What is causing hot and cold spots in my home or business?

Vent Size and Placement

One of the most simple fixes to hot and cold spots is to adjust vents and registers. All vents and registers should be open and unblocked so it is important to check under rugs and behind furniture.

Improperly Sized Units

A unit that is too small might not have enough power to properly heat or cool your environment. A unit that is too large can cycle on and off so often that it becomes inefficient.


The size and design has a large effect on the air circulation throughout your environment. Ductwork issues are common in older homes that were built without knowledge of these requirements. Besides causing hot and cold spots, these issues can also require more energy from HVAC units, which reduces their lifespan. If ductwork is leaking, it can further reduce efficiency.


Problems with your home or business’ temperature can be caused by air leaking through walls, doors, and windows. Insulation is a barrier between your environment’s interior and exterior and should also surround air vents to reduce leaks and improve temperature control.


The performance of your thermostat has a significant effect on your environment’s temperature. It is important to place the thermostat in a central area so that it gets an accurate temperature reading. Additionally, outdated thermostats might be in need of replacements.
