How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots in your Wisconsin Rapids home, you’re not alone. This is a pretty common issue. While it can seem like a big concern, the good news is that the normal causes of hot and cold spots are usually easy to fix with a straightforward 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 poorly insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you’re able to set the air temperature in each zone. The system involves multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This might be the missing link to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you utilize it 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 poorly designed. We find this is pretty common in homes that were built before much 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 poor duct system could actually cause new equipment to work more frequently than it should and shorten its life cycle. The professionals at Rapids Sheet Metal Works Inc 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 appropriately for your home, it may still be at the root of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Professionals like Rapids Sheet Metal Works Inc can inspect your ducts and let you know if they ought to be sealed. They could also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a fairly 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 through your home. Improperly sized HVAC equipment might be the issue. 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 take care of 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.
