How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Great Falls home, you’re not alone. This is a fairly common issue. While it may seem like a big concern, the good news is that the normal causes of hot and cold spots are normally easy to fix with a simple 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
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system breaks up 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 operate dampers inside the ductwork of your forced-air system. The thermostats are always reading the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing piece to keeping that one cold bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning may mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners have 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 fairly common 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 letting it do its job. In fact, a bad duct system could actually cause new equipment to work more often than necessary and reduce its life cycle. The experts at Falls Mechanical Services 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 properly designed and sized for your home, it could still be the source of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak some over time. Pros like Falls Mechanical Services LLC can inspect your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a fairly simple fix.

Improperly Sized HVAC Equipment
So maybe your air duct system is just fine and you have a good zoning system, but you’re still experiencing hot and cold spots through your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to operate harder to heat or cool your home, leaving you with hot and cold spots because it can’t take care of 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 correctly.
