Cooling Services
Cool, Dry and Comfortable All Summer
When a New Jersey heat wave hits, a failed air conditioner stops being an inconvenience and starts being a health issue. We prioritize no-cooling calls, and our technicians carry the parts that fail most often so many repairs are finished on the first visit.
Planning ahead instead? A properly sized, professionally installed high-SEER system will cut your summer electric bill and dehumidify far better than the oversized unit it replaces. Estimates are free.
AC Repair
Air Conditioning Repair
We find the actual fault instead of throwing parts at it. Capacitors, contactors, condenser fan motors, refrigerant leaks, frozen evaporator coils, clogged condensate lines, failed thermostats. We diagnose it, price it, and only then fix it.
One tip that saves systems: if your AC is running but not cooling, shut it off. Running a unit that is low on refrigerant or starved for airflow is how a $300 repair becomes a $3,000 compressor.
- System runs but will not cool
- Warm air from the vents
- Ice on the coil or line set
- Water leaking around the air handler
- Loud, grinding or buzzing outdoor unit
- AC trips the breaker
- Short cycling
- Musty smell when it runs
AC Installation
New AC Installation & Replacement
Half of an air conditioner's real-world performance comes from the install. We start with a load calculation, not a rule of thumb, and then check your ductwork, static pressure and returns before recommending equipment. Oversized systems cool fast, shut off, and leave your house cold and clammy; right-sized systems run longer, quieter and drier.
We primarily install Lennox air conditioners and heat pumps, and every install includes removal of the old equipment, a full commissioning check, and a walkthrough of your new thermostat.
- Free in-home estimate
- Proper load calculation & sizing
- High-SEER2 ENERGY STAR® systems
- Matched indoor/outdoor equipment
- Financing on approved credit
- Smart thermostat setup included
- Old system removed & disposed
- Full system commissioning
AC Maintenance
Spring Tune-Ups That Prevent August Breakdowns
Every spring a Mighty Ducts service mechanic performs a full cooling inspection: temperature split across the coil, operating pressures, compressor and motor amp draws, capacitor test, electrical connections, condensate drain and overflow safeties, coil cleanliness, and a new filter. We clear out the debris (and the nests) that build up in the condenser over winter.
It is the cheapest thing you can do for an air conditioner, and it keeps your warranty intact. Bundle it with the fall heating visit through our maintenance agreement.
Filter Replacement
AC & Furnace Filter Replacement
A clogged filter is the number one cause of avoidable HVAC service calls. It restricts airflow, freezes evaporator coils in summer, trips high-limit switches in winter, and quietly raises your energy bill the whole time.
We will identify the right filter size and MERV rating for your system: high enough to actually clean your air, but not so high that it strangles the blower. We can also supply replacements so you are never hunting for the odd size at the hardware store.
Prefer to handle it yourself? Order the right filter from our online store and have it shipped to your door.
- Correct size & MERV rating for your system
- 1-inch and 4/5-inch media filters
- Filter supply for maintenance customers
- Whole-home filtration upgrades

Cooling Questions We Hear a Lot
Most often it is a dirty filter or coil choking airflow, low refrigerant from a leak, or a failed capacitor on the outdoor unit. Turn the system off before it freezes the coil solid, replace the filter, and give us a call. Running a starved system can turn a small repair into a compressor replacement.
It is not strictly required, but it is strongly advised. Today's high-efficiency systems earn their energy ratings as a matched set. Mismatched equipment will not deliver the rated efficiency and often voids the warranty. Replacing both in one visit also costs less in labor than two separate jobs later.
High-efficiency air conditioners use a compressor with both a high and a low speed. Running mostly on low means more even cooling, much better dehumidification, quieter operation, and fewer hard starts, which saves energy and reduces wear on the system.
A standard 1-inch filter every 1–3 months; 4- and 5-inch media filters typically once or twice a year. Pets, allergies or construction dust mean the shorter end of that range. A clogged filter is the single most common cause of the service calls we get.
In New Jersey the sweet spot for most homes is a 15–18 SEER2 system. Going higher can pay off if you run AC heavily or have high electric rates, but only if the ductwork and installation are right. A sloppily installed 20 SEER unit will underperform a properly installed 16.
