How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots in your Rapid City home, you’re not alone. This is a pretty regular problem. While it might seem like a major concern, the good news is that the typical 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:

  • Lack of 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 splits your home into separate areas, known as “zones,” and means you’re able to customize the air temperature in each zone. The system involves multiple thermostats that operate dampers in the ductwork of your forced-air system. The thermostats are always reading the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This could be the missing link to keeping that one frozen bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning can 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 room that needs heated and cooled, or it’s improperly designed. We find this is especially common in homes that were built before a lot of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work harder than needed and reduce its life cycle. The professionals at Street Heating and Cooling 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 appropriately 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 become leaky over time. Pros like Street Heating and Cooling can look at your ducts and let you know if they need 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 possibly 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 work harder to heat or cool your home, which leaves 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 mean problems because it’ll cycle on and off too often to do its job well.
