How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots through your Dayton home, you’re not alone. This is a relatively regular problem. While it may seem like a larger issue, the good news is that the common causes of hot and cold spots are usually easy to fix with a normal air conditioning service. The most likely causes for hot and cold spots are:

  • No 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 customize the air temperature in each zone. The system involves multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This could be the key to keeping that one cold bedroom warm in the winter, or that smoldering 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 not sized appropriately for the area that needs heated and cooled, or it’s improperly designed. We find this is especially 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 meet homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work harder than needed and shorten its life cycle. The professionals at Jent Mechanical 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 at the root of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Pros like Jent Mechanical LLC can inspect your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty 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 throughout your home. Improperly sized HVAC equipment may be the issue. A system that is too small has to work harder to heat or cool your home, which leaves 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 mean problems because it’ll cycle on and off too often to do its job well.

No matter what’s the culprit of the hot and cold spots in your home, Jent Mechanical LLC can help.
