The young man who serviced the a/c unit was an excellent example of a professional. I received a quick response and quick repair of the unit. No complaints, only high praise!

Keith AC Review Out of the five HVAC contractors we contacted, Keith AC was the only dealer who asked a critcal question: "Does your existing AC system work? It is going to warm up and it can get pretty hot in Texas." I mentioned that the system was not working and we couldn't get it to respond. Keith AC sent a technician to check out the old system.

After running a series of tests, the technician replaced some melted electrical components, wiring, and a large, burned out electrical plug with only one partially melted prong left. Eventually, he got the system working. "This should get you through the next several weeks, " he told me, "if it goes down, call me and I'll come out." "How much do I owe you for the parts and service, " I asked. "No charge, " he replied, "we'll retrieve the parts when we install the new system.

We just want to make sure you have heating and cooling capability until the new system arrives." I was amazed. How many other companies would go out of their way like this for their customers? Keith AC's actions speak for themselves. Their chief concern is the welfare of their customers! Once the new system was installed, it still lacked the "communicating" touch control system which had not arrived yet.

A few days passed and I became concerned. I am a chronic worrier. I sent an email to Keith AC expressing my concerns. The following morning a Keith AC truck pulled into my driveway. Soon, a technician was inside installing an up-graded communicating touch control system. Accompanying him was Keith AC's owner, Brian Keith himself, overseeing the process. Brian had received my email, got directly involved, and secured the up-graded control system. Keith AC was intent on ensuring that any concerns on my part were addressed and resolved to my satisfaction.

One thing has become very clear to me: Keith AC's foremost and top priority is taking proper care of their customers. Their actions truly speak for and back up their words. Keith AC is known for its down-to-earth Texas hospitality, be it also known, given my experience, they are Top Class in everything they do the new system works impeccably. If you are looking for a new HVAC system or service of your existing one, I urge you to include Keith AC in your search.

You will not be disappointed. I believe you will find them to be honest, highly knowledgeable, affordable, and above all, committed to their customers' well-being. Noel Griffin Marshall, Texas

They worked us in quickly- Mr. Keith and Patrick were very kind and efficient. Just a short amount of time is all it took for them to get my AC running well again. Mr. Keith was able to communicate with my husband over the phone about what services/ repairs were done as well as any future maintenance that may be needed. Services: A/C system maintenance, A/C system repair

We have been using Keith Air for 25 years or more. Right off the bat they saved us thousands of dollars in unnecessary unit replacement cost. We have kept an annual maintenance contract with them ever since. They are honest and very pleasant to work with. I always feel completely safe with their employees in my home. Simply the best.

These guys came out to repair my 30+year old equipment. Eventually i bought a new unit from Keith AC and it was a great decision. Smooth quiet operation also save about 50 bucks a month on my electric bill. Cant say enough about the owner and the employee's. Honest, dependable. On time. Fit me in at the last minute. They really make the customer feel important.

Heat went out in a 10 degree deep freeze. The Keith technician was brilliant and skilled. Got the heat working within two hours at a cost of $275. He crawled under the house in the freezing cold and replaced a heating coil. He is a straight shooter, honest and did not try to sell me anything. This company is excellent! I highly recommend them.

I don't normally leave reviews but felt like I needed to because I was so impressed by the quality work, professionalism and personality of Keith's AC and repair. As a 30 year Naval veteran, I have lived all over our great nation, and overseas. so, I know great service and professional work when I see it. I will admit, it's been challenging finding it here in our local area, but I definitely know who to use for AC/heat repair for my home and business. Brian and his team are extremely professional and efficient, and I think you would be very surprised with his competitive pricing.

He does also take CCs which I know can be helpful with last minute expenses. Trust me, if you need anything dealing with AC/Heat/Duct work, Keith's AC and his team should be your first call. Thank you. V/r, Ken LCDR(ret), USN p.s. They did all the concrete work, wiring and everything that you see in the pictures. Top notch work without breaking the bank!
