HVAC Services Los Angeles CA | Call United Heating & Air Conditioning

In Los Angeles, where systems run frequently, we recommend professional maintenance twice a year—once before the cooling season and once before the heating season. This service includes cleaning or replacing your air filters, which is crucial for preventing clogs that reduce efficiency and strain the system. Our regular check-ups also help spot early signs of outdoor coil corrosion from our coastal and urban air, allowing us to address it before it leads to major repairs.

Our installation process begins with a detailed assessment of your home's size, layout, and specific needs to ensure we recommend the right system for Los Angeles's climate. Our licensed technicians handle everything from removing your old unit to installing the new system, including precise refrigerant charging and ductwork evaluation. We ensure proper permitting and a final inspection, so your new HVAC operates efficiently and reliably for years to come.

First, check simple fixes like your thermostat settings and circuit breaker. If the issue persists, give us a call. Our repair technicians are EPA and NATE-certified and can diagnose problems ranging from refrigerant leaks to electrical faults. We service all major brands and provide clear explanations and upfront pricing. For urgent needs, we offer prompt scheduling to restore your comfort quickly.
