How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Augusta home, you’re not alone. This is a pretty regular issue. While it may seem like a big issue, the good news is that the common causes of hot and cold spots are typically 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 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 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 always reading the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This might be the missing link to keeping that one cold bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning may 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 improperly designed. We find this is especially common in homes that were built before a lot of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than needed and decrease its life cycle. The pros at McCune Heating & Cooling 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 could still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to leak some over time. Experts like McCune Heating & Cooling can look at your ducts and let you know if they should be sealed. They may 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 possibly 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 might be the cause. A system that is too small has to run 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 mean problems because it’ll cycle on and off too often to do its job properly.
