How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Portland Metro home, you’re not alone. This is a relatively normal problem. While it may seem like a major problem, the good news is that the normal causes of hot and cold spots are usually 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 inefficiently insulated air ducts
  • HVAC equipment that is too big or too small

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 uses multiple thermostats that run dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This may be the missing piece to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when you utilize 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 have 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 many 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 allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than necessary and shorten its life. The experts at Central Air 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 designed and sized appropriately for your home, it might still be at the root of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Experts like Central Air Inc can look at your ducts and let you know if they need 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 there’s a chance 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 may be the culprit. A system that is too small has to work 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 cause problems because it’ll cycle on and off too often to do its job correctly.
