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.

Possible Reasons For Inadequate Cooling From The Central Air System

A family might move into a house without realizing there are problems with the air conditioning system. Not until they start running the central air do they notice signs the unit is not working properly. The equipment may run an unusually long time to reach the desired temperature, or some rooms may never get cool enough. These new homeowners can hire an air conditioning contractor to diagnose the problem.

System Malfunctions

Often, the issue is a malfunction within the system. The thermostat may no longer work correctly, for example. The compressor could need repairs. Duct pipes might have separated at the joints, causing cool air to leak out. If a duct pipe comes loose from its vent, lack of airflow in that room is the result.

These spots may be difficult to find without closely inspecting all of the ductwork. Some pipes may be in inconvenient places, such as a crawl space.

Inadequate Ductwork

In other cases, the problem is with the original installation or a later modification to the house. The ductwork may always have been inadequate. A home addition constructed far from the appliance may not get enough airflow with just one vent. A heating and cooling technician might extend the pipes and add more vents where they are needed.

This work improves balance throughout the system. Sometimes even one extra vent in the house makes a big difference. Installing one or two more return air registers also can have significant positive effects. Homebuilders sometimes order a minimal number to save money on subcontracting. That decision can lead to airflow problems later.

The Unit Is Too Small

Another possible issue is the central air unit being too small for the building. The previous owners might have installed it as a do-it-yourself project and ordered a small one to save money. In contrast, the size could have been appropriate originally, but a later home addition made it inadequate. 

The new property owners have some options besides central air replacement. The cheapest option would be to install a window air conditioner in a room furthest from the appliance. Another would be having an air conditioning service provider install a ductless mini-split system.

In Conclusion

After deciding on a contractor, the homeowners can schedule an appointment for an inspection. Once the reason for the problem has been diagnosed, a solution can be completed. Now the household residents enjoy better climate control and increased satisfaction with their home.
