How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots through your Katy home, you’re not alone. This is a fairly normal problem. While it can seem like a major problem, 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 routine 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
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you’re able to determine the air temperature in each zone. The system is composed of multiple thermostats that operate 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 meet the thermostat's settings. This may be the key to keeping that one frozen bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can 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 is not sized appropriately for the room that needs heated and cooled, or it’s improperly designed. We find this is especially 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 meet 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 often than it should and decrease its life cycle. The professionals at Goode Bros AC & 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 designed and sized appropriately for your home, it could still be the cause of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Experts like Goode Bros AC & Heating can check 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 correctly insulated. Fortunately, this is also a pretty 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 noticing 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 cause problems because it’ll cycle on and off too often to do its job well.
