How to Find and Fix Hot and Cold Spots

July 06, 2017

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

  • Lack of 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 splits your home into separate areas, known as “zones,” and allows you to customize the air temperature in each zone. The system uses multiple thermostats that operate 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 according to the thermostat's settings. This may be the missing link to keeping that one freezing bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you use it 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 poorly designed. We find this is fairly normal in homes that were built before many of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to 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 needed and decrease its life. The pros at Tokay Heating and Air Conditioning 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 common for the ducts in a home to become leaky over time. Professionals like Tokay Heating and Air Conditioning can inspect your ducts and let you know if they ought to be sealed. They might also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a pretty simple 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 might be the issue. 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 correctly.
