The cost of inspecting an AC unit depends on its size, type, and age. Typically, an air conditioner inspection costs about $100 to $150, not including any repair costs. Note that prices may be higher if any components need replacing or the AC has been idle for a long time.
Some of the main tasks an HVAC professional will perform during an AC system inspection include:
✓ Checking the thermostat settings
✓ Examining the condenser and evaporator coils
✓ Testing the air blower
✓ Inspecting the electrical connections
✓ Checking refrigerant levels and pressure readings
✓ Checking safety devices and controls
✓ Providing repair or replacement recommendations
During the inspection, the technician may also undertake tasks such as cleaning the motor and other system components, lubricating the moving parts, or replacing air filters.
Furnace
Furnaces are essential for keeping homes warm and cozy in the cold months, but they need regular checkups to keep running smoothly. A typical furnace inspection will range in cost from $75 and $150, depending on the furnace type, your home’s size, and other factors.
