Points to Consider While Installing HVAC System

September 2022

By Admin

An HVAC system is very important for maintaining the heating and cooling needs of a home. You must opt for the perfect model and brand, as it allows you to effectively overcome the summer heat or winter’s cold. Many times, individuals who buy an air conditioner do not carry out any research before doing so. This usually results in purchasing an AC that is not proper for the home or office needs.

If you are planning on installing an HVAC system, the right thing to do is to outline all the models you have come across and do a comparison among all of them to get the one that will be perfect for your office or home. Read further, to see the essential points you should consider while getting an HVAC system installation.

Consider the Cost

While planning on getting an HVAC system, it is important to consider the cost of purchasing the unit and installing it. Many individuals usually choose the cheaper option which can sometimes bring lots of issues in the long run. A less expensive HVAC system or hiring a cheap technician to carry out the installation can result in several downsides, unnecessary HVAC repair, poor performance, and a reduced lifespan.

This does not mean that the best HVAC systems are the highest-priced ones; how you know the best is by seeking professional help from several HVAC contractors. Request a quote from all of them and use it to make your comparison. When comparing the prices, your priority should be on longevity, followed by the system's efficacy, as well as its performance.

Consider the Size of Your Office or Home Building

Whether you want to install an HVAC system in your business area or at home, consider the size of the building. The comfort required will rely on the building's size. So, purchase an HVAC system that is suitable for your building as it helps in providing a more cozy feeling for visitors and occupants of the building in any season. If you install an undersized HVAC system, your energy billing will increase because the HVAC unit will undergo a lot more work to ensure everybody is kept cool.

On the other slide, installing an oversized HVAC system can also be a problem. This is because there will be uneven heating and cooling throughout the building due to consistent short cycling. Lowering the moisture or humidity in the air will be difficult due to the operational short cycle, which can be managed through HVAC service.

You can easily get the proper HVAC size for your home and business building by consulting a reliable HVAC contractor near you. The contractor will carry out a load estimation, to evaluate the size of your property and other features such as its heating and cooling requirements. If your building is very large, after the contractor has estimated your load, it will be determined if you require one or more cooling or heating systems for a smooth HVAC system operation.

Consider Different Types of HVAC Systems and Choose the Type You Need

Different Types of HVAC Systems

HVAC systems are usually available in a vast range of models and designs, and they include:

Single-Split Unit

This type of HVAC system is identified by its name because it splits into dual units: the condensing components such as the condenser fan, the condenser, and the compressor, and the air handling components that protect the evaporator fan such as the expansion devices and the evaporator.

This HVAC system is fitting and more affordable to install than a centralized unit. They are ideal for small business areas because of their comfortable small sizes. They take up only minimal space in a room, and you can also use them at restaurants, shops, and cafes.

Multi-Split Units

Like the name, this type of HVAC system consists of more than one compressor. It commonly utilizes only one massive outdoor system to operate multiple indoor units. With this style of setup, a multi-split unit can send coolness to several rooms in a building at once, which is why it is the perfect HVAC system to install in larger spaces such as retail shops, medical offices, and other large office spaces that have multiple floors and walls.

Variable Refrigerant Flow (VRF) Unit

Variable Refrigerant Flow Unit

This type of HVAC system is different from the usual traditional types. The VFR system does not use ducting for heating and cooling the room. Rather, it utilizes refrigerant lines throughout the building. This type of HVAC system can help you save up to 30 to 40 percent on your energy cost, which makes it effective for any type of large building.

You may still get confused even after knowing the different HVAC systems available in the market, this is why you should consult your HVAC contractor to assist you in choosing the best type of HVAC system that will work perfectly for your building.

Consider the Present Condition of Your Duct System

Before you install an HVAC system, find out if your building has a ducting unit that has been in perfect condition for several years. If your centralized duct is no longer in its perfect state, seek professional help from your HVAC contractor. The contractor will assess the old duct before installing a heating and cooling system.

An old duct system should be evaluated before installation because they are likely to have damaging problems such as cracks and leaks which can render the HVAC service or installation ineffective. If you are challenged with poor ducting, you will spend more money on HVAC repair. However, your contractor can give the right recommendations on the important renovations, adjustments, and repairs, before installing the HVAC system.


While Installing an HVAC system, you may believe that it is easy to have a contractor carry out the job without first doing proper research. Knowing essential points can help you in the long run, and it can also boost the longevity and functions of your newly installed HVAC system. Therefore, before opting to get a heating and cooling system running in your building, consider the size of your building, the type of your preferred HVAC system, the condition of your ducting system, and more.
