Reasons the Upstairs is Too Hot
Sometimes, the upstairs level of the home can become inexplicably hot, causing homeowners to turn up the air conditioning and increase their electricity bill. Several factors can cause this sudden temperature rise, but it's a problem that's easily fixed with expert assistance. Consider why the upstairs level of a home may become too hot and how the problem can be resolved.
Clean the air filters
Changing the air filters in the home is essential. Filters clogged with dirt, dust, or pet hair reduce the circulation of the conditioned air through the home. A dirty filter can also strain the system and make it work harder than needed. Experts typically recommend replacing or cleaning air filters every 4 to 6 weeks, depending on the air quality in the home.
Check the insulation
Check the insulation around windows and doors on the home's second floor. Even the most minor gaps and cracks can let in hot summer air. While these little cracks may not seem like much, they add up to a significant amount of cold air lost over a day. Proper insulation in the attic can also substantially reduce the amount of heat that becomes trapped on the second floor. Installing exhaust fans or an attic fan can also help circulate and remove as much hot air as possible.
Consider AC unit size
Hot air rises, so as the temperature outside causes the indoor temperature to increase, all the hot air goes to the highest point in the house. If the AC unit is located on the first floor, it has to work harder to push cold air to those upper floors. One of the most important things to consider is whether the unit is the right size for the home. Many homeowners are surprised to learn that the unit installed initially with their home is too small to cool it adequately.
Check the ductwork
Faulty, leaking, or improperly installed ductwork can be to blame for the hot upstairs temperatures. If the ductwork hasn't been inspected in the past year, it's best to call a professional to assess if this area is the cause of the issue.
Inspect the roofing
The roof is the ultimate culprit when it comes to heating the upstairs. Heat travels through the roof and into the attic, and unless the roof is designed to reflect the sun or is protected from it, the shingles absorb the sun's heat. This is great for keeping the roof free from the weight of the snow in the winter but not so great for cooling things down in the summer. Call a professional to determine if the roof is the cause of sweltering upstairs temperatures, and they can make recommendations for the next steps if necessary.
Homeowners should not ignore an uncomfortably hot upstairs, as it's unpleasant for home residents and can cause the electric bill to rise substantially. Consider these factors if the upstairs becomes too hot, and always contact a professional to help assess the issue and resolve it quickly.
