How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots in your Bloomington home, you’re not alone. This is a fairly common issue. While it may seem like a larger issue, the good news is that the normal causes of hot and cold spots are typically easy to fix with a normal air conditioning service. The most likely 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
  • 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 allows you to determine the air temperature in each zone. The system involves multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats are always reading the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This might be the missing link to keeping that one freezing bedroom warm in the winter, or that heat chamber 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 poorly designed. We find this is fairly commonplace 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 meet 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 harder than needed and decrease its life cycle. The pros at All Seasons Heating & A/C Co 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 appropriately for your home, it could still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Pros like All Seasons Heating & A/C Co can check your ducts and let you know if they need sealed. They may also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a generally 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 feeling hot and cold spots throughout your home. Improperly sized HVAC equipment might be the culprit. A system that is too small has to run harder to heat or cool your home, which leaves 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 correctly.
