How to Find and Fix Hot and Cold Spots

July 06, 2017

If you find that you have hot and cold spots in your Monroe home, you’re not alone. This is a fairly common problem. While it may seem like a major 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 routine causes for hot and cold spots are:

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

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system uses multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing link to keeping that one freezing bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when it’s used 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 not sized appropriately for the room that needs heated and cooled, or it’s designed the wrong way. We find this is pretty normal in homes that were built before a lot of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t match 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 harder than needed and reduce its life cycle. The professionals at Lanz Furnace and Fireplace can help you decide 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 Lanz Furnace and Fireplace can check 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 adequately insulated. Fortunately, this is also a fairly simple 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 throughout your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to run harder to heat or cool your home, which leaves 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.
