Michael Did a Great Job
Michael did a great job today keeping our system running smoothly. Happy to be Advantage customers!
Very professional and very pleasant
Have a great service man, Rollie. Very professional and very pleasant, and I feel very confident knowing my furnace and my air conditioner are both in top shape.
On time and very informative
The guys were on time and very informative about the system and the needs for the house.
They were friendly and professional
Rollie and Kody from BW COOK just performed a regular maintenance call to service our air conditioner. They were friendly and professional in every way. They evaluated what was needed and got everything done with no hassles and in a timely fashion. Our AC works beautifully thanks to their regular inspections.
Very Surprised to Have Same-Day Service
As a new customer calling in late afternoon on a Friday, I was very surprised to have service that very same day. My service technician, Hunter, was very knowledgeable, diagnosed the issue right away, explained everything, and in no time the A/C was back up and working. Thank you, Hunter and BW Cook Service Experts.
Very thorough and professional
Robert encountered a perplexing problem but stuck with it and eventually located the problem. He was very thorough and professional.

Thanks, Erik T, for a great job. Very helpful and courteous.
Very knowledgeable and professional
The technicians were very knowledgeable and professional. They are welcome any time!
Great job and service!
Denis just finished putting my grandparents' new AC unit in, and I wanted to thank him for his work. He was nice, answered our questions, and worked endlessly in this heat. Great job and service!
The young man was excellent
The young man that put in my water heater was excellent. He was here when he said he would. He worked very hard all day. Thank you.
Very, very nice people
Needed our A/C replaced. During their inspection, they found our furnace would have killed us via spewing carbon monoxide if we used it this winter, and also noticed our water heater had a constant drip, so it was busted. Had a triple threat on our hands... usually dreadful, but after we were approved (not-so-great credit, so 3rd party approved), they had it installed and thoroughly went through all the details with us. Very, very nice people and a very quick installation! Thanks for saving us from dying from heat stroke this summer and carbon monoxide poisoning this winter!
Fantastic experience!
Fantastic experience! Great work! Derick did a great job installing the tankless water heater! Highly recommend!
So kind and knowledgeable
John & Cody helped us. They were so kind and knowledgeable. Would definitely recommend!
Highly recommend!
Went to shower and had no hot water. Someone was able to troubleshoot and diagnose less than two hours later. Scheduling was easy and communication was great. Was able to get the part in quickly and be back up and running. Highly recommend!
They Have Both Been Amazing
I have had two plumbers out from BW/Cook and they have both been amazing. They are professional and knowledgeable. Highly recommend.
Everyone Was Great from Start to Finish
Everyone was great from start to finish. Denis came out to see what all would need to be done. Cheyenne came out to give pricing and helped us for two days so we could get furnace and central air installed. Denis and Sam came out on Thursday (May 14th) and started taking out the old furnace and started the process of relocating furnace to laundry room. Friday Denis was back out with the help of Kevin to rerun water lines and gas lines (which was no easy task) and then on Monday Kevin and Sam (there was another gentleman but we don’t know his name—wished I did or I would mention him too) were back out here all day to finish it all up (only thing left is exhaust for furnace). They did communicate well with us through everything! We appreciate you all!
Outstanding service
I am a member of their Advantage Plan. Just had preventative maintenance for my AC and furnace. Outstanding service. Service techs are professional. Highly recommended.
Very professional
Nice young man did a wonderful job. Very professional.
Incredibly young men worked tirelessly

Pleasant, Courteous, Knowledgeable, Efficient
Thirty-plus years of using BWCook for our HVAC needs (and, in recent years, our plumbing needs), and again, as always, they were pleasant, courteous, knowledgeable, and efficient. ["They" includes the phone people as well as the in-home technician.]
