Here is a crispy relay on an air handling unit that cycles power to second-stage heat. While not needed this time of year, it’s good to find and repair things like this on planned maintenance & servicing programs.

The Cape Spear Cafe will be opening soon!
I was there yesterday to startup their refrigeration systems and make sure everything is working properly for the season!
Come up and have a snack, can’t beat these views 🥰

Smoke in the air all over Metro!
Everyone using an HRV should set it on OFF or RECIRCULATE.
Commercial buildings using a Rooftop HVAC unit should turn the economizer and cooling to OFF.

Who says pneumatic control systems are becoming obsolete?
Recently I had the privilege of servicing this zoning control system, where dampers that open and close using compressed-air-powered pistons are utilized to start and stop flow to different parts of the building.

New DC controller for this intake-air duct heater at One Centennial!

One of the isolation/service valves was leaking on this multi-zone ductless heat pump. Warranty support sent an entire new gas-side header.
What followed was a lot of disassembly, brazing, and rebuilding. Not for the faint of heart, but I enjoyed the challenge!

Re-build of a seized zone control valve. Sometimes you have to take it apart to find out WHY.
The motor was receiving power and the actuator was responding, but there was still no flow.
As I disassembled the old valve body, I found the ball was seized in place.

Pics from a system replacement that was done almost 2 years ago and never posted.
New Bosch condenser and air-handling unit, replacing a 15 year old Lennox, for which repairs were getting to be cost-prohibitive.
The new Bosch IDS condensing units are so compact and quiet!

Some repairs on a HABCO self-contained cooler at Cakey Hand Dessert Factory!

Recent service call: one section of the building was overheating.
Each zone has a motorized damper controlling airflow to a given area of the building. One damper had a motor which was seized in the open position, allowing excess heat to flow through.
I rebuilt the damper motor and checked for correct operation.
