How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots through your Perry home, you’re not alone. This is a fairly common occurrence. While it may seem like a big concern, the good news is that the normal causes of hot and cold spots are usually easy to fix with a simple air conditioning service. The most common 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 splits your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system is composed of multiple thermostats that operate dampers inside the ductwork of your forced-air system. The thermostats constantly read 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 cold bedroom warm in the winter, or that hot box sunroom comfortable all summer. Plus, when you use it with a programmable thermostat, zoning can 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 is the wrong size 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 available. Unfortunately, even the most energy-efficient HVAC equipment can’t meet homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a shoddy duct system could actually cause new equipment to work more frequently than it should and shorten its life. The professionals at Gillman Heating and Air 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 designed and sized appropriately for your home, it may still be the source of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Professionals like Gillman Heating and Air can look at 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 pretty 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 feeling hot and cold spots through your home. Improperly sized HVAC equipment might be the cause. A system that is too small has to operate harder to heat or cool your home, meaning you have hot and cold spots because it can’t keep up with 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.
