How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots through your Saint Charles home, you’re not alone. This is a relatively regular occurrence. While it can seem like a larger problem, the good news is that the typical causes of hot and cold spots are typically easy to fix with a simple 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
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and means you can customize the air temperature in each zone. The system is composed of multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated 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 hot box sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can 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 is the wrong size for the space that needs heated and cooled, or it’s poorly designed. We find this is fairly common in homes that were built before many of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t meet homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more often than it should and shorten its lifespan. The professionals at Air Alliance Team 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 properly designed and sized for your home, it could still be the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak some over time. Professionals like Air Alliance Team can check your ducts and let you know if they ought to be sealed. They might also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a fairly easy fix.

Improperly Sized HVAC Equipment
So there’s a chance 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 could be the cause. A system that is too small has to run harder to heat or cool your home, which leaves hot and cold spots because it can’t take care of 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 properly.
