Where it usually goes wrong
Air conditioning is the service people put off longest and regret fastest. It almost always fails gradually: cold at first, then cold only on the highway, then warm. By the time it blows warm the leak that caused it has usually been there a season.
We do not sell a recharge as a fix. If a system is low on refrigerant, something let it out, and putting more in without finding where is a repair that lasts until the weather turns. Every AC job here starts with pressures on the gauges and a leak test, and you get the finding before anything is charged.
Heat is the other half of the same system, and it fails in winter for different reasons: a thermostat stuck open, low coolant, or a blend door that stopped moving. We check the cooling system before touching the dash, because a car that never warms up is usually not an HVAC fault at all.
Start here
Most AC and heat complaints fall into one of these. The middle column is the likely cause, not a promise; the right column is what we actually do about it.
How an AC service runs
We run the system and measure vent temperature, because warm air and weak air are different faults with different fixes.
High and low side pressures on the gauges tell us whether the charge is low, whether the compressor is pumping, and whether there is a restriction.
If the charge is low, something let it out. Dye or an electronic detector finds where, and we show you.
You get the fault, the fix and the figure before anything is opened up or recharged.
The system is pulled into vacuum to boil off moisture, then charged by weight to the manufacturer's specification, not by eye.
Vent temperature and pressures are checked again with the car running, so you leave knowing it works.
Looking after it
Three things worth knowing
Heat and defrost
A heater that never gets hot is usually not a heater problem. The most common cause is a thermostat stuck open, which keeps the engine below operating temperature so there is no heat to give. Low coolant does the same thing, and so does air trapped in the heater core after a cooling-system repair.
Heat on one side but not the other, on a car with dual-zone climate, is almost always a blend door actuator. They are small motors behind the dash and they announce themselves with a clicking sound. We command them with a scan tool to confirm which one has failed before anything comes apart.
Defrost matters more than comfort. A windshield that will not clear is a visibility problem, and on a wet January morning in New Jersey that is a safety issue rather than an inconvenience. If your defrost has gone weak, book it before the first frost rather than after.
Both halves share the blower motor, the cabin filter and the duct work, which is why a weak-airflow complaint in July and a poor-defrost complaint in January often turn out to be the same filter.
What drivers say
I needed a simple brake service, but I did not expect these guys work in the 21st century environment. They communicated with me via detailed text messages, and kept me involved in all decision-making.
Came here for brake pads and rotors. Got a good price, and they did a good job. They did a road test also.
Great service, they got me in same day for full brakes front and back. Definitely recommend.
Car AC repair near me
If you searched for car AC repair near me, AC recharge near you, or auto air conditioning repair, that is this visit. We are in Clifton, Franklin, Hawthorne and Newton, and the leak test comes before the recharge at all four.
AC faults overlap with other systems. An engine that runs warm with the AC on is a cooling system question. A compressor clutch that will not engage can be electrical rather than mechanical. We find out which before quoting.
Answers to some of the questions KRP Automotive customers ask most. Still not sure? Give us a call, we’re happy to help.
Most often the refrigerant charge is low, which means the system has a leak. It can also be a compressor clutch that is not engaging, or a cooling fan that is not running so the condenser cannot shed heat. We read the pressures and leak-test before adding anything.
It depends which refrigerant your car takes. Vehicles built since roughly 2021 use R-1234yf, which costs considerably more than the older R-134a, and the amount a system holds varies. We tell you the figure after the leak test, because a recharge without finding the leak is money spent twice.
No. Refrigerant is not consumed. A sealed system holds its charge for years, so if yours needs topping up annually it has a leak that is worth finding.
That pattern points at airflow across the condenser rather than the refrigerant. At speed the air does the work; at idle the cooling fan has to, and if the fan is not running or the condenser is blocked you lose cooling at the lights.
Usually a thermostat stuck open or low coolant, both of which keep the engine below operating temperature so there is no heat to send to the cabin. That is a cooling-system fault rather than an HVAC one, and we check it first.
Moisture sitting on the evaporator, which is common on cars used for short trips. We treat the evaporator and replace the cabin air filter rather than covering it with a scent.
Yes. They are not interchangeable and they need separate equipment, which is why some shops only handle one. We work on both.
An AC tune up is the cheap version of this job, and our AC specialist will say so when that is genuinely all the system needs. Where it is not, we find the leak rather than topping it up and sending you away. Emergency AC repair in a heatwave is treated as urgent rather than routine, same day wherever we can.
Most repairs at KRP Automotive are guaranteed for as long as you own your vehicle. If you pay for a repair at our shop, you shouldn’t have to pay for it again, that’s our promise at all four open New Jersey locations.
