How to Find and Fix Hot and Cold Spots

Service

If you discover that you have hot and cold spots through your Heflin home, you’re not alone. This is a relatively common problem. While it can seem like a major concern, the good news is that the typical causes of hot and cold spots are usually easy to fix with a simple 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
  • 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 is composed of multiple thermostats that control dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific 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 smoldering 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 experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s poorly designed. We find this is fairly 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 meet homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a shoddy duct system could actually cause new equipment to work harder than necessary and reduce its lifespan. The professionals at Bain Heating & Air Conditioning, 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 cause of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Pros like Bain Heating & Air Conditioning, Inc can inspect 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 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 feeling hot and cold spots around your home. Improperly sized HVAC equipment might be the issue. A system that is too small has to operate harder to heat or cool your home, leaving you with hot and cold spots because it can’t handle the amount of space it needs to condition. Even a system that’s too big can cause problems because it’ll cycle on and off too often to do its job well.

No matter what’s the culprit of the hot and cold spots in your home, Bain Heating & Air Conditioning, Inc can help. Just give us a call at 256-270-1196 and we’ll help you decide what the issue is and decide if you need air conditioning service, or any other types of HVAC service that will help you keep your home cozy.
