Reviews of local pros in Leander, Texas

My heater stopped functioning right in the middle of freezing temps. I was certain I’d have to wait for days before it would be serviced. However, Dalton Air worked me in that very same day and found the problem quickly. Thank you Dalton Air for keeping me warm.

Absolutely fantastic service. They are easy to work with, fair, and reasonably priced. I’ve used them a couple times, and plan to continue. Great service in the Liberty Hill area.

Lewis was great. We have a unique AC system that many don’t understand. Lewis figured it out quickly and had our AC running within 10 minutes. Excellent job!

Tabor came by to help get our heater up and running again during the 2026 Freeze. He was extremely knowledgeable and was able to identify the issue quickly. We really appreciate him coming by and fixing our heater giving our family much needed warmth during this cold time. Thank you again Tabor for the swift help. Also thank you Louis for setting everything up and getting us taken care of. Highly recommended!

We were having some heating issues with our unit over the recent freeze. I reached out to Dalton’s Air as they had done a great job in the past with our unit.

I got a quick response to my call asking about my situation. We scheduled an appointment.. Tabor Came out and quickly identify the issue and resolved it on the spot.

Dalton’s Air is my go to for any of my HVAC needs 😀

I've known Lewis Dalton for decades and he has been the one I have turned to for my commercial building and home. He is always there in less than a day and we are backup and running. Pricing has always been reasonable and replaces and fixes only what needs to be done to get you backup and running. I give Dalton Air my highest praise and recommend him to everyone.

Louis Dalton has always been honest, dependable and knowledgeable. I've used many HVAC companies and they always want to over sell you something you don't need. Not Dalton, you get what you ask for. Will only recommend fixes as needed. My wife is in real-estate and recommends Dalton to all her clients. Mario Rangel

James Shaw is professional, quick, and knowledgeable. I'm looking forward to the membership and continued services.

Timely and great service! You can’t go wrong with the “ Double ‘J’s’ “- James, and Jesús. Super friendly, and they just get after and get the job done… Take a chance. Give these guys a call. Thank you

My AC went out the day before and after calling a few places they couldn’t come out for days. JW arrived a few hours later and fixed my issue very quickly. Would highly recommend!

JW is a real pro. I had 2 different quotes and JW was able to find things that other companies didn’t even notice, which were causing the main moisture issue (I checked with my builder and they confirmed it). They have a knowledgeable team, and they are professionals. Highly recommended!

Jason J, our technician was amazing and very informative. Because of his service we are declining other companies’ annual service offerings and definitely want to sign up with the One Hour Ac& HVAC. Calling them Monday. Prices seem more reasonable than other’s. Graditude.

JW Johnston with 1 hour got us taken care of quickly! He was professional and polite. He was able to diagnose the problem and get it back up and working in no time! JW went above and beyond, would definitely recommend!

Our HVAC went out in the middle of the night where we keep it 72° and we woke up to 82° sweating. With three little ones under five years old we were in dire need to have somebody come out as soon as possible to fix the unit. I used Google to search for open HVAC systems at 7 AM called four of them and got no answer, the fifth ring was one hour heating and cooling. Tina was able to take quick action and get me booked just three hours later. James and Jesus took quick action in finding the problem and explaining to me the quick fix needed. They were then able to save me 15% off of today’s fix by signing up for a maintenance program where they will come out twice a year to tune everything up and make sure it doesn’t happen again. The speed, quality, and communication when our heating and cooling provided is next level, can’t recommend them highly enough!

Ismael Garcia was thorough and professional in checking our AC system. Highly recommend!

JW Johnston is efficient, knowledgeable, and highly skilled in all HVAC related issues. I highly recommend him.

James was very helpful and professional. Explained everything and answered all my questions. I would certainly call on him again and trust his advice

I called one hour heating and air-conditioning for a quote on duct cleaning. I received outstanding service and a very detailed estimate.

Excellent service. Communication and clarity for the work that needed to be done! Thank you so much, James! Quality you can trust!

Ismael was very pleasant. He arrived sooner than expected, answered all of my questions. I feel confident in the recommendations and information he gave.
