  • Replace any clogged air filters.
  • Reset the power to your unit.

Remember, modern systems have safety features like overflow switches that may shut down the unit to prevent damage. For comprehensive service, reach out to UniColorado to get your AC running smoothly again.

Hearing unusual noises from your AC? These sounds could indicate:

Denver AC Repair Costs

We charge $120 to visit your home & diagnose the issue. You’ll be provided with all options possible, upfront.

Most of our customers spent around $250 – $880* to repair their central air conditioning system in 2023*. The total cost to repair a central AC unit can vary widely. Multiple factors can cause an AC to break.

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.

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.

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.
