Your commercial HVAC system is a critical component of your Raleigh, NC company’s success. Without it, you’d never be able to carry on the necessary functions that keep your operation running smoothly. That’s why it makes good business sense to keep an eye out for signs of an impending malfunction. When you notice these signs, promptly schedule an appointment with a qualified commercial heating repair specialist. Here are a few of the major signs to watch for:
1. Heating or Cooling System Short Cycling
If your commercial HVAC system has suddenly begun cycling on and off repeatedly without bringing the indoor temperature into a comfortable range, this is a sign that something is wrong. Short cycling will cause your commercial air conditioner, heat pump, furnace or boiler to work extra hard in a futile attempt to cool or warm the workspace. Common causes of short cycling include a clogged air filter, frozen AC evaporator coil, improper refrigerant charge, cracked furnace heat exchanger or malfunctioning boiler pressure control gauge. If your commercial system is short cycling, it’s important to correct the problem promptly.
2. Deteriorating Humidity Control
A sudden loss of adequate humidity control is another sign that your system needs professional attention. Often, this issue occurs in conjunction with AC system short cycling, as the continuous on-off cycling causes the system to turn off before it removes sufficient humidity from the air. Poor humidity control can also be caused by a malfunctioning thermostat, though other, more complex, issues could also play a role.
3. Excessively Noisy Operation
If highly unusual whining, buzzing, scraping or grinding noises become the soundtrack of your workday whenever the HVAC system kicks on, it’s time to have the system looked at by a commercial heating repair pro. These noises can indicate anything from a loose internal part to a faulty control or other serious malfunction in the system.
If the problem is serious and your system is too old for repair to be practical, there’s good tax news. But, otherwise, you’re probably better off repairing than replacing.
