Wondering how often should HVAC be serviced? Learn a practical Westchester maintenance schedule that helps protect comfort, efficiency, and safety year-round.

Westchester summers spike fast. The first 85-degree day every year exposes the central A/C, ductless system, or heat pump that wasn't ready. Compressors fail, refrigerant runs low, condensate drains clog, and capacitors give out, all in the same week the rest of Westchester is calling for service. The customers who book a pre-season A/C tune-up in late April and early May are the ones who get through July without an emergency call. Plitnick has serviced cooling systems across Dobbs Ferry, Hastings-on-Hudson, Irvington, Tarrytown, Yonkers, White Plains, Ardsley, and the surrounding river towns since 1977. Below is the seasonal A/C tune-up checklist our crew runs every spring, plus the issues we see most often in pre-war and modern Westchester homes. What a Plitnick A/C tune-up actually covers A real A/C tune-up is not just a filter swap. Our crew runs through fifteen-plus checks on every system: refrigerant pressure check (low charge means the compressor works harder and fails earlier), coil cleaning indoor and outdoor (dirty coils kill efficiency by 15 to 30 percent), capacitor and contactor inspection (these fail more often than any other A/C component), condensate drain flush (a clogged drain can flood a basement or trip a safety switch in the middle of a heat wave), blower motor amp draw (a motor pulling high amps is days from failing), thermostat calibration (the system is only as smart as the thermostat telling it what to do), electrical connection tightening, filter replacement, and ductless mini-split filter and indoor unit cleaning where applicable. We document each check, photograph anything that needs attention, and walk you through what we found before quoting any repair work. Westchester-specific A/C issues we see every spring Westchester's housing mix means we see a different distribution of issues than a flat-suburb HVAC company in another state. Pre-war homes in Hastings, Irvington, Dobbs Ferry, and Tarrytown river-front districts often have high-velocity Unico systems or ductless retrofits because they were never built for ductwork, and these need different maintenance than a standard central system. Mid-century homes in Yonkers, White Plains, and Ardsley often have original 30-plus-year-old air handlers running on R22 refrigerant; R22 was phased out in 2020 and is no longer manufactured, so if your system uses R22, every leak repair costs more than the last one. Newer homes and renovations have R410A systems, the post-R22 standard, that are now being phased down in favor of R454B for systems installed in 2025 and beyond. Mitsubishi Electric ductless systems, which we install as a Diamond Contractor, need annual indoor-unit cleaning to keep the head from freezing up in humid Westchester summers. When to skip the tune-up and just replace the system Sometimes a tune-up is throwing good money after bad. Replace, do not repair, when the system is over 12 years old and uses R22 refrigerant, the compressor is failing (compressor replacement is half the cost of a new system), your last three summers each had a $300-plus repair, or you are upgrading the home anyway and want to qualify for NY State Clean Heat rebates on a heat pump. We will tell you straight up if a tune-up is the wrong call. We do not push replacements that you do not need. What homeowners can do themselves Replace the air filter every 30 to 60 days during heavy use. Clear leaves, branches, and grass clippings from around the outdoor condenser unit; give it 24 inches of clearance on all sides. Wipe down the outdoor coils gently with a garden hose, top to bottom, but do not pressure-wash because you will bend the fins. Test that the condensate drain is flowing by pouring a half cup of bleach into the access port if your unit has one. What to leave to a licensed pro: anything involving refrigerant, electrical components, or the compressor. When to book your tune-up The best time to book a Westchester A/C tune-up is late April through mid-May. Book before the first 80-degree day, because after that every HVAC company in Westchester is buried in emergency calls; before Memorial Day weekend, because we get fully booked; and before your annual filter is due. Plitnick's annual A/C service agreement covers the spring tune-up plus priority emergency response throughout the summer. Service-agreement customers get scheduled before non-agreement customers when emergencies hit during heat waves.

Your Air Conditioner Stops Working on the Hottest Day of the Summer. Sound Familiar? For homeowners in Dobbs Ferry, Yonkers, White Plains, Tarrytown, and throughout Westchester County, a broken AC is not just uncomfortable. It can be a real problem for families, older residents, and anyone trying to work from home. The term “AC repair” gets used a lot, but what does it actually mean? What does the process involve, what are the warning signs that your system needs attention, and when should you call a professional? This guide breaks it all down so you can make informed decisions about your home’s cooling system and know exactly what to expect when you call Plitnick Plumbing and Heating. What Is AC Repair, Exactly? AC repair refers to the diagnosis and correction of problems within an air conditioning system. This can involve anything from replacing a single faulty component, like a capacitor or contactor, to repairing refrigerant leaks, fixing electrical failures, or restoring airflow through a clogged system. AC repair is different from AC maintenance. Maintenance is scheduled, preventive work done before problems occur. Repair is reactive work done in response to a system that is already underperforming or has stopped working entirely. At Plitnick Plumbing and Heating, we handle AC repair for a range of systems across Westchester County, including: Central air conditioning systems Ductless mini-split systems Heat pump systems used for cooling Common Types of AC Repairs in Westchester County Homes Not all AC repairs are created equal. Some are minor fixes that take an hour. Others require parts replacement or more involved diagnostic work. Refrigerant Leak Detection and Repair Refrigerant is the substance that makes cooling possible. When your system develops a leak, it cannot absorb enough heat to cool your home effectively. You may notice your home feels warm even when the AC is running constantly. Refrigerant leaks require a licensed technician to locate the leak, repair it, and recharge the system to manufacturer specifications. Capacitor and Contactor Replacement Capacitors give your AC’s motors the electrical boost they need to start and keep running. When a capacitor fails, the compressor or fan motor may not start, leaving your system blowing warm air or not turning on at all. This is one of the most common AC repairs in the region and is typically straightforward for a trained technician. Condensate Drain Line Cleaning and Repair Your AC removes humidity from the air, and that moisture needs somewhere to go. The condensate drain line carries it away. When that line becomes clogged with algae, mold, or debris, water can back up into the system and cause damage, trigger shutoffs, or lead to water leaks inside your home. Electrical Component and Wiring Repairs Faulty wiring, blown fuses, or tripped breakers can all prevent your air conditioner from running properly. Electrical issues inside HVAC equipment should only be addressed by a licensed professional. Attempting to diagnose or fix electrical problems on your own is both dangerous and potentially damaging to the system. Compressor Issues The compressor is the heart of your air conditioning system. It circulates refrigerant and drives the cooling cycle. Compressor problems are among the more serious AC repairs and can result from low refrigerant levels, electrical failures, or simple wear and tear on an aging system. In some cases, a failing compressor may signal that a full system replacement is more cost-effective than a repair. Ductless Mini-Split Repairs Ductless systems have become increasingly popular in Westchester County homes, especially in older houses that do not have existing ductwork. Common ductless repair issues include refrigerant leaks, drainage problems, remote control malfunctions, and indoor unit fan failures. Plitnick handles ductless repair and maintenance for systems throughout the area. Warning Signs Your AC Needs Repair in Dobbs Ferry, NY Catching a problem early almost always costs less than waiting until the system fails completely. These are the warning signs Westchester County homeowners should not ignore: 1. Your AC Is Blowing Warm Air If conditioned air coming from your vents feels warm or room temperature, your system has lost its ability to cool. This can point to a refrigerant issue, a compressor problem, or a failed component. 2. Airflow Is Weak or Inconsistent Poor airflow through your vents could indicate a clogged filter, a failing blower motor, or leaky ductwork. Rooms that are harder to cool than others often point to airflow distribution issues. 3. You Hear Unusual Noises Banging, hissing, grinding, or squealing coming from your AC unit are not normal operating sounds. Each type of noise points to a different potential issue and should be evaluated by a technician as soon as possible. 4. You Notice Moisture or Water Near the Unit Leaking water around an indoor air handler or pooling near the outdoor condenser unit is a sign something is wrong. Refrigerant leaks can also cause ice to build up on the coils, which then melts and creates water pooling. 5. Your Energy Bills Are Climbing A system that is struggling to cool your home will run longer and work harder, drawing more electricity in the process. If your summer utility bills are noticeably higher without a change in usage habits, your AC efficiency may have dropped due to an underlying repair issue. 6. You Smell Something Musty or Burning A musty odor can indicate mold growth inside the system or ductwork. A burning smell may point to an electrical issue. Neither should be ignored. AC Repair vs. AC Replacement: How to Know Which One You Need One of the most common questions homeowners ask is whether they should repair a system or replace it entirely. There is no single answer that fits every situation, but a few guidelines can help you think it through. Repair is typically the right call when: The system is less than 10 years old The repair cost is less than half the cost of a new system The unit has been well maintained Replacement tends to make more financial sense when: The system is 15 or more years old Repairs are becoming frequent The system uses R-22 refrigerant, which is now phased out and expensive to source Energy bills have climbed consistently despite regular maintenance When a Plitnick technician comes out to diagnose your system, they will give you an honest assessment of both options so you can make the decision that makes the most sense for your home and your budget. What to Expect During an AC Repair Service Call If you have never had a professional AC repair service before, knowing what happens during a service call can help remove any uncertainty. Diagnosis The technician will evaluate your system, check refrigerant levels, test electrical components, inspect the coils and drain line, and identify the root cause of the problem. Explanation Before any work begins, you will receive a clear explanation of what was found and what repair is recommended. No surprise charges. Repair The technician completes the approved repair using quality parts and proven methods. Testing After the repair, the system is tested to verify it is operating correctly before the technician leaves your home.
