How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Winnipeg home, you’re not alone. This is a fairly regular issue. While it may seem like a larger issue, the good news is that the typical causes of hot and cold spots are normally easy to fix with a normal 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 inadequately insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you’re able to determine the air temperature in each zone. The system uses multiple thermostats that control dampers in the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their assigned 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 hot box 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 end up with hot and cold spots simply because their home’s duct system is not sized appropriately for the room that needs heated and cooled, or it’s designed the wrong way. 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 frequently than it should and shorten its life. The experts at Kirkfield 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 the cause of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Professionals like Kirkfield Heating & Air Conditioning can check your ducts and let you know if they should be sealed. They may also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty simple 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 might be the culprit. A system that is too small has to work harder to heat or cool your home, leaving you with 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 cause problems because it’ll cycle on and off too often to do its job well.
