I found At Temp doing a simple search for HVAC companies to replace my failing system. I noticed At Temp had good reviews so I included them in the multiple bids I got before getting the work done. I chose At Temp over some of the larger companies who quoted because the owner (Louie) seems knowledgeable, sincere, and fairly priced the work. He always remained in good communication with me through the process. When it came to the day to complete the work he had brought in 3 additional guys to assist with the job. They finished the work in a timely fashion, left my place reasonably clean, and were polite through the whole process. Louie will definitely be my first call for future work and highly recommend considering using At Temp for your future HVAC needs. read more

(Cross posted on Google) Smelled a acrid burning odor though the house and then the circuit breaker popped for the furnace. When I reset it it instantly popped off again. Not good. I took a look at the furnace, a 18 year plus old Armstrong, pulled out the blower assembly just out of curiosity. I could smell the motor was a little smoky and could smell that familiar smell. I flirted with maybe trying to change it out as there are so many YouTube Videos making it seem easy. However when I looked for getting the motor on my own it was days or weeks away and close to $400. I called a large HVAC company that quoted $850 total for a motor. And they could come in a day. I said go ahead. Not happy but did not want to gamble in the winter with a terrible shortage of parts. they called me back 10 minutes later to say they would need and extra $50 if I wanted the work done in less then a week!! This is a company I have used and they have 50 plus service trucks! Not a small shop. So $900 for an installed electric motor! I felt I was being taken advantage of. So I looked up an authorized Armstrong service contractors. I call AT Temp and so glad I did. Louie the proud owner actually picked up between jobs. Had me text him the model number and he verified inventory. Said he could do it that day by the end of the day. There was on two motors left so he picked it up earlier in the day! Game by at 4:00 on time and installed and checked it out for $625 total all in! Brand new out of the box and as promised. So glad I found him. He is the owner and actually the one doing the work. Very impressed with professionalism. I will recommend and use for us and others. I love to support small businesses when I can. Looking at the wiring I think "What was I thinking I would do it :-)" read more

I submitted a Yelp inquiry about my AC line freezing up on a Sunday and Louie was one of the first to respond. He offered some tips to try and fix the problem on the phone. It turned out my unit was low on R410A so he came out and topped it off. He then recommended a low-peak time to return to hunt down the leak. He seems very knowledgable and honest. read more

My heater went out on over the weekend and Louie saved the day.  He gave advice over the phone without hesitation to see if we could come up with a fix.  He ended up coming the same day and troubleshooted the furnace before even thinking about recommending a replacement.  He tried many different techniques until we had a safe resolution to get some heat.  Not only did he fix my old furnace, but he checked in the next day to see if everything was ok.  Highly recommended. read more

My tenant's AC stopped working in our Condo Unit in Chicago; I put in a quote request on Yelp, and Louie called me within minutes. He came to the unit and was able to find the issue and replace the capacitor all within an hour. The price was very reasonable and he was very professional. Will definitely use him again in the future. read more

Extremely pleased with the service provided. Louie was prompt, courteous, professional, and did a great job. He was even willing to come back later in the day when we were unable to access the building's roof to inspect (and repair) the compressor. Rates seemed reasonable for the services provided. read more

We had the misfortune to find ourselves on the Friday night before the New Years holiday without any heat blowing out of our furnace. It was 9:30 pm and I did a frantic search on Yelp for a Heating and A/C company that advertised being "open 24 hours" since my regular guy didn't have leave an emergency number in order for me to contact him....and this WAS an emergency with temperatures estimated to be below zero that night. I called 3 different companies. Louie at At Temp Mechanical was the only one to actually answer his phone (Yea! The others went straight to voicemail.) and not only could be come out, he could be at our house within 15 minutes as he was finishing up a job one town over. Louie showed up as promised...had the problem diagnosed and resolved within 5 minutes...and then spent some time giving the furnace a minor clean up. He was professional, efficient, gracious and best of all -- reasonably priced for a service call at 10 pm on a Friday night. I love my regular heating and a/c guy, but Louie...I'm thinking of throwing him some of my business just because he was there when we needed it, did an A+ job, and didn't hold us hostage on the price due to it being 'after hours'. FYI: It is interesting to note that one of the companies that eventually did call me back advised that 'open 24 hours' really means -- we'll get to you WITHIN 24 hours...ah-huh...I don't think that's what the general public thinks... read more

Louie is very easy to work with, always providing prompt service all at a fair price. I've used him for a handful of jobs, both residential and commercial properties, and consider him my first choice for HVAC services. read more

Louie is a rock star! Week earlier it was 40 degrees - fast forward to Memorial Day weekend - 100 degrees in the shade - and sadly a malfunctioning AC. Louie came on Sunday within a couple hours of my call and took a look and gave me some pointers to get me through the weekend. Came back on Tuesday armed with a solution and I'm living large in cool comfort again. He didn't throw parts at the problem but really worked to figure out what was wrong - turned out to be the fancy Nest thermostat. He fixed the problem was really nice and very knowledgeable. Price was extremely fair too! Highly recommended! read more

I created this account just to give Louie a good rating. Louie was the first to respond to a quote request for an HVAC repair and was competitive with the others. What set him apart was how fast he responded via email, text, and phone. His availability was awesome and he was right on time. My unit didn't end up really needing repair as it just over heated, but he didn't try and charge more for the visit and gave a detailed explanation for next steps and possible reasons why it was over heating which I really appreciate. I have a problem with an air condition unit at another building and am going to have him look at it as well. read more
