A Properly Sized Commercial HVAC System Makes All the Difference 

Many people assume that the common slogan “bigger is better” applies to heating and cooling equipment. After all, why wouldn’t a bigger system result in better performance and comfort? However, an HVAC unit that is too large for a building can have a significant impact. Oversized HVAC systems tend to leave too much moisture in the air, causing the space to feel uncomfortable and humid. Excess moisture can also mean problems with mold and mildew. When a system is too large, it will turn on and off too frequently, causing excessive wear and tear on the unit, as well as driving up the amount owed on energy bills. 

Although having an HVAC system that’s too small is slightly better than having one that’s too big, undersized HVAC systems are also problematic. Units that are too small for the space struggle to reach the desired temperatures and often have to run non-stop just to keep up. This too can increase energy bills and cause a unit to break down completely long before its time.

How Long Should a Commercial HVAC System Last?

When properly maintained, commercial HVAC equipment can last 15 to 20 years. Even with regular service, some components such as the heat exchanger and evaporator coil may fail and need to be replaced to make the unit last longer. However, it’s important to stop using a system that is no longer able to perform efficiently, as this can waste money on extra energy consumption. It’s also a good idea to replace a unit if it requires frequent and costly repairs.   

Common signs that indicate it’s time to replace a commercial HVAC system include: 

  • Utility bills are rising unexpectedly 
  • Unusual noises such as grinding, or squealing are coming from the system
  • The unit is reaching the end of its expected lifespan 
  • Strange odors are emitting from the unit 
  • Unexplained swings in temperature or hot and cold spots throughout the building 
  • Excessive moisture on walls and windows 

 

The Benefits of Commercial HVAC Maintenance 

Regular preventive maintenance for commercial HVAC equipment is the key to avoiding major problems and periods of downtime. HVAC systems that don’t receive adequate maintenance often develop serious issues over time, which can lead to expensive repairs and even suspension of business operations.

Carrying out preventive maintenance on a commercial HVAC unit has several benefits, including: 

  • It minimizes equipment failure 
  • It reduces the frequency of major repairs 
  • It can significantly increase the lifespan of the system 
  • It enhances the efficiency of the equipment 
  • It decreases the amount owed on monthly utility bills 
  • It improves indoor air quality 
  • It increases productivity in the workplace 

 

It is recommended that commercial HVAC maintenance take place at least twice annually. During the service appointment, the technician will perform several essential tasks, including cleaning, testing, and calibrating system components. At D&R Heating & Air we offer preventative maintenance agreements for all types of equipment, including rooftop units, boilers, chillers, compressors, and makeup air units.
