How to Find and Fix Hot and Cold Spots

Service

If you discover that you have hot and cold spots throughout your Northwest Arkansas home, you’re not alone. This is a relatively regular issue. While it can seem like a major issue, 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 likely causes for hot and cold spots are:

  • No zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently 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’re able to set the air temperature in each zone. The system involves multiple thermostats that operate 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 according to the thermostat's settings. This may be the missing link 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 experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s designed the wrong way. We find this is pretty common in homes that were built before much of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to 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 more frequently than necessary and shorten its lifespan. The pros at AirTech Heating and Air Conditioning, LLC 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 cause of your home’s hot and cold spots. It’s normal for the ducts in a home to leak a bit over time. Pros like AirTech Heating and Air Conditioning, LLC can check your ducts and let you know if they ought to be sealed. They might 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment may be the cause. 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.
