"Very grateful for such an easy and pleasant experience when I suddenly found my very old hot water heater leaking all over the basement floor on a Sunday evening. I did a quick panicked search and thankfully Arctic answered my call and put me at ease with a quote for a replacement and an install appt for first call the next morning. Adam K arrived on time, was very sweet & professional, and installed our new unit in under an hour. Will definitely use Arctic again!"

"This morning we found out our water heater broke and Good Tiddings responses to our request within ten minutes. Anthony was very responsive and got someone to our house within two hours. Brian was helpful and did a great job getting everything fixed. They gave us a few instructions on future maintenance so our new water heater will remain functional. Everything was resolved within a few hours. We will definitely use their services again!"

"Outstanding service, start to finish. Professional, courteous, constant communication. Isha from the home office was in constant contact - phone, two email confirmations, and texts. She called to ask if the service could start a bit earlier, which was fine with me. Alex arrived promptly, put on shoe booties before entering the house (not necessary here but a nice touch). Alex was outstanding. Young fellow with many years experience, and it showed. He explained each part of the task as he went through it, and answered my many questions related to other potential work I brought up. Getting the anodes out of the water heaters - first time replaced - was a bear. He explained he had to get another socket wrench to loosen the anodes - the ones he had did not fit properly. No charge for that time, which though I expected, has not always been the case in my past experiences. Anodes were locked in tight, and took a while to loosen. Doing one water heater at a time, they finally came out, encased in calcium deposit. He then screwed in the replacement anodes and locked them in. Alex completed all the work, put everything back together including the fans on top of the units, tested, and re-tested. Continuing to explain each step. He took pictures of the work for the invoice, ran me through the details again. Everything done on his tablet computer; I received an immediate email receipt. Excellent work with knowledge behind it. I have an external faucet which needs repair, and may be looking for a whole-house water softener. When time comes to replace the water heaters, Advanced Pro will be at top of my list."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."
