AC repair by someone who actually knows Ajax

Ajax summers get hot fast, the humidity rolls in and a broken AC goes from inconvenient to miserable in hours. Ajax's housing stock ranges from older homes near Bayly Street and Pickering Village to newer subdivisions along Rossland and Taunton. Zack has been servicing AC systems across Ajax for over 15 years and services all makes and models.

Fast response

Based in Durham. No waiting on a crew from out of town. AC calls in summer get priority, especially during heatwaves.

Honest diagnosis

We tell you exactly what's wrong and what it'll cost before any work starts. If it's not worth fixing, we'll tell you that too.

All makes & models

We service Trane, Carrier, Rheem, Lennox, Goodman, and all other major brands. If it's an AC unit, we can diagnose it.

No upselling

A repair call is a repair call. We won't push you toward a replacement you don't need just because it's a bigger job for us.

Signs your AC needs a service call

Some problems are obvious. Others show up quietly before a full breakdown. Here's what to watch for:

Warm air from the vents

Low refrigerant, a dirty evaporator coil, or a compressor issue, all repairable depending on the system's age and condition.

House won't cool down

Could be a refrigerant leak, blocked airflow, dirty filters, or a sizing issue. Worth a diagnostic before assuming the worst.

Water leaking near the unit

Usually a blocked condensate drain, often a simple fix. Can also indicate a frozen evaporator coil.

Unusual noises

Banging suggests a loose or broken component. Buzzing often points to electrical issues. Rattling can be debris or a loose panel.

Short-cycling

Turning on and off frequently puts serious wear on the compressor. Usually an oversized unit, dirty filter, or refrigerant issue.

Sudden hydro bill spike

A system working harder than it should, often a maintenance issue that gets worse over time if left unchecked.

Repair or replace?

If your AC is under 10 years old and the repair is under 50% of a new system's cost, repair almost always makes sense. If it's 12–15+ years old and needs a major fix, replacement is worth considering, especially if a heat pump could serve you better. Zack will give you an honest answer either way.

What to expect from a repair call

Here's how a typical AC repair goes from first call to cool home.

1

You call or text. We respond quickly

AC calls in summer get priority. We'll give you an honest ETA and won't leave you in the heat waiting for a callback that never comes.

2

Diagnosis first, quote before work begins

There's a service call fee to come out and diagnose. Once we know what's wrong, you get a clear quote. Nothing starts until you approve it.

3

Honest repair or replace recommendation

We'll tell you whether fixing it makes financial sense or whether the money is better spent on a new system. No pressure either way.

4

Repair completed, usually same visit

Most repairs are done the same day. If a part needs ordering we'll tell you upfront and follow up as soon as it's in.

5

Full test before we leave

We run the system and confirm it's cooling properly before we close up. If anything isn't right after we're gone, call us.

A note from Zack

Zack heading out on a job in Durham Region

When your AC goes down in July, you don't have time for contractors who take days to call back. I prioritize summer AC calls and give you an honest ETA, not a vague 'sometime this week.'

I've been working in Ajax for years, from the older homes near Pickering Village to the newer builds up along Taunton. If your AC is down, call me directly.

Frequently asked questions

How quickly can you get to me in Ajax?

We're based in Durham Region and service Ajax regularly. AC calls in summer get priority, call or text and we'll give you an honest ETA.

Do you charge a diagnostic fee?

Yes, there's a service call fee to come out and diagnose the issue. If you proceed with the repair, that fee is applied toward the total cost of the job.

What AC brands do you service?

We service all major brands including Trane, Carrier, Rheem, Lennox, Goodman, and Bryant. If it's an air conditioner, we can diagnose it.

My AC is running but not cooling, what's likely wrong?

The most common causes are low refrigerant, a dirty evaporator coil, or a failing compressor. It could also be as simple as a dirty filter restricting airflow. Worth a diagnostic, some of these are inexpensive fixes, others are a sign it's time to consider replacement.

Do you service north Ajax? Rossland Road, Taunton Road area?

Yes. We cover all of Ajax including the newer subdivisions in the north end. Same response time, same owner, same service wherever you are.

At what point does it make more sense to replace than repair?

If your AC is under 10 years old and the repair is under 50% of a new system's cost, repair almost always makes sense. If it's 12–15+ years old and needs a significant fix, replacement is worth a conversation. We'll give you an honest answer either way.
