That position shapes the HVAC work we do here: - **Wind and dust.** Santa Ana winds funnel through the passes north of Sylmar and coat condenser coils with dust and debris. A clogged outdoor coil makes the compressor run hot; rinsing it is part of our tune-up. - **Wildfire smoke.** The 2008 Sayre Fire burned through Sylmar, and smoke from foothill fires can reach homes during fire season. Tight returns and better filters keep it out of the house. - **Larger lots and older homes.** Many properties have detached rooms, guest units or horse barns, and older homes with original ductwork in the attic. Sylmar is in the City of Los Angeles (LADBS permits, LADWP power). Technician servicing an outdoor condenser in Sylmar Furnace control board under repair ## Heating and furnace repair in Sylmar Winter nights at the foot of the mountains can get cold, so a working furnace matters in Sylmar. We repair gas furnaces, heat pumps and wall heaters: no heat, short cycling, a pilot or igniter that will not light, a blower that runs without warm air, and inducer motors that hum or squeal.

Technician installing an outdoor AC unit ## AC installation in Sylmar When an older Sylmar system is past repair, the replacement should be sized with a load calculation, with the coil matched to the new outdoor unit and the ductwork checked. A heat pump replaces the AC and the furnace's heating in one system; ductless mini splits suit guest units and detached rooms without ducts.

Air duct installation, Pacoima ## Sylmar AC repair questions How often should a Sylmar condenser be cleaned?At least once a year before summer, and again after a windy stretch or a nearby fire if you see dust or ash on the fins. A clean coil lowers the pressure the compressor works against. Do you repair HVAC in guest houses and detached rooms?Yes. We repair the central system and ductless units in guest units, and can add a mini split to a detached room that has no heating or cooling. Is emergency AC repair available in Sylmar and Pacoima?Yes, 24/7 emergency AC repairs are available in both.
