Out with the old, in with the reliable.

This old Goodman unit had a cracked heat exchanger — a serious safety concern and a clear sign it was time to go. When it comes to heat exchangers, there is no patching or shortcuts. Replacement is the right call every time.

We upgraded this home with a Rheem R962 two-stage furnace with a variable speed motor — a major step up in comfort and efficiency.

✔️ Two-stage heating for more consistent temperatures
✔️ Variable speed blower for quieter operation and better airflow
✔️ Improved efficiency and comfort control throughout the home

Installed with attention to detail, proper setup, and combustion safety as always.

If your furnace is showing signs of age or concern, it is worth getting it checked before it becomes a bigger problem.

Your comfort is our long run.

Not a service call you ever want to walk into.

😔😞😒😕😟

Someone hopped the fence, got into the backyard, and cut out about 18 inches of copper from this air conditioner to sell for scrap. That small piece of copper just turned into a major repair and a lot of stress for the homeowner.

I really feel for my client on this one. No one expects to deal with something like this, especially in their own backyard. It is an unfortunate reminder of how desperate things have become for some people.

Least the thieves could've done as at least pumped down the unit and closed the service valves. 🤪

Disappointing to see, but we will get them back up and running.

If your outdoor unit is easily accessible, it may be worth thinking about some added protection.

Last summer I took these photos on a service call, and seeing them again got me thinking about how important it is to do a proper install the first time.

This system had been slowly leaking refrigerant for years. This small flare leak went unnoticed. Eventually the charge dropped low enough that the system could no longer function.

We used a DR82 refrigerant detector to pinpoint the leak. It led us right to the flare connection. The flare had not been formed correctly, and it was never properly seated. A small detail, but it cost the homeowner years of performance and efficiency.

I cut it back and re-flared the connection using a NEF6LM flaring tool, made a clean, concentric flare, extra insurance with Nylog, torqued it properly, pressure tested, pulled a deep vacuum, weighed in the charge, and brought the system back to life.

Here is the lesson:
Flares are not just “good enough” connections. They must be precise. Clean copper. Proper depth. Smooth face. Correct torque. And always double-check your work before you connect a pipe. And always use the right tools!

In HVAC, small details become big problems if ignored.

Marathon HVAC officially hit the one-year mark, and it is hard to put into words how grateful I am. This first year has truly been a rollercoaster, filled with big wins, hard lessons, long days, and moments that tested resolve. Plenty of ups and downs, but every step has been worth it.

I am deeply thankful for every customer who trusted me, every supplier who answered questions, every fellow tradesperson who offered advice, and every friend and family member who supported this journey in one way or another. None of this happens alone.

This year reinforced why I started Marathon HVAC in the first place: to do honest work, take pride in quality, and build something that lasts. I am thankful for the growth, the challenges, and the lessons that will shape the years ahead.

Here is to continuing the long run.

Your comfort is our long run.

One year ago today — February 12, 2025.
This was the day I picked up the Marathon HVAC van.

We even gave it a name: Eliud Kipchoge, after marathon legend Eliud Kipchoge — a reminder to keep showing up, stay disciplined, and play the long game.

Looking back, it is honestly amazing to see how much has happened in just one year. Starting a business is a leap of faith, and this first year has been full of long days, lessons learned, and steady growth. I could not have imagined how well things would come together.

This van has treated me incredibly well. It has been there for early mornings, late nights, and countless service calls, even after the headaches and trouble that came with the dealership at the start. Once it was on the road, it just worked, and it has been a reliable partner every step of the way.

Grateful for the journey so far, the clients who trusted me in year one, and everything that is still ahead.
Your comfort is our long run. 🏃‍♂️🔧 🚙

Huge thanks to everyone who helped me get here — The Wrap Doctor, my buddy Jamie, my dear wife, and so many others who supported, encouraged, and believed in me along the way.

Tried the caricature trend. Kinda like this little guy! How does yours look?

Another Hisense mini-split in the wild ❄️🔥

One of the reasons this is our go-to mini-split is simple: Hisense designs, engineers, and manufactures their own equipment. No outsourcing. No rebadging. Just tight quality control from start to finish.

The design and engineering on these units is outstanding — quiet operation, clean layout, and thoughtful details that make installation and long-term reliability better for both the installer and the homeowner.

On top of that, this system is backed by a 10-year parts and labour warranty, giving real peace of mind long after installation day.

When we install a mini-split, we want confidence in what is behind the panel, not just what is on the label. This system checks all the boxes.

Your comfort is our long run.

Gave a hand to ultra talented crew at Siuperior Mechanical for a couple RTU units.

So glad the weather warmed up for these two beasts.
