How to Find and Fix Hot and Cold Spots

Service

If you find that you have hot and cold spots through your Mount Pleasant home, you’re not alone. This is a pretty regular occurrence. While it may seem like a big concern, the good news is that the normal causes of hot and cold spots are usually easy to fix with a normal air conditioning service. The most routine causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or poorly 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 specific zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing piece to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning may 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 area that needs heated and cooled, or it’s improperly designed. We find this is fairly normal in homes that were built before a lot of today’s tools and training were available. 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 bad duct system could actually cause new equipment to work harder than it should and reduce its life. The experts at Olde Towne 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 designed and sized properly for your home, it might still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Professionals like Olde Towne Heating & Air can check 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 fairly simple 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment could be the issue. 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 keep up with the amount of space it needs to condition. Even a system that’s too big can leave you with problems because it’ll cycle on and off too often to do its job correctly.

No matter what’s the cause of the hot and cold spots in your home, Olde Towne Heating & Air can help. Just give us a call at 843-485-0967 and we’ll help you pinpoint the problem and figure out if you need air conditioning service, or any other types of HVAC service that could help you keep your home comfortable.
