How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Marshalltown home, you’re not alone. This is a fairly common problem. While it might seem like a major concern, the good news is that the common causes of hot and cold spots are normally 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
  • 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 run dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This could be the missing piece to keeping that one cold bedroom warm in the winter, or that heat chamber 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 end up with hot and cold spots simply because their home’s duct system isn’t sized correctly for the space 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 around. Unfortunately, even the most energy-efficient HVAC equipment can’t match 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 more frequently than needed and reduce its life cycle. The experts at Kapaun & Brown Inc. 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 could still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to leak a bit over time. Pros like Kapaun & Brown Inc. can check 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 properly insulated. Fortunately, this is also a pretty easy 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 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 mean problems because it’ll cycle on and off too often to do its job correctly.
