How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots throughout your Logan home, you’re not alone. This is a relatively common issue. While it can seem like a major problem, the good news is that the normal causes of hot and cold spots are usually easy to fix with a straightforward air conditioning service. The most likely 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
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and means you can set 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 constantly read the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This may be the missing piece to keeping that one cold bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used 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 not sized appropriately for the room that needs heated and cooled, or it’s poorly 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 letting it do its job. In fact, a poor duct system could actually cause new equipment to work more frequently than needed and reduce its life cycle. The experts at Western Mechanical, Inc. 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 designed and sized appropriately for your home, it may still be at the root of your home’s hot and cold spots. It’s common for the ducts in a home to leak some over time. Professionals like Western Mechanical, Inc. 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 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 throughout your home. Improperly sized HVAC equipment might be the culprit. 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 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.
