When you replace an old HVAC unit with a new one, there are certain things worth keeping in mind. For example, many people tend to only replace their HVAC unit on rare occasions. However, having those units replaced in regular intervals can ensure that their HVAC unit is keeping them safe, healthy, and sufficiently heated and cooled. Some homeowners may also want a new unit to help them save on energy. With the right tools and knowledge, you can complete an HVAC replacement job that accomplishes each of these things.

Although replacing an HVAC unit involves a number of steps to complete before, during, and after the installation, these are some of the more important phases to remember during this process. Read on to find out what you can expect with regards to replacing HVAC units.

Preliminary Measures for HVAC Technician Training Students to Remember

Before the replacement process can begin, there are certain tasks to take care of. For one, you’ll need to assess both the home and the old HVAC system, and complete the necessary calculations and measurements. Once this has finished, you can determine how big the new HVAC system needs to be. Measure the square footage of the home to better understand how big the new unit will need to be, and how many tons of heat it can remove. You and the client will also need to determine how they will pay for the installation. Depending on the payment plan, they may put a down payment on the replacement prior to the installation. 

Upon completing your cost estimate, replacing the HVAC unit can go ahead. Complete a ductwork inspection, if necessary, and disconnect the unit being replaced after powering it off. If any parts of the interior, such as furniture, are impeding your ability to get the job done, move them away from your working area. Since HVAC technician training students will learn about installing many different types of systems during their studies, it’s equally important that they learn what’s necessary for the pre-installation phase.

The Installation Process: Out With the Old, In With the New

Once these tasks have been completed, the installation of the HVAC unit replacement can begin. When installing, remember to use dust covers and wear protective gear to prevent any direct contact with debris. Even if only one component of the HVAC unit needs to be replaced, you should still replace the entire unit so that its capacity for efficiency is optimal. Be sure to also cut off power from the old HVAC unit, flush any remaining coolant, take apart the old equipment, and then remove those parts to make room for new ones. The HVAC unit replacement can often be done within the day of installation, but can sometimes go beyond that if complications arise.

Students in HVAC college should also familiarize themselves with the parts that will be involved in the replacement. These parts include the outside compressor, thermostats, evaporators, air handlers, condensate pumps, and/or supply lines for coolant. Once the installation process is done, remember to put the new unit through a series of tests to make sure it works correctly and can sufficiently cool the home. Inspect the system to catch any possible issues, then add a new coolant and keep testing the unit until all systems look good. Lastly, remember to discard and/or recycle any old HVAC equipment being replaced. Explain to clients how the new system works, and recommend a timeline for their next replacement.

There’s nothing worse than the AC breaking down on a blazing hot day—apart from maybe the heating system fizzling out when it’s a frigid -30 degrees! HVAC technicians become very popular individuals at the height of summer and winter, serving to rescue home and business owners from uncomfortable temperatures by performing emergency repairs as they come up.

Keeping HVAC units in good working order through routine checkups is another important role of the technician. Here’s why routine maintenance practices are important for keeping these systems in their best shape all year round!

Routine Maintenance Helps Owners Breathe Easier

Respiratory problems like asthma and bronchitis can often be traced back to the living conditions of the home, with the dirty HVAC unit a prime culprit in many cases. The problem comes from condensation forming in the coils and ducts of the AC unit, which can lead to all kinds of harmful mold and bacteria growth.

Customers who keep to a routine maintenance schedule for their HVAC units are ensuring that all of the harmful contaminants that may have built up inside the system are eliminated. A service technician is responsible for cleaning filters, coils, and other components of the unit on a routine visit, which leads to a cleaner unit, thereby improving air quality.

A Well-Maintained System Can Save the Owner Money

What would a home or business owner care more about than breathing clean air? How about more money in the old pocketbook! If you’re interested in HVAC technician training, you should know that keeping an HVAC system in good working order can help the owner save money by optimizing efficiency to keep energy costs down. A well-maintained HVAC system uses a lot less energy and puts less wear and tear on the machinery of the HVAC unit, running a good 20% more efficiently than a neglected unit. 

Regular checkups in the fall and spring can keep efficiency strong, and help an owner get a good ten years out of their HVAC investment. Routine checkups also allow the service tech to catch a small problem needing a quick, inexpensive fix before it turns into a much more complicated problem requiring lots of work—and lots of coin to repair. 

Fewer Emergency Breakdowns and More Warranty Opportunities

People run their HVAC systems pretty hard in the summer and winter months, which can lead to breakdowns. These machines are designed to handle the energy levels the owner demands, but only if the unit is being looked after properly. If you’re seeking your HVAC diploma, you should know that breakdown prevention during the hottest and coldest times of the year is reliant on keeping routine maintenance and inspection checks. 

By keeping up regular twice-a-year visits, the owner may even be lucky enough to discover that a part that needs work or full replacement is still under warranty. Longer waiting times between visits reduce the opportunity to spot a problem before a warranty period has reached its expiration date. 

What Are Some Maintenance Tasks Those Attending HVAC School Should Know About?

There are a few things to watch out for during routine maintenance checks. On heating systems, the tech will need to check: fuel lines and power sources, inspect combustion chambers, inspect the heat exchanger for cracks or other evidence of damage, as well as check for carbon monoxide leaks.

On cooling systems, the tech needs to take a look at the fans and blowers, thermostat, system controls, ductwork systems, evaporator and condenser coils, and condensate drains to ensure everything is clean, undamaged, and functioning properly. Additionally, fans and motors must be lubricated, and refrigerant levels must be filled.

All of these tasks need to be performed at regular intervals to ensure that systems keep running properly.

It’s not just the quality of an HVAC unit that counts, but how it’s installed. As an HVAC technician, your responsibility is to install these systems and detect any issues that can arise within their many different components and figure out how to correct them. However, there are several mistakes you can find yourself making if you aren’t careful with the installation process.

Since learning how to maintain and install HVAC systems are a significant component of your job, it’s just as important to know what not to do as it is to learn best installation practices. Here are some of the more common mistakes you may find yourself making after your HVAC training.

Ductwork is One of the Most Important Factors to Watch After HVAC School

It’s important to be sure you choose the correctly-sized duct for the HVAC unit you’re installing, and use high-quality materials in the process (e.g. using a heavy-duty sealant instead of tape, and adding R-6 insulation wrap).

If you don’t, it can create issues with both air flow and leaking, and potentially result in gaps, dust, loud noises, or an overheating furnace. As a result, the unit itself won’t function properly, and those living in the home will likely see their energy bills rise. Not only that, but up to 30% of the HVAC unit’s overall output can be compromised when not properly insulated.

When it Comes to the Furnace, Size is Everything

By “size is also everything”, we don’t mean they need to be as big as you can possibly get them. Rather, the important thing to consider after finishing your HVAC training is to find a furnace that is sized proportionately to the one previously in place, and is also a newer model.

This not only helps with the flow of air in the home, but with the system’s efficiency as a whole. Should you not pick a correctly sized furnace, problems could occur. This includes the unit overworking itself to provide better cooling or heat if too small, or uneven temperatures if too big. However, be sure to double-check that the size calculations are correct, even if it’s technically the same size as the previous furnace.

Make Sure Air is Properly Distributed at All Times

This is one of the most crucial parts of a successful HVAC installation, as it can otherwise lead to uneven cooling or heating. HVAC school students should be aware that proper air distribution design is a must, and that the ductwork is symmetrical in size to the unit’s output capacity.

To achieve this, apply new ductwork rather than the preexisting one, and be sure it’s distributing air evenly. Another of the more important aspects to keep in mind is proper ventilation. You’ll need to ensure the HVAC unit you’ve installed has a strong balance of both hot and cold air, and that the air is balanced and flows cleanly throughout the home.

Heating, ventilation, and air conditioning (HVAC) technicians specialize in keeping houses and the people that live in them warm in the winter and cool in the summer. Read these tips and tricks to make your customer’s home a firelit haven, sheltered from the icy elements outdoors.

Seal Any Gaps When You Become an HVAC Technician

One of the main causes of a cold house is gaps around the doors and windows that let hot air out and cool air in. When you become an HVAC technician, the first thing you should do when you get a new client is examine their home for any unsealed gaps.

They can use an acrylic-latex caulk to seal any gaps around the window frames or a spray foam that will expand into any unfilled crevices. This will also help clients to save on their energy bills, as they will need less energy to heat their homes.

If the house has a fireplace, the chimney pipe could be letting cold air in,too. When the fire is not lit,advise clients that they should close the damper. However, make sure they know to check that all embers have fully burnt out – otherwise, smoke could fill their home.

Reverse Any Fans

You might assume that fans are only useful in the hot, summer months when you need to cool down. However, fans can also keep a house warm. If you reverse the direction of the fan so it’s spinning clockwise, it will stop the hot air from rising, and push it back down to warm the room. This can be a very useful tip for many clients.

Look After The Furnace and Outdoor Unit

The majority of HVAC systems have an outdoor unit attached to the outside of the house. Even though this is built to withstand cold temperatures and heavy snow, it is still a good idea to shelter it in someway. You could build a small, temporary shelter out of wood, or use a plastic cover. This will protect the fan from freezing so that your house stays warm all winter.

At HVAC college, you may also learn the importance of checking the furnace filter. This can become dirty over time and needs to be regularly cleaned and replaced. A dirty furnace filter will not be as effective, and will mean that the house needs to use more power to generate heat.

Thermostat or Portable Heater? It Depends

Both thermostats and portable heaters have an important role to play during winter. To save energy, it’s recommended that clients program the thermostat so that it automatically turns down when they are asleep or at work. The recommended temperatures are 20 degrees Celsius in the mornings, evenings, and weekends when at home, and 10 degrees Celsius when at work, asleep, or out of the house.

If a client needs to heat up their house fast,you should advise them that turning the thermostat to max is not the answer. This will drain energy and could damage the thermostat. It also won’t be effective, because the thermostat is designed to maintain a constant temperature.

In these situations, it’s better to use a portable heater. These can generate a lot of heat from electricity in a short amount of time. However, clients need to be sure to switch them off when they are not in the room, so as not to create a health and safety risk.

Since heat pumps are such a common tool in the heating, ventilation, and air conditioning (HVAC) industry, aspiring technicians should expect to become very familiar with them throughout their education and future career. Read on for an introduction to heat pumps to get you warmed up!

Learn How Heat Pumps Work With an HVAC Diploma

Heat pumps are not a new technology. In fact, the first heat pump was invented in 1948 by Robert C. Webber. Since then, the technology has been developed to resemble the air conditioning and heating units we have in our homes and offices today. HVAC technician courses will give you the opportunity to learn hands-on how this technology works.

Heat pumps can provide both heating and cooling services. In heating mode, heat is absorbed from outside by the condenser coil and transferred to the interior space via air vents. Even on cold winter days, heat pumps are able to collect warm air from outside. However, if there’s not enough warm air outside, heat pumps can use electric energy or an additional gas furnace to provide extra heat.

In air conditioning mode, the cycle is reversed. Warm air inside the house is pulled into the system with a motorized fan and transferred outside, usually behind or underneath the condenser coil. Cool and dehumidified air then enters the home through the air vents.

Heat Pumps are Energy Efficient

Eco-conscious homeowners will be relieved to discover that heat pumps are incredibly energy efficient. As you will learn in HVAC technician training, heat pumps generate 4 units of thermal energy per 1 unit of electricity used – that’s an efficiency rating of 400%!

In contrast, electrical heaters are 100% efficient, meaning that they generate 1 unit of thermal energy for every 1 unit of electricity. As well as this, heat pumps generate zero emissions, so are a great option for people that want to warm or cool their homes without damaging the planet.

Air Source vs. Ground Source Heat Pumps

As an HVAC technician, you will need to know about two main types of heat pumps: air source and ground source. Air source heat pumps are the most common type and absorb or reject heat from the outdoor air.

As the name suggests, ground source heat pumps get heat from the ground or from water. These are sometimes referred to as geothermal heat pumps and are actually slightly more efficient than air source systems. However, they are more expensive and complicated to install as the systems will need to be built into the soil around a home.

What are the Main Heat Pump Parts?

Air source and ground source heat pumps are made up of a number of components. These include:

• Compressor– to move the refrigerant through the system
• Control board – to control whether the system is in cooling or heating mode
• Condenser coil – to transfer heat outside in cooling mode
• Evaporator coil–to transfer heat inside in heating mode
• Refrigerant – a chemical substance that moves heat through the system
• Thermostat – to choose the desired temperature
