How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Murrieta home, you’re not alone. This is a fairly normal issue. While it might seem like a larger problem, the good news is that the common causes of hot and cold spots are normally easy to fix with a normal air conditioning service. The most routine causes for hot and cold spots are:

  • Zero 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 customize the air temperature in each zone. The system uses multiple thermostats that run dampers within the ductwork of your forced-air system. The thermostats are always reading 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 hot box sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can 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 isn’t sized correctly for the room that needs heated and cooled, or it’s poorly designed. We find this is fairly common in homes that were built before many 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 letting it do its job. In fact, a poor duct system could actually cause new equipment to work harder than it should and shorten its life cycle. The experts at Cool Air Solutions 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 might still be the cause 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 Cool Air Solutions can check your ducts and let you know if they should be sealed. They could also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a generally routine 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 experiencing hot and cold spots throughout your home. Improperly sized HVAC equipment might be the cause. A system that is too small has to operate harder to heat or cool your home, meaning you have 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.

No matter what’s the culprit of the hot and cold spots in your home, Cool Air Solutions can help.
