Professional Air Conditioning Repair in Toronto

Fast, Reliable AC Repair When You Need It Most

There's nothing worse than an air conditioner that stops working on a hot summer day. When temperatures climb and your home becomes uncomfortable, you need a repair service you can count on to respond quickly and get the job done right.

At Northfield Heating & Cooling, we've been keeping Toronto homes cool for over 25 years. Our team of licensed technicians has the training and experience to diagnose and repair all types of air conditioning systems, from central air units to ductless mini-splits and heat pumps.

Common AC Problems We Fix

Air conditioning systems can fail for many reasons. Some of the most common issues we see in Toronto homes include:

• AC not turning on – Could be an electrical issue, thermostat problem, or failed capacitor
• Not cooling properly – Often caused by low refrigerant, dirty coils, or airflow restrictions
• Strange noises – Grinding, squealing, or banging sounds indicate mechanical problems
• Water leaks – Usually a clogged condensate drain or frozen evaporator coil
• Short cycling – System turns on and off frequently, indicating sizing or component issues
• High energy bills – An inefficient system working too hard to cool your home

No matter what's causing your AC problems, our technicians will diagnose the issue accurately and explain your repair options in plain language. We believe in honest communication, so you'll always understand what needs to be fixed and why before we start any work.

When to Repair vs. Replace

Sometimes repair makes sense; other times, replacement is the better investment. We'll give you honest advice based on:

• Age of your system (most AC units last 15-20 years)
• Cost of repair vs. replacement
• Energy efficiency of your current system
• Frequency of recent repairs
• Availability of replacement parts

We never push unnecessary replacements. If a repair will get you several more years of reliable cooling, we'll tell you.
