What are commercial HVAC services?

Commercial HVAC refers to heating, ventilation, and air conditioning systems used in larger or more complex buildings like schools, offices, hospitals, and factories. These systems regulate temperature, airflow, and air quality at scale – often across multiple zones or floors.

What services do commercial HVAC contractors provide?

Commercial HVAC contractors install, maintain, and repair heating, cooling, and ventilation systems. This may include new system design, emergency repairs, planned maintenance, and upgrades for energy efficiency or compliance purposes.

How often should I have my commercial HVAC system serviced?

It depends on the building and system, but we recommend servicing most commercial HVAC systems annually at least – ideally before peak heating and cooling seasons. Regular maintenance helps prevent breakdowns, improve efficiency, and extend the system's life.

What's the difference between residential and commercial HVAC?

Commercial HVAC systems are more complex, often custom-designed, and built to handle much larger spaces. They typically involve zoned heating and cooling systems, rooftop units, or industrial-grade boilers which require specialist installation and servicing.

How do I choose the right commercial HVAC services contractor?

Look for a contractor with relevant accreditations (like CHAS and Gas Safe), strong case studies, and experience with your type of site. Quick response times, clear communication, and a flexible approach are key – especially if you work in live environments.
