How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots through your Baltimore home, you’re not alone. This is a relatively regular issue. While it can seem like a big problem, the good news is that the common causes of hot and cold spots are usually easy to fix with a straightforward air conditioning service. The most likely 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
  • Improperly sized 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 customize the air temperature in each zone. The system involves multiple thermostats that run 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 could be the key to keeping that one frozen bedroom warm in the winter, or that hot box 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 end up with hot and cold spots simply because their home’s duct system is not sized appropriately for the room that needs heated and cooled, or it’s poorly designed. We find this is especially common 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 letting it do its job. In fact, a bad duct system could actually cause new equipment to work more frequently than necessary and reduce its life cycle. The experts at Quality Refrigeration 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 designed and sized properly for your home, it might still be the cause of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Experts like Quality Refrigeration can inspect your ducts and let you know if they ought to be sealed. They could 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 noticing hot and cold spots throughout 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, 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 cause problems because it’ll cycle on and off too often to do its job properly.
