If you discover that you have hot and cold spots throughout your Rochester home, you’re not alone. This is a fairly regular occurrence. While it may seem like a major issue, the good news is that the common 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:
- 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 splits your home into separate areas, known as “zones,” and means you can determine the air temperature in each zone. The system involves multiple thermostats that operate dampers in the ductwork of your forced-air system. The thermostats constantly read the temperature of their designated zone, then open or close the dampers to meet the thermostat's settings. This could be the key to keeping that one frozen 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 experience hot and cold spots simply because their home’s duct system isn’t sized correctly for the space that needs heated and cooled, or it’s improperly designed. We find this is pretty normal in homes that were built before a lot of today’s tools and training were available. 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 poor duct system could actually cause new equipment to work more frequently than needed and decrease its lifespan. The experts at Brogan Heating & AC 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 common for the ducts in a home to become leaky over time. Professionals like Brogan Heating & AC 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 properly insulated. Fortunately, this is also a generally 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 noticing hot and cold spots around your home. Improperly sized HVAC equipment may be the culprit. A system that is too small has to work 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 properly.
No matter what’s the culprit of the hot and cold spots in your home, Brogan Heating & AC Inc can help.
