How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots throughout your Dresden home, you’re not alone. This is a pretty regular problem. While it might seem like a larger concern, the good news is that the typical causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most common causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or poorly insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and means you can set 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 are working nonstop, reading the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This could be the key to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning may 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 space that needs heated and cooled, or it’s improperly designed. We find this is pretty common in homes that were built before many of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t meet 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 decrease its life cycle. The pros at McFadden Heating & Cooling can help you decide 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 might still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to leak some over time. Professionals like McFadden Heating & Cooling can check your ducts and let you know if they should be sealed. They may also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a fairly 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 through your home. Improperly sized HVAC equipment may be the culprit. 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 handle the amount of space it needs to condition. Even a system that’s too big can mean problems because it’ll cycle on and off too often to do its job well.
