How to Find and Fix Hot and Cold Spots

July 06, 2017

If you discover that you have hot and cold spots throughout your Racine home, you’re not alone. This is a fairly regular occurrence. While it may seem like a big concern, the good news is that the normal causes of hot and cold spots are normally easy to fix with a normal air conditioning service. The most likely causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you can determine the air temperature in each zone. The system uses multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This may 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 experience hot and cold spots simply because their home’s duct system isn’t sized correctly 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 many 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 permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work more frequently than needed and decrease its lifespan. The pros at Keystone Heating & Air Conditioning Co., Inc 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 may still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Pros like Keystone Heating & Air Conditioning Co., Inc can look at 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 correctly insulated. Fortunately, this is also a pretty easy fix.

Improperly Sized HVAC Equipment
So possibly 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 cause. 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 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.
