Balancing My HVAC System

A few months ago, I realized that something was wrong with my HVAC system. It seemed like no matter what I did, some rooms were hot and some rooms were simply getting too much cooled air. Instead of trying to troubleshoot my air conditioner on my own, I called out a professional HVAC repairman for help. They went through each room of my house when the system was running to measure the outgoing airflow and to check for issues. They discovered some serious balance problems, which they resolved after running a few extra lines. Check out this blog to learn more about HVAC in general.

The Possible Need For Ductwork Modification When Climate Control Is Ineffective

Heating and cooling ductwork in a home might be considered metaphorically as veins and arteries. The arteries of the system distribute climate-controlled air from the equipment through vents. The system's veins use return registers to draw air back to the equipment. This works for both the furnace and the central air conditioner. When climate control is uneven in the home, an HVAC contractor can determine the problem and make appropriate modifications.

Design Issues

The problem can occur for various reasons. The system could have been poorly designed or inadequate when the home was built. If the home's floor plan has changed because of an addition, that part of the building might not have sufficient ductwork.

Sometimes when it's time for furnace replacement, homeowners want the contractor to install the new appliance in a different location. For instance, this could happen in a home that originally had no basement but now has one under an addition constructed later. Removing the furnace from the ground floor provides more room there.

In all of these situations, adjustments may be required to achieve optimum climate control throughout the home. In other cases, though, the problem is easier to resolve.  

Checking for Leaks

The first step is an inspection by an HVAC contractor to look for leaks in the system. In some instances, less climate-controlled air reaches a room than before because a pipe has separated from the vent. Some joints in the pipes may have come loose over many years, causing air leaks in a basement or crawl space, or behind walls. This is a common problem with an older system.

Human Behavior

Sometimes the behavior of household residents is causing the problem. When contractors initially install a furnace and central air conditioner, they balance the air pressure for the correct airflow throughout the home. If homeowners close off an unused room and shut the vents in it, this can negatively affect climate control in other parts of the building. 


Even if modifications are required, making these adjustments is significantly less costly than installing pipes in a home without any ductwork. Some older homes originally depended on a centrally located oil stove or floor furnace with one large register. Modifying this type of home for a standard gas furnace is expensive.

In contrast, adding an extra duct pipe or two with attached vents will be affordable for most homeowners. Another project might be replacing some pipes with larger ones. Anyone who wants to schedule an inspection of their home's ductwork may contact an HVAC contractor at the earliest convenience. Contact an HVAC contractor for more information.
