Emissions and Smog Testing

At Hall's Automotive, we help our Tucson customers' cars run as cleanly and efficiently as they possibly can. We provide a range of emissions testing services to ensure that your car is running and driving its best, as well as complying with all local smog regulations. Should a problem arise with any of your vehicle's emission systems, we provide the parts and expertise to get you back on the road. Hall's Automotive can replace mufflers/catalytic converters, refill diesel exhaust fluid, and make sure the full range of filters in your vehicle's exhaust system are working perfectly.

Regulators understand that older cars simply can't meet modern emissions standards without extensive modifications. For newer cars however, passing a smog test is a requirement of road legality. Call us at 520-790-1885 to learn more about the emissions requirements for your vehicle.

Emissions testing (also known as smog testing) is a vital part of the maintenance of your vehicle. E-tests provide your mechanic with important information about your car's engine and exhaust system. If important components, like your car's catalytic converter aren't working properly, the car isn't running as it was intended to by the manufacturer. Inefficiency costs you extra money in fuel and does unnecessary harm to the planet. Emissions testing can also affect the value of a vehicle you're trying to sell; while you can still sell a car without a valid e-test certification, you'll get more money for one that has passed the test.

There are several reasons that a car may fail its emissions test. There may be a problem with the vehicle's fuel system adding too much fuel to the air-fuel ratio required for proper combustion within the cylinders of the car's engine. This is known as "running rich" and results in the smell of gasoline from fuel passing through the engine and exhaust system without being fully burnt. Causes of this issue range from faulty fuel injectors to issues with the engine's control computer. There may also be problems with oxygen sensors or the vehicle's ignition system. At Hall's Automotive, we use a complete set of diagnostic equipment to determine the problem and fix it quickly, explaining every step of the process to you, our valued patron. Call us at 520-790-1885 or send us an email to arrange a health check for your car's emissions system today!

-Jerry H.

Very good shop. Nice people. And they do good work FAST, even though they were super busy they got me in and out of there. Larry's shop, Halls automotive, is hidden away in the cut but I would definitely use this shop again. I recommend that my people with car trouble now or in the future check them out.

-Chris P.

I brought in my 2000 Volvo v40 and they knew exactly what to do with it. They fixed it up in no time and it was excellent customer service and kept me updated. Highly recommend this shop they did a fantastic job at fixing my problems on the car!!!


-Alexis A.

I've taken my truck to them a couple of times now and have had a really good experience. They're very responsible with the price, they have many years of experience and are very professional. I will be a lifetime customer.


-Todd B.

WOW. MY TRUCK RUNS SO WELL! The service was excellent! I was preparing my truck for my 16 year old and wanted her to drive a problem free vehicle. I was lazy and didn't maintain my truck very well. Hall's Automotive did so good at fixing it up that I have them do all my work now. You will get a fair price. You won't be sorry.


-Marc R.

Where to start, I came to Larry with a nightmare of a project. I need a complete engine rebuild, clutch, steering rack, transfer case, rotors, brakes pretty much if was on the car it needed to be replaced. The car had sat for two years and basically was a shell of broken dreams. Larry and his incredibly friendly and efficient staff too the project and quoted me a time and date sure enough they delivered. This job was not for the feint-of-heart. Hall's Automotive definitely made a life time customer and will have my business from now on. I HIGHLY recommend this shop from projects large to small.


-Anthony H.

Honest, kind mechanic. Trustworthy and decent with appropriate prices. Not the cheapest but someone you can use again and again.


-Matt & Natasha B.

I definitely recommend this shop. Great service! I was able to get an appointment right away, they fixed my car in one day, and with a great price.


-Chrissy M.

I was referred to Larry by the shop (BrakeMax on Pantano) that I take my mid 60's Corvette to for oil changes. I needed help with tune-up and minor repair work. Finding a auto repair shop that works on old cars isn't easy. Larry took care of all the issues the old car had, as well as giving the old car a mechanical look over. I highly recommend Hall's Auto for your car needs.


-Michael H.

I would recommend Halls automotive to everyone. Larry did such an amazing job fixing the engine of my truck and at such a reasonable price too. I only go to Halls, even for simple maintenance checkups.


-Jenny C.

While passing through Tucson, my car (a 2003 Crown Vic) began making a horrible noise that made me halt my trip home to the Northwest in fear of breaking down in the desert. After explaining all that, Larry agreed to see me as soon as I came in. We hopped in the car and he diagnosed the issue immediately and had me ready to go promptly. I didn't actually need a repair (non-essential ac component I didn't care about in my hurried trip home) and he let me go FOR FREE with peace of mind after explaining everything in great detail. I suppose my only complaint is that I can't find such an honest mechanic in Oregon. I only hope that you, the review reader decide to trust halls with your repairs.


-Elijah H.

Was passing through Tuscon on way to San Diego and my axle bearing broke. I googled a mechanic near me. Called Halls automotive and Larry was able to provide a little bit of insight on what to do. He even suggest a tow company in which he trusts. The tow was very reasonable. Once the car got it into his shop he was able to take a look at it, give me an estimate and fixed within a day and a half. Larry even updated me on what exactly he was doing and why. One of his mechanics even gave me and my 3 year old a ride to the hotel. Larry didn't just "FIX" the broken part (which I think the last mechanic did) he brought parts in from different places and chose the best one for my dollar. After everything was fixed, Larry assured me i wouldn't have this problem again. I 100% trust he did a amazing job and in a reasonable amount of time also. Thank you Halls Automotive!
