Same-day diagnostics. Upfront pricing. EPA 608 certified technicians serving all of Delaware.
(302) 492-1333It is 11 PM in July. Your AC stopped blowing cold air two hours ago. The thermostat reads 87 and climbing. Your kids cannot sleep. The dog is panting on the tile floor. You called two companies already. Both sent you to voicemail.
Air Doctorx picks up the phone. We dispatch EPA 608 certified technicians from our Hartly shop, and we cover every county in Delaware. We find the problem, tell you the price before we touch anything, and get your house cool again. Most calls, same day. We handle ac repair in Delaware for every major brand. If your system needs routine AC maintenance instead of a repair, we will tell you that too.
A failed capacitor or dead compressor stops the cooling cycle. The blower pushes air but nothing chills it. Capacitor replacement runs $150 to $350. Compressor work starts at $1,200. The longer you wait, the more likely the compressor overheats and fails completely.
Short cycling points to a bad contactor, dirty filter choking airflow, or low refrigerant. A contactor swap costs $150 to $300. A clogged filter is free to replace yourself. But if the root cause is low refrigerant, you have a leak that gets worse every cycle.
A dirty filter restricts airflow across the evaporator coil and freezes condensation in place. Left alone, ice blocks the entire coil and forces a shutdown. Filter replacement is step one. If the coil is damaged, replacement runs $800 to $1,500.
A clogged condensate drain or cracked drain pan sends water across your floor. Ignore it for a weekend and mold starts growing in your walls. Condensate line clearing is a quick fix. Drain pan replacement is under $200.
Low refrigerant from a slow leak is the most common cause. R-410A recharge: $200 to $400. R-22 recharge on older systems: $300 to $600 and climbing because R-22 is no longer manufactured. If your system runs R-22, every recharge costs more than the last.
Musty or moldy smell means biological growth inside the air handler or ductwork. The evaporator coil stays wet during operation and breeds mold in humid Delaware summers. Coil cleaning and drain treatment solve most cases. Persistent odor may require duct cleaning.
Indoor air handler plus outdoor condenser. The most common AC setup in Delaware homes. We service both components and the refrigerant lines connecting them.
All-in-one systems mounted outside or on the roof. Common in mobile homes and older commercial properties. Every component sits in one cabinet, which means one service call covers everything.
Wall-mounted indoor heads connected to an outdoor compressor. Popular in older Delaware homes without ductwork and as zone additions. Mitsubishi, Fujitsu, LG, and Daikin systems serviced.
Your heat pump cools your home in summer using the same refrigerant cycle as a standard AC. When cooling fails, the problem often sits in the reversing valve or refrigerant charge. See our heat pump repair page for heating-mode issues.
R-22 (Freon) was phased out in 2020. Remaining supply is scarce and expensive: $300 to $600 per recharge. R-410A systems use readily available refrigerant at $200 to $400 per recharge. If your system still runs R-22, we help you weigh recharge vs. replacement math.
We waive the diagnostic fee when you approve the repair. You only pay for the fix, not the visit.

Our tech checks refrigerant pressure, electrical connections, airflow, and thermostat calibration. You know exactly what broke before we talk about fixing it.
You see the number in writing before we pick up a tool. No surprise charges. No hourly billing. Most AC repairs wrap up in one visit.
We run the system, check temperatures at every vent, and clean up our workspace. We do not leave until cold air is blowing. If you also need heating repair, we assess that system during the same visit.
Our diagnostic fee is $79 to $99 and rolls into the repair cost if you move forward. Here is what common AC repairs cost in Delaware:
Capacitor replacement: $150 to $350. The most common AC repair. A failed capacitor stops the compressor or fan motor from starting.
R-410A refrigerant recharge: $200 to $400. Price depends on how much refrigerant your system lost and whether we need to locate and seal the leak.
R-22 refrigerant recharge: $300 to $600. R-22 is no longer manufactured. Every year the remaining supply shrinks and the price climbs. Systems still running R-22 are candidates for replacement.
Fan motor replacement: $300 to $700. Indoor blower motors and outdoor condenser fan motors both fall in this range. A grinding or squealing noise usually means the motor is failing.
Evaporator coil replacement: $800 to $1,500. A corroded or leaking evaporator coil cannot be patched. Replacement includes recovering refrigerant, swapping the coil, and recharging the system.
Compressor replacement: $1,200 to $2,800. The most expensive AC repair. If your system is over 10 years old and needs a compressor, AC installation often makes more financial sense.
