How to Find and Fix Hot and Cold Spots

July 06, 2017

If you discover that you have hot and cold spots through your Brookfield home, you’re not alone. This is a fairly regular issue. While it may seem like a big concern, the good news is that the typical causes of hot and cold spots are normally easy to fix with a straightforward 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 divides your home into separate areas, known as “zones,” and means you can 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 assigned zone, then open or close the dampers to match up with the thermostat's settings. This may be the missing piece to keeping that one cold bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning can 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 improperly designed. We find this is pretty normal 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 match homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a poor duct system could actually cause new equipment to work harder than necessary and decrease its life. The professionals at Central Air LLC 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 properly designed and sized for your home, it may still be at the root of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Pros like Central Air LLC can check your ducts and let you know if they need sealed. They may also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a generally routine 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 around your home. Improperly sized HVAC equipment may 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.
