Too Warm or Too Cold? It Could Be Your HVAC System

This entry was posted in Air Conditioning on by .

Just like Goldilocks and her porridge, you want the temperature in your home to be just right. Yet, it’s a common problem to have one room considerably colder or hotter than the others. The knee-jerk reaction to address this problem is to adjust the thermostat. Yet, this often makes the problem worse by making rooms even colder or hotter. Instead, you may want to consider the following factors:

Inadequate Insulation

Often rooms that lack sufficient insulation, such as additions or attics, can have temperature differences. If the temperature shifts from extreme cold to extreme heat with the seasons, insulation is often the problem and can be easily corrected by adding insulation to walls and above the ceiling.

Poor Duct System Design

According to the US Department of Energy, the average HVAC duct system is only about 60 percent efficient. This means air can’t flow throughout your system and home efficiently. Consequences of this problem include hot and cold spots, along with more wear and tear on your air conditioner, poor air quality and unbalanced air pressure. Common design issues include undersized ductwork, the equipment being too far from the spaces being cooled and sharp bends that decrease air flow.

Duct Leakage

Ducts that are incorrectly sealed or supported can also create temperature variations. A single leak can cause cooled or heated air to be distributed into the walls or above the ceiling, instead of into rooms.


Whether you have single or double-paned windows, the Arizona sun can be relentless, causing rooms to heat up quickly during certain times of the day. If your temperature problem seems to follow the sun, it may be well worth it to invest in some quality sun shades or screens.
