How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots through your Chicago home, you’re not alone. This is a relatively common problem. While it may seem like a big problem, the good news is that the typical causes of hot and cold spots are usually easy to fix with a straightforward air conditioning service. The most likely 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
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you can determine the air temperature in each zone. The system is composed of multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing link to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning may 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 not sized appropriately for the room that needs heated and cooled, or it’s poorly designed. We find this is pretty commonplace in homes that were built before many 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 permitting it to do its job. In fact, a poor duct system could actually cause new equipment to work harder than it should and decrease its lifespan. The experts at iTemp Heating and Air Conditioning 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 normal for the ducts in a home to leak some over time. Professionals like iTemp Heating and Air Conditioning can inspect your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty routine 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment could be the cause. 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
