HVAC System Installation, Repair Service, and Maintenance


As technology progresses with each passing day, our comfort factor has doubled, making us cozy and snuggled up inside our homes. However, these technological aspects that bring us so much luxury are often beyond our knowledge realm. One such system that takes care of us on a daily basis is the HVAC system. Found in most American households, we hardly know what goes into the making, operation, and functionality of the same.

Here we shall discuss all that goes into the making, maintenance, installation, and perfect operation of your household or commercial HVAC unit.

But, before we dive deeper into this topic, let us first outline what exactly this HVAC system is.


What is HVAC?


An HVAC system is a combination of ventilation, heating, as well as an air conditioning unit in one. When put together, this system helps heat up or cools a residential space or commercial building as per requirement. One can locate an HVAC system potentially anywhere with the need for ample environmental comfort.

These systems are becoming popular by the day as opposed to stand-alone machines that provide only cooling or only heating. Your HVAC system uses fresh air filtered from outdoors to add to the air quality indoors.

Now, let us take a look at what this acronym brings together.

  • Heating:


An HVAC system’s heating aspect helps crank up the temperature inside your room/ house or commercial space. You can set the temperature as per your requirement to counteract the winter chills taking a toll over the outdoor space.

  • Ventilation:


The ventilation facet of your HVAC system helps with better replacement and exchange of air within your living space. We often close up the indoor area with no way for the fresh air to enter. The higher the number of people living inside the house, the faster the air within gets polluted by the carbon dioxide we release as we exhale.

However, the HVAC system’s ventilation aspect helps ensure that each breath you take comprises fresh air only minus the allergens, contaminants, or bacterial pollutants. It is also ideal for perfect oxygen replenishment. 

  • Air Conditioning:


Apart from heating and ventilating your space, the HVAC system is also designed to provide air conditioning or air cooling features. If it’s the peak of summers or a general increase in humidity in your area, having an HVAC system is preferable when the heat is beyond the bearable mark.


How does your HVAC system work?


These three prime functions of the HVAC system, as mentioned above, are interrelated. This is especially true when you plan on receiving acceptable quality indoor air or thermal comfort in the long run. Your air conditioning and heating system are among the highly complicated & extensive systems present within your home.

However, when this heavy machinery tends to break apart or suffer certain issues, it can be resolved with reliable service providers or HVAC repair services if paid attention to. There are 9 critical parts that make up your HVAC system, and it is important that you familiarize yourself with the same.

These parts have been explained here to help you understand if ever any defect or error arises.

  • Air Return Section:


The air return segment is the section of your HVAC that creates an initiation spot for your house’s ventilation requirements. The return valve is designed to suck in the air and move it through the filter while passing it via the prime system. Eventually, you get a burst of fresh air that is pertinent to both your health and comfort.

However, you need to ensure that your air return segment is in the receiving end of frequent cleaning to ensure there is no buildup of dust and debris within your filters. Any possible blockage can lead to non-functioning of the filters, and all you get is cold air without any filtering. 
At times, when the blockage is a major one, the air might not pass through, and there could be added issues in your HVAC system.

  • Air Filter:


The air filter added to your HVAC system keeps particles such as dust, debris, or even mold and mildew away from the air that finally reaches you. This is critical to ensure that no one in your family suffers from breathing issues or similar allergen-induced issues. 
However, with time, your filter tends to get clogged, which requires regular maintenance and cleaning sessions from reliable HVAC professionals. 

  • Exhaust Outlets:


The exhaust outlets make up for a critical part of your HVAC system, where your machine expels any unwanted air into the outside atmosphere. When seeking the right air conditioning and heating from your unit, make sure you check the vent stack or chimney flue on an annual basis or tune the same up in case there is a breakage or malfunction.

  • Ducts:


The AC ducts are hidden channels that carry the cooled or heated air from the HVAC unit. These channels come from the central unit and diversify according to the number of rooms present in your house. 
Given the fact that the flexible AC ducts are hidden, they often tend to get ignored by the homeowners. However, it is important that you put in place a reliable plan for the efficient cleaning and maintenance of your air duct system. 
This can help you get rid of any dust or debris along with any mold or mildew development that might happen after years of moisture exposure.

  • Electrical Components:


Now, this could be a critical yet tricky part of your daily HVAC monitoring routine. We often assume that the problem is in the machine, but most of the time, the problem stems from the power circuit or similar connections. 
So, make sure you check all the connections and call a technician as soon as possible. Do not do the mistake of opting for a DIY in case there is a circuit issue or problem with any electric component. This can lead to potential electrocution or damage your unit further. So, always hire reliable HVAC contractors to get the job done.

  • Outdoor Unit:


An outdoor unit is probably the biggest part of your HVAC unit that might seem too complicated for you to understand. However, it is easy to decode and monitor the way it works. Your HVAC’s outdoor unit comprises of fans that add to the airflow requirements. 
Given the fact that the outdoor units are kept outside open to the environmental factors, it is prone to collect a lot of dirt, debris, and even cause the growth of vegetation. If plants are sucked into the unit’s fan, it can lead to serious issues that might cause a partial or complete breakdown of the HVAC unit.

  • Compressor:


As a section of your HVAC’s outdoor unit, a compressor is designed to convert the refrigerant from its gaseous state to liquid while sending it to the respective coils. As the hot air passes through the compressor, it gets cooled down and helps provide chilled air to your room via the duct. 
If there is a cooling issue with your compressor, it surely points out towards compressor-related failures. So, make sure you get your compressor checked by a professional at least once every year.

  • Coils:


The coil is one important part of your HVAC’s outdoor unit. This is where the coils tend to cool the hot air as it works its way through the same with a chunk of help coming from the cooling refrigerant. With constant heating and cooling happening in the coils, it can be prone to breakage or similar failure. So, if you happen to experience low or too highly cooling, it could be a sign of coil failure. Additionally, keep checking for frost build-up in your coils to ensure there is nothing wrong with the system. 

  • Blower:


The HVAC blower tends to draw in the warm air present within your room through the unit’s main section. This warm air makes its way to the compressor to get cooled and eventually gets diverted back to the room after the cooling and filtering process is complete. 
Do keep checking your blower for mold or mildew growth as it can make its way into your body system and cause allergies or similar problems.


HVAC system: What’s included?


Given that the HVAC system stands for ventilation, heating, and air conditioning, it is confirmed that these parts are prime in your machine. In general, the heating segment of your HVAC refers to the boiler or furnace. It comes with a durable and sturdy pipe system to help transport the fluid that carries the heat through the ductwork. 
On the other hand, the ventilation system is either forced or natural. When forced, it is doubled up as a unit for air-cleaning requirements. The 3
rd element of the HVAC system, the air conditioning unit, delivers a work model that removes the heat within your home and delivers cold air.


HVAC vs. Air Conditioning: Decoding the Differences


In the AC manufacturing industry, we often use the term HVAC interchangeably with AC. Now, air conditioning is a term generally referred to as the systems designed to cool down your house. Window units & central ACs are the standard systems used in an air conditioning unit. 
Here are some subtle yet important differences between the two:
HVAC deals with both heating as well as cooling requirements of your house, whereas the air conditioning unit is just designed to cool down space. 
AC helps wick off extra humidity from the air bringing in a comfortable environment within your house. On the other hand, the HVAC system can both add as well as remove the humidity from your space as per your requirement. 
HVAC units have a sophisticated duct system as compared to the duct system of air conditioning units.
AC units are designed to save space as compared to HVAC units that can be bulkier in nature.


What is the lifespan of a normal HVAC system used for commercial or residential spaces?


Now that you understand the HVAC system’s basics, you mind be wondering how long it lasts and is it worth the investment. The answer to this is variable and depends on a range of factors.
Here we will decode each factor responsible for the determination of your HVAC system’s lifespan. 

  • Maintenance:


The most critical and often overlooked factor is the maintenance of your heating, cooling, and ventilation unit. If you plan on receiving the warmth, comfort, and luxury provided by the unit, you need to make sure maintenance is something you never overlook. 
You can surely perform a cleaning session for the unit’s outer parts. However, refrain from entering the inner areas as this can lead to manufacturer warranty being void. Unless you are a technician with knowledge of the HVAC system, it is better to refrain from opting for DIY methodologies as it can further damage the machine to the extent that might be beyond repair and hence cost you a fortune. The right way is to call in professional help and avoid risky DIY affairs.

  • Air Filter Cleaning:


One of the important factors that add to your HVAC system’s overall life is the cleaning done for the same. Ask yourself questions such as:
How many times should I change my HVAC air filter?
How often should I clean the filter?
Is my air conditioning unit making clogged sounds?
Is the cooling on the appropriate level?
Once you have analyzed the answer to these questions, you will come to a conclusion as to whether or not your HVAC filter needs a change or quick replacement. A clogged or dirty filter can put a lot of strain on the HVAC unit. Most maintenance and repair service providers tend to suggest a filter change every 90 days. However, this change is varied depending on the number of pollutants your HVAC is exposed to. 
On the other hand, if you do use a high-quality micro-particle filter, make sure you change the filter on a monthly basis.

  • Location:


One more thing that adds in or deducts your HVAC system’s life is the location it is placed at. If you happen to live in an arid or dry climate, dust might accumulate all around the coil & filter pretty quickly. Due to this heavy accumulation, you have to opt for frequent cleaning of the entire system. 
Additionally, the humidity content in your area also plays a critical role in determining your HVAC unit’s lifespan. The higher the humidity content in the atmosphere, the harder your system has to work in order to make the area comfortable inside. 
This heavy load added to your machine can dim down the years left for the system before it needs to be replaced by a new one. Also, make sure your HVAC system’s vents aren’t in a place that is blocked by the furniture. This blockage could have an adverse impact on the functionality of the machine.

  • Constant Usage:


We all have a habit of letting things run longer than necessary until you are slapped on the face with heavy energy bills. The same thing applies to your HVAC unit as well. A unit that runs constantly tends to see a higher amount of wear & tear as compared to a unit that is used only when required. Filter changes, frequent cleanings, programmable thermostats, as well as regular maintenance, ensure that your HVAC unit runs in an efficient manner. 
Check for the answer to these questions such as:
Is your outdoor unit exposed to direct sun in summers?
Is the area around your outdoor unit covered with grass?
Is your unit located close to the driveway with direct dust pouring in?
With the right answer to these questions, you can protect the outdoor HVAC unit from elements that drop down its years of functionality. Opting for these preventative measures makes sure that you do not have to work a lot in order to keep your unit well-maintained or free from extra repair needs.

  • Proper Installation:


Lastly, you have to ensure that the HVAC unit’s installation is done only by a certified and quality system professional. Additionally, you need to decide which size fits your needs in the best way. We often assume that a large unit is ideal for your house. However, this would only lead to added energy bills. 
On the other hand, a unit that is way too small for your house can add strain to the machine, and hence your HVAC system won’t last for long. You also need to make sure that your HVAC system’s ductwork is placed properly along with the venting sections.


Why is HVAC important?


A major faction of our energy bill comes from the HVAC unit. So, you must be wondering why they are so important. Let us decode why this complex yet the important system is so critical to your home machinery list.

How does an HVAC system work?


Your HVAC undergoes plenty of synchronization to help keep your room environment cozy as per your requirement. Here is how it works:

  • Thermostat:


The part that controls each and every element of your system is the thermostat. This is the segment that you will interact with the most. It can easily be set on manual control and programmed for the ideal temperature set. Whenever the surrounding temperature turns too cold or hot, the thermostat initiates the HVAC system for controlled temperature air circulation. 

  • Furnace:


The furnace helps heat up the air, and this very air is passed into your rooms through the vents in temperature as required. It makes use of a range of heat sources such as heat pumps, solar energy, electric resistance, as well as combustion.

  • Evaporator Coil:


Your evaporator coil can help cool down your house when the thermostat is switched to a low-temperature setting. This chilled air is later funneled all throughout the house. 

  • Condensing Unit:


Found outside the house, this particular unit houses what we call as the refrigerant gas. Once this refrigerant gets cooled, this liquid is pumped through the condensing unit to the machine’s evaporator coil in order to be changed into the gaseous state once again. 

  • Vents:


These particular outlets help distribute the cooled and heated air from your AC ductwork system to different parts of the house. They are generally added to the ceiling area with the help of angle slats and are designed to move the air in a downward fashion. 

  • Refrigerant Lines:


The refrigerant lines carry the refrigerant liquid to your condensing unit while it is in the gaseous form. This change of refrigerant from liquid to gas and vice-versa helps transform the temperature of your house.
