How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots through your McMurray home, you’re not alone. This is a pretty regular occurrence. While it may seem like a major concern, the good news is that the common 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 inadequately 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 means you can determine the air temperature in each zone. The system uses multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their designated zone, then open or close the dampers according to the thermostat's settings. This might be the missing piece to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning could 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 area that needs heated and cooled, or it’s improperly designed. We find this is fairly 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 poor duct system could actually cause new equipment to work more frequently than necessary and shorten its life cycle. The professionals at Kowalski Heating & Cooling 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 commonplace for the ducts in a home to become leaky over time. Pros like Kowalski Heating & Cooling can check 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 generally 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 feeling hot and cold spots throughout your home. Improperly sized HVAC equipment may be the culprit. A system that is too small has to run harder to heat or cool your home, which leaves hot and cold spots because it can’t handle 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 correctly.
