One of my ac units stopped working so I did a little research to find a good technician. I wanted a locally owned and honest person to work with, and I’m so glad that I found Tim and Schiller Services! Tim showed up within a couple of hours after I called him, took about 30 minutes, and the ac is up and running. I also appreciate that he took the time to explain, and show me the parts, that needed to be replaced. Great guy, great service! The 5 star reviews are 100% valid and Tim will be the first person I call when we need additional help with any HVAC issue. Thanks so much for doing business the way you do!

Tim has helped me and my family out on short term notice numerous times. Quality work and very honest. Can’t recommend them enough

Tim is by far the best air conditioning contractor I have met. When I need a furnace or air conditioning company, I always call them. They are very fair and honest. I recommend Schiller Services to all my friends and family.

My wife and I couldnt be happier with Schiller Services. I highly recommend them. They were professional, attentive to our needs, and honest. We received excellent service and advice, with no pressure to make unnecessary purchases. Our HVAC system is old, but Tim had it running like new quickly, and - at our request - helped us devise a strategy to improve its efficiency and plan for an eventual upgrade that falls within our budget. We will absolutely call on them again.

Tim is a great guy, he is so professional. If he tell you he is going to be there he is. Great service, he is my A/C and heating guy froM now on.

We had Bryan from Schiller out to give us a second opinion on an issue we were having with our upstairs HVAC unit. He came on short notice on Friday afternoon to diagnose the problem and he was able to get it fixed Monday morning which was the soonest he was able to get the part. The service was top notch and both Bryan and Tim we very friendly and professional. They ended up saving us $1,600 from the first quote we got. They truly put their customers first. I highly recommend them.

Absolute best! I texted them at 10pm for a non-emergency issue and they were here the next morning working on it. We had 2 contractors give us the run around for the same issue but Schiller services took care of it right then and there. They also recommended a great plumber for the plumbing part of the job. Bryan explained everything in detail and even Tim called and explained it again and made sure all my questions were answered. They have a man for any job needed to be done around the house. Im so glad I dont have to spend time researching every time something needs to be fixed now. Thank you Tim!

I used them a couple years ago and knew of their stellar performance and ethics. So when my A/C had a problem I knew just who to call. Dependable, knowledgable and cost efficient. A few hours later I was nice and cool with my A/C running. Cant beat that.

We interviewed 5 A/C companies in 3 days. So glad we did. Tim’s honesty on exactly what we needed — and what we did not —— saved us thousands over the other guys. He was on time, diligent, and done. Total pro. His helper Brian was knowledgeable, professional and a veteran of the US Marines.If you go with ANYONE else — before talking with Tim — you’re not getting the whole picture and you’ll be told something unnecessary that’ll cost you. PERIOD.A+ happy and chilly 🥶,The Foresters

We have had Tim come out for AC checks twice now. He is by far the most honest guy we’ve had out for service. He took the time to explain everything to me and even showed me the part that needed to be replaced. He has always been available! We will continue to contact him for our AC/ heater needs.

Great job today at fair price.Also the owner came back personally to inspect the job and confirm I was satisfied. No AC owner has ever done that for us. I would highly recommend.

Tim and his team are honest, friendly and really know their work. He has worked AC’s not only for my family and clients but installed several large units at our new offices...Schiller Services is one of the best out there and always reasonable and trustworthy!

I’m so glad i called Tim to fix our faulty kitchen lighting! I have all working lights (it’s been 3 years and my home warranty company couldn’t fix them) and he made it happen within a day of contacting him! So so pleased!

Tim and Schiller Services is a great company to deal with. They are punctual, friendly, honest, and knowledgeable. I recommend them for all of your AC & heating needs!

Had an emergency and gave Schiller a call.. I was afraid it was going to cost to much but they were definitely the most affordable AC repair in Spring. Really happy I was able to get things fixed!

Tim is excellent man! Seriously! I havent been happier with the AC services this company provided. It was a little bit of trouble at first finding the right company to go with in Houston, but I am very glad I found Schiller!

Exceedingly honest!! Exceedingly Competent!! My air conditioner was blowing, but not cooling. I called and spoke to Tim Schiller who answered the phone. I advised him that my air conditioner was 18 years old and that it was not cooling. He stated, Lets see if we can repair it so that it will last another 18 years. I COULD NOT BELIEVE MY EARS !!! WOW!! HOW HONEST CAN YOU GET? A repairman arrived within TWO HOURS. He diagnosed the problem within 15 minutes. He advised me that my Capacitor was only putting out 20, when it should be putting out 50. He replaced it and showed me the old capacitor and he showed on its side that the Capacitor requires 50. Then, he used a current-measuring machine to show me the output of the old capacitor. He performed maintenance on my air conditioner as well. Total cost: $250.00!!! AMAZING!!!I AM ECSTATIC!! I AM SO HAPPY!!!

Hey Tim! Thanks again for the great work you did on my air conditioner! Really happy I found you local here in Spring.. and thank you for being so affordable! :)

Thank you so much for the maintenance you did on my AC! Really appreciate it! Check these guys out! Definitely the best in Houston!

Awesome, quick, & affordable! These guys were truly professional & delivered on their word. If you’re looking at other companies for your A/C, Heating, etc. needs, don’t . Pick up the phone & call Tim today!

Pur AC was leaking and caused a leak in my ceiling. It was 9 PM in JULY!!!! I contacted Schiller Services and there was a tech at my house by 10 AM the next morning! After a thorough inspection the tech discovered that the drain lines were clogged. Through some small talk during when he first arrived I had told him my husbands family was in plumbing. The tech was kind enough to tell me the issue was something my husbands family would be able to fix instead of charging me an arm and a leg to do it. All I had to pay was the service call fee, which was very reasonable, especially considering it was July and they were so quick to respond. The tech was friendly, professional, and honest and Tim, the owner, was also excellent to work with. I HIGHLY recommend Schiller Services.

Schiller Services has to be the best AC maintenance company in Spring! Really happy with the services I received! Thanks again so much!

Lightening fast service, fair price. These guys are awesome.

Tim is professional & honest, which is difficult to find these days. He will diagnose & explain the problem(s), provide mult options, and wont try to sell you things you dont need. 100% recommend.
