Air Conditioning in Sports Centers: How Poor Ventilation Can Drive Away Up to 30% of Members

Neglected air conditioning can seriously harm member loyalty

In a sports center, indoor air plays a far more crucial role than one might think. Inadequate temperature, poor air circulation, high humidity levels… these factors can not only deteriorate the customer experience but also directly impact member retention rates. Based on insights from our HVAC projects at AirGreen, up to 30% of a fitness center’s members may consider not renewing their subscription if thermal comfort and indoor air quality are neglected.

At AirGreen, we’ve supported numerous sports facilities in Montréal, Laval, Longueuil, the North Shore and the South Shore, helping them correct poorly designed ventilation systems, improve energy performance, and restore optimal comfort for both members and staff.

Why are air conditioning and ventilation vital in sports centers?

An improperly configured HVAC system in a fitness facility leads to a host of issues: lingering odors, window condensation, stagnant heat zones, and even mold growth. Physical activity raises body temperature, increases perspiration, and amplifies the need for air exchange. A well-maintained and efficient ventilation system is therefore essential.

AirGreen case study: full HVAC renovation of a CrossFit gym in Laval

One of our recent projects in Laval perfectly illustrates the consequences of poor ventilation. The owner of a CrossFit gym contacted us after receiving repeated complaints from members about the "stuffy" air during peak training hours.

Initial assessment

• Uneven air conditioning throughout the various training areas

• No mechanical air exchange system (no ERV)

• Excess humidity and visible condensation on walls

• Outdated HVAC equipment, not suited to the facility’s actual needs

Our custom solution

1. Installation of a 3-Ton Bosch BOVA central heat pump, compatible with R-454B refrigerant, with independent zone distribution

2. Integration of a high-efficiency ERV (Energy Recovery Ventilator) with heat recovery, adjusted for real-time occupancy

3. Complete revision of the duct network: insulation, airflow balancing, new air diffusers

4. Implementation of a smart control system using connected thermostats and CO2 sensors to automate ventilation based on air quality

Tangible results

• Notable improvement in air quality from the very first week

• Relative humidity maintained between 45% and 55%, even during high-traffic periods

• Positive feedback from members: many noted the new thermal comfort and the constant freshness throughout the space

• Projected annual energy cost savings of 28% thanks to the high-efficiency equipment

Common HVAC mistakes in sports facilities

1. Using underpowered residential wall-mounted units

Many gyms still rely on wall-mounted AC units designed for single-family homes. These systems lack both the cooling power and the durability required for intensive commercial use.

2. Skipping mechanical ventilation

The absence of an ERV or HRV system in high-traffic environments leads to CO2 build-up, strong odors, and a feeling of suffocation among users.

3. Neglecting regular HVAC maintenance

Clogged filters, dirty coils, imbalanced fans: these issues harm heat pump performance, generate irritating noise, and spike energy consumption.

How AirGreen supports sports center managers

At AirGreen, we understand the unique challenges of HVAC installation in active training environments. Our experts tailor solutions to each space based on:

• Total floor area and ceiling height

• Average daily occupancy levels

• Type of activities (weightlifting, cardio, hot yoga, etc.)

• Zones with distinct climate needs (locker rooms, showers, common areas)

We deliver turnkey professional solutions, from HVAC system design to certified installation, plus preventive maintenance and fast repairs. All our setups are designed to meet or exceed Québec’s energy standards, including eligibility for Hydro-Québec LogisVert grants.

Preferred technologies used by AirGreen

• GREE Sapphire commercial wall-mounted heat pumps: high efficiency, quiet operation, BTU range adapted to large open areas

• Lennox Varix VRF systems: ideal for multi-zone complexes with independent temperature control

• VENMAR HEPA 700 Series ERVs: advanced filtration to ensure clean air in high-exertion areas

Subsidies and energy efficiency: a winning combination

Thanks to our equipment using eco-friendly refrigerants like R-32 and R-454B, most of our installations qualify for grants of up to $2,400 in some cases. We guide our clients through the entire LogisVert grant application process, providing all required documentation.

The importance of professional follow-up and maintenance

Even the best wall-mounted or central heat pump won't deliver performance without regular maintenance. At AirGreen, we recommend a semi-annual maintenance plan that includes:

• Cleaning filters and air exchangers

• Checking refrigerant pressures

• Testing airflow and temperature sensors

• Monitoring humidity levels and calibrating thermostats

We also provide fast, reliable after-sales service for all our commercial clients.
