How to Get Your AC Ready for a Salt Lake City Summer

Salt Lake City summers are no joke. Temperatures regularly climb into the high 90s and triple digits, and a poorly prepared AC system will struggle — or fail — right when you need it most. A few hours of preparation in the spring can save you from an emergency AC repair call in the middle of a heat wave. Here is your complete spring AC preparation guide.

Step 1: Replace the Air Filter

This is always the first step. After a winter of running the furnace, your air filter is likely loaded with dust and debris. A fresh filter improves airflow, protects the evaporator coil from freezing, and helps your AC run at peak efficiency from day one. Use a filter rated MERV 8–11 for a good balance of filtration and airflow.

Step 2: Clean and Inspect the Outdoor Condenser Unit

Your outdoor unit sat through a Utah winter. Before running the AC:

  • Remove any debris from around and on top of the unit
  • Gently rinse the condenser fins with a garden hose (power off at the disconnect first)
  • Trim any vegetation within 2 feet of the unit
  • Remove any winter cover — a covered unit cannot operate safely

Step 3: Check the Refrigerant Lines

The insulated copper lines running from your outdoor unit to the indoor air handler should be fully insulated without gaps. Damaged insulation reduces efficiency and can lead to line freezing. If you see bare metal or deteriorated foam, call a technician to re-wrap the lines.

Step 4: Test the System Before Summer Arrives

Run the system for 15–20 minutes on a mild spring day when outdoor temperatures are above 60°F. Look and listen for:

  • Cold air coming from all vents within 5–10 minutes of startup
  • No unusual sounds — grinding, rattling, or squealing
  • AC blowing warm air where there should be cool air — if so, call for service
  • No ice forming on the refrigerant lines after 20 minutes of operation

Step 5: Schedule a Professional Spring Tune-Up

An annual professional AC maintenance visit is the most effective way to prevent summer breakdowns. A spring tune-up includes:

  • Measuring refrigerant charge and checking for leaks
  • Cleaning the evaporator and condenser coils
  • Testing and inspecting the capacitor and contactor
  • Lubricating the fan motor bearings
  • Checking electrical connections and testing for voltage irregularities
  • Calibrating the thermostat

A tune-up typically costs $80–$150 and can identify issues like a weak capacitor or low refrigerant before they become a total system failure on a 100-degree day.

Step 6: Check Your Thermostat Settings

Update your thermostat from heating mode to cooling mode and confirm the fan is set to AUTO. If you have a programmable thermostat, update your schedule for summer — setting temperatures higher when no one is home saves significant energy without sacrificing comfort.

Is It Time for a New AC Instead?

If your system is more than 12–15 years old and has needed multiple repairs, spring is the ideal time to consider AC replacement before summer demand drives up installation wait times. A new AC installation in Salt Lake City typically takes one day and will immediately reduce your energy costs.
