When it already costs you money to use your HVAC system to feel comfortable, having hot and cold spots consistently in your home can be frustrating. What is causing these uneven temperatures to occur? Is it a problem with your HVAC system? What's the solution?

Homes with uneven temperatures (hot and cold spots) are much more typical than you might think. Below are a few of the most common explanations for why this occurs as well as some helpful solutions.

Different Levels of Sun Exposure

Some areas of your home receive more direct sunlight than others, and this can make these areas noticeably warmer. If these rooms are too warm for your comfort, you can consider these simple but effective solutions to make the temperature more consistent with the rest of your home:

  • Run the ceiling fan.

  • Install blinds or an awning outside.

  • Tint the windows.

Rising Heat

The upper stories of a home are almost always going to be hotter than the bottom floors due to the way heat rises. A family member who spends a lot of time upstairs might be turning your thermostat down low to try to make your home’s second story cooler, while those spending time downstairs are just about ready to freeze. To remedy this, look into installing zoning for your central HVAC system.

Zoning refers to the division of an interior into several temperature "zones," each of which can be fine-tuned with a separate thermostat. Zoning will not work on single-speed comfort units because zoning involves directing more airflow or less airflow to each zone based on occupants' needs. Systems with two or more speeds, called modulating systems, are the best option.

Blocked Vents or Leaking Ductwork

If the air vents to your room are blocked by a rug or furniture, it may feel like your HVAC system isn’t working at all. Check for any blocked vents in your home! If you feel weak airflow out of a particular vent, then there may be leaks in your ductwork. An HVAC technician can solve this problem by sealing the leaks for you or replacing any part of your ductwork that is damaged beyond repair.

An Undersized or Oversized HVAC Unit

Some think that bigger is better with regards to HVAC systems. The reality, though, is that oversized units heat and cool too quickly, creating uneven temperatures. On the other hand, undersized products will struggle to put out adequate warm or cool air, leading to hot and cold spots around your house. When choosing an HVAC system for your home, it’s wise to involve an HVAC professional in the purchase so that they can advise you on the optimal system size for your heating and cooling needs.
