How to Find and Fix Hot and Cold Spots

Service

If you discover that you have hot and cold spots throughout your Hattiesburg home, you’re not alone. This is a relatively regular problem. While it may seem like a major issue, the good news is that the common causes of hot and cold spots are typically easy to fix with a simple 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 inadequately insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you’re able to set the air temperature in each zone. The system involves multiple thermostats that operate dampers in the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated zone, then open or close the dampers to match up with the thermostat's settings. This may be the missing piece to keeping that one frozen bedroom warm in the winter, or that hot box 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 experience hot and cold spots simply because their home’s duct system is the wrong size for the room that needs heated and cooled, or it’s designed the wrong way. We find this is especially 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 allowing it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more frequently than it should and reduce its life cycle. The experts at Oak Grove 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 may still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to leak some over time. Professionals like Oak Grove Heating & Air Conditioning can check your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a fairly routine 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 noticing 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 keep up with the amount of space it needs to condition. Even a system that’s too big can mean problems because it’ll cycle on and off too often to do its job correctly.
