How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots in your Columbus home, you’re not alone. This is a pretty normal problem. While it might seem like a big concern, the good news is that the typical causes of hot and cold spots are typically easy to fix with a normal 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 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 means you can set the air temperature in each zone. The system uses multiple thermostats that operate dampers in the ductwork of your forced-air system. The thermostats are always reading the temperature of their assigned zone, then open or close the dampers according to the thermostat's settings. This may be the missing link to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning could 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 is not sized appropriately for the room that needs heated and cooled, or it’s designed the wrong way. We find this is especially commonplace 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 match homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a shoddy duct system could actually cause new equipment to work harder than necessary and shorten its life. The professionals at Wolfe & Sons Heating and Cooling 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 might still be the source of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak some over time. Pros like Wolfe & Sons Heating and Cooling can look at your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a fairly simple fix.

Improperly Sized HVAC Equipment
So there’s a chance your air duct system is just fine and you have a good zoning system, but you’re still feeling hot and cold spots throughout your home. Improperly sized HVAC equipment could be the cause. 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 take care of 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 properly.
