How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots in your Thedford home, you’re not alone. This is a pretty normal occurrence. While it might seem like a major issue, the good news is that the common causes of hot and cold spots are usually easy to fix with a simple air conditioning service. The most routine causes for hot and cold spots are:

  • No 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 splits your home into separate areas, known as “zones,” and means you can determine 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 designated zone, then open or close the dampers according to the thermostat's settings. This could be the missing piece to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use 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 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 poorly designed. We find this is especially 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 live up to 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 decrease its lifespan. The experts at Taylor's Heating & Air Conditioning can help you determine 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 might still be at the root of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Experts like Taylor's Heating & Air Conditioning can look at your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a generally routine fix.

Improperly Sized HVAC Equipment
So maybe your air duct system is just fine and you have a good zoning system, but you’re still feeling hot and cold spots around your home. Improperly sized HVAC equipment may be the cause. A system that is too small has to operate harder to heat or cool your home, leaving you with 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 cause problems because it’ll cycle on and off too often to do its job well.
