If you discover that you have hot and cold spots in your Alice home, you’re not alone. This is a relatively regular occurrence. While it might seem like a big issue, the good news is that the common causes of hot and cold spots are usually easy to fix with a straightforward air conditioning service. The most common causes for hot and cold spots are:
- Zero 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 divides your home into separate areas, known as “zones,” and means you can determine the air temperature in each zone. The system uses multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their assigned zone, then open or close the dampers to match up with the thermostat's settings. This might be the missing link 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 could mean home energy savings of up to 35 percent.*
Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s poorly designed. We find this is especially common in homes that were built before much of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a bad duct system could actually cause new equipment to work harder than necessary and reduce its life. The pros at Rescue Heating & Air 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 might still be the source of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Experts like Rescue Heating & Air 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 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 feeling hot and cold spots around your home. Improperly sized HVAC equipment might be the culprit. A system that is too small has to run harder to heat or cool your home, meaning you have hot and cold spots because it can’t handle 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 properly.
