How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your West Valley home, you’re not alone. This is a pretty regular issue. While it might seem like a larger issue, the good news is that the normal causes of hot and cold spots are normally easy to fix with a straightforward 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 poorly insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you’re able to set the air temperature in each zone. The system involves 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 to match up with the thermostat's settings. This could be the key to keeping that one cold bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning may mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners have hot and cold spots simply because their home’s duct system isn’t sized correctly 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 many of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a poor duct system could actually cause new equipment to work more frequently than needed and decrease its lifespan. The pros at Select Comfort System Heating & Air Conditioning can help you figure out 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 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. Professionals like Select Comfort System Heating & Air Conditioning 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 generally routine 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 throughout 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 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 properly.
