If you discover that you have hot and cold spots in your McMurray home, you’re not alone. This is a pretty common problem. While it can seem like a big concern, the good news is that the typical causes of hot and cold spots are normally easy to fix with a simple air conditioning service. The most routine causes for hot and cold spots are:
- Zero zoning or improper zoning
- Poorly designed or ineffectively sized duct systems
- Leaky or inefficiently insulated air ducts
- The wrong size of HVAC equipment
Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you can set the air temperature in each zone. The system is composed of multiple thermostats that run dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their assigned 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 smoldering 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 room that needs heated and cooled, or it’s improperly designed. We find this is pretty normal 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 match homeowners’ expectations if the duct system isn’t letting it do its job. In fact, a bad duct system could actually cause new equipment to work more often than it should and shorten its lifespan. The experts at Kowalski Heating, Cooling & Plumbing 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 could still be the source of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Pros like Kowalski Heating, Cooling & Plumbing 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 fairly easy 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 could be the culprit. 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 handle 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 correctly.
