"Steve, is very professional and did a great job fixing the gas fireplace."

"Top notch professionals…they were the only company that used a camera to inspect the chimney and didn’t try to sell me anything I didn’t need. Highly recommended"

"Okay except for two things: (1) The cleaning only addressed the duct from outside; they refused to check the dryer duct hose from inside. We did not discuss this ahead of time because I assumed that was part of their service. (2) In addition to the $125 to clean the duct, they also charged me $110 for a metal cover to fit over the opening of the duct outside. When I asked them to identify this item so I could compare it with other similar covers, they said they couldn't do that. They said the high cost reflected a charge for removal of the old cover and installation of the new cover to the outside vent opening. When I asked why attaching the cover was so expensive, they compared the cost to what a car garage would charge to change your oil."

"Walter is awesome. He did a proper job of cleaning our chimney and even helped us out with a pesky gas log configuration and burner advice. He goes above and beyond! Highly recommended!"

"I hired A&S to replace damaged refractory panels in my pre-fab fireplace. They gave me an estimate based on photos, scheduled an appointment, and completed the work on time as contracted with no issues. The workers were on time, professional, and personable."

"We called to have our chimneys inspected because we had a bat in our home. Tim inspected both chimneys and the roof. He removed the caps and installed stainless steel screens over the flue opening on both fireplaces to help prevent bat intrusion through the flue. He did an excellent job. During his inspection, Tim noticed a hole in the b-vent chimney. Tim installed a new b-vent chimney from the basement to the roof. He connected it to the water heater and the furnace. There was no damage to our drywall which he had explained was a possibility during installation. They did an excellent job of cleaning up the debris and removing the existing pipe. We would highly recommend Top Shelf Chimneys."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Rob O'Donnell came in clutch for us when we found ourselves in a pinch doing a job out of our normal service area for a customer who had water damage to their home. It was after 4:00pm on a Friday afternoon and we needed to find someone to disconnect a gas stove so we could finish installation on Saturday. Needless to say, we were having trouble finding anyone who could help us out with such short notice. After leaving a message with O'Donnell's Plumbing we got a call shortly thereafter from Rob, who was willing to go out on Saturday morning to disconnect the gas line for us before another job he already had scheduled for the day. He also returned very promptly to get everything hooked back up. -- furthermore he was able to send an invoice by email and we were able to pay electronically! Very convenient and also eliminated the need to bother with mailing a check. -- Highly recommend O'Donnell's Plumbing!"
