Would Have Him Come Back Again
Had a plumber come out to the house within an hour of calling to make an appointment. A fix was done on an outdoor faucet. It included some inside work that added a shutoff valve to be used in the winter. Mel answered all of my questions. The job was done in an efficient amount of time. The repair was pricey, but may have prevented a future leak. Would have him come back again for future plumbing issues.
An Excellent Experience with BW Cook
I, as a former HVAC professional, had an excellent experience with BW Cook ¹û¶³´«Ã½. The technicians arrived on time, were honest, professional, and courteous, and clearly explained the issue and repair. Everything was fixed quickly and has worked perfectly since.
Their honesty and fair pricing really stood out—no surprise charges or pressure to buy unnecessary services. It’s refreshing to find a company that takes pride in quality work and customer care.
I highly recommend them for reliable, knowledgeable, and trustworthy service, and I’ll definitely use them again.
I would recommend them hands down
Our 19-year-old GEO heat pump went out, called around, and to replace it was way too much, so we decided to go for a conventional HVAC system. Looked around, but no other place does leasing until we found BW Cook. Service techs that came to install our unit was done in 1 day, and we were back into our nice cold house again! I would recommend them hands down!
Very Friendly and Communicative

We have had great experiences with BW Cook — we needed a new toilet installed due to a bad clog and Derrick came out quickly to help us.
