Frequently Asked AC Questions (Install, Repair & Maintenance)

Central air conditioner installations in Sarnia and Lambton County typically range from $5,500 to $12,000+, depending on equipment efficiency, size, ductwork condition, and electrical requirements.
Proper sizing depends on square footage, insulation, window quality, exposure to sun, and duct design. We complete a load calculation to avoid units that are oversized (short cycling) or undersized (constant running).
Higher-efficiency units cost more upfront but can reduce cooling energy use by 15–30%, especially in homes with long cooling seasons or higher hydro rates. We match SEER/SEER2 levels to your budget and usage.
Most AC repairs fall between $200 and $1,200+. Costs depend on whether the issue involves sensors, capacitors, motors, refrigerant leaks, or control boards. We provide diagnostics and upfront pricing before work begins.
Common causes include dirty coils, clogged filters, low refrigerant, failing fan motors, undersized ductwork, or thermostat issues. A diagnostic visit identifies the root cause so repairs are targeted and effective.
Yes. We provide same-day and emergency AC repair across Sarnia, Point Edward, Bright’s Grove, Corunna, Lambton Shores, and surrounding areas. No-cooling situations during heat waves receive priority dispatch.
Replacement is usually recommended when the unit is over 12–15 years old, uses R-22 refrigerant, has repeated failures, or when a major repair approaches 30–40% of the cost of a new system.
We recommend a professional AC tune-up once per year, ideally in spring before peak summer loads. This keeps efficiency high and reduces the chance of mid-season breakdowns.
Maintenance includes coil cleaning, checking refrigerant pressures, testing electrical components, inspecting the condensate drain, verifying thermostat operation, and confirming proper temperature drop across the coil.
Most central AC systems last around 12–18 years with annual maintenance. Well-maintained units tend to have fewer repairs and more stable efficiency over time.
Yes. Our WeCare maintenance plans include annual AC tune-ups, priority service in peak season, and discounts on air conditioner repairs. Plans are available for central AC, ductless systems, and heat pumps.
