A weak cooling system often points to low refrigerant from a leak, dirty coils or filters restricting airflow, or a failing compressor. Our HVAC technicians will inspect the unit, locate and repair any leaks, recharge the system to proper levels, clean or replace filters and coils, and determine whether the compressor or electrical controls need attention. Prompt professional AC repair ensures your cooling system returns to peak performance and prevents further damage.

Rattling, grinding or screeching sounds usually indicate loose screws, worn fan bearings or lack of lubrication in the compressor. Other noises like whistling or banging can come from air leaks in ductwork or failing motors and should be checked immediately. Continuing to run a noisy unit risks costly damage – our cooling repair specialists diagnose the issue, tighten components, lubricate moving parts and replace damaged motors or compressors as needed.

We consider the system’s age, repair history, and efficiency before recommending repair or replacement. If your air conditioner is more than ten years old or the cost of repairs multiplied by the unit’s age exceeds about $5,000, replacement with a newer high‑efficiency model may be smarter. For newer systems (under five years) or minor issues, a professional AC repair can extend the unit’s life and save on upfront costs.

It’s best to schedule a professional tune‑up at least once a year – ideally in the spring before peak cooling season to clean coils and filters, check refrigerant levels and electrical controls, and verify safe operation. Regular maintenance improves energy efficiency, catches small issues early and helps your air conditioner last 10-15 years. Our HVAC maintenance plans make it easy to keep your AC running smoothly and avoid unexpected cooling repairs.
