How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Charlottesville home, you’re not alone. This is a fairly regular problem. While it may seem like a big concern, the good news is that the normal causes of hot and cold spots are normally easy to fix with a simple 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
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and allows you to set the air temperature in each zone. The system is composed of multiple thermostats that run dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their designated zone, then open or close the dampers according to the thermostat's settings. This might be the missing piece to keeping that one cold bedroom warm in the winter, or that hot box 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 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 normal 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 match 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 decrease its lifespan. The professionals at Beck Cohen 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 properly designed and sized for your home, it might 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. Professionals like Beck Cohen can inspect your ducts and let you know if they need sealed. They may also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally 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 feeling hot and cold spots through your home. Improperly sized HVAC equipment may be the cause. 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 mean problems because it’ll cycle on and off too often to do its job well.
