How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots in your Humble home, you’re not alone. This is a relatively normal occurrence. While it may seem like a larger concern, the good news is that the common causes of hot and cold spots are normally easy to fix with a straightforward 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 divides your home into separate areas, known as “zones,” and means you can set the air temperature in each zone. The system involves 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 could be the missing piece to keeping that one freezing bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning could 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 room that needs heated and cooled, or it’s poorly 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 permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than it should and shorten its life. The professionals at Air Houston Mechanical 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 designed and sized properly for your home, it may still be the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Pros like Air Houston Mechanical LLC can look at your ducts and let you know if they should be sealed. They may also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a pretty simple fix.

Improperly Sized HVAC Equipment
So there’s a chance your air duct system is just fine and you have a good zoning system, but you’re still feeling hot and cold spots through your home. Improperly sized HVAC equipment could 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 properly.
