How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots throughout your Robstown home, you’re not alone. This is a relatively regular problem. While it may seem like a big problem, the good news is that the common causes of hot and cold spots are normally easy to fix with a normal air conditioning service. The most common 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 divides your home into separate areas, known as “zones,” and allows you to set the air temperature in each zone. The system is composed of multiple thermostats that run dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific 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 smoldering 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 end up with 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 especially normal in homes that were built before much of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than it should and reduce its life cycle. The pros at McNatt Inc 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 designed and sized appropriately for your home, it may still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to leak a bit over time. Professionals like McNatt Inc can check 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 fairly 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 around your home. Improperly sized HVAC equipment might be the culprit. 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 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.

No matter what’s the culprit of the hot and cold spots in your home, McNatt Inc can help.
