The Hidden Importance of Ductwork in HVAC Installations

As an HVAC expert, I have seen many homeowners overlook the importance of ductwork when considering a new HVAC installation. HVAC, which stands for heating, ventilation, and air conditioning, is a system that includes various components such as heating and air conditioning units, ducts, and a control thermostat. These components work together to heat and cool your home efficiently. However, many people are unaware that installing new ductwork is an essential part of the HVAC installation process and can significantly impact the overall cost and efficiency of the system. When it comes to installing new ductwork, homeowners should be aware that it can increase the total cost of their HVAC installation.

This is why many homeowners are now opting for modern ductless HVAC systems. In some cases, replacing an air conditioner also requires replacing the ducts. While this may not always be necessary, most contractors will recommend it to ensure maximum efficiency and air quality. Factors such as the location of the HVAC unit in a historic home or a small attic, built-in insulation in the attic, or custom-made parts can also increase the cost of installation. There are various types of HVAC systems available for homeowners to choose from when considering a new installation.

However, if the cost of repairing an existing HVAC unit is more than 30% of the total cost of replacing it, it is advisable to opt for a new system. It is also important to note that most HVAC replacements require new ductwork. Therefore, homeowners should consult with their HVAC professional to determine if their existing ducts need to be replaced. One crucial aspect of maintaining a new HVAC unit after installation is regular maintenance. This includes replacing air filters regularly, sealing any air leaks in the ducts, cleaning up debris around the unit, maintaining a 2-foot space around it, adjusting or replacing the thermostat, and cleaning the evaporator coil, evaporator trap, and drain pipe with a garden hose.

Some HVAC companies offer discounts on more expensive options such as a zone system, and local energy companies may also provide rebates for upgrading or replacing an HVAC system, especially if it is energy-efficient. For homes without existing ductwork, homeowners can choose to install a ductless air conditioning system or have ducts installed.
