Air Conditioning Maintenance
Air Conditioning Maintenance in Berks County, Pennsylvania by Penn Mechanical Company
Cool should be easy: set a temperature and every room settles in. When it isn’t, the clues stack up longer run times, warm air at the vents, musty start-up odors, ice on the copper line, or water near the air handler. Add uneven rooms or a bill that doesn’t match the weather, and you’re looking at more than summer being summer. Airflow, refrigerant, and drainage are not in balance.
Air Conditioning Services Company fixes the cause not just the symptom with a maintenance visit that cleans, measures, and dials in the parts of your system that deliver comfort.
What Our A/C Maintenance Includes (the functions that matter)
- Coils & Heat Transfer
We wash the outdoor condenser coil and clean the indoor evaporator (access permitting) so heat can move freely. Clean coils = quicker cool-downs and better humidity removal. - Airflow & Duct Performance
We set blower speeds to target airflow, check static pressure, verify return/supply sizing, and make practical recommendations if ducts are choking the system. - Refrigerant Performance (No Guesswork)
We evaluate charge by superheat/subcooling against the manufacturer’s targets—never by feel—to protect the compressor and restore capacity. - Electrical & Safety
We test capacitors, contactors, relays, and tighten connections. We confirm the system starts and runs within safe amp draw and voltage ranges. - Condensate & Moisture Control
We clear and treat the drain line, verify trap and slope, and test the float safety switch so water stays out of ceilings and closets. - Controls & Thermostat
We verify mode changes, schedules, and staging—making sure your thermostat isn’t working against you.
You’ll get a short report with key readings—temp split, static pressure, superheat/subcooling, amp draws so you know the system isn’t just running; it’s in spec.
Signs You’re Due for Maintenance (from general to specific)
- System runs and runs yet struggles to reach the setpoint
- Supply air feels lukewarm, or humidity stays high indoors
- Musty or dirty sock odor when the A/C starts
- Ice on the large copper line or sweating ducts
- Water in or around the furnace/air handler
- New noises—buzzing, chattering, or fan squeal
- A utility bill spike without a matching heatwave
Two or more of these? Book a tune-up before the next hot spell.
Benefits You’ll Notice After a Proper Tune-Up
- Faster pull-down on hot afternoons
- Quieter operation from correctly set fans and clean coils
- Drier, more comfortable rooms thanks to restored dehumidification
- Even temperatures upstairs and down when airflow is right
- Lower risk of breakdowns and leaks because drains and electrical components are in order
Ducted, Ductless, and Zoned: What We Tweak Differently
Central (Ducted) A/C
We focus on coil cleanliness, blower setup, return airflow, and sealing filter cabinets so the coil stays clean and the blower isn’t starved.
Ductless / Mini-Split
We wash indoor filters and coils, confirm drain slope or quiet pump operation, verify fan settings, and check charge. Clean heads = quiet, efficient cooling.
Zoned Systems
We test damper operation and confirm the blower profile protects the equipment with smaller zone calls no wind tunnel or coil icing.
Simple Seasonal Plan
- Spring (pre-cool): full tune-up—coils, airflow, refrigerant, drains, and controls
- Mid-season touch-up (optional): outdoor coil rinse if your home sees heavy pollen/cottonwood
- After renovations: schedule a check—construction dust loads, filters and coils fast
Homeowner Habits Between Visits (small tasks, big results)
- Replace or clean filters on schedule (often every 1–3 months)
- Keep 2–3 ft of clearance around the outdoor unit; trim shrubs and blow out grass clippings
- Pour a cup of approved cleaner or warm water through the condensate access (if provided) to discourage algae
- Don’t rapid-fire heat/cool mode changes; give the system a few minutes to settle
- If you see ice or standing water, shut the system off and call—don’t chip ice or bypass a float switch
Frequently Asked Questions
Yes—keeping coils clean, charge correct, and drains clear prevents efficiency loss and mid-season failures.
Not without finding the cause. Adding refrigerant without leak detection is a short-term patch that risks the compressor.
Sometimes. If airflow or duct returns are the bottleneck, we’ll show you simple upgrades (added returns, balancing) that make a big difference.
