Austin Residential & Commercial Heating
I would like to first thank you for considering The Coolest LLC for all of your HVAC service and installation needs. My name is Mark LeGare, my friends call me "Air LeGare." My journey into the world of heating and air conditioning began with my unlikely enlistment into the US Army at the age of 17 as a 52-C Utilities Equipment Repairman.

During my enlistment, I was deployed to Kabul, Afghanistan for Operation Enduring Freedom in 2003. At the end of my enlistment in the Army, I decided to return to Afghanistan as an independent contractor, once again lending my services to combat operations. I spent many months traveling around to the Forward Operating Bases in the mountainous regions of Afghanistan, lending my budding HVAC skills to soldiers based on the front lines.

The Coolest saved us again in an emergency (heater out with the threat of freezing temperatures looming)! Travis the technician who came out today was very professional, knowledgeable, and he worked quickly and fixed the problem we were having just in time to keep our house warm for another freeze. Great value. Great service. Love that they're locally owned and run. Can't recommend The Coolest enough. Never been disappointed with any of the professionals sent to our home. We're TC customers for life.

Mark and the team The Coolest were great. I tried contacting a few other companies, and none of them were able service both airhandler/ductwork as well as mini split systems at a commercial property. I finally stumbled on The Coolest in a Google search, and they were able to do everything I needed AND get out to our office in a timely manner. All the work was done in one day in about 5 hours, and I felt confident in the pricing that they gave.

We inherited an ancient HVAC system when we moved into our current home. We used The Coolest several times to fix small problems before ultimately deciding to replace the entire system. Throughout the entire process and since then (they’ve been back to fine tune and fix a few small issues) the team was professional, capable, communicative, timely, and kind. Travis, in particular, has been amazing— he’s fast but careful, an amazing diagnostician, clearly incredibly knowledgeable, and wears a mask every time he enters our home. He goes way above and beyond making sure everything (not just the

I contacted 9 HVAC companies in Austin for a complete replacement of my residential system. I received bids from 7.5k to 15k for the same type of system. How can the same system cost twice as much. The answer is overhead. Incredible. The Coolest LLC not only beat the best prices out there, they provided a no-nonsense interaction in which they did not try to price haggle or up-sell me on anything. I knew what I needed and they provided the most competitive price for a "brand name" (Bryant) system. They have a 10 year warranty on the system parts and a 2 year warranty to back up their work.

The Coolest Team has been with my whole homeowner experience. They fixed my old unit giving it at least 3 years and extending it well past it's life expectancy. Now it's time. Everyone who has come to my house has been wonderful and professional. I'm so excited about my new unit! Thank you The Coolest Team 😎

I used The Coolest LLC at my business recently and I have nothing but great things to say. From the first phone call to the service I received, the whole experience was magnificent.
I talked with Mark on the phone and told him about our issue, and he assured me he could have a serviceman at the location within 24 hours and there would be no emergency fee (the other company I called said it would take 3 days or I would have to spend an additional $150 rush fee!).
Travis came out to my store, and within 20 minutes was able to identify the issue stopping my AC from working. After about an hour in

I can’t say enough about how great Mark and his team was! We reached out when our AC unit started struggling really hard. It was mid-summer so I was prepared for a few days wait before getting service but somebody was out first thing next day. They were very straightforward with their assessment of our system. Being an older unit, repairs would have been frequent and possibly never fully work so we opted for a new system. Their pricing was very reasonable and Mark did a phenomenal job explaining the pros and cons of each option. When it came time to install they came out the very next day and

Working with The Coolest was a great experience all around. My AC stopped cooling over the weekend (in the middle of August, woof), so I called The Coolest on Monday morning at the recommendation of a co-worker, and they came out the same day. They found the problem right away and talked me through the available options and associated costs. Everything made sense and costs were very reasonable. They even double checked to see if my unit was still under warranty (of course it was a year past). If you've been digging through reviews for a good HVAC company, save yourself some time and just call the

Didn't think I'd end up leaving a review for an AC company - but these guys are killer. Have already recommended to multiple colleagues at work.

I love these guys. They saved me in the dead of summer a few years back when my AC went out. They showed up that day and cranked it out. So of course when I bought a new house and it needed a new HVAC system they were the first I called. They got me in within a week and did a fantastic job. They truly are the coolest.

Marvelous Mark and Coolest Services were wonderful from start to finish. We’ve actually trusted them to service our A/C needs for the last two years. Each time was top notch. Mark was thorough, extremely knowledgeable, had a kind demeanor and didn’t try to over diagnosis our issues or upsell me at all. An insignificant detail but definitely went noticed, without my prompting, he considerately removed his shoes at the door seeing that was our family practice at home. I have Coolest Services saved to my phone and will continue to use and recommend them in the future if needed.

The Coolest exceeded my expectations in service. My AC stopped working in a heat wave and they were the only company that could get to me the same day when other companies had a wait for days to a week later.
They're also extremely friendly and easy to work with-great communication and reliability made it stress-free once I reached them.

I spoke with Knute on the phone and messages for updates, he was great coordinating with my HOA to get access to my rooftop. My technician Dagan was also wonderful, he was very personable and explained everything. Such a friendly bunch that delivers. In

I've been in field engineering for 15 years and there are golden rules:
NEVER throw parts at a problem.
ALWAYS diagnose the issue using a multi-faceted approach of symptom-cause-fix-confirm.
Confirm with the customer their options before executing.

We had a electrician in our home yesterday doing some work. While up in our attic he noticed that our AC drain pan was leaking and the unit didn't look right. He was under no obligation to tell me about what he saw, but he did and I am so grateful. Cue the panic though...AC issues in Texas? That's immediately a scary thought especially as we are gearing up for the summer heat.

I called a few companies but got all voicemails boxes. Frustrated, I went to yelp and found The Coolest. Someone immediately answered and although he couldn't get someone out to my house yesterday, he scheduled

They have been a pleasure to deal with from getting a quote all the way through installation of my new AC units.

The Coolest was able to send a tech at noon on Saturday right after the winter storm moved through Austin, and confirmed that my downstairs blower furnace was dead. They quoted a very competitive price, and Mark provided all the details on what was to occur during the AC replacement. He even did the energy rebate paperwork for me.

Curtis and his partner showed up at 9am on the day of installation, and they were both very diligent about the work they did. Everything was completed on

The Coolest lives up to their name. I had a unique install (minisplit in a railroad caboose), and agonized over a couple of details. Mark assured me this install was going to go just fine, and he was he right as rain.

I think some of his confidence must come from his trust in his team. The installers were consumate professionals, who knew the systems well, finished in record time, and explained it to me clearly. Kudos to them!

I'd be happy to use The Coolest again.

Mark and team have been amazing to work with.

Being a first time home owner, selecting a new AC/heating system seemed pretty daunting. Mark took the time to take me through my options -- the pros/cons of certain systems, what would qualify me for the best rebates for the city etc. I took the time to secure 2 others quotes, and hands down, the information and customer experience I received from Mark was above and beyond what I experienced from other companies.

During instillation, a curve ball was thrown from the my earlier system. The team was creative in finding the best path forward and pushed

If your AC is acting up, you MUST call them!

I've been meaning to write this review since the second week of August - aka hottest week of the summer. My AC started breaking down in the spring.
Unfortunately for me, I called a few other companies first and had 6 service visits from other companies before calling The Coolest. (I'd been getting patch jobs for 6 months from the other places, which helped for 1 - 2 weeks only).

The Coolest gave fast, friendly, efficient and HONEST service! My calls, emails and questions were answered right away, and I was never put on hold. Most importantly
