How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots throughout your Plover home, you’re not alone. This is a fairly regular issue. While it may seem like a larger issue, the good news is that the typical causes of hot and cold spots are normally easy to fix with a simple air conditioning service. The most routine causes for hot and cold spots are:

  • No zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately 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 allows you to customize the air temperature in each zone. The system is composed of multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This may be the key to keeping that one cold bedroom warm in the winter, or that heat chamber 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 experience 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 designed the wrong way. We find this is especially common 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 allowing it to do its job. In fact, a poor duct system could actually cause new equipment to work harder than needed and reduce its life. The pros at Point Heating & Cooling 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 might 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. Professionals like Point Heating & Cooling can inspect your ducts and let you know if they need sealed. They might also find that your ducts aren’t leaking, but they’re not correctly 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 noticing hot and cold spots throughout your home. Improperly sized HVAC equipment may be the issue. A system that is too small has to work 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 leave you with problems because it’ll cycle on and off too often to do its job well.
