How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Bakersfield home, you’re not alone. This is a pretty 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 common causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately insulated air ducts
  • HVAC equipment that is too big or too small

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 customize the air temperature in each zone. The system involves multiple thermostats that control 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 to meet the thermostat's settings. This might be the key to keeping that one freezing 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 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 improperly designed. We find this is pretty 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 meet 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 often than it should and decrease its life. The experts at Hillcrest Air Conditioning & Plumbing 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 designed and sized appropriately for your home, it may still be the cause of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Pros like Hillcrest Air Conditioning & Plumbing 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 properly 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 around your home. Improperly sized HVAC equipment could be the cause. A system that is too small has to work 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 mean problems because it’ll cycle on and off too often to do its job properly.
