Heat pump repair by someone who actually knows Oshawa
Oshawa's housing stock runs from older bungalows in Lakeview and Regent to mid-century homes in Centennial and O'Neill to newer builds in Kedron and Samac. Heat pump issues show up differently depending on the system's age, how it was installed, and how hard it's been working through Durham Region winters. Zack has been servicing heat pumps across Oshawa for years and works on all makes and models, not just systems he's installed.

All makes and models
We service Mitsubishi, Carrier, Lennox, Daikin, Bosch, and all other major brands. If it's a heat pump, we can diagnose it.

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 heat pump needs a service call
Heat pumps run year-round, so problems can show up in any season. Here's what to watch for:
Not heating or cooling properly
If the system runs but output doesn't match the thermostat setting, there's usually a refrigerant, airflow, or sensor issue worth diagnosing.
Ice buildup on the outdoor unit
Some frost in heating mode is normal. Ice that doesn't clear typically points to a refrigerant issue or a faulty defrost control.
Unusual noises
Grinding or rattling from the indoor or outdoor unit are early warning signs. Catching them early is almost always cheaper than waiting.
Short cycling
Turning on and off every few minutes puts serious wear on the compressor. Usually a refrigerant, airflow, or control board issue.
System running constantly
A heat pump that never reaches the set temperature and runs non-stop is working harder than it should, often due to low refrigerant or dirty coils.
Sudden spike in hydro bills
A system working harder than it should shows up on your utility bill before it fails. Worth catching early before a small issue becomes a big one.
Repair or replace?
If your heat pump is under 10 years old and the repair is reasonable, fixing it almost always makes sense. If it's 12 to 15 years old and needs a significant repair, replacement is worth a conversation, especially with the HRS rebate potentially covering up to $7,500 of a new installation. Zack will give you an honest answer either way.
What to expect from a repair call
Here's how a typical heat pump repair goes from first call to working system.
You call or text, we respond quickly
Heat pump calls get priority. We'll give you an honest ETA and show up when we say we will.
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.
Honest repair or replace recommendation
We'll tell you whether fixing it makes financial sense or whether the money is better put toward a new system. No pressure either way.
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.
Full test before we leave
We run the system and confirm it's performing correctly before we close up. If anything isn't right after we're gone, call us.

A note from Zack
Heat pump repairs require a bit more diagnostic work than a straightforward furnace or AC issue. The system runs in both heating and cooling modes, the refrigerant circuit is more complex, and the defrost controls add another layer. I've been working on heat pumps long enough to diagnose them efficiently and tell you honestly what's going on.
Oshawa is home base for me. I've serviced heat pumps in the older homes in Lakeview and Regent, the mid-century properties in O'Neill and Centennial, and the newer builds out in Kedron and Samac. If your heat pump is acting up, call me directly and I'll tell you what's wrong and what it'll take to fix it.
