Three articles that cover what most homeowners ask us about their HVAC system — how often to service it, how to recognize a furnace problem early, and whether a heat pump is the right pick when the current unit finally gives out. Written by Pure Eco technicians for Southern California homes.

How often should I service my AC?

Once a year, ideally in spring — plus a filter change every 60–90 days. Here's what an annual tune-up covers and how skipping it shortens the life of the system.

Cluster FAQ

How much does a typical HVAC service call cost in Southern California? +

A diagnostic service call in the LA / San Fernando Valley market typically runs $75–$150. A full annual tune-up is usually $99–$199 depending on the number of units. Repair costs vary by part — a capacitor is under $250 installed; a full compressor replacement can be $1,500+.

Is a heat pump right for a Southern California home? +

Almost always, yes. SoCal winters rarely dip below 40°F where heat-pump efficiency starts to drop, so a modern variable-speed heat pump gives you cooling and heating in one unit and typically operates cheaper year-round than a gas furnace paired with straight AC.

How long should an AC last in SoCal? +

12–17 years is typical for a well-maintained system. Coastal salt-air homes tend to sit at the low end due to corrosion; inland homes with clean maintenance history routinely hit 15+ years. Skipping annual service is the #1 predictor of an early failure.
