How to Find and Fix Hot and Cold Spots

Service

If you find that you have hot and cold spots in your Auburn home, you’re not alone. This is a relatively normal issue. While it can 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 likely causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system uses multiple thermostats that run dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This may be the key 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 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 not sized appropriately for the room that needs heated and cooled, or it’s designed the wrong way. We find this is pretty commonplace in homes that were built before a lot of today’s tools and training were used. 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 bad duct system could actually cause new equipment to work harder than it should and shorten its lifespan. The experts at Forster Heating 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 the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Professionals like Forster Heating can inspect your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a pretty 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment could be the issue. A system that is too small has to run harder to heat or cool your home, leaving you with 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 well.
