Depending on the type of business you operate, you may use the air conditioning system all throughout the year. But for the majority of smaller businesses (in this case, ones with commercial HVAC units 25 tons and under), the middle of the year is when the cooling systems run the most frequently. Along with their steady operation comes an increase in electrical use. That’s normal; it’s exactly what you expect to see on monthly bills in summer.
But what we’re addressing today is when those bills rise higher than you’re used to seeing. If you compare your current bills to the same ones from the same time over the last few years, and discover you’re paying far more, it’s worth investigating. If it isn’t because of an increase in energy costs or an expansion of your business, you may need service from our professionals for your commercial air conditioning in Everett, WA.
Let’s examine some of the reasons why you may have this spike in cooling costs.
This is one of most common malfunctions in rooftop air conditioning and heat pump systems, and it’s often hard to recognize when it starts. A loss of refrigerant will eventually affect cooling power in a facility, but that won’t be the first symptom you’ll notice. The drop in refrigerant charge will force the AC to work harder and raise costs. You must have leaking refrigerant fixed ASAP, because it will cause catastrophic damage if left unchecked, leading to a full system replacement.
Malfunctioning thermostats and building controls
You may have only one thermostat for your business. You may have a network of them automated through building controls. Wherever your facility sits on this spectrum, faulty thermostats and controls can lead to a plunge in energy efficiency. It only takes one thermostat to start to misread temperatures to cause the AC to run at the wrong times and waste power. Professionals can track down where the problem originates and see what repairs and upgrades will correct it.
Lack of maintenance
Unfortunately, we come across this one too often, and it’s easy to avoid. Commercial HVAC equipment must be on a regular maintenance schedule, with AC maintenance done at a minimum of once a year. Missing maintenance will cause a decline in efficiency, and it only takes a few missed appointments to result in a 10% to 25% increase in cooling costs. We can help you set up a reliable maintenance program for all your heating and cooling equipment that will help them maintain energy efficiency through most of their services lives.
Most commercial HVAC units have a service life of around 15 years, with some variation based on how often it’s used. But 15 is fairly standard for units that receive regular maintenance. When you have equipment that’s older than this, any rise in cooling costs may be sending the signal that the time has come to schedule a replacement system. You can rely on our technicians to give you an honest appraisal of your HVAC units and whether you need to have them replaced or not.
