How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Denver home, you’re not alone. This is a relatively normal problem. While it may seem like a big problem, 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 common causes for hot and cold spots are:

  • Lack of 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 means you can set the air temperature in each zone. The system is composed of multiple thermostats that run 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 according to the thermostat's settings. This could be the key 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 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 not sized appropriately for the area that needs heated and cooled, or it’s improperly designed. We find this is pretty commonplace 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 bad duct system could actually cause new equipment to work more frequently than needed and reduce its life cycle. The professionals at Northglenn Heating & Air Conditioning, 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 properly designed and sized for your home, it could still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to leak some over time. Experts like Northglenn Heating & Air Conditioning, Inc. can inspect your ducts and let you know if they should be sealed. They might also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally simple 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 feeling hot and cold spots through 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 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 correctly.
