What We Do

Our Services

Air Conditioner

AC is a must-have to get through Toronto summers comfortably! AccuServ technicians are ready to help you fix, service, or replace your AC unit in as fast as yesterday.

Tankless Water Heater

Tankless Water Heaters are the 21st century ticket to unlimited hot water, compact, space saver units and long-lasting tanks. AccuServ specializes in tankless water heater repair, maintenance and installation.

General Contracting

At AccuServ, we love working with renovation contractors to transform older Toronto houses into modern, heat efficient luxuries.


Surviving winter in Toronto is tough enough with a fully functioning boiler system, but when it starts making weird sounds, or smells gassy, or burns red instead of blue, get in touch with AccuServ. Our technicians will come quickly to the rescue.


Cold and windy days are best spent snuggled up in front of the fireplace with a cup of hot cocoa and a good book. But when the switch to light your fire doesn’t work, or smells funny, AccuServ can help figure out what’s wrong and fix it in a jiffy.


Not having a proper ductwork system can lead to unhealthy air circulating throughout your house, higher energy bills and an overworked HVAC system. AccuServ technicians repair and install ductwork that transforms the feel of the air within your home and helps eliminate drafts, leaky air and high energy bills.

Tank Water Heater

Most older Toronto homes have tank water heaters. AccuServ technicians are well versed in water tank inspections, troubleshooting, and replacement.


Ice storms, blizzards, and terrifying gusts of wind, Toronto winters are not to be lived in without an efficient furnace. AccuServ is here to rescue you from the winter cold before it gets into your bones.

For over 30 years and counting, we pride ourselves in going the extra mile to serve our customers.
