeasure because they are in their own home as well, especially if they’ve had a poor experience in the past. 

Combine all the factors that can make a customer unhappy along with any feeling they may get that they received poor service or the job wasn’t performed to their liking and you’ll likely find yourself with a difficult customer.

While you may or may not be at fault, dealing with a difficult customer isn’t fun. But if you do, use these helpful tips to help defuse the situation and find the best resolution possible.

Stay cool

If an unhappy customer gets nasty with you, especially if you are in a hot and humid house, it can be easy to lose your temper and get nasty right back. This is the absolute worst-case scenario. If you lose your cool with a customer, it is only going to get uglier, there isn’t likely to be any positive resolution, and the customer is likely to take the complaint up the chain of command and get you in even deeper trouble.

But, if you manage to keep your cool and keep your emotions out of it you will be able to focus on how to deal with the problem and not simply get emotional about the situation. If you are able to speak clearly and calmly, the customer may be encouraged to calm down and follow your lead. Then, once both parties are calm you can focus on finding a solution. 

Hear them out

While the service industry saying goes “the customer is always right,” sometimes they simply aren’t. They may indeed have the situation all wrong, be upset and directing their anger about something outside of your power at you, or simply just being altogether difficult. No matter how wrong they may be or how nasty they are about the situation, at least hear them out.

By listening to the customer instead of trying to correct them, talk over them, or argue with them, you can start building rapport with them. It demonstrates to them that you are paying attention to their concerns and listening to them are actively trying to understand and get to the root of the problem. By actively listening and repeating and acknowledging their concerns, your level of care about your job and the situation becomes apparent.

Don’t make promises you can’t keep

While it is important to take the concerns of a difficult customer seriously and to do everything in your power to resolve the situation to their satisfaction, it is also important to realize that the issue may be something outside of your control or something you simply can’t resolve right then and there. For that reason, tell them you will do everything you can to fix the problem but never make a promise you know you can’t keep.

Making and breaking a promise to a customer is a bad road you don’t want to go down. When you break a promise with an already angry customer they feel betrayed and will only flare tempers even more. It also puts you in the unfortunate position of having to backtrack and most likely need to apologize.

It’s OK to fire a customer

Sometimes there’s just no winning with a customer. If a customer is getting downright unpleasant and it is obvious that there is no pleasing them. In the end, you are just going to sink excessive time and energy into them and not see a dime. We call these kinds of clients “tire kickers” and sometimes it is OK to simply fire them.

You hear it all the time from the other perspective, a customer firing their service provider, but it can work the other way too. If you reach a point where the unpleasantness of a customer is too great to handle, refusing to offer your services is a viable, albeit fairly drastic, option.

Don’t take the argument online

If a situation isn’t 100% resolved by the time you leave or you are put in a position where you have to fire a customer, it is a good possibility that they may try and take their complaints to the internet, leaving a negative review or comment. How a home service professional handles themselves online is just as important as how they handle themselves in person, so it is important that you handle negative reviews carefully.

First of all, treat every review respectfully and don’t continue whatever disagreement you may have had in-person online. When you argue with a customer online, you air your dirty laundry in front of anyone who cares to look and can only serve to drive away potential customers. But, if your response is cordial, calm, and inviting for them to contact you directly to once more try and resolve the issue, potential customers will see that as well and see your positive reaction to difficult situations.

Customer service skills are one of the most important skills HVAC technicians need to have in their toolbox, along with the knowledge and skills to repair and install heating and cooling systems of course. Having a thorough understanding of how to provide customer service and deal with difficult customers can help any technician succeed.

Communication and customer service are two areas we focus deeply on during our course here at the Training Center of Air Conditioning and Heating as we prepare up and coming Houston HVAC technicians dealing with difficult customers. Contact us to learn more about our classes and enrollment.
