Maintenance Plans for Commercial HVAC Customers

Air Tech’s maintenance plans for commercial HVAC customers cover several very important items.

Unlike residential HVAC units, most commercial units are belt-driven.  One especially critical maintenance item for this type of unit is to grease the bearings and tighten the belts at least once every 3-4 months.  If this isn’t done, a bearing could wear out and cause a shaft to bend.  This could require replacing the shaft, blower or even a motor, which is a much more expensive repair. 

In addition to greasing the bearings and tightening the belts, the routine maintenance items covered by our plans includes:

  • Checking to make sure that units are in proper working order
  • Checking freon levels
  • Inspecting belts
  • Inspecting drains
  • Inspecting/replacing filters
  • Cleaning burners
  • Adjusting gas pressures
  • Checking and adjusting pilot operation
  • Lubricating all moving parts
  • Inspecting and tightening any loose electrical connections
  • Checking and testing safety controls
  • Adjusting air flow for proper temperature rise
  • Inspecting the thermostat
  • Monitoring the furnace cycle
  • Check for cracked heater exchanger
  • Checking to ensure voltage and amperage and electrical connections are accurate
  • Monitoring air conditioning cycle
  • Ensuring that delta-T is within 15-20 degree range

Types of Commercial HVAC Systems

A heating and cooling system for a large building can be very complex.  There are many different types of systems, but one of the most common in this area is a package unit that combines the gas heat and air conditioning into one unit that is outside the building. 

This allows for easier maintenance, as technicians can access the unit without having to disrupt work inside the building. 

Frequently Asked Questions for Commercial HVAC

Below are the answers to some of the frequently asked questions we get from our commercial HVAC customers.

Do you offer discounts for commercial customers?

Yes, if you sign up for a maintenance plan, we offer a $10/hr discount on labor and a 10% discount on parts.  You also get priority for maintenance emergencies.

What temperature should we set the programmable thermostat in our building to?

Most people find a temperature of about 72—75 degrees to be comfortable.  It is best to leave the temperature fairly constant, even when the building is empty, and not change it more than 4 degrees either up or down.  If the temperature varies by more than that, it will take more energy to get the temperature back to the original level than you would save by changing it.

How often should I have preventative maintenance done on my commercial HVAC system?

You should have your system inspected at least every 3-4 months, and have the belts tightened and bearings greased at that time as well (assuming it is a belt-driven system).
