How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots in your Rocky Mount home, you’re not alone. This is a fairly common problem. While it may seem like a big concern, the good news is that the typical causes of hot and cold spots are normally 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 poorly insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and allows you to set the air temperature in each zone. The system uses multiple thermostats that control dampers in the ductwork of your forced-air system. The thermostats are always reading the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This might be the missing link to keeping that one cold 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 room that needs heated and cooled, or it’s designed the wrong way. We find this is fairly common in homes that were built before many of today’s tools and training were available. 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 shoddy duct system could actually cause new equipment to work more often than needed and decrease its life cycle. The professionals at Davis Heating & Air Conditioning 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 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 Davis Heating & Air Conditioning can look at 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 correctly insulated. Fortunately, this is also a pretty easy fix.

Improperly Sized HVAC Equipment
So possibly your air duct system is just fine and you have a good zoning system, but you’re still noticing hot and cold spots through your home. Improperly sized HVAC equipment might be the issue. 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 keep up with 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.

No matter what’s the culprit of the hot and cold spots in your home, Davis Heating & Air Conditioning can help.
