All Heating & Cooling
AC repair diagnosed by mechanism, not by symptom alone
Warm air blowing from the vents can mean a dozen different things — a failed capacitor, low refrigerant, a frozen coil, or a wiring fault. We test to find out which one before recommending a repair.

Why AC failures cluster in July and August
Air conditioners in the GTA sit idle for eight or nine months a year, then get asked to run continuously through the hottest, most humid stretch of summer. Components that were marginal in June often fail outright once the compressor is under sustained load.
Capacitor degradation
Run and start capacitors weaken with age and heat exposure, and often fail exactly when demand — and outdoor temperature — peaks.
Refrigerant charge loss
A slow leak that was tolerable in cooler weather becomes an obvious performance problem once cooling load increases in peak summer.
Coil icing
Restricted airflow from a dirty filter or low refrigerant causes the evaporator coil to freeze, which then cuts cooling entirely until it thaws.
Electrical connection wear
Contactors and wiring connections loosen over years of thermal cycling, causing intermittent operation or full failure to start.
A system that 'runs but doesn't cool' has a specific cause
This is one of the most common calls we get in a GTA summer: the outdoor unit is running, air is coming from the vents, but the home isn't cooling down. Homeowners often assume this means the refrigerant needs a top-up, but that's only one of several possible causes — restricted airflow, a failing compressor, or a duct issue can produce the identical symptom.
We test airflow, pressures, and electrical draw together
Rather than guessing based on the symptom alone, we measure supply and return air temperature, check refrigerant pressures against the manufacturer's chart, and test electrical draw at the compressor. That combination tells us the actual failure point, so the repair addresses the cause rather than masking it temporarily.
Our AC repair process
Every repair call follows the same diagnostic sequence.
- 1
Email your issue
Describe what the system is doing — or not doing — and we'll schedule a visit, prioritizing no-cool calls.
- 2
On-site diagnostics
We test electrical components, refrigerant pressures, and airflow to isolate the actual failure.
- 3
Explain the finding
You get a plain-language explanation of what failed and why, before any repair work begins.
- 4
Repair performed
Parts are replaced or repaired using manufacturer-correct components matched to your system.
- 5
Verified operation
We confirm proper cooling output and correct pressures before considering the job finished.
Why homeowners contact us for AC repair
A repair that doesn't address the actual cause tends to fail again within weeks.
Root-cause diagnostics
We test the system rather than replace parts on a guess.
Licensed refrigerant handling
All refrigerant work is performed by properly certified technicians.
Priority for no-cool calls
We understand what a failed AC means during a heat event.
Straightforward pricing
You know the diagnosis and scope before repair work starts.
Manufacturer-correct parts
Replacement components are matched to your system's specifications.
Efficiency-aware repairs
We flag when a repair is no longer the efficient choice versus replacement.
AC repair questions
My AC is running but not cooling — what's wrong?
This can be caused by low refrigerant, restricted airflow, a frozen coil, or a failing compressor. We test each of these to identify the actual cause.
Why does my AC only run for a few minutes at a time?
Short cycling is often caused by an oversized unit, a failing capacitor, or a refrigerant issue. We diagnose which before recommending a fix.
Is it worth repairing an older AC unit?
It depends on the age, the specific failure, and repair cost relative to replacement. We give you a straight comparison rather than defaulting to either option.
How quickly can you respond to a no-cool call?
We prioritize no-cool calls, especially during heat events, and aim to schedule these as quickly as our schedule allows.
Do you repair all AC brands?
We service most major residential brands installed across the GTA.
