How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Carson City home, you’re not alone. This is a relatively regular problem. While it might seem like a major problem, the good news is that the common causes of hot and cold spots are usually easy to fix with a straightforward 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 inadequately 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 uses multiple thermostats that run dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This might be the key 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 is the wrong size for the area that needs heated and cooled, or it’s poorly designed. We find this is fairly 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 meet homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a bad duct system could actually cause new equipment to work more frequently than necessary and reduce its lifespan. The professionals at Anderson Heating & A/C 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 might still be at the root of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Professionals like Anderson Heating & A/C 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 correctly insulated. Fortunately, this is also a pretty simple 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 through your home. Improperly sized HVAC equipment might be the issue. 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 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.
