How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Midlothian home, you’re not alone. This is a fairly regular issue. While it may seem like a major issue, the good news is that the typical 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 inefficiently insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system breaks up 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 control dampers in the ductwork of your forced-air system. The thermostats are always reading the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This might be the key to keeping that one frozen 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 have hot and cold spots simply because their home’s duct system is not sized appropriately for the area that needs heated and cooled, or it’s improperly designed. We find this is especially commonplace in homes that were built before much 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 allowing it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more often than needed and reduce its life cycle. The professionals at Daniel's Heating & Refrigeration Corp. 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 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. Experts like Daniel's Heating & Refrigeration Corp. can check your ducts and let you know if they should be sealed. They might 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 experiencing hot and cold spots through your home. Improperly sized HVAC equipment could be the culprit. A system that is too small has to work harder to heat or cool your home, which leaves 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 cause problems because it’ll cycle on and off too often to do its job well.
