How to Find and Fix Hot and Cold Spots

July 06, 2017

If you discover that you have hot and cold spots in your Moline home, you’re not alone. This is a pretty common issue. While it might seem like a larger problem, the good news is that the common causes of hot and cold spots are normally easy to fix with a straightforward air conditioning service. The most common 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 splits your home into separate areas, known as “zones,” and means you’re able to customize the air temperature in each zone. The system is composed of multiple thermostats that operate dampers inside 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 missing piece to keeping that one cold bedroom warm in the winter, or that hot box 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 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 designed the wrong way. We find this is fairly normal in homes that were built before a lot of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t meet homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a poor duct system could actually cause new equipment to work more frequently than needed and shorten its life. The experts at Freed 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 might still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to leak some over time. Professionals like Freed Heating & Air Conditioning can check your ducts and let you know if they ought to be sealed. They may also find that your ducts aren’t leaking, but they’re not adequately 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 throughout your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to operate 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
