If you discover that you have hot and cold spots in your Sacramento home, you’re not alone. This is a pretty regular issue. While it might seem like a major concern, the good news is that the typical causes of hot and cold spots are normally easy to fix with a simple 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 poorly insulated air ducts
- HVAC equipment that is too big or too small
Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you’re able to set 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 designated zone, then open or close the dampers to meet 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 may 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 the wrong size for the room that needs heated and cooled, or it’s designed the wrong way. We find this is especially commonplace in homes that were built before much of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t match 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 decrease its lifespan. The experts at American HVAC Inc 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 at the root 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 American HVAC Inc can inspect your ducts and let you know if they ought to be sealed. They could also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a generally routine 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 noticing hot and cold spots through your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to work 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.
