Littlerock homes
Littlerock is a small unincorporated community: about 1,400 people in roughly 400 homes, by the Census Bureau’s latest five-year survey (Census Reporter). Nearly all are single-family houses, and the typical home was built in the early 1980s. With a community this small the figures carry a wide margin, but the picture is clear: older single-family homes, out where the wind and sun hit hardest.
A system from the 1980s or 1990s that is still running may use R-22. The EPA says no new R-22 has been made or imported since January 1, 2020; it can still be serviced with recovered refrigerant, but a big leak is often the point to replace. ENERGY STAR treats an air conditioner more than 10 years old as a candidate for replacement. See AC repair and replacement.
Filters, coils and dust
The windier part of the year runs from November into June (WeatherSpark, Palmdale averages), and out in the open the dust gets into everything. ENERGY STAR says to inspect, clean or change filters once a month; here, look again after every windy stretch. The EPA suggests at least a MERV 13 filter if your system’s fan and filter slot can handle it.
Outside, keep the condenser clear of tumbleweeds and drifted dirt, since a coil packed with dust can’t shed heat and runs hot all summer. A spring and fall maintenance visit cleans the coils, and a whole-home air cleaner catches more of the dust before it reaches the rooms.

Permits in Littlerock
Littlerock is unincorporated Los Angeles County, so permits for a new air conditioner, heat pump, furnace or mini-split come from LA County Public Works, filed through EPIC-LA. The contractor doing the work pulls the permit.
