Ontario customers on our AC tune-up

★★★★★

Installed a ductless mini split in our garage conversion. Neat work, quiet unit, and they walked us through the remote and app. Very happy.

Patricia H., Ontario
★★★★★

The technician was on time, wore shoe covers, showed me the failed part and explained the repair versus replace math. Fair price and no pressure.

Susan K., Ontario
★★★★★

Furnace kept shutting off every few minutes. They found a dirty flame sensor and a clogged filter, cleaned both, and it has run perfectly since. Quick and affordable AC tune-up.

AC Tune-Up in Ontario: frequently asked questions

When is the best time for an AC tune-up?

March through May, before the first heat wave reaches Ontario. Fall is the second-best time, right after the cooling season ends.

Does a tune-up include repairs?

The tune-up includes cleaning, testing and adjustment. If we find a failing part we show it to you and quote the repair before doing anything extra.

Is annual maintenance really necessary?

Most manufacturers require it to keep the parts warranty valid, and it typically pays for itself in energy savings and avoided repairs.
