What temperature should I keep the house while on vacation?

• <div><p>Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the <a href="https://www.angi.com/articles/best-ac-temp-for-energy-efficiency.htm">best AC temperature for energy savings</a> is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive. </p></div>

Is it better to repair an AC or replace it?

• <div><p>Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around <b>15 years</b>, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">replacing the AC unit</a> rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.</p></div>

Heating and Air Conditioning questions, answered by experts

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.
