Frequently Asked Questions
DO YOU OFFER EMERGENCY COMMERCIAL HVAC REPAIRS?
Yes, we understand that heating or cooling failures can completely halt your operations. CORH provides prompt, reliable emergency repair services for businesses across Innisfil and Simcoe County. Our certified technicians arrive quickly to diagnose and resolve critical issues, minimizing your downtime and protecting your bottom line.
HOW OFTEN SHOULD COMMERCIAL HVAC SYSTEMS BE SERVICED?
For optimal performance, we recommend comprehensive preventative maintenance at least twice a year—once before the winter heating season and once before summer. However, high-demand facilities or environments with heavy airborne particulates, like manufacturing plants, may require quarterly servicing to prevent costly, unexpected breakdowns.
WHAT TYPES OF COMMERCIAL HVAC EQUIPMENT DO YOU SERVICE?
Our certified technicians are highly trained to service, repair, and install a wide range of heavy-duty industrial equipment. This includes packaged rooftop units (RTUs), commercial boilers, chillers, cooling towers, make-up air units, heat pumps, and specialized production heating systems for facilities of all sizes.
WILL HVAC REPAIRS DISRUPT MY DAILY BUSINESS OPERATIONS?
We strive to make our service calls as seamless as possible. The CORH team works efficiently and coordinates directly with your facility managers to schedule necessary repairs during low-impact times whenever feasible. Our goal is to safely restore your climate control without interrupting your employees or customers.
SHOULD I REPAIR OR REPLACE MY AGING COMMERCIAL UNIT?
If your equipment is over 15 years old, constantly requires expensive repairs, or operates inefficiently, replacement is often the better long-term investment. We provide honest, detailed ROI assessments to help local business owners decide whether a targeted repair or a high-efficiency system upgrade makes the most financial sense.
HOW CAN I LOWER MY FACILITY'S HEATING AND COOLING COSTS?
The most effective way to reduce utility bills is through routine preventative maintenance. Clean coils, lubricated parts, and calibrated thermostats ensure your system doesn't overwork. Additionally, our technicians can recommend programmable commercial controls or modern, high-efficiency equipment upgrades to drastically reduce your long-term energy waste.
