Winter Heating Tips to Avoid Emergency AC Repair


As winter sets in, the debate over the most efficient way to manage your home heating becomes a hot topic. Finding the right balance can keep you warm and help you avoid emergency AC repairs. 

At AC Designs, our expert HVAC technicians are here to provide expert advice on how long your heat should be running, signs of an overworked AC unit, and the ideal thermostat settings.

When Should My Heat Be Running?

During the winter months, finding a balance between heating your home efficiently and minimizing costs is essential. Turning off the heat when leaving the house may seem like a money-saving move, but the experts at AC Designs suggest a different approach. 

Many people believe it takes more energy to reheat your home than to maintain a constant temperature. However, according to the U.S. Department of Energy, lowering your thermostat by 10 to 15 degrees for eight hours a day can save you up to 15 percent on heating costs annually. 

Lowering your thermostat rather than turning it off ensures that your HVAC system doesn’t have to work extra hard to restore the temperature. Make this a habit each day during the winter months before heading to work to protect your unit and your wallet. 

Is My Unit Being Overworked?

Are you wondering if your HVAC unit is pulling more weight than it should? An overworked AC system can present itself in many ways, impacting your comfort and energy bills. Keep an eye out for these warning signs:

Increased Energy Bills

A sudden spike in your energy costs may indicate that your HVAC system is working harder than necessary.

Uneven Heating

If some rooms in your home are warmer or cooler than others, it could be a sign of an overworked HVAC unit struggling to maintain consistent temperatures.

Frequent Repairs

Regular breakdowns and the need for frequent emergency AC repairs are clear indicators of an HVAC system under stress.

Dusty Home

An overworked system may struggle to filter and circulate the air in your home properly, leading to a dustier environment and the need for frequent indoor air quality services.

Strange Noises

Unusual sounds coming from your HVAC unit can be a sign of mechanical strain and potential issues.


Water leaks around your HVAC unit or surrounding areas could result from an overworked system.

What Temperature Should I Set My Thermostat To?

Choosing the right thermostat setting is the key to maintaining a comfortable and energy-efficient home. During winter, the U.S. Department of Energy recommends setting your thermostat to 68°F when you’re home.

Similar to leaving a door or window cracked on a cold day, setting your thermostat above 70°F can cause the heat in your home to escape quickly. You’ll find yourself using more energy to maintain the warmth you prefer.

If you’re used to a toastier home in the winter, try gradually nudging your thermostat down to 68°F. This allows your body and home to adapt, helping you find a sweet spot where you’re comfortable while maximizing energy efficiency.
