If you realize that you have hot and cold spots in your Excelsior Springs home, you’re not alone. This is a relatively regular problem. While it might seem like a larger concern, the good news is that the normal causes of hot and cold spots are normally easy to fix with a straightforward air conditioning service. The most common 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
- The wrong size of HVAC equipment
Lack of Zoning or Improper Zoning
A zoning system splits 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 always reading the temperature of their designated zone, then open or close the dampers according to the thermostat's settings. This could be the key to keeping that one freezing bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can 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 designed the wrong way. We find this is fairly commonplace 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 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 harder than necessary and reduce its life. The experts at Colvin's Heating and Cooling 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 appropriately 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 some over time. Pros like Colvin's Heating and Cooling 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 generally simple 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 throughout your home. Improperly sized HVAC equipment might be the cause. 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 cause problems because it’ll cycle on and off too often to do its job well.
