How to Find and Fix Hot and Cold Spots

If you discover that you have hot and cold spots throughout your Mechanicsville home, you’re not alone. This is a pretty common issue. While it can seem like a major concern, 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 likely 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
  • HVAC equipment that is too big or too small

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 uses multiple thermostats that operate dampers in the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated zone, then open or close the dampers to match up with the thermostat's settings. This could be the missing piece 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 end up with hot and cold spots simply because their home’s duct system isn’t sized correctly for the area that needs heated and cooled, or it’s designed the wrong way. We find this is fairly commonplace in homes that were built before much of today’s tools and training were used. Unfortunately, even the most energy-efficient HVAC equipment can’t meet 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 more often than needed and reduce its life. The experts at M & S Heating & Air LLC 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 the cause of your home’s hot and cold spots. It’s commonplace for the ducts in a home to become leaky over time. Experts like M & S Heating & Air LLC 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 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment might be the cause. 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 properly.
