If you find that you have hot and cold spots through your Tucson home, you’re not alone. This is a relatively normal issue. While it may seem like a big issue, the good news is that the common causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most common 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
- 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 means you’re able to determine the air temperature in each zone. The system is composed of multiple thermostats that control dampers in the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers to match up with the thermostat's settings. This may be the key to keeping that one cold bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when you utilize it with a programmable thermostat, zoning could 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 room that needs heated and cooled, or it’s poorly designed. We find this is fairly commonplace 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 match homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a bad duct system could actually cause new equipment to work more often than necessary and shorten its life. The pros at Ambient Air 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 designed and sized properly 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 become leaky over time. Pros like Ambient Air can look at your ducts and let you know if they should be sealed. They might 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 noticing hot and cold spots through your home. Improperly sized HVAC equipment may be the cause. A system that is too small has to work 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.
