Why HVAC Systems are a Complex Job That Requires an Expert Installer

HVAC systems rely on air ducts for the proper circulation of warm and cool air into rooms. A system that is installed incorrectly or is either too big or small can lead to higher energy costs, increased wear-and-tear, and early wear and tear.

Experienced HVAC technicians can perform a load calculation to ascertain an ideal unit size for a property, taking into account factors like its square footage, location, construction materials, and age.


HVAC installation is a complex task that requires the expertise of licensed professionals. The installation process includes several steps, such as sizing the system, connecting it to the ductwork, and verifying adequate power supplies.

Compliance with federal regulations regarding handling refrigerants must also be ensured. HVAC contractors may specialize in certain areas or types of equipment.

The first step of HVAC installation involves assessing the space where the system will be placed, which you can learn how to do here: https://www.energy.gov/eere/buildings/articles/residential-hvac-installation-practices-review-research-findings. This involves taking measurements of floor area and ceiling height as well as counting windows and doors before engaging an HVAC contractor to design an HVAC system specific to that location.

Once the system has been designed, installation begins. This involves installing air handlers, condensers, compressors, and pipes – as well as connecting and sealing any refrigerant lines – before connecting the ductwork and insulation for the proper functioning of the system.

Dependent upon the system being installed, it may be necessary to remove existing equipment – an often messy process in occupied buildings. Some systems require altering structures by adding ducts or changing room layouts.

Some older buildings feature outdated heating and cooling systems that cause discomfort as well as higher energy bills.

If this is the case for you, your HVAC technician should consult with building management to assess if there is enough electrical capacity for an upgrade; ensure any new equipment does not interfere with historical details or cause structural issues when making any upgrades.


HVAC commissioning is an integral step of the installation process, helping to ensure that systems are working as intended while also providing building owners with documentation of equipment performance.

Commissioning also serves to meet energy efficiency and comfort goals within buildings.

Commissioning begins during the pre-design stage of a project when owners set performance goals and IEQ standards.

Engineers then design HVAC systems based on those specifications; commissioning professionals then verify whether their designs meet them.

Once construction begins, contractors install equipment according to specifications; pre-functional checklists are conducted by commissioning professionals to make sure it’s ready for full operation.


HVAC systems can last much longer when properly maintained. A professional should perform regular checks to make sure all parts are functioning as they should and look for any problems which need fixing before becoming an emergency situation. This involves inspecting fans, air filters, evaporator coils, and any other parts in detail.

If your evaporator coil is covered with mold, dust, or debris, it should be thoroughly cleaned using a wet/dry vacuum to suction away sludge, while bleach can further disinfect it. Air filters must be periodically replaced in order to maintain indoor air quality – tight filters reduce airflow which forces your system to work harder and can compromise its operation.

HVAC professionals will ensure the thermostat is set appropriately to achieve energy efficiency goals and find a programmable thermostat that allows owners to set different temperatures at various times of day; this allows units to run less often and use less electricity.

Condensate drain lines must also be checked regularly to make sure they remain free from algae or debris, otherwise, this could lead to water leaking through ceiling leaks. A wet/dry vacuum or even just a bucket of water may help clear away sludge build-up to keep things flowing smoothly.


If your HVAC system is nearing the end of its lifespan or you’ve noticed sudden energy bills without seasonal adjustments, now may be an opportune time to replace it.

Your local HVAC installer in Columbus, OH, or dealer can assist in selecting an ideal system size for your home based on factors like size, layout, ductwork configuration, and energy savings goals. This way, they can ensure you end up with maximum comfort and savings from it!

As part of the replacement process, one important aspect is assessing your home’s heating and cooling loads to help your dealer select an ideal HVAC unit size.

Calculating load involves taking into account factors like square footage, location, building materials and age to calculate how much energy will be necessary to make you comfortable – too much energy can increase utility costs while too little will not treat indoor air properly enough for effective treatment.

Once you have decided on a new HVAC system, your technician will assess its existing installation to see what repairs or modifications need to be made prior to beginning installation of it.

Any major ductwork repairs could significantly delay this project; in addition, they will assess whether your old outside unit can be removed in favor of installing the new one in its place.
