How to Find and Fix Hot and Cold Spots

Service

If you discover that you have hot and cold spots through your Shreveport home, you’re not alone. This is a pretty normal issue. While it might seem like a larger concern, the good news is that the typical causes of hot and cold spots are usually easy to fix with a simple air conditioning service. The most common causes for hot and cold spots are:

  • Lack of 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 divides your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system involves multiple thermostats that run dampers in 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 may be the missing link to keeping that one cold bedroom warm in the winter, or that smoldering 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 space that needs heated and cooled, or it’s improperly designed. We find this is fairly commonplace in homes that were built before a lot 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 Moon's Air can help you figure out 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 may 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. Pros like Moon's Air can inspect your ducts and let you know if they should be sealed. They could also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a pretty easy 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 feeling hot and cold spots through your home. Improperly sized HVAC equipment may be the issue. 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 handle 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 correctly.
