Customer Testimonials

Section divider with Cahill Logo

"We rented Cahill heaters as part of our winterization plan. The Cahill heaters helped us power through our winter operations when the temperature dipped below -30 degrees Celsius consistently.

Cahill's technicians were always on site when needed and also performing routine service checks. The heaters barely had to be taken offline and this helped us keep our project running.

We received better service response with Cahill with a telephone operator available round the clock to perform any troubleshooting if needed. Cahill's service was a huge improvement from other vendors we have used in the past."

"I wish we had used Cahill’s flameless heaters all along. The CH15HS is absolutely with no doubt a brilliant heater. They have 20" of static pressure and you can run duct 500' with this pressure.

We rented 13 of Cahill's flameless heaters for the American Dream in the winter of 2018. It helped us power through winter construction with no issues.

After calculating the loads, we ran flexible duct with a 3" crosshair. The flexible duct against the outer wall was hot therefore warming the cold outer exterior walls which were a very large surface area that would transmit cold into the building. The building was nice and warm for the winter.

Cahill offers the best heating solutions hands down for big construction jobs. The diesel burns with the highest efficiency with no fouling gases."
