How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots in your Gresham home, you’re not alone. This is a fairly common problem. While it might seem like a larger issue, the good news is that the common 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:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or poorly insulated air ducts
  • Improperly sized HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system divides your home into separate areas, known as “zones,” and means you’re able to customize the air temperature in each zone. The system is composed of multiple thermostats that operate 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 might be the key to keeping that one freezing bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used 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 isn’t sized correctly for the space that needs heated and cooled, or it’s designed the wrong way. We find this is pretty common in homes that were built before a lot of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a shoddy duct system could actually cause new equipment to work harder than necessary and shorten its life. The professionals at Honke Heating & AC 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 properly 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. Pros like Honke Heating & AC can inspect 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 adequately insulated. Fortunately, this is also a generally 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 experiencing hot and cold spots through 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, leaving you with hot and cold spots because it can’t take care of 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.

No matter what’s the culprit of the hot and cold spots in your home, Honke Heating & AC can help. Just give us a call at 503-663-8033 and we’ll help you figure it out and determine if you need air conditioning service, or any other types of HVAC service that can help you keep your home cozy.
