How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots throughout your Elmhurst home, you’re not alone. This is a pretty regular issue. While it might seem like a big concern, the good news is that the normal causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most common causes for hot and cold spots are:

  • Zero 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 is composed of multiple thermostats that run dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This could be the missing piece to keeping that one freezing bedroom warm in the winter, or that smoldering 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 is the wrong size for the space 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 permitting it to do its job. In fact, a poor duct system could actually cause new equipment to work harder than necessary and shorten its life cycle. The experts at Alan Heating Air Conditioning, 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 may still be the source of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Pros like Alan Heating Air Conditioning, Inc. 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 pretty 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 through your home. Improperly sized HVAC equipment may be the cause. A system that is too small has to run harder to heat or cool your home, which leaves 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 mean problems because it’ll cycle on and off too often to do its job properly.
