Choosing a new heating and cooling system is neither easy nor inexpensive. There is a bewildering array of options, and the technology of modern units is complicated and requires installers and maintenance technicians that are highly trained and kept abreast of technological changes. After speaking with three heating/AC companies in St Catharines, we felt most confident that Service Experts had the product, reputation, knowledge and proficiency to best meet our needs and contracted to have them install a new high-efficiency furnace, AC and continuous hot water heater. From beginning to end, we were totally satisfied with the all aspects of the project. Beginning with the sales agent that met with us, Tom, who patiently explained our options and simplified the mechanics so we could make informed comparisons and understand the pros and cons of different units, we experienced only professionalism of the highest order. After working with us to arrange a convenient installation time, the two installers, Brian and Shane arrived promptly and worked efficiently and collaboratively (between them, they had more than 60 years of heating and cooling installation experience) to expertly install all units in two days. I was particularly struck by the care and expertise that went into every phase of the installation. Even to my untrained eye, the adaptation of the duct work (they were replacing a 41-year-old furnace about three times the size of the new unit), the soldering of copper lines and fittings, and the installation of vent pipes was exceptional. And as promised, the furnace room and surroundings were left cleaner than when they arrived. And everyone at SE made one thing clear – they stand behind their product. Based on our experience, I highly recommend Service Experts. I also suggest that if you factor in all the variables, from initial quality of product to expertise of installation to continuing service, SE is very competitive in cost as well.
