How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots through your Hattiesburg home, you’re not alone. This is a relatively common issue. While it can seem like a larger problem, the good news is that the normal causes of hot and cold spots are normally easy to fix with a straightforward air conditioning service. The most routine causes for hot and cold spots are:

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

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and allows you to set 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 are working nonstop, reading the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing link to keeping that one freezing 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 experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s improperly designed. We find this is pretty commonplace 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 allowing it to do its job. In fact, a poor duct system could actually cause new equipment to work more frequently than it should and reduce its life. The pros at Oak Grove Heating & Air Conditioning 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 may still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Professionals like Oak Grove Heating & Air Conditioning can look at your ducts and let you know if they should be sealed. They may also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a pretty 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment may 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 leave you with problems because it’ll cycle on and off too often to do its job correctly.

No matter what’s the cause of the hot and cold spots in your home, Oak Grove Heating & Air Conditioning can help.
