How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Plainfield home, you’re not alone. This is a relatively normal problem. While it might seem like a big problem, the good news is that the common causes of hot and cold spots are typically easy to fix with a simple air conditioning service. The most routine 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
  • 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 means you can customize the air temperature in each zone. The system involves multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats are always reading the temperature of their designated zone, then open or close the dampers to meet the thermostat's settings. This could be the key to keeping that one cold bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when you use 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 space that needs heated and cooled, or it’s poorly designed. We find this is fairly commonplace in homes that were built before many of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to 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 often than necessary and shorten its life. The pros at PWA 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 could still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Professionals like PWA Heating & Cooling Inc can look at 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 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 around your home. Improperly sized HVAC equipment could be the cause. 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 take care of 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.
