How to Find and Fix Hot and Cold Spots

July 06, 2017

If you discover that you have hot and cold spots throughout your Saint Petersburg home, you’re not alone. This is a relatively normal issue. While it might 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 inadequately 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 allows you to determine the air temperature in each zone. The system uses multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This may 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 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 is the wrong size for the area that needs heated and cooled, or it’s improperly designed. We find this is especially commonplace in homes that were built before a lot of today’s tools and training were around. 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 bad duct system could actually cause new equipment to work harder than necessary and reduce its life cycle. The experts at Hale's Air Conditioning Services Inc 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 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 become leaky over time. Experts like Hale's Air Conditioning Services Inc can look at your ducts and let you know if they need sealed. They may 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 maybe your air duct system is just fine and you have a good zoning system, but you’re still experiencing hot and cold spots around your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to operate 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 cause problems because it’ll cycle on and off too often to do its job well.
