How to Find and Fix Hot and Cold Spots

If you realize that you have hot and cold spots through your Vancouver home, you’re not alone. This is a relatively regular problem. While it might seem like a larger issue, the good news is that the common 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
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you’re able to determine the air temperature in each zone. The system involves multiple thermostats that run dampers in 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 may be the key to keeping that one frozen bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning can 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 poorly designed. We find this is especially normal 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 match homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a poor duct system could actually cause new equipment to work harder than necessary and reduce its life cycle. The professionals at Air Pro Heating & Cooling LLC 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 properly designed and sized for your home, it could still be the cause of your home’s hot and cold spots. It’s normal for the ducts in a home to become leaky over time. Pros like Air Pro Heating & Cooling LLC 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 adequately insulated. Fortunately, this is also a generally routine 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 through your home. Improperly sized HVAC equipment may be the cause. A system that is too small has to run 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 leave you with problems because it’ll cycle on and off too often to do its job properly.
