How low can you turn your AC down before it causes damage? Many homeowners mistakenly calibrate their thermostat settings too low, reducing the service life of their appliances and causing spikes in their utility bills. 


You can avoid these problems by considering the information below. Bozeman's reliable AC maintenance contractors discuss the preferred thermostat setting, and common problems you may experience when lowering your thermostat.

How Low Is Too Low?


Every air conditioning system is different. However, you can follow a few strategies to improve the reliability and energy efficiency of your unit during the summer. For example, HVAC specialists recommend setting your thermostat no lower than 20 degrees the outside temperature. 


Suppose the outdoor temperature in your area is a blistering 90 degrees Fahrenheit. It’s probably best to keep your thermostat between 70 and 80 degrees Fahrenheit to prevent stress on your unit. 


Problems You May Encounter When Setting the Thermostat Low


Ignoring the advice above could cause a wide range of HVAC issues. Here are a few things to look out for when calibrating your AC unit:


  • Dehumidification Problems: Your air conditioning unit dehumidifies the air as it cools your home. Setting the temperature too low can cause underperformance issues and reduce its ability to eliminate moisture in your air.
  • Component Malfunctions: Overworking your blower fan may cause it to malfunction over time. Depending on the size of your air conditioning unit, this problem could require expensive repairs. 
  • Refrigerant Leaks: Your refrigerant coils may produce too much condensate at low temperatures, resulting in frozen components. Freezing AC units will produce less cool air and may shut down unexpectedly.
  • High Energy Bills: The harder your HVAC system works, the more money you should expect to pay on your monthly utilities.


How low can you turn your AC down when you are away from home? Does raising the temperature prevent these issues? In most cases, keeping your thermostat closer to the outdoor temperature while you are away can prevent or delay these issues significantly.


Ask a professional, like those at Premier Systems, which solution is right for your AC model.


How to Improve Indoor Temperature Control


Turning your thermostat down may not always be the most practical solution to improve your indoor comfort. You can save money on your utilities and prevent HVAC over performance issues with the following tips:


  • Use portable fans and cooling appliances while your AC runs
  • Clear mold, ice, and debris away from your outdoor unit
  • Install a smart thermostat to monitor changing weather conditions and adjust accordingly
  • Reduce obstructions in your air ducts for better temperature regulation
  • Replace air filters every three months for optimal cool air flow
  • Monitor your thermostat regularly to avoid overspending on cool air
  • Invest in a new air conditioning system with better energy efficiency ratings (SEER)


Is a Replacement HVAC System Necessary?


Sometimes, irreparable damage can prevent your AC unit from producing enough cool air to achieve your desired indoor temperature. In this case, a new installation may be necessary to save you from the summer heat.


Most new air conditioning systems will list recommended thermostat settings on the product box or user manual. Don’t ignore these metrics. Lowering the temperature settings below the model’s power capabilities could cause unnecessary damage. 


A licensed and insured technician can help if you aren’t sure what size model or SEER rating you need for your home. They will inspect your vent system and count rooms in your home to ensure that you get the best circulation throughout your property.
