Almost hit me. Driving very crazy on the road in Killeen. I will not be using them for services if this is how they act on the road. 10/30/2025

A stand-up guy who stands behind his work mr. Mark is awesome!

I scheduled with a service tech in the morning and he did not show up or call me. Both the design air and tech did not answer the phone. I do not recommend this company.

Wonderful people to work with. Knowledgeable, conscience, professional. Doesn't use "bandaids", keeps with it until the job is completed and done right.

Mark came out to fix my AC,added 3lbs of freon before he cleaned the coils so that the gages would read correctly.House still wasn't cooling like it was supposed to,he said it could possibly be a problem with my ducts.I asked him for a quote of the price which I never received.I contacted my honest friend who is a ac Guy and he found out what the problem was,coils were filthy,ac was overcharged by 3lbs of freon,and it needed a txv.I was charged $782 by Design Air and my ac was still broke.

We are always provided dependable snd professional service from Mark and all of his associates. I highly recommend their services to anyone who have HVAC issues at home.

they are awesome.
Mark performs top quality work, he's always available, he's friendly and most importantly he's honest.
i'll never use another A/C tech while in Houston.

Very professional shows concern when my air was out. Was willing to come back on the weekend if I had any problems, very knowledgeable. Pleasant. Trustworthy
If you need AIR don't go nowhere, keep in mine call DESIGN, he will get you going and your AIR BLOWING!!
BEST DECISION I MADE

Highly recommend for routine A/C maintenance! Not the cheapest around, but worth the extra. He was very thorough and cleaned everything inside and out. Took before and after pictures, and even took videos to show me my unit and how things worked. Very happy with his work, and will be using him again for fall maintenance.

Mark installed my AC unit 7 years ago and I have been using him ever since. Response time is amazing, especially for the hot summers in Houston.
Great customer service.

First class service, blown away by the professionalism and knowledge base of one of their younger technicians Michael.
I highly recommend this company for any of your air conditioning needs. Pricing is comparable to all other companies but slightly on the higher side. Premium service is never cheap, you get what you pay for.

Mark is one of the best in business! Honest and reliable person you can count on with any AC questions or issues. Highly recommend!

Mark with Design Air has been my HVAC consultant, installer, and repair expert since 2004. He came highly recommended from a very good friend of mine. His work is professional, timely, and fair priced. Mark and his team have done a fabulous job keeping all my systems running a peak efficiency. Mark also installed two hot water tanks for us when our original ones failed. If you want an HVAC professional that you can trust call Mark at Design Air.

Design Air is a fantastic, honest company. Mark goes above and beyond for his clients and you can tell he genuinely cares about his business and about locating the cause of any problems, as opposed to band aid fixes. Design Air has been my go to since I moved last year. Mark has performed AC inspections, installed HEPA filters and housing units in the attic, and performed maintenance and trouble shooting on my AC units for me over the past few years and I cannot recommend him and this company enough. Wish I could give more than 5 stars!!
