How to Find and Fix Hot and Cold Spots

July 06, 2017

If you discover that you have hot and cold spots throughout your Pella home, you’re not alone. This is a fairly regular issue. While it can seem like a big issue, the good news is that the normal causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most common causes for hot and cold spots are:

  • Zero 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’re able to set the air temperature in each zone. The system is composed of multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated zone, then open or close the dampers to match up with the thermostat's settings. This might be the missing piece to keeping that one freezing bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning may 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 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 used. Unfortunately, even the most energy-efficient HVAC equipment can’t meet homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more frequently than it should and reduce its lifespan. The experts at Van Haaften Plumbing & Heating 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 might still be at the root of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak some over time. Pros like Van Haaften Plumbing & Heating can look at your ducts and let you know if they need sealed. They may also find that your ducts aren’t leaking, but they’re not properly 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 throughout your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to operate harder to heat or cool your home, meaning you have 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 properly.
