How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots through your Hudsonville home, you’re not alone. This is a fairly regular occurrence. While it might seem like a larger 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:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system is composed of multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their designated zone, then open or close the dampers to meet the thermostat's settings. This may be the key to keeping that one freezing 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 especially normal in homes that were built before many 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 permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work harder than needed and shorten its lifespan. The experts at West Michigan Heating & Air Conditioning Services can help you decide 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 common for the ducts in a home to leak a bit over time. Pros like West Michigan Heating & Air Conditioning Services can check 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 adequately insulated. Fortunately, this is also a generally simple fix.

Improperly Sized HVAC Equipment
So there’s a chance 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 could be the culprit. A system that is too small has to operate harder to heat or cool your home, leaving you with hot and cold spots because it can’t take care of 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 well.
