Beat the Summer AC Surge: An 8-Point Pre-Heat Checklist

Texas doesn't ease into summer. One week it's mild, the next it's 100 degrees for a month — and an HVAC system that limped through spring fails on the hottest afternoon, with a resident on the phone and a technician two hours out. The heat is predictable. The emergency calls don't have to be.

Why reactive cooling is the expensive kind

A summer no-cool is the most expensive way to cool a unit. Emergency dispatch, after-hours rates, a frustrated resident, and a repair that lands right on top of peak turn season when crews are already stretched thin. Multiply it across a portfolio and a few weeks of heat can dent a maintenance budget and your resident satisfaction in one stroke. Most of it is preventable. A dirty coil, a clogged condensate line, a weak capacitor, a low charge — these show up weeks ahead if someone looks. Run the units before the heat runs them.

The 8-point pre-heat checklist

Run this on every system before the first 100-degree week:

• Coils — clean the condenser and evaporator coils. Dirty coils are the number-one cause of summer capacity loss.

• Filters — replace, and confirm the right size and MERV. A collapsed filter starves airflow.

• Refrigerant — check the charge and inspect for line leaks. Low charge means warm air and a straining compressor.

• Condensate line and pan — flush the drain and clear the pan. A clogged line trips the unit or floods a ceiling.

• Capacitor and contactor — test and replace anything reading weak before it fails under load.

• Thermostat — verify calibration and programming; move to smart thermostats where it makes sense.

• Airflow and vents — confirm supply and return are clear. A blocked return overworks the whole system.

• Outdoor unit — clear debris, check the disconnect, confirm the fan runs clean.

Triage: not every call is an emergency

Even with a clean pre-heat pass, some calls will come. A simple split keeps crews where they matter most and keeps Property Managers out of the "everything is urgent" trap:

• True emergency (same day): full no-cool in extreme heat, vulnerable residents, or water intrusion from a condensate failure.

• Urgent (24–48 hours): weak cooling, intermittent operation, one room not keeping up.

• Deferrable (scheduled): noise, minor thermostat quirks, cosmetic issues.

Sort the inbound against those three lines and the genuine emergencies get same-day attention while the rest batch into planned visits. The pre-heat pass is what shrinks that emergency column in the first place. Every system you touch in June is one that doesn't call you in July.

Two failures you can see coming

A rooftop condenser caked with cottonwood drops a fifth of its capacity the first 100-degree day — a 20-minute cleaning in spring. A condensate line that backs up stains a downstairs ceiling — a $40 flush that becomes a drywall-and-paint job. Both are on the checklist for a reason: the cheap version of the fix has an expiration date, and it's the first hot week.

Walk into summer on the record

A preventive pass is only as good as your proof it happened. 360's HVAC work is licensed, photo-documented, and tracked in the portal — so you verify it unit by unit instead of taking it on faith. You see what was checked, what was fixed, and what to watch.

Book your pre-heat HVAC pass before the first 100-degree week. Schedule with your 360 account manager and head into summer with fewer surprises.
