Frequently Asked Questions
How long does a typical residential air conditioning system last?
A well-maintained air conditioner generally lasts between 15 and 20 years. Once a system passes the 15-year mark, its efficiency drops significantly, and internal components become much more susceptible to major mechanical failures during periods of heavy use.
What are the most common AC replacement warning signs?
The most frequent indicators include weak airflow from your vents, blowing warm or lukewarm air, unusual noises like grinding or squealing, frequent short-cycling, and a sudden, unexplainable increase in your monthly energy bills.
Is it better to repair an old air conditioner or replace it entirely?
If your system is over 10 to 12 years old and requires a repair that costs more than half the value of a new system, replacement is generally the more cost-effective option. New units offer much higher energy efficiency ratings, which helps lower your monthly bills.
Why does my air conditioner seem to struggle specifically during a heatwave?
Extreme outdoor temperatures force your system to run longer to maintain your indoor settings. If the unit has underlying issues, such as a worn compressor or dirty coils, the added strain of a heatwave will amplify these weaknesses and cause a breakdown.
How can I improve the efficiency of my current cooling system?
Regularly changing your air filters every 30 to 90 days, keeping the outdoor condenser unit free of debris, and scheduling annual professional maintenance are the best ways to maximize your system’s efficiency and extend its overall lifespan.
