How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Jefferson City home, you’re not alone. This is a relatively common problem. While it can seem like a big problem, the good news is that the normal causes of hot and cold spots are typically easy to fix with a simple air conditioning service. The most routine causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately 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 means you’re able to determine the air temperature in each zone. The system uses multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This might be the missing piece to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning can mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners end up with hot and cold spots simply because their home’s duct system isn’t sized correctly for the space that needs heated and cooled, or it’s designed the wrong way. We find this is fairly commonplace in homes that were built before a lot of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work harder than it should and shorten its lifespan. The pros at Stieferman Heating Company Inc can help you determine if your duct work is working for your home.

Leaky or Inadequately Insulated Air Ducts
Even if your duct system is designed and sized appropriately for your home, it could still be the cause of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Experts like Stieferman Heating Company Inc can look at your ducts and let you know if they should be sealed. They might also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty simple 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment may be the cause. A system that is too small has to run harder to heat or cool your home, meaning you have hot and cold spots because it can’t handle the amount of space it needs to condition. Even a system that’s too big can cause problems because it’ll cycle on and off too often to do its job correctly.
