How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots through your Marshalltown home, you’re not alone. This is a fairly normal problem. 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 simple air conditioning service. The most likely causes for hot and cold spots are:

  • No 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 splits your home into separate areas, known as “zones,” and allows you 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 are always reading the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This could be the key to keeping that one freezing 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 area that needs heated and cooled, or it’s improperly designed. We find this is pretty commonplace in homes that were built before much of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t allowing it to 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 designed and sized properly for your home, it could still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Experts like Kapaun & Brown Inc. can inspect your ducts and let you know if they ought to be sealed. They may also find that your ducts aren’t leaking, but they’re not adequately 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 issue. 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 handle 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.
