service and repair

LSM's service technicians can diagnose and repair many different residential furnace, air conditioner, garage heater, water heaters, and fireplace models.  We offer 24-hour service: after 5 pm, weekends or holidays, call 780-532-5210 to contact a technician on call. 


Planned Service is a regularly scheduled program of maintenance. Our technicians inspect, clean, adjust and lubricate your equipment to keep your system running at peak efficiency. Regular tune-ups can help lower your fuel bills and can often prevent breakdowns and repairs by spotting potential trouble early. It also provides proof of maintenance if you have to process a warranty claim. LSM Planned Service protects your peace of mind all year long.  Take a look at our Simple Maintenance Tips.

Duct Cleaning

Indoor air quality is important especially since we spend 6 months out of the year indoors sheltered from the cold. Make sure to schedule a furnace duct cleaning once or twice a year to improve your indoor air quality by having your furnace ducts cleaned by LSM's high power vacuum duct truck and professional duct cleaning crew. 

If you have a new home or have recently done renovations, LSM recommends getting your ducts cleaned to remove any sawdust or drywall dust from the ducts as that can be very hard on your furnace components.

indoor air quality

Today we spend over 90% of our time indoors. We can install filtration systems that can filter chemicals (off-gasing from building materials, fire retardants, etc.) and particulates (dust, pollen, mold spores, animal dander). Send an email to our Home Comfort Advisor or check our Indoor Air Quality Product Comparison page.

Ever wonder what that switch is above your thermostat?  In some new homes, they put the control to your air-to-air exchange (or principle exhaust) as a timer or switch above your thermostat.  Read more.
