A/C checks, leak tests, recharges and compressors — measured with gauges and dye, not guessed, so the cold air you paid for in May is still there in August.
A dark car in a Tucson lot reaches 118° inside by early afternoon. This is where every A/C system here starts its day.
104°Ten minutes in, still warm
A system that’s low on refrigerant, or a compressor that’s getting tired, stalls here — cool-ish on the freeway, warm at the light.
90°Cooling, slowly
A clogged condenser or a weak fan cools at speed and loses ground in traffic. We test both at idle, in the heat.
78°Comfortable at the vents
Most of the way there. A healthy system gets the cabin here in about ten minutes on a summer afternoon.
68°A properly charged system
Vent air between 38° and 45°F, a cabin at 68°, and the same again in August. That’s what we write on your invoice.
The Tucson numbers
Summer here is hard on air conditioning.
Refrigerant doesn’t get used up. If the air is warm, something is leaking or failing — and we find it before we fill it.

Services
Everything between the compressor and the vents.
Air conditioning, heat and defrost for every make, on R-134a and R-1234yf systems. Every price is a starting point we confirm in writing before we open the system.
A/C performance check
Vent temperature, high- and low-side pressures, a UV dye inspection and a look at the belt, fans and condenser. Free with any recharge.
$89 · 45 min
Recharge by weight
Evacuated, held under vacuum to prove it’s sealed, then charged to the ounce on your car’s label — R-134a or R-1234yf.
From $189 · 1 hr
Leak detection
UV dye and an electronic sniffer find the leak — O-rings, hoses, service valves, the condenser — with photos of what we found.
$129 · 1 hr
Compressors & clutches
Clutches that click on and off, bearings that grind, compressors that quit. Replaced with a new drier and a flush, so the new one lasts.
From $1,150 · same day
Condensers & cooling fans
The radiator’s twin up front, where road debris and bent fins steal the cooling. Fans tested at idle, where Tucson traffic finds them out.
From $640 · 4 hrs
Evaporators & valves
The cold part behind the dash, and the valve that feeds it. Musty smells, frosted lines and warm center vents all lead here.
From $780 · 1–2 days
Heat & defrost
Heater cores, thermostats and blend-door actuators — so the windshield clears on a cold January morning in the foothills.
From $280 · 2 hrs
Blowers & climate controls
Blower motors, resistors, pressure switches and the climate-control faults that come and go. Scanned and tested, never guessed.
From $240 · 1½ hrs
Cabin air & odors
A new cabin filter in ten minutes, and an evaporator cleaning when the vents smell like a gym bag. Monsoon dust makes this a twice-a-year job.

How your A/C works
Where the cold goes missing.
Your A/C moves heat out of the cabin in a sealed loop. Warm air means one of five parts has stopped doing its job — and each one leaves clues we can measure.
1CompressorSqueezes the refrigerant and starts the loop. A clutch that clicks on and off, a grind or warm air at idle point here.
2CondenserSits in front of the radiator and sheds the heat. Bent fins, debris or a failed fan leave it hot in traffic.
3Expansion valveMeters refrigerant into the evaporator. When it sticks, one line frosts and the vents run warm.
4EvaporatorThe cold part, hidden behind the dash. A leak here shows up as a musty smell and dye at the drain.
5Hoses & sealsWhere most leaks are: O-rings, service-port caps and hose crimps. Dye and an electronic sniffer find them.

A visit
From warm vents to cold air.
1
Feel the vents with us
Tell us when it goes warm — at idle, on the freeway, after twenty minutes. A thermometer goes in the center vent the moment you arrive.
2
Measure, then find the leak
Pressures, UV dye and an electronic sniffer find the fault. You get photos and a written estimate before a part is ordered.
3
Repair, then recharge by weight
We fix the cause, hold a deep vacuum to prove the system is sealed, then charge it to the exact weight on your car’s label.
4
Cold air, on the invoice
The vent temperature goes on your invoice. Parts and labor carry a 24-month / 24,000-mile warranty.
Field notePressures and vent temperature go on the job sheet before anything else.
Why Cool Front
Measured, never guessed.
Gauges before guesses
Every visit starts with pressures and a vent temperature, written down where you can see them.
Dye in every recharge
So if your system ever leaks again, the leak shows itself instead of hiding.
Charged by weight
To the ounce on your car’s label — never topped up by ear, and never from a can.
Both refrigerants
R-134a and R-1234yf equipment, and the right oil for hybrid and electric compressors.
Every repair carries a 24-month / 24,000-mile warranty on parts and labor, written on your invoice — along with the vent temperature it left with.

4.9★★★★★from 870 Google reviews
Two shops recharged my car and it was warm again by July. Cool Front found a cracked condenser, showed me the dye, and it’s been ice-cold for two summers.
They wrote 39° on my invoice. I checked with my own thermometer in August. Still 39°.
Same-day A/C check in June, which in Tucson is a small miracle. Fair price and no upsell.
My defroster barely worked last winter. A $280 blend-door actuator later, the windshield clears in two minutes.
They explained why R-1234yf costs more, showed me the label under the hood and charged exactly the quote.
The team
Three people who know your vents.
A small shop on purpose: the person who measures your car is the person who calls you about it.
Luis Arriaga
Owner · ASE Master Technician
Opened Cool Front in 2009 after ten years of dealership A/C work. Measures every car’s vent temperature himself on Saturday mornings, and still writes it on the invoice.
Janelle Brooks
Diagnostics · ASE certified, A/C & electrical
Finds the leaks nobody else can, with dye, a sniffer and patience — and the climate-control faults that come and go.
Sam Whitehorse
Service advisor
Books the same-day slots, sends the photos and the estimate, and makes sure your car is cooled down before you get back in it.

Can’t I just top it up with a can from the parts store?
A can adds refrigerant without finding the leak — and often too much, which can damage the compressor. We measure, fix the cause and charge by weight.
My car uses R-1234yf. Can you service it?
Yes. Most cars built from about 2017 on use R-1234yf, and we have the equipment for it and for R-134a. Your quote names the one your car takes.
How often should the A/C be serviced?
There’s no fixed schedule — a sealed system doesn’t use refrigerant. A check each spring catches small leaks and weak fans before the first 110° day.
Why does my A/C smell musty?
Moisture and mold on the evaporator. A new cabin filter and an evaporator cleaning usually fix it; if it comes back, we check the drain.
Is it safe to drive with a noisy compressor?
Briefly, with the A/C switched off. A seizing compressor can shred the belt that drives other parts too — so keep it off and book soon.
How long does an A/C repair take?
Checks take about 45 minutes and most recharges about an hour. Compressors and condensers are usually same-day when the part is here by 10 a.m.
Do you fix heat and defrost too?
Yes — heater cores, thermostats, blend doors and blower motors. Tucson winter mornings are short, but a windshield that won’t clear is still a safety problem.
