How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots throughout your Cedar Rapids home, you’re not alone. This is a pretty common issue. While it might seem like a larger 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 common causes for hot and cold spots are:

  • No 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 allows you to set the air temperature in each zone. The system uses multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing piece to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used 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 especially 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 live up to homeowners’ expectations if the duct system isn’t allowing 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 life. The professionals at Ilten's Incorporated 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 may 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. Pros like Ilten's Incorporated can inspect your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not properly 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 around 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, leaving you with 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
