AC Repair FAQ

Get answers to common questions about our professional air conditioning repair services in Thornhill and the Greater Toronto Area

Serving Thornhill & GTA
01

What are common signs my AC needs repair?

Common signs include weak airflow, warm air blowing, unusual noises (grinding, squealing), strange odors, frequent cycling, high humidity indoors, water leaks, or significantly higher energy bills.
02

Do you offer emergency AC repair?

Yes! We provide 24/7 emergency AC repair services throughout Thornhill and the GTA during cooling season. No AC during a heatwave is an emergency, and we prioritize these calls with fast response times.
03

What AC brands do you repair?

We repair all major AC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Bryant, American Standard, and more. Our technicians are trained on multiple brands and carry common parts.
04

How much does AC repair cost?

Repair costs vary based on the issue, parts needed, and system type. We provide upfront pricing before any work begins with no hidden fees. Diagnostic fees may apply but are often waived if you proceed with repair.
05

Should I repair or replace my AC?

Consider replacement if your AC is over 10-15 years old, requires frequent repairs, or repair costs exceed 50% of a new unit's price. Our technicians will provide honest recommendations based on your situation.
06

Do your AC repairs come with a warranty?

Yes! All our AC repairs come with a warranty on both parts and labor. Warranty periods vary by repair type and parts used. We stand behind our work and will fix any covered issues at no additional cost.
07

How can I prevent AC problems?

Annual AC maintenance is the best prevention. Regular tune-ups improve efficiency, extend system life, and catch small issues before they become expensive repairs. We recommend scheduling maintenance every spring before cooling season.
08

What should I do if my AC stops working?

First, check your thermostat settings and ensure the AC switch is on. Check your circuit breaker and replace the air filter if dirty. If these don't resolve the issue, contact us immediately for professional diagnosis and repair.
