How to Find and Fix Hot and Cold Spots

Service

If you realize that you have hot and cold spots through your Tampa Bay home, you’re not alone. This is a fairly common issue. While it might seem like a big concern, the good news is that the normal causes of hot and cold spots are usually easy to fix with a simple 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
  • 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 uses multiple thermostats that run dampers in 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 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 the wrong size for the room that needs heated and cooled, or it’s designed the wrong way. We find this is especially common in homes that were built before a lot of today’s tools and training were used. 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 often than needed and decrease its life cycle. The experts at Langford Cooling can help you figure out 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 might still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to leak a bit over time. Experts like Langford Cooling can check 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 adequately insulated. Fortunately, this is also a pretty simple fix.

Improperly Sized HVAC Equipment
So maybe your air duct system is just fine and you have a good zoning system, but you’re still noticing hot and cold spots throughout your home. Improperly sized HVAC equipment might be the issue. 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 take care of 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.
