Most of our customers spent around $220 – $810* to repair their central Air conditioning system in 2023*. The total cost to repair a central AC unit can vary widely.

Most Central Air conditioning units require annual service before the AC is turned on in the summer. If your AC unit is not serviced or furnace filter changes are not on-time, AC units can freeze, overwork their compressor or fail altogether prematurely. As the unit ages (typically past the 10-year mark), part failure rates increase.

The most common issues for airconditioning units in Colorado are dirty furnace filters, dirty outdoor unit, low refrigerant, clogged indoor coil and capacitor failures.

The AC compressor is the integral part of your air conditioning system. Without the compressor, there is no cooling function in your air conditioning system. If the AC is showing any of the following symptoms, it should be checked out as soon as possible:

  • Warm air coming out of your vents even though the thermostat is set to cool
  • Buzzing, clicking or unusual noises coming from the unit
  • The outdoor unit starts leaking oil (dark thick brown liquid)

Is it worth fixing a 20 year old AC unit?

Whether or not an old AC system is worth replacing depends on the condition of the unit and the cost of the repairs. Typically, if the unit is old and in poor condition, or if the cost of repairs is high, it may be more cost-effective to replace the unit with a new one.

Air conditioning systems that use R22 refrigerant which are typically more than 15 years old are an exception; If your AC uses R22 and refrigerant has leaked out, you should definitely consider replacing it. For more information on R22 systems, click here.

Is it worth fixing an AC?

Whether it is worth fixing an AC unit depends on several factors, including:

  • The age and condition of the unit
  • The cost of repairs compared to the cost of a new unit
  • The energy efficiency of the unit
  • The level of comfort it provides
  • The availability of replacement parts for your specific model

If the unit is relatively new and in good condition, and the cost of repairs is not too high, then it may be worth fixing. However, if the unit is old and in poor condition, or if the cost of repairs is high, it may be more cost-effective to replace the unit with a new one.
