Atlanta’s year, by which system is working hardest

Average daily high for each month. Blue months lean on your air conditioner, orange months on your heat. The two mild months in between are the easiest time to get a system looked at, before it’s carrying a full load.

April: before the AC carries summer

A cooling check before May means a weak capacitor or low refrigerant shows up on a 73° day, not the first 90° one.

October: before the heat comes on

Firing the furnace or heat pump once in fall shows whether it lights, runs and heats cleanly before November’s cold nights.

What’s going on at your house?

Start from what you’re noticing. Tell us that when you call and we’ll take it from there.

  • AC

    The air is running but not cold

    Often refrigerant, a failing capacitor, or a dirty coil. Cooling repair.

  • HEAT

    The heat won’t come on

    Ignition, thermostat, or a safety switch shutting it down. Heating repair.

  • AIR

    Some rooms never get comfortable

    Usually airflow: ductwork, returns, or a system sized wrong for the house.

  • SYS

    It’s old and the repairs keep coming

    Time to talk through repair versus replacement, honestly.

Before you call

Three things that make the first conversation faster.

  1. Note what it’s doing

    No air, warm air, a noise, a smell, short cycling. When did it start?

  2. Check the thermostat and breaker

    Fresh batteries, correct mode, and the HVAC breaker not tripped. Sometimes that’s the whole fix.

  3. Find the label on the unit

    The brand and model number on the outdoor unit or furnace tell us what we’re working on.
