When to replace
Frequent breakdowns, systems older than about 15 years, R-22 refrigerant, rising power bills and rooms that never cool are all reasons to compare replacement with another repair. A technician can give you prices for both.
Sizing
A load calculation looks at the home's insulation, windows, orientation, shade and ducts. In the valley's dry heat, a correctly sized system runs long, steady cycles and keeps upstairs rooms comfortable.
AC with furnace or heat pump
Many Modesto homes have a gas furnace and a central AC. A heat pump can replace both the AC and much of the furnace's work, heating efficiently through mild valley winters. See furnaces and heating.
Efficiency
Higher-efficiency systems use less electricity for the same cooling. With long, hot summers, the savings add up faster here than in cooler parts of the state.
Title 24
California's energy code usually requires a permit for an AC or furnace replacement, and often requires duct leakage testing with third-party verification. See Title 24 and duct testing.
Ducts
Many older homes have leaky or undersized ducts in hot attics. Sealing or replacing them alongside a new system protects your investment.
Placement
Outdoor units in shade with good airflow work more easily. Keep them away from dryer vents and dusty areas.
