How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Olathe home, you’re not alone. This is a fairly common issue. While it can seem like a big issue, the good news is that the typical causes of hot and cold spots are typically 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
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system uses multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated zone, then open or close the dampers according to the thermostat's settings. This may be the key to keeping that one frozen bedroom warm in the winter, or that hot box 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 have hot and cold spots simply because their home’s duct system is the wrong size for the space that needs heated and cooled, or it’s designed the wrong way. We find this is pretty commonplace in homes that were built before a lot of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t match 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 often than necessary and reduce its lifespan. The professionals at Polestar Plumbing, Heating & Air Conditioning 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 properly for your home, it could still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to leak some over time. Pros like Polestar Plumbing, Heating & Air Conditioning can look at your ducts and let you know if they should be sealed. They could 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to operate 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 mean problems because it’ll cycle on and off too often to do its job properly.
