Coastal has specialized in automotive air conditioning for more than three decades. We diagnose the actual fault, find the leak other shops miss, and repair it properly — on every make and model, R-134a and R-1234yf.
That one sentence has at least six different causes, and the fix for one is nothing like the fix for another. That's the part that costs people money — a shop that treats every warm-air complaint as a refrigerant top-off will have you back in six weeks with the same warm vents and a lighter wallet. (Curious how the system works? Walk the refrigerant loop in 3D on our services page →)
By far the most common cause. Leaks show up at O-rings, hose crimps, the condenser (which sits up front and takes road debris), the evaporator inside the dash, or a leaking compressor shaft seal.
Usually preceded by weeks of weakening cold, a noise on engagement, or a clutch that stops engaging altogether.
A clogged expansion valve or orifice tube starves the evaporator and kills cooling even when the system holds a full charge.
The A/C is working fine — the door that mixes hot and cold air is stuck on the heat side. Common on late-model vehicles and frequently misdiagnosed as an A/C fault.
Cold at highway speed, warm in traffic. That's an airflow symptom, not a refrigerant symptom, and adding refrigerant won't touch it.
The cheapest one on the list. Airflow drops and the vents feel weak while the refrigerant side is perfectly healthy.
The one thing we won't do is add refrigerant to a leaking system and call it a repair. A sealed system isn't supposed to consume refrigerant.
Vent temperature at the center duct and pressure readings on both the high and low side with the system under load. Those numbers alone rule out most of the list above.
Electronic leak detection and UV dye where needed, plus a vacuum hold test to confirm the system is actually sealed before any refrigerant goes into it.
You get the diagnosis, the price, and the timeline before we start. If part of it can safely wait, we'll tell you that too.
We recover the existing refrigerant rather than venting it, replace the failed component, and replace the receiver/drier or accumulator any time the system has been opened to atmosphere. That part absorbs moisture, and reusing a saturated one is how a brand-new compressor gets killed a second time.
Then we pull a deep vacuum to boil off any moisture left in the system and confirm it holds — which doubles as the final leak check. We weigh in the exact factory refrigerant charge, measured rather than guessed from gauge pressure, with the correct type and amount of compressor oil. Last step is a re-test of vent temperature and pressures before the vehicle leaves.
How long it takes. Diagnosis runs about an hour. A straightforward evacuate-and-recharge is usually same day. Component replacement depends entirely on where the part lives — a condenser or compressor is generally accessible and often same or next day, while an evaporator sits inside the dash and takes considerably longer because the dash has to come apart to reach it.
R-134a vs. R-1234yf. Vehicles built roughly before 2015 use R-134a. Most newer vehicles use R-1234yf, which costs significantly more per pound and needs separate equipment to service correctly. It's the single biggest reason two A/C recharges on two different cars have very different prices. We're equipped for both, and we'll tell you which one your vehicle takes when you call.
This shop opened on Bustleton Pike as a specialist radiator and air-conditioning shop in the early '90s. It's the system we've worked on longest and the reason customers drive here from Southampton, Langhorne, Richboro, and Northeast Philadelphia.
Parts and labor warranty on most work. Our diagnostic fee is $110, and you get the findings and the price before any repair begins. Financing is available through 1stMile if a larger repair needs to be spread out.
Domestic and import, cars, light trucks, and work vehicles. We're also an official PennDOT inspection station — if something else turns up while we're in there, we can handle it in the same visit instead of sending you elsewhere.
It's whether your driver can work all day. We handle bulk recharges, seasonal A/C inspections, and preventive service scheduled around your routes, so vehicles come in on your slow day instead of failing on your busy one. Commercial accounts get a dedicated fleet labor rate — call the shop and ask for fleet scheduling.
If your question isn't here, give us a call — we're happy to talk it through.
