Philadelphia and Montgomery County homeowners and small businesses get honest evaluations, quality workmanship, and cooling and heating solutions matched to the property, not the highest-priced equipment on the truck.
Save your time and look elsewhere for reliable hvac services. I drove an hour each way to meet a representative of this company to get a quote for Air Conditioning installation. Their service person did not show up to the appointment despite having made and confirmed the appointment more than a week in advance. The company operators were not able to contact the rep, and no one ever called me back to explain the no-show or apologize, or attempt to make it right. Really disappointing customer service.

Read moreAir Done Right provides ductless mini-split repair, installation, replacement, maintenance, and system diagnostics for homeowners and small businesses throughout Philadelphia and Montgomery County, PA. Our EPA 608-certified technicians service single-zone and multi-zone ductless systems based on the reported problem, property layout, and zone needs.
Air Done Right provides ductless mini split repair in Philadelphia for indoor and outdoor units experiencing no cooling, weak airflow, water leakage, unusual noise, control faults, or a system that will not start or respond to the remote. Our technicians assess the indoor head unit, outdoor condensing unit, refrigerant line set, electrical connections, and condensate drainage to identify the fault rather than assuming which component has failed. Once the diagnosis is complete, we explain what we found and recommend the repair the system actually needs.
Our ductless mini split repair services in Philadelphia, PA include:
An unresolved fault in a ductless system can leave the zone it serves without reliable comfort while continuing to strain the affected components. Schedule ductless mini-split repair with Air Done Right to have a technician identify the cause, explain the findings, and recommend the required repair for your system.
Air Done Right provides ductless mini split installation and replacement in Philadelphia for homes, additions, converted spaces, and small businesses that need new cooling and heating equipment or a replacement for an aging or repeatedly failing system. Ductless mini-splits are a common option for Philadelphia rowhomes and other properties without existing ductwork, where extending traditional ducts to a specific room or floor is impractical. Our EPA 608-certified technicians assess room or zone cooling load, indoor-unit placement, outdoor-unit location, electrical capacity, and line-set routing before recommending a single-zone or multi-zone system.
Our ductless mini split installation and replacement services in Philadelphia, PA include:
Incorrect equipment sizing or poor indoor-unit placement can lead to uneven zone temperatures, short cycling, or a system that runs longer than it should. Talk with Air Done Right about your ductless installation or replacement needs so our technicians can assess the space, explain suitable system options, and determine the required installation scope.
For ductless mini split maintenance and tune-ups in Philadelphia, Air Done Right inspects and services indoor and outdoor equipment to identify conditions that can affect performance over a full cooling and heating season. Filter buildup, coil dust, condensate drainage, and electrical connections on a ductless system need the same regular attention as a central system, and addressing these items before peak season use helps reduce the chance of avoidable breakdowns. Air Done Right’s first annual maintenance visit is included with a qualifying installation.
Our ductless mini split maintenance and tune-up services in Philadelphia, PA include:
Skipped maintenance can let filter buildup, dirty coils, or a slow drain go unnoticed until it affects zone performance. Book a ductless tune-up with Air Done Right to have a technician inspect your system and prepare it for the season ahead.
For urgent ductless mini split problems in Philadelphia, Air Done Right provides emergency repair for situations such as complete loss of cooling or heating during extreme weather, water leakage around an indoor head unit, electrical symptoms like burning odors or repeated breaker trips, or a system that will not respond to controls. We do not add a surcharge for after-hours, weekend, or holiday service, and same-day and weekend availability applies to ductless calls the same as any other HVAC service we provide.
Our emergency ductless mini split repair services in Philadelphia, PA include:
Continuing to run a ductless system with an unresolved electrical, drainage, or refrigerant issue can affect other components and prolong comfort loss in that zone. Contact Air Done Right for emergency ductless mini-split repair so we can diagnose the failure and restore the system as quickly as the situation allows.
By Component
The indoor head unit is the wall-, ceiling-, or floor-mounted component in each zone that delivers conditioned air into the room, and Air Done Right provides indoor head unit repair in Philadelphia for units affected by weak airflow, unusual noise, water dripping, or a display or sensor fault. Our technicians inspect the blower, filter, coil, drain pan, and electrical connections inside the unit to determine why airflow or temperature control has changed. We avoid treating every indoor-unit symptom as a full-system failure before testing the component.
Our indoor head unit repair services in Philadelphia, PA include:
A weak, noisy, or leaking indoor unit can reduce comfort in the specific room or zone it serves even while the rest of the system operates normally. Schedule indoor head unit service with Air Done Right so a technician can identify the affected component and recommend the appropriate repair.
The outdoor condensing unit releases heat during cooling and, on heat-capable systems, reverses that process to draw heat indoors; Air Done Right provides outdoor condensing unit repair in Philadelphia for units affected by restricted airflow, fan or motor problems, electrical faults, debris, or physical damage. Our technicians inspect the outdoor coil, fan, motor, contactor, and electrical connections to diagnose the fault before recommending a repair.
Our outdoor condensing unit repair services in Philadelphia, PA include:
A condenser problem can interfere with heat transfer and reduce the ductless system’s ability to cool or heat as conditions demand. Schedule outdoor unit repair with Air Done Right to identify the affected component and receive a recommendation based on the unit’s condition.
The refrigerant line set connects the indoor head unit to the outdoor condensing unit, and Air Done Right provides refrigerant line set repair and leak diagnosis in Philadelphia for systems showing reduced cooling capacity, ice on the line set, or other refrigerant-related symptoms. Rather than simply adding refrigerant, our EPA 608-certified technicians locate the leak source, inspect line-set connections and insulation, and verify system charge before completing the required repair.
Our refrigerant line-set services in Philadelphia, PA include:
Adding refrigerant without correcting the source of a leak does not resolve the underlying problem and allows the symptom to return. Contact Air Done Right for line-set or refrigerant service so we can locate the fault and explain the appropriate repair.
Ductless systems typically operate through a wall-mounted control, a handheld remote, or both, and Air Done Right provides control and remote repair in Philadelphia for systems with inaccurate temperature response, unresponsive buttons, communication faults between the control and indoor unit, or systems that will not follow programmed settings. Our technicians check control wiring, signal communication, and calibration before recommending a repair or a compatible replacement control.
Our wall-mounted control and remote repair services in Philadelphia, PA include:
A faulty control can leave a zone running when it shouldn’t, ignoring the set temperature, or failing to respond at all. Schedule control service with Air Done Right so a technician can identify the fault and determine whether repair or replacement is appropriate.
Every indoor head unit removes moisture from the air during cooling operation, and Air Done Right provides condensate drain cleaning and repair in Philadelphia for systems with clogged drains, water dripping from the indoor unit, or standing water near the equipment. Our technicians inspect the drain line, drain pan, and drainage path to locate blockages or damage before completing the required service.
Our condensate drain services in Philadelphia, PA include:
A blocked or damaged condensate drain can cause water to drip or pool around the indoor unit and may lead to water damage if left unresolved. Contact Air Done Right for condensate drain service to clear the blockage or complete the required repair.
By Type of System
A single-zone ductless mini-split pairs one indoor head unit with one outdoor condensing unit to cool and, on many models, heat a single room, addition, or converted space, and Air Done Right provides single-zone repair and installation throughout Philadelphia. This configuration fits homeowners who need supplemental comfort in one area, such as a finished attic, sunroom, or garage conversion, without extending existing ductwork or affecting the rest of the property’s HVAC system. Our technicians assess the room’s cooling and heating load, indoor-unit placement, and outdoor-unit location before recommending equipment.
Our single-zone mini-split services in Philadelphia, PA include:
An undersized, oversized, or poorly located single-zone system can leave the room it serves uncomfortable, no matter how well the rest of the equipment functions. Talk with Air Done Right about single-zone ductless service so we can recommend equipment matched to the space.
A multi-zone ductless mini-split connects multiple indoor head units to a shared outdoor condensing unit, allowing several rooms or an entire floor to be controlled independently, and Air Done Right provides multi-zone repair and installation throughout Philadelphia. This configuration suits rowhomes and multi-story properties where different rooms have different comfort needs, or where a whole-home ductless approach replaces the need for central ductwork altogether. Our technicians calculate zone-by-zone loads, plan indoor-unit placement across the property, and size the outdoor unit to support every connected zone.
Our multi-zone mini-split services in Philadelphia, PA include:
A multi-zone system with one underperforming indoor unit can leave a single room uncomfortable while the rest of the zones operate normally, which makes zone-specific diagnosis important. Contact Air Done Right about multi-zone ductless service so we can assess the full system and each connected zone.
By Space
For a single room, addition, converted space, or area that existing ductwork does not reach, Air Done Right provides single-room ductless service throughout Philadelphia. Additions, finished basements, converted garages, and older rowhome rooms without duct access are common candidates for a dedicated ductless zone rather than an extension of a central system. Our technicians assess the specific room’s load, wall and ceiling space for the indoor unit, and outdoor-unit placement before recommending equipment.
Our single-room and addition ductless services in Philadelphia, PA include:
A single room that lacks reliable heating or cooling can remain uncomfortable year-round if it was never part of the original HVAC design. Discuss your addition or single-room cooling needs with Air Done Right so we can recommend the right ductless solution for the space.
For properties that want zoned comfort across the entire home without conventional ductwork, or as a supplement to an existing central system, Air Done Right provides whole-home multi-zone ductless service throughout Philadelphia. A whole-home multi-zone approach lets you control each room or floor independently, which can suit older rowhomes and multi-story properties where uniform central airflow has always been difficult to achieve. Our technicians plan zone counts, indoor-unit locations, and outdoor-unit capacity to support comfort across the full property.
Our whole-home multi-zone ductless services in Philadelphia, PA include:
Inconsistent comfort between floors or rooms is a common reason Philadelphia homeowners consider a whole-home ductless approach instead of continuing to fight an undersized or poorly distributed central system. Talk with Air Done Right about whole-home multi-zone comfort so we can assess your property’s layout and cooling and heating needs.
By Property

Some ductless mini-split symptoms point to a problem that should be assessed promptly, not left for routine maintenance. Watch for the following signs and contact Air Done Right when they appear:
No cooling or heating from an indoor unit while the system is running
Water dripping or pooling around an indoor head unit
Ice visible on the refrigerant line set or indoor coil
The system short cycles, starting and stopping without completing a normal cycle
Burning odors or repeated electrical symptoms during operation
Unusual noise from the indoor or outdoor unit, such as grinding or buzzing
The outdoor condensing unit fails to run or the fan does not turn
Wall-mounted control or remote becomes unresponsive or shows an error
Air Done Right diagnoses and repairs ductless mini-split problems affecting cooling and heating performance, airflow, controls, drainage, and refrigerant circulation throughout Philadelphia. Longer runtimes during peak summer and winter weeks can make existing faults more noticeable, and older Philadelphia properties with a single zone added years ago can develop wear that a newer system has not yet shown.
Philadelphia’s cooling season regularly brings summer highs into the upper 80s, with humidity that keeps the air feeling heavier than the temperature alone suggests, while winters bring average highs in the low 40s and overnight lows in the high 20s, with periodic cold snaps well below that. Because a mini-split’s indoor and outdoor components run for extended periods during both the hottest summer days and the coldest winter stretches, existing wear in the coil, drainage, electrical connections, or refrigerant circuit tends to become noticeable sooner in Philadelphia’s climate than in a milder one.
Air Done Right provides ductless mini-split repair and installation throughout Philadelphia, with a strong focus on Northwest Philadelphia, including Mt. Airy, Chestnut Hill, and Germantown. Our technicians serve homes and small businesses across the city with repair, maintenance, installation, and replacement based on each property's layout and zone needs.
Air Done Right provides ductless mini split repair and installation throughout Northeast Philadelphia. Rowhomes and twin homes in this part of the city commonly need a ductless solution for additions, finished basements, or rooms that were never connected to central ductwork. Our technicians assess the space and existing equipment before recommending repair or installation.
Our technicians provide ductless mini split repair and installation across North Philadelphia. Many North Philadelphia rowhomes were built without central-air ductwork, making single-zone and multi-zone ductless systems a common solution for cooling and heating individual floors or rooms. We check indoor and outdoor equipment, controls, and airflow before recommending service.
At Air Done Right, we provide ductless mini split repair and installation throughout Northwest Philadelphia, including Mt. Airy, Chestnut Hill, and Germantown, an area that represents a strong service focus for our company. Historic properties in this part of the city often have limited mechanical space and additions or converted rooms without ductwork access, which our technicians account for when recommending equipment and planning indoor-unit placement.
We provide ductless mini split repair and installation in West Philadelphia. Older rowhomes and multi-story properties here frequently need supplemental or whole-home zoned comfort where a ductless system is a more practical fit than extending central ductwork. Our technicians assess condition, zone layout, and equipment capacity to determine the appropriate service path.
Ductless mini-split installation starts at around $4,800 per zone. The final installation or replacement cost depends on the number of zones, equipment capacity and efficiency, indoor-unit placement, line-set routing distance, electrical requirements, and selected brand and model.
Air Done Right provides a free, no-obligation estimate for ductless mini-split installation and replacement projects. The estimate reflects the equipment and labor required for the specific property, since every home and installation has different requirements.
Factors influencing ductless mini-split cost include the service type, number of zones, equipment specifications, installation requirements, and project scope. Each factor affects the amount of labor, equipment, materials, or related work required for the project.

The right choice depends on the system's age, the severity of the failure, how often it has needed repairs, and whether the equipment still meets the zone's comfort needs. Air Done Right follows a repair-first approach when practical, diagnosing the system before recommending replacement and explaining both paths so you can decide based on the equipment's condition.
Repair is usually the practical choice when the fault is isolated to a single identifiable component, and the rest of the system is still performing as it should.
Final recommendations always depend on the diagnosis, and repair remains the practical option when the equipment can be restored to reliable operation.
The fault involves a single, identifiable, repairable component
The system otherwise cools or heats the zone properly
Repairs have not become frequent or recurring
Compatible parts are available for the equipment
The overall system remains in serviceable condition
Replacement tends to make more sense once repairs become frequent, a major component fails, or the system's capacity no longer matches what the zone actually needs.
Frequent or recurring repairs on the same unit
A major component failure, such as the compressor or outdoor motor
The system no longer adequately cools or heats the zone
Parts are unavailable or the refrigerant type is obsolete
Cumulative repair costs are approaching the cost of replacement
The zone's needs have changed since the system was installed




Professional ductless mini-split service helps Philadelphia homeowners accurately diagnose problems, complete repairs safely, and avoid replacing equipment when a practical repair can correct the fault. Qualified technicians assess refrigerant, electrical, and control components together, which matters given how tightly integrated a ductless system’s indoor and outdoor components are.
Air Done Right combines licensed HVAC service, EPA 608-certified technical capability, and repair-first recommendations for ductless work across Philadelphia and Montgomery County. Our technicians assess the system and explain the findings before recommending repair or replacement.
Scheduling ductless mini-split service with Air Done Right starts with a straightforward call or online booking that connects you with a technician ready to diagnose the issue and explain your options before any work begins.

Air Done Right is a locally owned, family-operated HVAC company, veteran-owned and women-owned, and led by its husband-and-wife ownership team. Operating in the Philadelphia and Montgomery County area since 2013, the company holds PA HIC License #PA093007 and staffs EPA 608-certified technicians who service central air conditioning, heat pumps, and ductless mini-split systems. Air Done Right's focus on diagnosing before recommending, providing transparent pricing, and backing installations with a 5-year labor warranty applies to ductless work the same as any other HVAC service the company provides.
Ductless mini-split service is professional work performed to inspect, diagnose, repair, maintain, install, or replace a ductless heating and cooling system, depending on the need. Maintenance focuses on preventive care, repair addresses an identified fault, and installation places or replaces the indoor and outdoor equipment.
The 3-minute rule generally refers to waiting a short time before restarting a system after it shuts off, giving internal pressures time to stabilize and protecting the compressor from an immediate restart. Homeowners should follow the manufacturer's operating instructions for their specific ductless system rather than treating three minutes as a universal rule.
A well-maintained ductless mini-split typically lasts 15 to 20 years, generally comparable to or slightly longer than a central AC system, though actual service life depends on installation quality, maintenance history, usage patterns, and repair history. Philadelphia's hot summers and cold winters mean both cooling and heating runtime affect equipment wear.
Air Done Right installs ductless equipment based on the property's zoning needs, cooling and heating load, and installation conditions.
Schedule professional ductless maintenance at least once a year, ideally before your heaviest season of use. Because a ductless system in Philadelphia runs through both a humid cooling season and a cold heating season, regular maintenance helps catch filter buildup, coil dirt, and drainage issues before they affect performance in either season.
In most cases, yes. New ductless mini-split installations generally require a Mechanical Permit through the City of Philadelphia's Department of Licenses and Inspections, and installations that add new electrical circuits or outdoor disconnects may also require an Electrical Permit. Many installations in one- or two-family homes may qualify for the city's EZ permit process. Air Done Right handles applicable permitting as part of a scheduled installation.
Yes. Ductless mini-splits are specifically designed for properties without existing ductwork, including many Philadelphia rowhomes, additions, and converted spaces. Air Done Right assesses available wall and ceiling space, electrical capacity, and line-set routing before recommending a single-zone or multi-zone system for a property that was never built with central ductwork.
Many straightforward repairs can be completed during the initial service visit, while repairs requiring ordered parts may take longer. Air Done Right identifies the problem first and explains whether the repair can be completed the same day or requires a follow-up visit.
Installation time depends on the number of zones, line-set routing complexity, required electrical work, and site access. Air Done Right evaluates the project scope during the estimate and provides an installation schedule before work begins.
The correct system size depends on the room or property's cooling and heating load, not square footage alone. Factors such as insulation, windows, ceiling height, occupancy, and the number of zones influence the required capacity, and a proper load calculation should guide equipment selection rather than a simple size-per-square-foot rule.
An older ductless system can only be recharged with a refrigerant compatible with that specific equipment, and current refrigerants are not automatically interchangeable with older ones. A technician must identify the system's refrigerant type, equipment compatibility, and any active leak before determining whether refrigerant service is appropriate. Repeatedly adding refrigerant without diagnosing an active leak does not address the source of refrigerant loss.
Air Done Right can diagnose older ductless equipment to determine its condition and available service options, but repair feasibility depends on the brand, model, refrigerant type, failed component, and availability of compatible replacement parts. After inspecting the equipment, our technicians explain whether repair remains practical or whether to consider replacement.
Turn off the system and avoid running it while the indoor coil or line set remains frozen, or while water is actively leaking around the indoor unit. Restricted airflow, a dirty filter or coil, drainage problems, or refrigerant-related conditions can contribute to either symptom, and a technician should diagnose the cause if the problem persists or returns after the system is turned off.
Longer runtimes can occur during Philadelphia's hottest and most humid periods because the system is working to remove heat and moisture, but continuous operation combined with poor cooling can indicate a problem. Restricted airflow, a dirty coil, control faults, refrigerant conditions, or an undersized system for the zone can contribute to excessive runtime and should be assessed if the space cannot reach the intended temperature.
