How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots in your Genoa home, you’re not alone. This is a pretty common issue. While it might seem like a big concern, the good news is that the normal causes of hot and cold spots are normally 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
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system is composed of multiple thermostats that operate dampers in 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 to meet the thermostat's settings. This could be the key to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s improperly designed. We find this is especially normal 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 live up to homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than needed and shorten its life cycle. The pros at Assured Appliance and Heating & Air 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 properly designed and sized for your home, it may 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. Professionals like Assured Appliance and Heating & Air can inspect your ducts and let you know if they ought to be sealed. They might also find that your ducts aren’t leaking, but they’re not correctly 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 experiencing 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, meaning you have 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
