Are you concerned about rising energy costs in your home? Call HVAC experts from Premier Systems to optimize the energy efficiency of your air conditioner.


As a homeowner, it’s wise to look for ways to reduce your monthly expenses. As such, many homeowners wonder, “Is it more energy efficient to leave my AC on?” Understanding the factors that determine air conditioning costs can help you save on monthly utility bills.


An excellent way to improve your home’s energy efficiency is by scheduling AC maintenance services in Bozeman, MT. HVAC professionals from Premier Systems can tune up your system so it functions at the highest level.


What Happens When You Leave Your AC Off


When your AC powers off, outdoor temperatures and weather impact your interior spaces. During winter, this might not significantly impact indoor temperatures. However, your home can quickly become hot, humid, and uncomfortable during the summer.


You’ll more than likely want to crank the air after leaving your system off on a hot day. These sudden shifts in functioning actually cause more harm than good for your system’s efficiency. Because your air conditioner overworks to eliminate excess heat and humidity, it will cost more to operate.


When to Leave Your AC Running During the Day


Leaving your air conditioner on at a higher temperature throughout the day can significantly improve efficiency. The Department of Energy notes 78ºF as the optimal temperature for daylong functioning.


At this temperature, your air conditioner reduces interior humidity by sustaining a stable temperature. When you return home and turn the temperature down again, your system won’t have to overwork itself to compensate. Therefore, this practice reduces energy consumption and costs.


So, is it more energy-efficient to leave the AC on? In short, yes.


Potential Impacts of Indoor Humidity


Humidity levels above 60% can start to impact a home in negative ways. When your AC remains at 78ºF, you can avoid some of the adverse impacts of increased indoor humidity, including:


  • Warped wood floors and furniture
  • Increased chances of rot
  • Mold growth
  • Shrunk caulking
  • Condensation on windows
  • Potential damage to electronics


Other Ways to Optimize AC Energy Consumption


Beyond leaving your AC running all day, there are other effective methods to improve your unit’s energy consumption and temperature control. HVAC experts from Premier Systems can help you take advantage of these energy-saving strategies.


Install a Programmable Thermostat

Programmable thermostats allow remote temperature control and varied cycling throughout the day. As a result, if there are certain times you are never home, these thermostats automatically maintain the optimal temperature. Furthermore, these systems usually offer app-based control features, enabling you to change temperatures or fan speeds from anywhere.


Replace Air Filters

Your system’s filters eliminate contaminants in the air. Over time, though, they can become dirty and clogged.


Old air filters can significantly reduce energy efficiency. Replacing your filters is a simple and easy way to reduce energy costs and increase indoor comfort.


Utilize Ceiling Fans

While ceiling fans don’t add more cold air into a space, they help improve the circulation of your air conditioner. Thus, adding and using ceiling fans in your home can help areas cool down more quickly, reducing the need to overwork your unit.


Clean Your Outdoor Unit

Like your air filters, your HVAC’s outdoor unit can accumulate dust, dirt, and grime. Cleaning this essential component of your air conditioner allows smoother operation and lower energy consumption.


Improve Insulation with Weather Stripping

Weather stripping attaches to the cracks and crevices between doors and windows. Adding weather stripping to your property improves insulation while reducing the impact of outdoor temperatures.


Schedule Routine Maintenance for Your Cooling Systems

An essential component of minimizing your home’s energy use is receiving routine maintenance on all your comfort systems. When you call Premier Systems for HVAC maintenance, our technicians can tune up your system’s mechanical components and make minor repairs. These adjustments allow for more efficient operations.
