The Aurora, CO HVAC Maintenance Calendar — What to Do Each Month
If you only remember two dates from this page, make them: cooler down before the first freeze, and furnace serviced before the first cold snap. Both land in October in Aurora. Everything below is the full year around them.

| August | Book fall appointments now, before freeze-week demand | Free |
| September | Ideal month for cooler shutdown — open schedule, best weather | $150 |

| December | Filter check, CO alarm test, keep the furnace area clear | Free |
The two visits that matter
Fall: cooler shutdown — $150
Drain the pan and the supply line, pull the pump, clear scale, cover the unit, seal the register. The deadline is the first hard freeze, which on the Front Range usually lands overnight between late September and mid-October.
Fall: gas furnace service — $150
Filter, burners, flame sensor, ignition, heat exchanger, blower, flue, gas pressure, airflow, thermostat cycle. The deadline is the first cold snap, which is usually the same week as the freeze.
Booked together on one visit: $200 — you save $100.
Free monthly habits that extend system life
- Filter check, once a month during heating season. A clogged filter is the most common cause of an overheating furnace.
- Register and vent clearing. Furniture and rugs over returns force the system to work harder.
- Clearance around the furnace. No paint cans, boxes, or storage against the cabinet.
- CO alarm test. Test the button and check the replacement date; alarms expire.
- Listen and smell. A new noise, a sooty smell, or a yellow flame is a call, not a wait-and-see.
Why booking in August and September pays
Schedule capacity is the hidden variable in HVAC pricing. In September, a cooler shutdown is a scheduled visit. In the 24 hours after a freeze warning, the same visit is competing with every other homeowner in the metro who did not book. Same work, same price, very different stress level.

Do I need a spring cooler start-up?
It is the mirror of the shutdown: pads, pump, water line and belt get checked so the first hot week is not the week you find out something aged out over winter.
How much does a spring start-up cost?
Ask when you call — many of our customers book shutdown and start-up together so both are on the calendar at once.
What months are worst for emergency calls in Aurora?
The first freeze week in October and the first sustained cold snap in November, plus the first 90-plus day stretch in June.
Can I do any of this myself?
Filter changes, register clearing and CO alarm testing — yes. Draining a cooler supply line, inspecting a heat exchanger, and anything involving gas — no.
