customer testimonials
Here are some of the reviews we have received from property owners just like you.
It is unusual to get good customer service any more. Called Klein Heating and cooling about an AC system draining out of the emergency drain and within 1/2 hour their technician was at my residence.
He was professional, knowledgeable and courteous. He diagnosed the problem, and made the necessary repair. It is refreshing to find a business that emphasizes customer service and satisfaction.

I am quite pleased with their work and will not hesitate to recommend them.
I used their service a few years back and was very happy with the job done then. So no hesitation to call them back when there was a small leak on the pipe right above the furnace.
One plumber came and inspected the area, explained the situation and gave me a couple recommendations.
The team came shortly after he left. The work area was very tight and yet the team did a good job. They were professional and very efficient, just like the last time.

Incredible service from the moment they walk in your door until you're feeling the cold air of your AC once again.
Their techs are incredibly professional and they go out of their way to contact you before they arrive at your home. They also introduce you to the tech who will be servicing you that day.
If any else has an experience like I did, you will feel confident that you're getting the best and most HONEST service required to get your AC up and running again. They come highly recommended.

Klein Heating and cooling installed an AC unit in our bedroom in 2021 just before the hot summer. The installer was very professional and worked clean and tidy.
The entire process from the first phone call to the last email/ phone call was smooth and no problems. We are very happy with our AC. If you ever decide to get a AC installed in your house.. Call this Company!

Excellent service as always. This is the second AC we have gotten from this company. We have always had great and fast service. Klein Heating and cooling technician was very pleasant, polite, professional and helpful.
He went above and beyond with his work. He answered our questions without sounding like we were a bother. I recommend this company for any AC needs.

Klein Heating and Cooling was amazing! Saved us a fortune. The awesome technician explained everything and really went the extra mile to make sure our AC was working.
We went from 89 degrees in our home back to normal in just a few hours. We asked them back to see about our duct work too! Couldn't recommend them enough!

After my water heater went out, I called my warranty and they arranged a service call with Klein Heating and cooling. Had a technician in my house within 3 days and a replacement water heater within 2 days.
I can’t say how grateful I am!! With the cold weather approaching, no more cold showers. Technicians were very professional and quick. The whole process was extremely fast from start to finish and very convenient.
Definitely making Klein Heating and cooling my service provider from now on.

Very prompt, professional and pleasant service at a competitive price. Yesterday afternoon we noticed that our hot water heater was not heating up the water.
We researched online and found Klein Heating and cooling to be best rated. Now we know why. We called them last night. After determining what we needed they explained their recommendation and made an appointment.
Tech came right on time this morning and now we have a new water heater. Would definitely recommend Klein Heating and cooling to our friends. Thanks!

We had no AC and they came right out on a Saturday. The service tech was extremely professional and wanted to help. He recommended some options and we decided to replace the entire system. Two days later five of the most enthusiastic and professional guys came over and got us an all new system.
The pricing in my research was average for the industry but the service was way above par. Thanks a lot for the great experience!! My house is freezing yay!

It was an amazing experience. They were prompt, professional, and honest. I had a very old AC system from 2010. While it was still functioning, it certainly was not efficient or quiet. Klein Heating and cooling provided a replacement.
Klein Heating and cooling tech team were informative about the process and quickly took the old system away. Thank you.

Keeping our AC system in the best possible shape is very important to us, so we signed up for the Maintenance Plus service and we have technicians come twice a year to make sure it is working properly.
We'll be staying with Klein Heating and cooling for as long as they can provide the quality and competitively-priced service we've come to expect!
