Answers about same-day wall-mounted AC cleaning, mini-splits, heat pumps, pricing, and booking—plus our guides for odours, leaks, and what is included.

Frequently Asked Questions

Last updated - June 16, 2025

What exactly does your AC cleaning service include?
We perform a six-step deep clean: pre-vacuuming, coil wash, filter cleaning/replacement, drain-pan flush, non-toxic disinfection, and final airflow/temperature testing. You get before & after readings plus a short report.

Are your technicians certified and insured?
Yes—every Climéo tech is factory-trained in HVAC cleaning, carries full liability insurance, and uses only Health Canada–approved products.

How much does AC cleaning cost in Montreal?
Use the pricing page for flat residential rates before taxes (Island travel included). Commercial and multi-head systems are itemized in the same grid.

What does mini-split cleaning cost?
Additional indoor heads are priced per head on pricing; compare the multi-head column before you book.

My wall-mounted AC smells musty—could it be mold?
Odours usually mean moisture and biofilm in the coil or drain path. Read the musty wall-unit guide and book if water or smell persists after filter checks.

My wall-mounted AC is leaking water—what should I do?
Switch cooling off if water threatens finishes, then review the leaking wall-unit guide while you wait for service.

How often should a heat pump be cleaned?
Annual for most homes; semi-annual when the same head runs hard in both heating and cooling or with pets/allergies. See also heat pump service detail.

RESIDENTIAL CLEANING

Last updated - June 10, 2025

How often should I clean my home AC?
We recommend an annual cleaning for most homes. If you have pets, allergies, or heavy year-round heat-pump use, consider a semi-annual service.

Do I need to be home during the cleaning?
Ideally yes, but not mandatory. If you can provide access (e.g., leave a gate code), our team will text you when they arrive and again when they finish.

COMMERCIAL SERVICES

Last updated - June 8, 2025

Do you clean large rooftop or packaged units?
Absolutely. We handle everything from small office wall units up to multi-ton rooftop condensers. Commercial quotes are provided after a quick on-site assessment.

Can you work outside business hours?
Yes—early mornings, evenings or weekends. Just select “After-hours” in our booking form or call us to arrange the time that minimizes your disruption.

AUTOMOTIVE AC

Last updated - June 10, 2025

How does car AC cleaning differ from home systems?
We use a portable fogger to disinfect the vehicle’s evaporator coil and ductwork, plus replace the cabin air filter. It’s a quick, 30-minute treatment that removes odors and bacteria.

Do you come to my home or office to clean my car?
Yes—we offer mobile car-AC service within the Greater Montréal area. Just park your vehicle in an accessible spot and we’ll handle the rest.
