Not sure if your air conditioner needs professional service? Look for these common warning signs:
Weak or No Airflow - If your AC is running but not blowing cold air, there could be a compressor, ductwork, or airflow issue.
Unusual Noises - Banging, grinding, or squealing sounds may indicate loose components or a failing motor.
Frequent Cycling - If your AC turns on and off frequently, it could be a sign of a faulty thermostat, clogged filter, or refrigerant leak.
Water Leaks or Ice Build-Up - Ice on the coils or leaking water near your unit could indicate blocked drains or refrigerant issues.
Higher Energy Bills - A sudden spike in electricity costs may mean your AC is working harder than necessary due to inefficiency.
If you're experiencing any of these common AC issues, don't wait - call 717 Mechanical LLC at (717) 468-9567 for expert air conditioning repair in Marietta, PA today! Delaying repairs can lead to more expensive damage and higher energy bills.
Not sure if it's worth repairing? If your system is over 10-15 years old or the repair cost exceeds 50% of replacement value, it may be time for a new AC installation. We provide honest assessments every time. For a full breakdown of how to make that call, read our guide on when to replace your air conditioner. We provide air conditioning repair across Lancaster County, including Lancaster, Manheim, Millersville, and Ephrata.
At 717 Mechanical LLC, we follow a step-by-step approach to quickly diagnose and repair AC problems, ensuring long-term performance.
Most central air conditioning breakdowns in Lancaster County homes trace back to a short list of causes. Here is what the symptom usually means and how we fix it:
Symptom: the system runs constantly but the air from the vents is barely cool. Cause: a pinhole leak in a coil or a loose fitting has let the charge drop. We find and repair the leak, then recharge to the manufacturer's specification instead of simply topping it off.
Symptom: the outdoor unit hums but the fan will not spin, or the AC clicks on and shuts right back off. Cause: a weak start or run capacitor, common after a few humid Pennsylvania summers. It is one of our fastest repairs, and catching it early protects the compressor.
Symptom: ice on the indoor coil or refrigerant lines and weak airflow at the vents. Cause: restricted airflow from a clogged filter, blocked returns, or a failing blower, or low refrigerant. We thaw the coil, fix the airflow problem, and check the charge so it does not freeze again.
Symptom: the outdoor unit is loud, trips the breaker, or will not start. Cause: a hard-starting or failing compressor, often the result of an ignored capacitor or refrigerant problem. We test it before recommending anything, because on an older system this is where the repair-or-replace conversation starts.
Symptom: squealing or grinding from the outdoor unit, or an indoor blower that runs slowly or not at all. Cause: worn bearings or a burned-out condenser fan or blower motor. We replace the motor and confirm airflow is back where it should be.
Symptom: water pooling around the indoor unit, a musty smell, or an AC that shuts off on its float switch. Cause: algae or sediment has blocked the drain line, which happens fast in our humid summers. We clear the line, clean the drain pan, and confirm the safety switch works.
Not sure which of these you are looking at? Our guide to why your AC isn't blowing cold air walks through the checks you can do safely before you call.

Get a QuoteNot every breakdown is worth fixing. A common industry rule of thumb is the $5,000 rule: multiply the age of your air conditioner in years by the repair estimate. Under 5,000, repair is usually the sensible choice. Over 5,000, or if the system is past 12 to 15 years and facing a compressor or coil replacement, the money is better spent on AC installation in Marietta, PA. We walk through the numbers with you on site and give you a straight answer either way.
