How to Find and Fix Hot and Cold Spots

Service

If you discover that you have hot and cold spots through your the Upper Rio Grande Valley home, you’re not alone. This is a pretty common problem. 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 straightforward air conditioning service. The most likely causes for hot and cold spots are:

  • No zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inadequately insulated air ducts
  • The wrong size of HVAC equipment

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and allows you to determine the air temperature in each zone. The system involves multiple thermostats that run dampers inside the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned zone, then open or close the dampers to meet the thermostat's settings. This could 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 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 the wrong size for the area that needs heated and cooled, or it’s improperly designed. We find this is especially commonplace in homes that were built before much of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t match homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a poor duct system could actually cause new equipment to work more often than it should and shorten its life cycle. The experts at Cytech Heating & Cooling 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 could still be at the root of your home’s hot and cold spots. It’s commonplace for the ducts in a home to leak a bit over time. Experts like Cytech Heating & Cooling can inspect your ducts and let you know if they ought to be sealed. They may also find that your ducts aren’t leaking, but they’re not properly insulated. Fortunately, this is also a generally routine 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 experiencing hot and cold spots around your home. Improperly sized HVAC equipment could be the culprit. 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 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 correctly.

No matter what’s causing the hot and cold spots in your home, Cytech Heating & Cooling can help. Just give us a call at 956-630-3522 and we’ll help you figure it out and decide if you need air conditioning service, or any other types of HVAC service that can help you keep your home comfy.
