AC maintenance and coil cleaning
Desert dust is the quiet enemy of an outdoor coil. A spring visit clears it and catches worn parts while the weather is still mild.
Why dust matters here
The City of Henderson warns that dust clouds are common during wind storms (city desert living tips). Every gust packs a little more grit into the thin aluminum fins of the condenser coil. The coil has to shed the heat pulled from the house, and a coated coil sheds it slowly, so pressures and running temperatures climb.
Gravel yards, block walls and side-yard placement make it worse: air moves less freely and debris collects along the base of the unit.
What a cooling visit usually covers
- 01
Outdoor coil cleaned
Rinsed from the inside out with the power off, so dirt leaves the way it came in.
- 02
Electrical checks
Capacitor values measured, contactor inspected, connections tightened.
- 03
Refrigerant performance
Pressures and temperatures read against what the equipment expects.
- 04
Indoor coil and blower
Checked for dirt and airflow, since a dirty indoor coil cuts capacity too.
- 05
Condensate drain
Flushed and checked for flow, including the safety switch on an attic pan.
- 06
Thermostat
Calibrated against a separate thermometer and checked for the right settings.
Between visits
NV Energy's summer advice includes keeping filters clean (NV Energy tips). In a dusty season, check a standard filter monthly; the right interval depends on the filter and the house. Keep shrubs and stored items a couple of feet back from the condenser so it can breathe.
The furnace on the same visit
A gas furnace sits idle most of the year here, which is no reason to skip it. Southwest Gas recommends having gas appliances serviced every year by a trained professional and keeping at least three feet clear around the furnace (Southwest Gas safety page). Many homeowners book the heating check in the fall and the cooling check in spring.
Questions
Can I hose off the coil myself?
Gently, with the power off at the disconnect and no pressure washer. Bent fins and wet electrical parts are the risks, and a contractor's cleaning also covers the indoor side.
How often should a system be serviced?
Once a year for cooling is common here; gas furnaces get their own yearly check.
