How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots throughout your Lexington home, you’re not alone. This is a pretty normal problem. While it can seem like a big concern, the good news is that the typical causes of hot and cold spots are typically easy to fix with a normal air conditioning service. The most likely causes for hot and cold spots are:

  • Lack of zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately 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 can determine the air temperature in each zone. The system uses multiple thermostats that run dampers in the ductwork of your forced-air system. The thermostats are always reading the temperature of their specific zone, then open or close the dampers to meet the thermostat's settings. This may be the key to keeping that one cold bedroom warm in the winter, or that smoldering 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 have 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 fairly 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 shoddy duct system could actually cause new equipment to work harder than necessary and decrease its life cycle. The professionals at James Heating & A/C, Inc 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 may still be the source of your home’s hot and cold spots. It’s normal for the ducts in a home to leak some over time. Professionals like James Heating & A/C, Inc can check your ducts and let you know if they should be sealed. They may also find that your ducts aren’t leaking, but they’re not adequately insulated. Fortunately, this is also a pretty easy fix.

Improperly Sized HVAC Equipment
So maybe 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 cause. A system that is too small has to operate harder to heat or cool your home, which leaves 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 well.

No matter what’s the cause of the hot and cold spots in your home, James Heating & A/C, Inc can help. Just give us a call at 336-853-6070 and we’ll help you pinpoint the problem and determine if you need air conditioning service, or any other types of HVAC service that can help you keep your home comfy.
