Al's does not answer their phone. I walked in.. all bays were open.. asked for a diesel emissions test. They tried to schedule me for a week later. Drove to Broomfield.. test got done that same morning... for $25 cheaper

Just like walking back into the 70's. I love this type of old school business. The guys are honest, straightforward and do what needs to be done. No BS.

Any time I have gone here it’s always a pleasant and quick experience. Whether it was going in with my grandma to take care of her car, or going in there myself with one of my vehicles. Always a pleasant experience.

Very nice guys running this emissions shop. Had my 93 F350 7.3 NA IDI sniffed this morning. They told me the shops been open since 1991, and you feel the hospitality that comes with that.

In and out in 10 minutes. Owners masked up and felt completely safe. Comfortable shady chairs outside to sit in. I’ll be back next year

I just made an emissions check appointment with Al's for my 2003 Dodge diesel pick up. Danny and Mike provided prompt, courteous, and professional service and I was in and out on time. This is not my first visit to Al's nor will it be my last. I have had the same great experience with each and every visit. I highly recommend this shop for all of your diesel emission needs! Top marks all around to Danny and Mike!

It's nice that we have this place in Longmont and don't have to go far for diesel emissions. Friendly staff and quick!

Staff was nice enough. I called them 5 times over the past week to ask a few questions and they never answered or returned a call. After stopping by they told me they ****don't test newer than 2012****

This is one of the worst places I have been in years. I stopped by at 11:30am to see if they would accept a walk in appointment and they replied no. I have walked in before with never an issue. Therefore, I proceeded to inquire if there is a better time for a walk in appointment such as first thing in the morning, or if they simply have moved away from all walk-ins. Instead of providing and answer to my question, the old, grey-haired man (that usually does the testing) replied extremely aggressively using several curse words including the F-Bomb multiple times. He was essentially telling me (in the most vulgar way) that I was interrupting their lunch and how could I have the audacity to even consider a walk-in appointment despite the fact I have walked into this place successfully for the last 5 years! I have never been treated so UN-professionally at any business that I frequent. I actually feared for my safety!! Beware!! Do not walk-in or ask the wrong questions! If the old grey-haired man is in the office you may face his extremely vulgar and angry wrath!!!

Took my classic Mercedes here. Old-school shop, cash only operation. No worries about lack of competency with manual transmissions here like at the gasoline emissions test stations. The Dyno is set pretty low into the floor, so a lowered car might not be able to be tested here.

Straight shooters, quick and efficient. You need to call to schedule an appointment and pay in cash, an online booking platform would be convenient.
