Commercial equipment Don works on

Rooftop air conditioning
Rooftop units that cool offices and commercial spaces from above: installation, repair and seasonal servicing.
See the Oshawa rooftop air-conditioning project
Gas lines
Gas piping to heating equipment and rooftop units in commercial buildings.
See the Hamilton office gas line project
Furnaces and heating
Gas and electric furnaces serving offices, shops and other commercial spaces: repair, maintenance and replacement.
Ventilation and indoor air quality
Ductwork and airflow, so fresh air reaches the rooms people use and stale air leaves them.
Maintenance
Scheduled servicing of heating and cooling equipment, planned around how the building is used.

What to tell Don about your building

A short written brief helps Don understand the job before the first visit. You do not need every detail. Send what you know and he can ask about the rest.

The property
- What kind of building it is (office, retail, industrial, multi-unit) and roughly how big
- The address or city, so Don can tell you whether he can serve it
- Whether the space is occupied, and by whom
The system and equipment
- What the equipment is: rooftop unit, furnace, gas line, ductwork or ventilation
- Approximate age, and the make and model from the rating plate if you can read it safely
- What it is doing, or not doing, and when the problem started
Access
- Roof access: hatch, ladder or stairs, and who holds the key
- Mechanical room location and keys
- Security sign-in, parking and loading arrangements
- Any notice tenants need before work starts
Timing
- Windows when work can happen with the least disruption
- Times to avoid, such as business hours in occupied spaces
- Who Don should coordinate with on the day

Rooftop air conditioning unit for an Oshawa building

Don’s HVAC Services completed rooftop air-conditioning work for a commercial building in Oshawa. Rooftop units serve the building from above, so the work involves roof access and coordinating with the people who manage the property.
