Saving money on AC costs is fairly easy. If you follow some simple steps, you will notice differences in both basic AC costs and in employee productivity. You win both ways, because you benefit from lower costs and higher profits. Commercial HVAC systems are complex pieces of equipment that work long and hard to do their job. Many of those systems operate in less than perfect conditions, because commercial and industrial neighborhoods tend to be dirtier than rural or domestic ones. This brings us to the first and easiest way to cut your AC costs.
1) Clean the filter
Every particle of dust, pollen, vehicle exhaust emission and industrial smoke that is in the neighborhood air is sucked into the AC condenser unit. The filter is there to prevent all of this particulate matter from getting into the ductwork. A dirty filter limits cool air flow, the building is warmer than it should be, so the thermostat gets set to run at a lower temperature. This causes the motor to work harder, it increases electricity costs and it drags in more dust and grime. A maintenance contract will ensure your filters are clean, but you can do it yourself if you prefer.
2) Have a 6 monthly tune-up
The easiest way to keep overall costs down is to have professionals come in at the start of spring and fall to carry out comprehensive preventive maintenance work. Commercial HVAC maintenance contracts include complete system inspection, unit cleaning and preventive maintenance tasks. Properly maintained HVAC systems work more efficiently, more effectively, cost less to run, and last longer.
3) Clean the ductwork
No matter how often you replace the filter, the ductwork will accumulate grime. This has two effects. The first is that the system will burn more electricity to keep airflow at optimum levels, and the second is that your employees will be breathing in lower quality air.
4) Zone the building
If some parts of your building are used more than others, or if some parts have to be kept at a lower temperature than others, you can lower your overall AC costs by introducing zones. Different parts of the building will be kept at different temperatures, so the system will work at optimum load, not maximum load. Your AC specialist can explain the process to you. The investigation and installation can be built into regular commercial HVAC maintenance contracts.
5) Replace old units with high SEER units
New units have SEER ratings of anything from 13 to 23, and perform much better than old units with ratings of 8 to 10. The initial investment will be quickly returned by lower monthly running costs.
Commercial HVAC maintenance contracts are worth their weight in lower running costs, a longer system life and more productive employees.
