How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots throughout your Kearney home, you’re not alone. This is a relatively regular occurrence. While it can seem like a larger problem, the good news is that the common causes of hot and cold spots are typically easy to fix with a simple air conditioning service. The most likely causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or poorly insulated air ducts
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you can customize the air temperature in each zone. The system uses multiple thermostats that run dampers within the ductwork of your forced-air system. The thermostats are always reading the temperature of their designated 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 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 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 around. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more often than necessary and reduce its life. The pros at Thurston Heating & Air Conditioning 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 may still be the source of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Experts like Thurston 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 fairly routine 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to work 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
