How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots through your Scottsboro home, you’re not alone. This is a pretty regular issue. While it may seem like a major issue, 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 common causes for hot and cold spots are:

  • No zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately 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 uses multiple thermostats that control dampers inside 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 meet 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 you utilize 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 fairly commonplace in homes that were built before many of today’s tools and training were available. 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 it should and shorten its life cycle. The experts at Southern Heating & Cooling Inc. 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 properly designed and sized 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 leak some over time. Pros like Southern Heating & Cooling Inc. can look at your ducts and let you know if they should be sealed. They could also find that your ducts aren’t leaking, but they’re not adequately 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 feeling hot and cold spots throughout your home. Improperly sized HVAC equipment might 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 leave you with problems because it’ll cycle on and off too often to do its job correctly.
