Keller Services Heating and Air Conditioning

So great! Nils was knowledgeable and professional: not in a hurry, not pushy, just eager to help and to share what he knew. He gave great advice, told us how we could fix things ourselves, told us how he could fix them. Exactly the kind of business we were looking for, and looking forward to using them for years to come.

Brian was a very personable and knowledgeable technician who came out to our house. He was very helpful and straightforward in his work. Highly recommend this company!

We are senior citizens living on a fixed income. We will only trust KELLER SERVICES for our heating/AC from now on. We had been using another (large) company that our builder used for many years, but they suddenly shut down and subsequently reopened - apparently under new ownership but with the same name. The last time they came to do maintenance, not only did they do a poor job but ominously noted that various components were worn and wrote "Breakdown and/or failure is expected in near future" along with a recommendation that we replace all three of our systems at a discounted price of over $37,000 (price valid only for one week, by the way).

We called KELLER SERVICES and Brian came out to inspect our systems. He also completed work that the other company failed to do: (1) cleared a blocked drain (which the other company failed to notice, (2) closed a filter door on a unit (that the other company left standing wide open), (3) secured the filter doors on all three units (the other company left the screws on the floor), and (4) washed all three systems (apparently that's not part of what the other company considers necessary for maintenance).

In addition, he replaced only ONE part rather than arm-twisting us into spending $37,000.

It appears that other company has no qualms about trying to take advantage of seniors using scare tactics. KELLER SERVICES has integrity and doesn't operate dishonestly. Brian gave us the facts about our systems straightforwardly so that we could understand and decide what we wanted done. We appreciate his honesty and obvious pride in his work. We'll only use KELLER SERVICES from now on!

I had been using Keller services to maintain my HVAC and provide my seasonal check ups. This spring the unit was very low on coolant.

After some investigation the coil in the attic was shot and leaking. Being 22 years old a decision had to be made. I could either replace the coil, replace the coil and the outside unit or replace the whole system. I was given an estimate to do all three and as far as the whole unit being replaced, I had several options to choose from.

I chose to replace the whole thing being it was so old and I was actually in the middle of remodeling my home so I figured why not. Brian discussed all the options and I went with the 18 seer variable speed unit. Brian also asked me how my old unit cooled each room. I had noticed there was a couple rooms that never seemed to be the same temperature as the rest of the house so they suggested and installed three more returns to remedy that. I also had them clean all my ducts while they were there.

I was eligible for a $1,200 rebate from Oncor and I got a nice thermostat which is like a tablet on the wall. I can monitor and change settings from my smart phone no matter where I am.

I am very pleased with the service I received and they made sure I understood my unit, how to operate it and my warranties. They also gave me a year free services to keep my system working properly for the next 2 to 3 decades.

Had these guys come out and look at my system yesterday. I have to say it was one of the most pleasurable service calls I've experienced in a goo d while. Fixed my issues, were thorough and didn't try to charge me for unnecessary repairs. This company definitely deserves, and earns your business. Give them a call!

Had them out to repair a furnace that wasn't working. They fixed the issue quickly. During the repair they noticed an unrelated component that wasn't functioning at 100% but also wasn't broken. They didn't try to force me into making additional repairs that weren't needed at this point. I'll definitely use them again!

Leonard is AMAZING.... great service, great personality and went the extra mile... Keller Services was timely in getting us scheduled... HIGHLY recommend and a high five to Leonard for getting us fixed up

We first used them back in 2016. Brian came out the day that I called, and thank goodness as it was cold! My husband thought so much of him and his honesty that he gave him an extra 25 dollars. I don't want to be upsold and some of those companies technicians are paid a commission and do just that! Brian was not like that. Very knowledgeable!! Well we have continued to use them, in fact here recently when my AC wasn't cooling, he offered to come on Sunday, and I just had them wait until Monday. Once again, he was fair, and in and out in no time. Happy we found a company we can trust.

My service technician was Alan Ross. He was very knowledgeable, professional, and very honest. I highly recommend Alan Ross and Keller Services to anyone and everyone.
Best company ever!!

Briar Choate was very professional and super helpful, he fixed the issue in less than an hour, check everything, wearing different shoes and a mask to enter the house. We are very pleased with the Keller Services Company and we will use them for future services.
