How to Find and Fix Hot and Cold Spots

Service

If you realize that you have hot and cold spots through your Lincoln home, you’re not alone. This is a fairly common problem. While it may seem like a big issue, 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
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you can customize the air temperature in each zone. The system is composed of multiple thermostats that operate dampers in 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 meet the thermostat's settings. This might be the key to keeping that one frozen 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 isn’t sized correctly for the space 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 available. Unfortunately, even the most energy-efficient HVAC equipment can’t match 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 more frequently than it should and reduce its lifespan. The professionals at AW Heating & Air Conditioning can help you figure out 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 could still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Professionals like AW Heating & Air Conditioning can check your ducts and let you know if they need sealed. They could also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a generally easy 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 throughout your home. Improperly sized HVAC equipment may be the culprit. 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 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 well.
