How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots throughout your Reinholds home, you’re not alone. This is a fairly regular issue. While it can seem like a major issue, the good news is that the typical causes of hot and cold spots are normally easy to fix with a normal 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 inefficiently 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 customize 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 designated 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 heat chamber sunroom comfortable all summer. Plus, when you use it 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 is not sized appropriately for the room that needs heated and cooled, or it’s designed the wrong way. We find this is especially commonplace in homes that were built before many of today’s tools and training were available. 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 needed and decrease its life. The pros at County Line Mechanical LLC 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 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 become leaky over time. Experts like County Line Mechanical LLC can inspect your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a pretty routine 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 throughout your home. Improperly sized HVAC equipment may 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 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 well.
