How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots throughout your Alliance home, you’re not alone. This is a pretty common issue. While it may seem like a major concern, the good news is that the normal causes of hot and cold spots are typically 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
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system is composed of multiple thermostats that control dampers within 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 might be the missing link to keeping that one cold 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 is not sized appropriately for the area that needs heated and cooled, or it’s poorly designed. We find this is especially common 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 permitting it to do its job. In fact, a poor duct system could actually cause new equipment to work more frequently than it should and decrease its life cycle. The pros at Jack's Heating, Cooling, Stoves & Fireplaces 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 properly designed and sized for your home, it could 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. Experts like Jack's Heating, Cooling, Stoves & Fireplaces can inspect your ducts and let you know if they ought to be 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment may be the issue. A system that is too small has to operate harder to heat or cool your home, meaning you have hot and cold spots because it can’t keep up with 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 correctly.

No matter what’s the culprit of the hot and cold spots in your home, Jack's Heating, Cooling, Stoves & Fireplaces can help. Just give us a call at 308-646-3827 and we’ll help you decide what the issue is and determine if you need air conditioning service, or any other types of HVAC service that will help you keep your home cozy.
