How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Buellton home, you’re not alone. This is a relatively common issue. While it might seem like a larger concern, the good news is that the common causes of hot and cold spots are usually easy to fix with a normal 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 inadequately insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and means you’re able to set the air temperature in each zone. The system is composed of multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This might be the missing link 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 have hot and cold spots simply because their home’s duct system is the wrong size for the space that needs heated and cooled, or it’s improperly designed. We find this is pretty normal in homes that were built before many 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 allowing it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more often than it should and decrease its life cycle. The pros at Allstar Heating & Air Conditioning 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 could still be the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak some over time. Experts like Allstar Heating & Air Conditioning can check your ducts and let you know if they need sealed. They may 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 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 around your home. Improperly sized HVAC equipment could be the culprit. A system that is too small has to work harder to heat or cool your home, which leaves 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 properly.
