What does a $79 air conditioner tune-up actually include?

Cleaning and inspecting the outdoor condenser coil, checking refrigerant pressures against the manufacturer’s specification, inspecting and tightening electrical connections, testing the contactor and capacitor, confirming the condensate drain is clear, and verifying the system reaches its expected temperature split across the indoor coil. If we find a fault beyond the tune-up scope, you get a price for it and you decide — the tune-up is not a door-opener that grows on the invoice.

Why is my air conditioner running but not cooling?

The most frequent causes are a clogged air filter or blocked return starving airflow, a dirty outdoor coil that cannot reject heat, a failed capacitor leaving the compressor humming but not starting, low refrigerant from a leak, or a frozen indoor coil. Start by checking the filter and making sure the outdoor unit is clear of debris and plants. If those are fine, it needs a diagnostic.

Why is ice forming on my air conditioner?

Ice on the indoor coil or refrigerant line almost always means either restricted airflow or low refrigerant charge. Turn the cooling off, set the fan to ON to thaw the coil, and replace the filter. If it re-freezes after thawing, there is a refrigerant or airflow fault that needs measuring instruments to diagnose. Running a frozen system risks liquid refrigerant reaching the compressor, which is the expensive failure.

Should I repair or replace my air conditioner?

Central air conditioners typically last 12–15 years. Under about 10 years, repair is usually the better economics. Past 12 years, a major failure such as the compressor or a refrigerant leak in the coil often makes replacement the cheaper option over the remaining life, and a modern high-SEER unit meaningfully cuts summer operating cost compared with a unit from the mid-2000s.

How often should an air conditioner be serviced?

Once a year, ideally in spring before the first stretch of real heat. Most manufacturers require documented annual maintenance to keep the parts warranty valid. Annual service also catches the cheap failures — a weak capacitor, a dirty coil, a partially blocked condensate drain — before they become a no-cool call during a heat wave when every contractor in Durham Region is booked solid.

Does my older air conditioner still use R-22 refrigerant, and does that matter?

If your system dates from roughly the mid-2000s or earlier it may use R-22, which has been phased out of production. Servicing an R-22 system is still possible but the refrigerant is scarce and expensive, so a significant leak on an R-22 unit usually tips the decision toward replacement rather than repeated top-ups. A technician can confirm from the rating plate on the outdoor unit.

Can I get same-day air conditioner repair in Durham Region?

Same-day service is available subject to technician availability, and we run 24/7 emergency support for no-cool failures. Booking hours are Monday to Saturday, 8:00 am to 8:00 pm. During heat waves, call as early in the day as possible — that is when the day’s remaining slots are still open.

How can I reduce my air conditioning costs without replacing the system?

Change the filter on schedule, keep at least 60 cm clear around the outdoor unit, close blinds on sun-facing windows during the day, use ceiling fans to raise the temperature at which you feel comfortable, and have the coil cleaned annually. A dirty condenser coil is one of the largest and most commonly ignored efficiency losses in a residential system.
