How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Shelby Township home, you’re not alone. This is a pretty regular occurrence. While it may seem like a big concern, the good news is that the typical causes of hot and cold spots are typically easy to fix with a simple air conditioning service. The most likely 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
  • 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 can determine the air temperature in each zone. The system is composed of multiple thermostats that control dampers in 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 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 have 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 a lot 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 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 professionals at Mr. Air Repair can help you decide 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 source of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Experts like Mr. Air Repair can check your ducts and let you know if they ought to be sealed. They could also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a pretty routine 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 could 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.
