What's in an AC Tune-Up? The Spring Maintenance Checklist for Maryland Homes

By Bens Air Conditioning  |  Serving all of Maryland

Maryland summers are hot and humid, and by August your air conditioner has run more hours than your car engine. A spring AC tune-up is the cheapest insurance against a July breakdown.

What a real tune-up includes

• Refrigerant charge check (low charge = high bills and frozen coils)
• Outdoor condenser coil cleaning
• Capacitor, contactor and wiring test
• Condenser fan and blower motor amp draw
• Air filter replacement
• Condensate drain flush to prevent water damage
• Thermostat calibration
• Temperature split test across the indoor coil
• Ductwork and airflow check

Why it pays for itself

A dirty coil alone can cut efficiency by 20-30%. Catching a weak capacitor in April costs a fraction of an emergency call in a heat wave. Most manufacturers also require annual maintenance to keep the warranty valid.

Best time to schedule

March through May, before the first 90-degree day. Pair it with a fall furnace tune-up and your whole system is covered. Call (855) 459-5498 to book in your city.
