Fast response in summer

In peak season, often as soon as the day after tomorrow. We plan our schedules around the heat wave that is coming.

Price before the job

Even in the middle of a heat wave, the rate is given to you before we head out. No surprises on the invoice, whatever the hour.

Repair or replace, honestly

If the unit is out of warranty and repairing approaches the cost of a new one, we do the honest math with you.

An air conditioner quitting during a heat wave cannot wait

When it is 32 degrees and your air conditioner is blowing lukewarm air, every day counts - especially if there are children, elderly people or someone vulnerable at home. The problem is that in the middle of a heat wave everyone calls at once, and plenty of repair companies are swamped or charge a fortune by taking advantage of the urgency.

The most common air conditioner failures are identifiable: low refrigerant (often a leak) making it blow warm air, a water leak when the drain is clogged, a frozen evaporator coil, or a capacitor giving out and keeping the unit from starting. Central or wall-mounted, the principle is the same: we find the cause before pricing it.

The central versus wall-mounted distinction still matters. A central air conditioner pushes cold air through the home's ductwork: its failures involve the outdoor condensing unit, the coil in the furnace, or the airflow. A wall-mounted unit (or a heat pump in cooling mode) has everything in two units linked by refrigerant lines. We repair both, and we always start with the same reflex: understand why, before touching anything.

How we work in summer: we plan our schedules around the season, which lets us respond fast - often as soon as the day after tomorrow - and the price is given to you before we head out, even in the middle of a heat wave. No disguised surcharge because it is hot and you are stuck.

Air conditioner repair is part of Air 2's HVAC repair silo: a human answers, the price comes before the job, and our in-house team is on site.

The air conditioner failures we see most

Warm air, leaking, icing up: each one has a precise cause that we diagnose before giving you a price.

It blows warm air

Most often low refrigerant caused by a leak. We actually hunt down the leak before recharging, otherwise it starts over.

It leaks water

Clogged condensation drain or a frozen coil thawing out: the water overflows instead of draining. We clear it and find the cause.

It ices up

A coil covered in ice usually comes from low refrigerant or blocked airflow. Melting it fixes nothing without the cause.

It will not start

Capacitor, contactor or an electrical problem: the unit stays silent or hums without starting. We test and tell you what it needs.

"In the middle of a heat wave, everyone is swamped or charges a fortune"

That is often true, and it is exactly what we decided not to do. A heat wave is not an excuse to inflate prices or make someone sweltering wait a week. We plan our schedules ahead of the season, which lets us respond fast when demand explodes - often as soon as the day after tomorrow.

And the price? Given before we head out, heat wave or not. The rate does not go up because it is 35 degrees and you are stuck - that would be exploiting the urgency, and it is not how we work. You know what you are paying before we come out.

On an old air conditioner out of warranty, we also do the honest math with you: if the repair approaches the cost of a new unit, we tell you. And since the LogisVert rebate does not cover an air conditioner on its own but does cover a heat pump, replacing with a heat pump sometimes comes out barely more expensive while giving you heating as a bonus. If you decide to replace, we also handle air conditioner installation.

Frequently asked questions about air conditioner repair

The most frequent cause is low refrigerant, almost always due to a leak. Recharging without finding the leak only pushes the problem back a few weeks, which is why we actually hunt down the leak before putting gas back in. It can also come from a struggling compressor or an electrical problem. We diagnose the real cause, then tell you the price before repairing.
An air conditioner normally produces condensation, which should drain away. When the condensation drain is clogged, the water overflows. Another frequent cause: a coil that froze and then thaws all at once, releasing more water than the pan can handle. We clear the drain, check why the coil is freezing if that applies, and fix the cause - not just the water on the floor.
It depends on the failure: a capacitor, a recharge with leak detection, or a major part are nothing alike in cost. So we do not throw out a blind number over the phone. We diagnose, we identify the cause, and we tell you the exact price before repairing. In peak season, the rate is the same as any other time - we do not take advantage of the heat wave, and any evening or weekend surcharge is stated up front.
An evaporator coil covering in ice most often comes from low refrigerant or insufficient airflow (clogged filter, weak fan, dirty coil). Thawing it fixes nothing if the cause remains: it will freeze again. We find out why it is freezing - and sometimes the answer is that a good coil cleaning would have fixed the airflow. That is the link with our air conditioner cleaning, which prevents exactly this kind of failure.
On a unit out of warranty, our benchmark is the cost of the repair against a replacement. And there is an angle specific to air conditioners: since the LogisVert rebate does not apply to an air conditioner alone but to a heat pump, replacing with a heat pump sometimes comes out barely more than a major repair, while giving you heating as a bonus. We show you the numbers for all three scenarios - repair, replace with an air conditioner, replace with a heat pump - and you choose.

(Translated by Google) We live in a condominium and suspected that one of the owners had a bird's nest in her dryer vent. Pierre-Alexandre came and did a thorough cleaning and was very respectful of nature, placing the three eggs he found under our cedar trees, along with part of the nest removed, in case the mother returned for her chicks. He did an excellent job working at heights (3rd floor) and we will definitely contact this company again if needed. Thank you, Pierre-Alexandre!

Nous sommes en copropriété et nous nous doutions qu'une des copropriétaires avait un nid d'oiseau dans son conduit de sécheuse. Pierre-Alexandre est venu faire un bon nettoyage et a été assez respectueux de la nature pour poser sous nos cèdres les 3 oeufs trouvés avec une partie du nid enlevé au cas où la mère reviendrait pour ses petits. Il a fait un excellent travail en hauteur (3e étage) et nous recontacterons assurément cette compagnie au besoin. Merci Pierre-Alexandre
