Energy efficiency is a major concern for homeowners due to high cooling costs, increasing demand for SEER 16+ systems and smart thermostats.

Get answers to common questions about hvac services in Ontario, California.
For a standard single-family home, a full AC replacement in Ontario typically ranges from $5,000 to $12,000+, depending on system size, efficiency rating (SEER), and installation complexity. Ontario's hot, dry summers make a properly sized and efficient system crucial for comfort and energy savings. Be sure to get multiple itemized quotes that include removal of the old unit, new refrigerant lines, and compliance with California's strict refrigerant and electrical codes.
The absolute best times are during the mild seasons of spring (March-May) and fall (September-November). Scheduling service during these periods ensures your system is ready for the intense summer heat, and you'll find greater technician availability and potentially better pricing than during the peak summer demand crisis. Avoid waiting for the first major heatwave, as service delays are common and systems are under maximum stress.
Always verify the contractor holds a valid, current California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license with the CSLB. Choose a local company with strong reviews and a physical address, as they understand our specific climate challenges like dry heat and seasonal Santa Ana winds. They should provide a detailed, written estimate and clearly explain the need for proper system sizing (Manual J calculation) for your home.
This is a very common issue in Ontario's summer. It could be a repairable problem like a dirty air filter, low refrigerant charge, or a failing capacitor. However, if your system is over 10-15 years old, is using R-22 refrigerant (phased out by EPA), or has a failing compressor, replacement is often more cost-effective. An honest technician can perform a full diagnostic to determine if repair makes sense or if a new, more efficient system would provide better cooling and lower energy bills.
