How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Hendersonville home, you’re not alone. This is a relatively normal occurrence. While it can seem like a larger issue, the good news is that the common causes of hot and cold spots are usually easy to fix with a normal air conditioning service. The most routine causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system is composed of multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned zone, then open or close the dampers according to the thermostat's settings. This may be the missing link to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning could mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners experience hot and cold spots simply because their home’s duct system isn’t sized correctly for the room that needs heated and cooled, or it’s designed the wrong way. We find this is pretty normal in homes that were built before a lot of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than needed and reduce its life cycle. The professionals at Superior Comfort Systems can help you figure out if your duct work is working for your home.

Leaky or Inadequately Insulated Air Ducts
Even if your duct system is designed and sized properly for your home, it may still be the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to become leaky over time. Professionals like Superior Comfort Systems can check your ducts and let you know if they ought to be sealed. They could also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty routine fix.

Improperly Sized HVAC Equipment
So maybe your air duct system is just fine and you have a good zoning system, but you’re still experiencing hot and cold spots throughout your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to operate harder to heat or cool your home, meaning you have hot and cold spots because it can’t keep up with the amount of space it needs to condition. Even a system that’s too big can leave you with problems because it’ll cycle on and off too often to do its job correctly.
