"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Mr. Hollister was great! I was really impressed with his promptness, quality of work and friendliness. The plumbing was the smoothest process for our 2nd floor addition project. Thank you Mr. Hollister for your great work, patience and flexibility! I would hire him again."

"Can't say enough good things about Whalen Plumbing and Heating. Our tankless water heater was giving us inconsistent temperatures and error codes, and they made the fix painless. They showed up on time, asked what we'd noticed before touching anything, and clearly know these units inside and out. They flushed and descaled the heat exchanger, cleaned the inlet filter, and checked the venting and connections, explaining everything in plain English with no pressure to upsell. They were respectful of our home and left the area cleaner than they found it. Pricing was fair and matched the quote exactly. Since the visit, our hot water has been steady and the unit runs quieter than it has in a long time."

"My water heater died (leaked) late Wednesday nite. Thursday I called numerous plumbers-left messages, Burke's called back and by Friday afternoon I had a new water heater installed. I am in a mobile home and some plumbers said they don't service mobile homes."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."
