Our Air Conditioner Maintenance Checklist

Our licensed comfort specialists follow a detailed checklist that focuses on detecting minor issues before they become significant ones and mitigating problems entirely.

Clean Dirty Coils

A buildup of dirt on AC coils makes it difficult for the unit to absorb and remove heat, resulting in inefficient operation and higher monthly energy bills.

Replace Old Air Filters

Dust and dirt on your air filter won’t allow your AC unit to function adequately and can cause allergens to build up, making breathing a challenge for everyone.

Check Condensate Drains

While clogged lines are a common cause of air conditioner malfunctions, they can create severe problems with your system. Fortunately, it’s an easy problem to fix for our professionals.
