Central Air Conditioners

All new AC units now use low-GWP R-32 refrigerant. The choice is staging: single-stage cools in one gear, while two-stage and inverter units run longer on low for better humidity control, quieter operation, and lower bills.

Runs mostly on low stage, so it removes more humidity and runs quieter than a single-stage unit — the difference between "cold" and "comfortable" on a muggy July afternoon. The popular middle pick.

Efficiency: Up to 17 SEER2
Compressor: Two-stage
Refrigerant: R-32 (low-GWP)
Comfort: Longer low-stage runs pull more humidity, quieter

When the AC quits in the middle of an Ontario heat wave, you want two things: a straight answer on what's wrong, and a price before anyone starts pulling it apart. That's how we work. We diagnose first, tell you what the fault is and what it costs to fix, and you decide before we lift a wrench. No work, no charge beyond the diagnostic.

We run 24/7 and service every type of air conditioner — central air, ductless mini-splits, and window units — from all the major brands. Our trucks carry the common parts, so a capacitor, contactor, or motor swap is often done in a single visit. In summer we prioritize no-cooling calls and aim for same-day where we can. Call (647) 491-6009 any time, day or night.

Common AC Problems — and What's Usually Behind Them

Most cooling faults trace back to a short list of causes. Here's what each symptom tends to mean before we've looked.

Blowing warm air / not cooling

Usually low refrigerant from a leak, a dirty condenser coil, or a failed capacitor or contactor stopping the compressor from starting. A frozen evaporator coil will do it too.

Water around the indoor unit

Most often a clogged condensate drain backing up into the pan. Sometimes a frozen coil thawing, a cracked pan, or a stuck float switch shutting the system off.

Strange noises or smells

Grinding or screeching points to a motor or bearing; buzzing to an electrical fault; a musty smell to mould in the coil or ducts. None of these get better on their own.

Short cycling

The AC starts, runs a minute or two, and shuts off again. Often a low charge, a failing capacitor, a dirty coil, or an oversized unit — hard on the compressor either way.

Ice on the coil or lines

Ice means airflow or charge is off — a clogged filter, a weak blower, or low refrigerant. Running it iced up risks the compressor, so shut it off and let it thaw first.

Won't turn on at all

A tripped breaker, a dead thermostat, a blown capacitor, or a failed contactor. We check the simple things first before reaching for anything that costs real money.

Before you call: a few things to check

Some no-cooling calls turn out to be small things you can check in two minutes. None of these are risky, and any one of them might save you a service visit:

·Set the thermostat to cool and a few degrees below the room temperature. If it takes batteries, swap them.
·Check the breaker for the AC. If it has tripped, switch it fully off and back on once. If it trips again, stop and call — that's a fault, not a fluke.
·Look at the filter. A clogged filter starves the system of airflow and can ice the coil. If it's grey and matted, replace it.
·If the indoor coil or copper lines are iced up, turn the AC off but leave the fan on to let it thaw. Running it frozen can wreck the compressor.

If you've been through these and the AC still won't cool, it needs a technician — and that's where we come in.

The honest part: refrigerant and the compressor

Two repairs are worth flagging before you spend money, because they often change the answer from fix it to replace it.

An R-22 leak. If your AC runs on R-22 refrigerant — common on units roughly twelve years and older — and it's low, there's a leak. R-22 has been phased out and is no longer made, so recharging one has gotten expensive and only gets worse each year. Pouring money into a leaking R-22 system to keep an old, inefficient unit going is usually the wrong call; that money goes further toward a new system. Newer R-410A units are still serviceable, though that refrigerant is now being phased down as well, and 2026 systems have moved to R-32 and R-454B.

A compressor failure on an old unit. The compressor is the heart and the most expensive single part of the system. On a unit near the end of its life, a failed compressor usually means replace, not repair — the cost gets close enough to a new system that fixing the old one rarely makes sense. On a younger unit, plenty of smaller faults — a capacitor, a contactor, a fan motor, a clogged drain — are common and well worth repairing. We'll tell you straight which side of that line yours is on.

AC Repair — Real Work

When a Repair Isn't Worth It

If you're replacing anyway, price a heat pump first

Once an AC is past about a dozen years and facing a big repair — an R-22 leak or a dead compressor — the repair stops being the cheap option. That's the moment worth a second look, because replacing the AC is also the natural point to compare an air-source heat pump.

A heat pump cools your home in summer exactly like an air conditioner, and adds efficient heating through most of the year on top. The part that changes the math: a plain AC earns no rebate, but a qualifying cold-climate heat pump can earn up to $7,500 through Ontario's Home Renovation Savings Program — so after the rebate it can land close to the cost of a like-for-like AC while doing more. We confirm what your home qualifies for, lay the numbers side by side, and you decide.

Frequently Asked Questions

A few things cause this. The most common is low refrigerant from a leak — your system does not "use up" refrigerant, so if it is low there is a leak that needs finding and fixing, not just a top-up. Other causes are a dirty condenser coil that cannot shed heat, a failed capacitor or contactor that stops the compressor starting, or a frozen evaporator coil choking off airflow. Before you call, check that the thermostat is set to "cool" and below room temperature, and that the filter is not filthy. If those are fine, it needs a technician — we diagnose the exact cause and price the fix before doing any work.

Start with the easy things. Check that the breaker for the AC has not tripped (flip it fully off, then on). Check the thermostat is set to "cool" and a few degrees below the room temperature, and swap the thermostat batteries if it takes them. Look at the outdoor disconnect box near the unit to make sure it is seated. If all of that is fine and nothing happens, the usual culprits are a blown capacitor, a failed contactor, or a control-board fault — those need a technician. Call (647) 491-6009 and we will come out.

Ice on the indoor coil or the copper lines always comes back to one of two things: not enough airflow over the coil, or not enough refrigerant. Low airflow is usually a clogged filter or a weak blower; low refrigerant means a leak. The fix in the moment is to turn the AC off at the thermostat but leave the fan set to "on" so it can thaw — running a frozen system risks slugging liquid back to the compressor and wrecking it. Once it has thawed (give it a few hours), we can find why it iced up in the first place. Do not chip at the ice.

We charge a flat diagnostic fee to come out, find the fault, and give you a firm price — and we tell you that number before we book the visit, so there is no surprise at the door. Once we have diagnosed it, you get the repair price upfront and decide before we start. If you go ahead with us, the diagnostic is rolled into the job on most repairs. We will confirm the exact fee for your area when you call.

It depends entirely on the fault. Common repairs like a capacitor or contactor are at the lower end; a refrigerant leak repair and recharge, a blower motor, or a compressor sit much higher. The honest part is that a big repair on an old unit — especially anything involving R-22 refrigerant or the compressor — is often money better put toward a replacement. We diagnose first, give you the repair price upfront, and tell you plainly when a fix is worth it and when it is not. No work happens without your say-so.

Mechanically, yes — but it is usually the clearest case for replacing instead. R-22 refrigerant has been phased out and is no longer produced, so the price to recharge a leaking R-22 system has climbed sharply and keeps climbing. If your R-22 unit has a leak or a failed compressor, you can spend a lot to keep an old, inefficient system limping along, or put that money toward a new unit that costs far less to run. We will tell you straight which makes sense. Newer R-410A systems are still serviceable, though that refrigerant is now being phased down too.

Air conditioners last about 12 to 15 years here. A rough rule: if the unit is under about 10 years old and the repair is well under half the cost of a new system, repair. If it is older, on R-22, or facing a compressor failure, replacement is usually the smarter spend. The thing worth knowing before you decide: replacing the AC is the natural moment to price an air-source heat pump instead — it cools exactly like an AC, adds efficient heating, and unlike a plain AC it qualifies for Ontario rebates. We lay out both numbers so you can choose with the full picture. See our AC installation and heat pump pages for the detail.

The usual cause is a clogged condensate drain. Your AC pulls moisture out of the air as it cools, and that water normally drains away through a line — when that line clogs with algae or debris, the water backs up and overflows the pan onto the floor. Clearing the drain fixes it. Other causes are a frozen coil that has thawed and overwhelmed the pan, a cracked pan, or a failed condensate pump. If you see water pooling, shut the AC off so it does not keep adding to it, and call us.

In most cases during summer, yes. We run 24/7 and prioritize no-cooling calls during heat waves, and our trucks carry the common parts — capacitors, contactors, motors — so a lot of repairs are done in one visit. We cannot promise same-day on every call, especially the busiest stretches or for a part that has to be ordered, but we will give you a straight answer on timing when you call (647) 491-6009.

If the AC is old and the repair is expensive, it is worth pricing. An air-source heat pump cools your home in summer exactly like an air conditioner and heats it efficiently through most of the year on top. The part that changes the math: a standard AC earns no rebate, but a qualifying cold-climate heat pump can earn up to $7,500 through Ontario’s Home Renovation Savings Program, so after the rebate it can land close to the cost of a like-for-like AC while doing more. It is not the right call for every home or budget — we confirm what yours qualifies for and lay the numbers side by side.

Yes. We repair central air conditioners, ductless mini-splits, and window units from every major brand, including Lennox, Carrier, Goodman, Trane, Rheem, Daikin, Mitsubishi, and Fujitsu.
