How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots in your Anaheim home, you’re not alone. This is a relatively normal problem. While it might seem like a larger issue, 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:

  • 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 splits your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system is composed of multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their assigned zone, then open or close the dampers according to the thermostat's settings. This could be the missing link 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 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 the wrong size for the room that needs heated and cooled, or it’s designed the wrong way. We find this is fairly commonplace 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 shoddy duct system could actually cause new equipment to work more often than necessary and reduce its life cycle. The professionals at Eco Fresh HVAC Inc. 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 designed and sized properly for your home, it might still be at the root of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Professionals like Eco Fresh HVAC Inc. can check your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally simple fix.

Improperly Sized HVAC Equipment
So possibly 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 might be the cause. A system that is too small has to run 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 mean problems because it’ll cycle on and off too often to do its job well.
