How to Find and Fix Hot and Cold Spots

Service

If you realize that you have hot and cold spots in your Saint Peters home, you’re not alone. This is a relatively common occurrence. While it might seem like a big concern, the good news is that the common causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most routine causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or poorly insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you’re able to determine the air temperature in each zone. The system involves multiple thermostats that control dampers within 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 match up with the thermostat's settings. This may be the missing piece to keeping that one freezing 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 have hot and cold spots simply because their home’s duct system isn’t sized correctly for the room that needs heated and cooled, or it’s improperly designed. We find this is fairly normal in homes that were built before much of today’s tools and training were used. 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 it should and shorten its life cycle. The professionals at C-N-O Comfort Zone 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 designed and sized properly 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 become leaky over time. Professionals like C-N-O Comfort Zone can inspect your ducts and let you know if they ought to be sealed. They might also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a pretty easy 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 experiencing hot and cold spots through your home. Improperly sized HVAC equipment might 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 keep up with 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.
