Lancaster Commercial HVAC Questions & Answers
How fast can your technicians arrive for a commercial AC failure in Lancaster?
Working Class HVAC offers priority commercial dispatch. Because our primary headquarters is right on West Ave L in Lancaster, we can dispatch emergency commercial technicians within 45 to 90 minutes anywhere in Lancaster or Palmdale.
Can you repair existing rooftop equipment without forcing an immediate replacement?
Absolutely. As our name implies, Working Class HVAC was built on honest blue-collar tradesmanship. We do not push unnecessary unit replacements. If an RTU can be reliably repaired by replacing a contactor, blower bearing, capacitor, or expansion valve, we will provide you with an upfront flat quote to get it running immediately.
What is included in a quarterly commercial maintenance agreement?
Our commercial maintenance visits include replacing pleat air filters (MERV 8 or 13), checking belt tension and pulleys, cleaning condenser coils with non-acid desert wash, checking operating pressures and subcooling/superheat, measuring compressor and fan motor amp draws, tightening electrical connections, and ensuring your Title 24 economizer operates smoothly.
