I got no choice but to give Sean and crew top ratings. Came on a moments notice and replaced my hot water tank. A #1 job done very fast and at a good price. I’d recommend Avalon Plumbing to anyone.

Dani Burt - Virtual Shore

Sean and his team replaced my rusting hot water tank recently and did a fantastic job! They were fast and efficient, no leaks and no issues after installation. Sean gave me easy to follow instructions and was very clear on expectations. Highly recommend!

Karen Doyle

Excellent Service and Communication! I would highly recommend their services. Our hot water boiler died on us in the middle of a snow storm. My husband called Avalon Plumbing and Heating. They discussed every option with him thoroughly. They came the next day with a new boiler. They disconnected the old one and took it away for me. They had to take down a door to access the old tank. I didn't have to do a thing. They put the door back up and left the place just as clean (probably cleaner) than it was when they arrived. I will definitely use their services again!

William Mercer

I called Avalon Plumbing with a hot water issue and Sean responded immediately. He was able to schedule me in such a way that there was no real inconvenience. He removed the old water heater and installed a new one in short order. He was very professional in his work and presentation, taking time to explain what he was doing and also pointing out some issues that had gone on undetected. His friendly demeanor was a pleasant addition to the whole experience. I would highly recommend Avalon Plumbing and Heating to anyone who needed work done. I will be calling them again when the need arises.

Frequently Asked Questions

Does Avalon provide 24-hour emergency service?

Yes. Avalon offers 24-hour emergency service.

How long does a hot-water boiler installation take?

The installation process includes draining the boiler, removing the old tank and installing a new one, usually within an hour; Avalon carries a small boiler inventory in its vans.

What electrical supply is needed for an oil-to-electric furnace conversion?

An electrician must verify 100 amps at 240 volts for a 20 kW furnace or 125 amps at 240 volts for a 24 kW furnace, with a neutral wire. A permit is required for the government rebate program.

Does Avalon install electric hot-air furnaces?

No. It does not install electric hot-air furnaces; for a hot-air system, it recommends conversion to a heat pump and can remove the oil tank for that procedure.

Is financing available for oil-to-electric conversions?

Yes. Financing through NL Power is available for oil-to-electric conversions.
