If you realize that you have hot and cold spots in your Tuscaloosa home, you’re not alone. This is a pretty common problem. While it might seem like a major problem, the good news is that the typical 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:
- Zero 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 means you’re able to determine the air temperature in each zone. The system uses multiple thermostats that operate dampers inside the ductwork of your forced-air system. The thermostats are always reading the temperature of their assigned zone, then open or close the dampers according to the thermostat's settings. This may be the missing piece to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you utilize it 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 not sized appropriately for the area that needs heated and cooled, or it’s poorly designed. We find this is pretty commonplace in homes that were built before a lot of today’s tools and training were around. 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 shoddy duct system could actually cause new equipment to work harder than it should and shorten its lifespan. The pros at KDM Service Corporation 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 might still be at the root of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Pros like KDM Service Corporation can look at your ducts and let you know if they need sealed. They may also find that your ducts aren’t leaking, but they’re not adequately 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 feeling hot and cold spots through 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, leaving you with hot and cold spots because it can’t keep up with 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.
