Making your HVAC system work smarter.
- Keep things running smoothly by regularly cleaning evaporator and condenser coils, checking filters, and maintaining the correct refrigerant charge.
- Install timers or programmable thermostats to shut down or reset temperatures during non-business hours.
- Treat cooling tower water to prevent blockage and corrosion—this can shorten the life of your equipment, increase energy use and promote the growth of potentially hazardous microorganisms.
- Test, adjust and balance the system as needed to optimize performance and efficiency.
Is it time to upgrade?
If you’re following the above tips and notice your HVAC isn’t performing as it should, you may need a larger upgrade. Before considering a replacement, try these options:
- Install more efficient exhaust fans. Mixed flow impeller exhaust fans are about 25 percent more efficient than traditional centrifugal exhaust fans. They can also be cheaper to install and maintain.
- Add a heat pump. These can provide temperature control in smaller spaces that are occupied during off-hours without the need to operate the central system.
- Install an economizer cycle. Ideal for large buildings with areas requiring year-round cooling, an economizer cycle can use fresh-air cooling to reduce costs.
- Add a heat recovery system. These systems recover 45 to 65 % of the heat from exhaust air to reduce the energy required to heat or cool intake air.
- Convert to a variable air volume system. Such systems operate more effectively by adjusting airflow depending on demand.
