How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots throughout your Lawrence home, you’re not alone. This is a fairly regular issue. While it may seem like a major concern, the good news is that the typical causes of hot and cold spots are typically 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
  • Improperly sized 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 operate dampers in 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 could be the missing piece to keeping that one cold bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning could mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners have 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 poorly designed. We find this is especially common in homes that were built before much of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to 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 harder than needed and reduce its life. The professionals at Scott Temperature 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 properly for your home, it could 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. Experts like Scott Temperature can inspect your ducts and let you know if they ought to be sealed. They could also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a fairly 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 feeling hot and cold spots throughout your home. Improperly sized HVAC equipment may be the issue. A system that is too small has to run harder to heat or cool your home, leaving you with 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
