How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots in your Grand Prairie home, you’re not alone. This is a fairly regular issue. While it might seem like a major issue, the good news is that the common causes of hot and cold spots are normally 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 inefficiently insulated air ducts
  • The wrong size of 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 involves multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their designated zone, then open or close the dampers to match up with the thermostat's settings. This could 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 could mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners experience hot and cold spots simply because their home’s duct system isn’t sized correctly for the area that needs heated and cooled, or it’s improperly designed. We find this is especially normal 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 harder than needed and decrease its life cycle. The pros at Mustang Mechanical 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 the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Pros like Mustang Mechanical can look at 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 generally easy 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 work 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 leave you with problems because it’ll cycle on and off too often to do its job properly.

No matter what’s the cause of the hot and cold spots in your home, Mustang Mechanical can help.
