How to Find and Fix Hot and Cold Spots

Service

If you find that you have hot and cold spots in your Marshfield home, you’re not alone. This is a relatively normal problem. While it may seem like a big problem, the good news is that the common causes of hot and cold spots are typically easy to fix with a simple air conditioning service. The most common 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 splits your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system uses multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their assigned zone, then open or close the dampers to match up with the thermostat's settings. This might be the missing link to keeping that one cold bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you utilize 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 the wrong size for the area that needs heated and cooled, or it’s designed the wrong way. We find this is pretty common in homes that were built before much 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 permitting it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more often than necessary and reduce its life. The pros at House of Heating Incorporated 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 may 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 House of Heating Incorporated can look at your ducts and let you know if they should be sealed. They might also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally simple 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 noticing hot and cold spots throughout your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to run 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 mean problems because it’ll cycle on and off too often to do its job correctly.
